Opis:
This work was undertaken to compare cytotoxicity, DNA damaging properties and effect on DNA cleavage by topoisomerase II of the anthracycline drug doxorubicin (DOX) and its two derivatives with a formamidino group containing a cyclic amine moiety such as morpholine (DOXM) or hexamethyleneimine (DOXH). The tetrazolium dye colorimetric assay was used to determine the cytotoxic activity of anthracyclines toward L1210 leukemia cells. DNA damage was measured by alkaline elution technique. The effect of anthracyclines on DNA cleavage was studied in a cell-free system containing supercoiled pBR322 DNA and purified human topoisomerase II. The cytotoxicity data and the results of studies on the mechanism of DNA break formation by anthracyclines at the cellular level and in the cell-free system showed that the presence of the formamidino group in the doxorubicin molecule reduced its ability to stimulate DNA cleavage by DNA topoisomerase II. Conclusion: DNA topoisomerase II is not a primary cellular target for DOXM or DOXH. An advantageous feature of formamidinoanthracyclines is their mechanism of cytotoxic action which is not related to the inhibition of DNA topoisomerase II. Therefore this class of anthracyclines seems to be a good source for selection of an anticancer drug directed toward cancer cells with the developed multidrug resistance attributed to the presence of altered DNA topoisomerase II.

Opis:
Chitosan (Chi) is an extremely promising natural biopolymer with remarkable potency for the development of drug and vaccine delivery nanosystems. Various Chi derivatives are used to form nanoparticles (NPs) with unique properties. However, the efficacy of the therapy delivered by Chi NPs depends significantly on NP biodistribution in the body. The aim of this study was the analysis of biodistribution of NPs formed by succinoyl Chi and loaded with doxorubicin (SCNPDOX). We compared the distribution of free DOX and SCNP-DOX after intravenous (i.v.) and intranasal (i.n.) delivery into tumour-bearing mice. Distribution of DOX and SCNP-DOX was comparable after i.v. injection while they differed significantly after i.n. instillation.

The results presented demonstrate the influence of aromatic indolinic aminoxyls: 1,2-dihydro-2-ethyl-2-phenyl-3H-indole-3-phenylimino-1-oxyl (IA-C2) and 1,2-dihydro-2-octadecyl-2-phenyl-3H-indole-3-phenylimino-1-oxyl (IA-C18) on oxidation of lipids and proteins of cardiac sarcoplasmic reticulum membranes. We have used doxorubicin and t-butyl hydroperoxide as agents inducing oxidative stress in isolated rat cardiac sarcoplasmic reticulum membrane system. Carbonyl groups were measured as the end product of membrane protein oxidation, and thiobarbituric acid reactive substances were assessed as a marker of lipid peroxidation. Inhibition of peroxidation of certain membrane components depends on the length of acyl chain. Aminoxyl IA-C2 inhibits the lipid peroxidation process while IA-C18 is an efficient protector against protein oxidation.

Opis:
Natural polyphenolic compounds produced by plant exhibit many pharmacological effects including antioxidant, chemopreventive as well as anticancer properties. This study was conducted to investigate the effect of cynarin ( from Artichoke, Cynara scolymus) and isoliquiritin (from Licorice, Glycyrrhiza uralensis) on doxorubicin (positive control) cytotoxicity in different cell lines including normal (Fibroblasts MCR-5 and Myoblasts H9c2) and cancer (colorectal HCT-116 and hepatocellular HEP-G2) cell lines. The cytotoxic effect of doxorubicin, isoliquiritin and cynarin alone or in different combination was studied on cancer cell lines as well as normal cell lines. The results obtained indicated that both cynarin and isoliquiritin enhance the cytotoxicity of doxorubicin. Both cynarin and isoliquiritin also reduce the cardiotoxicity of doxorubicin on normal cardiac cell lines. The combination of the three compounds (cynarin, isoliquiritin and doxorubicin) result in decrease the cytotoxicity of doxorubicin, which may indicate the presence of interaction and/or antagonism effect between cynarin and isoliquiritin. Cynarin was found to enhance the growth of (HCT-116 and HEP-G2) this might suggest avoiding use of Artichoke in subjects’ susceptibility for these cancers. All results were evaluated using statistical path and showed significant findings. The mechanism of enhanced doxorubicin’s cytotoxicity by cynarin or isoliquiritin also require further investigation to explain the increasing and/or the decreasing effect of these polyphenolic compounds on cytotoxicity of doxorubicin. The current finding can help to start with safe minimum dose of two or three combination of compounds in the context of clinical trials and practice.

Opis:
The study aimed to check the effectiveness of anticancer therapy combining a vascular-disruptive drug (combretastatin phosphate, CA4P) and a liposomal formulation of a chemotherapeutic (doxorubicin). CA4P was synthesized in our laboratory according to a previously described procedure. The antivascular drug and long-circulating doxorubicin-loaded liposomes were used to treat B16-F10 murine melanoma experimental tumors. Seventy-four hours after drug administration, a decrease in the number of tumor blood vessels was apparent and necrotic areas within tumors were visible. Combination therapy consisting of alternate administrations of CA4P and liposomal doxorubicin yielded greater inhibition of tumor growth than monotherapies alone. The best therapeutic results were obtained with the antivascular drug administered intratumorally every second day at 50 mg/kg body mass. In the case of combined therapy, the best results were obtained when the vascular-disruptive agent (CA4P) and the antineoplastic agent (liposomal doxorubicin) were administered in alternation.

Opis:
Previously performed experiments showed that methylxanthines, especially caffeine, may protect cells against cytostatic or cytotoxic effects of several aromatic compounds. One of the proposed mechanisms of this protection is based on stacking interactions between π electron systems of polycyclic aromatic molecules. In this work, we demonstrate that caffeine and other methylxanthines - pentoxifylline and theophylline - significantly decrease mutagenicity of the anticancer aromatic drugs daunomycin, doxorubicin and mitoxantrone. The spectrophotometric titration of these aromatic compounds by methylxanthines indicated formation of mixed aggregates. The concentrations of free active forms of the drugs decreased when the concentrations of methylxanthines increased in the mixture. Therefore, likely methylxanthines may play a role of scavengers of the free active forms of daunomycin, doxorubicin and mitoxantrone.

Opis:
W pracy przedstawiono wyniki badań uwalniania i degradacji in vitro do sztucznego płynu mózgowo- rdzeniowego (aCFS) dla wielowarstwowych matryc polimerowych zawierających doksorubicynę jako substancję leczniczą. Proponowany system terapeutyczny zbudowany jest z trzech warstw, tj. 2 zewnętrznych warstw kopolimeru glikolidu z ε-kaprolaktonem i 1 wewnętrznej warstwy kopolimeru glikolidu z D,L-laktydem z 10% zawartością cytostatyka. System wielowarstwowy utworzono przez kompresję w określonych warunkach: temperatury, nacisku i czasu. Postęp degradacji został potwierdzony przy pomocy zmian mikrostruktury łańcuchów metodą spektroskopii magnetycznego rezonansu jądrowego. Kinetykę uwalniania doksorubicyny z matryc jednowarstwowych i trójwarstwowych obserwowano przy pomocy spektroskopii UV-VIS. Zastosowanie trójwarstwowej matrycy pozwoliło na zmniejszenie początkowego wyrzutu leku z powierzchni nośnika polimerowego a tym samym zmniejszenie inhibicji uwalniania do 100 godzin eksperymentu.
In this work the results of in vitro release and degradation to artificial cerebrospinal fluid solution (aCFS) from multi-layered polymeric matrices containing cytostatic drug were performed.. The proposed therapeutic system was constructed from three layers: the glycolide/caprolactone copolymer were used in two external layers and glycolide/D,L-lactide copolymer in internal layer containing 10-weight % of cytostatic agent.. Three-layered drug release system was made by compression at suitable conditions of time, temperature and pressure. The degradation of three-layered polymeric matrices was confirmed on the basis of changes in copolymer chain microstructure using high resolution NMR spectroscopy. Kinetics of doxorubicin release from mono- and three-layered matrices was observed by UV-VIS spectroscopy. Application of three-layered matrix may be used to reduction of burst effect from polymeric carrier surface and to reduction of inhibition effect of doxorubicin release observed in first stage from mono-layered matrix.

Introduction: Sarcomatoid renal-cell carcinoma is a very rare cancer characterised with aggressive course of disease and poor prognosis. At present there are no standards of care for this histologic subtype of renal cell carcinoma resistant to various forms of systemic treatment. Methods: The study describes a case of 58 year old woman after left nephrectomy for clear cell carcinoma with sarcomatoid component and after resection of right-kidney tumour for synchronous clear cell carcinoma who received first-line bevacizumab and temsirolimus under the clinical trial, and then second-line chemotherapy based on gemcitabine and doxorubicin and ifosfamide-based third-line chemotherapy. The patient underwent pulmonary metastasectomy twice, and once a metastasectomy for liver metastases. Conclusions: Surgery (including metastases treatment) followed by the systemic chemotherapy seems to be correct option of treatment in patients with renal cell carcinoma with sarcomatoid features. The development of optimum method of systemic treatment requires further prospective randomised trials.

Opis:
Introduction and aim. Hydrogen sulfide (H2S) has attracted the attention of researchers as a novel signaling molecule that affects vascular metabolism, immune function, stress and inflammation. It plays an important role in pathophysiological disorders under the conditions of the development of obesity, diabetes, non-alcoholic fatty liver disease and cardiovascular diseases. The purpose of this work is to establish correlation ratios of H2S concentration with markers of oxidative-nitrosative stress and extracellular matrix metabolism of the liver during chronic alcoholic hepatitis modeling and AMPK modulation by phenformin and doxorubicin. Material and methods. The experiments were performed on 36 white, sexually mature male Wistar rats, weighing 180-220 g. Alcoholic hepatitis was modelled by alcohol administration, on the background of alcoholic hepatitis animals received phenformin orally at a dose of 10 mg/kg or doxorubicin at a dose of 1.25 mg/kg intraperitoneally. Statistical processing of the results of biochemical studies was carried out using the non-parametric method of Spearman to determine correlations. Results. H2S during alcoholic hepatitis inversely proportionally strongly correlates with the concentration of nitrites, oxyproline and arginase activity. Phenformin administration during alcoholic hepatitis leads to formation of inversely proportionally strongly correlation of H2S with the production of superoxide anion radical, the concentration of malondialdehyde, activities of constitutive NO-synthases, nitrite reductases, nitrate reductases, and arginase. Doxorubicin administration during alcoholic hepatitis leads to formation of directly proportional strongly correlation of H2S with the activity of constitutive NO-synthases, nitrite reductases, nitrate reductases. Conclusion. Administration of phenformin or doxorubicin expands correlations between H2S and indicators of oxidative-nitrosative stress.

Opis:
STI571 (imatinib mesylate; Gleevec®) is an inhibitor that targets the tyrosine kinase activity of Bcr-Abl present in chronic myelogenous leukemia (CML) cells. Some preclinical studies have demonstrated that the combination of STI571 with chemotherapeutic drugs results in enhanced toxicity in Bcr-Abl-positive leukemias. We investigated the potential benefit of using STI571 to down-regulate Bcr-Abl activity for the enhancement of doxorubicin anti-proliferative action in K562 cell line derived from blast crisis of CML. At low concentrations of both drugs (40 nM doxorubicin combined with STI571 in the range of 100-150 nM), the antiproliferative effects were mainly due to cellular differentiation as assessed by benzidine staining for hemoglobin synthesis level and real-time PCR for γ-globin expression. Higher concentrations of STI571 used in combinations with doxorubicin caused mainly apoptosis as shown by DNA degradation and nuclear fragmentation visualized by fluorescence microscopy after DAPI staining, changes in cell morphology observed after Giemza-May Grünwald staining and cellular membrane organization estimated by flow cytometry after Annexin V staining. As compared with either drug alone, cotreatment with STI571 and DOX induced stronger cellular responses. A low concentration of STI571 in combination with a low concentration of DOX might be tested as an alternative approach to increasing the efficacy of chemotherapy against CML.

Opis:
Neuroblastoma is the most common extra-cranial solid tumor of childhood and it is characterized by the presence of a glycosphingolipid, GD2 ganglioside. Monoclonal antibodies targeting the antigen are currently tested in clinical trials. Additionally, several research groups reported results revealing that ganglioside-specific antibodies can affect cellular signaling and cause direct cytotoxicity against tumor cells. To shed more light on gene expression signatures of tumor cells, we used microarrays to analyze changes of transcriptome in IMR-32 human neuroblastoma cell cultures treated with doxorubicin (DOX) or a mouse monoclonal antibody binding to GD2 ganglioside 14G2a (mAb) for 24 h. The obtained results highlight that disparate cellular pathways are regulated by doxorubicin and 14G2a. Next, we used RT-PCR to verify mRNA levels of selected DOX-responsive genes such as RPS27L, PPM1D, SESN1, CDKN1A, TNFSF10B, and 14G2a-responsive genes such as SVIL, JUN, RASSF6, TLX2, ID1. Then, we applied western blot and analyzed levels of RPS27L, PPM1D, sestrin 1 proteins after DOX-treatment. Additionally, we aimed to measure effects of doxorubicin and topotecan (TPT) and 14G2a on expression of a novel human NDUFAF2 gene encoding for mimitin protein (MYC-induced mitochondrial protein) and correlate it with expression of the MYCN gene. We showed that expression of both genes was concomitantly decreased in the 14G2a-treated IMR-32 cells after 24 h and 48 h. Our results extend knowledge on gene expression profiles after application of DOX and 14G2a in our model and reveal promising candidates for further research aimed at finding novel anti-neuroblastoma targets.

The ability of aqueous extracts of sclerotia of Pleurotus tuberregium and leaves of Cnidoscolus aconitifolius to regulate plasma markers of kidney and liver function/integrity was investigated in doxorubicin-treated Wistar rats. Doxorubicin (dissolved in normal saline) was injected intraperitoneally (15 mg/kg body weight) into the rats; metformin was daily administered orally at 250 mg/kg, while the extracts were daily administered orally at doses of 50, 75, and 100 mg/kg. Compared to the test control, in both the doxorubicin pre-treatment (or ameliorative) study and the extract pre-treatment (protective) studies, the extracts and metformin-treated groups had significantly lower (P < 0.05) plasma levels of alkaline phosphatase, alanine transaminase and aspartate transaminase, and concentrations of creatinine, urea, and blood urea nitrogen. However, the plasma globulin, albumin, and total protein concentrations and the albumin/globulin ratio of the extract and metformin-treated groups were significantly higher (P < 0.05). The extracts prevented (in the protective study) or attenuated (in the ameliorative study) doxorubicin-induced increase in the levels of plasma markers of kidney and liver function/integrity, and afforded protection or recovery towards near-normal values.

This study investigated the potential protective role of aqueous leafextracts of Chromolaena odorata and Tridax procumbens against pulmonary toxicity induced by doxorubicin. To this end, the effects of these extracts on the profiles of pulmonary biomarkers, lipids and electrolytes were monitored in doxorubicin-treated rats. Doxorubicin was intraperitoneally administered at 15 mg/kg body weight (48 h prior to sacrifice); metformin was orally administered daily at 250 mg/kg body weight (for 14 days); and both extracts were orally administered daily at 50, 75 and 100 mg/kg body weight (for 14 days).The concentrations of pulmonary malondialdehyde, cholesterol, triglyceride, calcium, chloride and sodium of Test control were significantly higher (P < 0.05) than those of the other groups. However, the concentrations of pulmonary ascorbic acid, reduced glutathione, magnesium and potassium as well as pulmonary catalase, glutathione peroxidase and superoxide dismutase activities of Test control were significantly lower (P < 0.05) than those of the other groups.The administration of the extracts prevented doxorubicin-induced adverse alterations in the profiles of pulmonary biomarkers of oxidative stress, cholesterol and electrolytes and maintained them within the normal ranges .Therefore, these herbal preparations from C. odorata and T. procumbens are promising candidates for the prevention/alleviation of doxorubicin-induced pulmonary toxicity.

The objective of this study was to demonstrate diff erences in the gene expression of human cervical cancer cells (HeLa) and vinblastine-resistant KB-V1 subline treated with doxorubicin alone and combination of Selol 5% and doxorubicin. Ongoing studies seek to clarify the mechanism of action of Selol in diff erent types of cancer cells, including those which show multidrug resistance. Cells treatment with the tested compounds in the group of genes tested in HeLa cells causes other changes than in KB-V1 cells. In the resistant cells, exposure to Selol 5% and doxorubicin, released the cytotoxic eff ects by changing the expression of ABCC2 and BCL2L1 genes. The observed dependence also allows better understanding the molecular mechanisms of resistance in the KB-V1 cell line.
Celem pracy było wykazanie różnic w ekspresji genów komórek ludzkiego nowotworu szyjki macicy (HeLa) i opornej na winblastynę podlinii KB-V1, poddanych działaniu samej doksorubicyny oraz po łącznym podaniu Selolu 5% i doksorubicy. Prowadzone badania zmierzają do wyjaśnienia mechanizmu działania Selolu w różnych typach komórek nowotworowych, w tym opornych wielolekowo. Poddanie komórek działaniu testowanych związków powoduje inne zmiany w grupie badanych genów w komórkach HeLa niż w komórkach KB-V1. Łączne podanie Selolu 5% i doksorubicyny wyzwala efekt cytotoksyczny w komórkach opornych KB-V1, co przypuszczalnie jest związane ze zmianą ekspresji genów ABCC2 i BCL2L1. Zaobserwowana zależność pozwala także lepiej zrozumieć molekularne podłoże oporności komórek linii KB-V1.
