Two recently synthesized groups of acridine cytostatics containing fused heterocyclic ring(s): pyrazoloacridines (PAC) and pyrazolopyrimidoacridines (PPAC) were tested in regard to their in vitro cytotoxic activity towards a panel of sensitive and resistant human tumor cell lines. The obtained results corroborate our earlier hypothesis on the essential role of heterocyclic ring fused to the acridine moiety in the ability of acridine cytostatics to overcome multidrug resistance of tumor cells. The presence, location and kind of substituents considerably influenced both the cytotoxic activity of the derivatives and their ability to overcome multidrug resistance. The same factors also affected the cytostatics ability to differentiate between tumor cell lines with various types of drug exporting pumps.

The cytotoxic activity of petroleum ether extract of the leaves of Cassia roxburghii Linn. against HCT-116 and MCF-7 cell lines resulted with IC50=34.9 and 38.04 μg/ml, respectively, while against HepG-2 showed no activity. A bioassay guided-fractionation approach was conducted to isolate and identify the active cytotoxic principles. Further chromatographic separation and purification of the petroleum ether extract resulted in the isolation of two anthraquinones identified as aloe-emodin acetate and aloe-emodin, along with stigmasterol, β-sitosterol and palmitic acid. The structure elucidation of isolated compounds was performend using 1D, 2D-NMR and HR-MS. Furthermore, the cytotoxicity of aloe-emodin acetate and aloe-emodin were evaluated and resulted with IC50=153.30 and 70.02 μg/ml against HCT-116 and with 93.20 and 53.20 μg/ml against MCF-7, respectively, while against HepG-2 showed no activity. Moreover, the antiviral activity of the two isolated anthraquinones was tested against influenza virus-A, and resulted with IC50=10.23 as well as 2.00 and with CC50=1.32 and 0.47 μg/ml, respectively.

Opis:
Metal-containing drugs have long been used for medicinal purposes in more or less empirical way. The potential of these anticancer agents has only been fully realised and explored since the discovery of the biological activity of cisplatin. Cisplatin and carboplatin have been two of the most successful anti-cancer agents ever developed, and are currently used to treat ovarian, lung and testicular cancers. They share certain side effects, so their clinical use is severely limited by dose-limiting toxicity. Inherent or acquired resistance is a second problem often associated with platinum-based drugs, with further limits of their clinical use. These problems have prompted chemists to employ different strategies in development of the new metal-based anticancer agents with different mechanisms of action. There are various metal complexes still under development and investigation for the future cancer treatment use. In the search for novel bio-organometallic molecules, iron containing anti-tumoral agents are enjoying an increasing interest and appear very promising as the potential drug candidates. Iron, as an essential cofactor in a number of enzymes and physiological processes, may be less toxic than non essential metals, such as platinum. Up to now, some of iron complexes have been tested as cytotoxic agents and found to be endowed with an antitumor activity in several in vitro tests (on cultured cancer cell lines) and few in vivo experiments (e. g. on Ehrlich's ascites carcinoma). Although the precise molecular mechanism is yet to be defined, a number of observations suggest that the reactive oxygen species can play important role in iron-induced cytotoxicty. This review covers some relevant examples of research on the novel iron complexes.

Opis:
Curcumin is reported as an anti proliferative and chemopreventive compound. However, it shows poor water solubility, low bioavailability, and rapid metabolism.. To address these problems, curcumin derivatives substituted with polyether chain were synthesised to improve the hydrophilicity of curcumin and thus its bioavailability. The biological activity of modified curcumin molecules were studied with human normal B-lymphocytes GM 14667 and human leukemia cells HL60 and covered: the denotation of IC50 values for each new compound with use of MTT test and the studies on apoptosis induction observed as morphological changes and the expression of apoptotic proteins, BAX, BCL-2 and survivin with use of Western Blot analysis. All effects were referenced to native curcumin. The derivatives with modified polyether chains number and the position of methoxy- groups were selected for further studies. As was shown, the solubility of the compound does not directly correlate with its cytotoxicity. The maintenance of the methoxy group in the meta position as well as the introduction of hydrophilic polyether chains but not the number of polyether chains may affect the cytotoxic activity of curcumin derivatives against cancer cells. Modifications of the curcumin molecule structure can determine its impact on the profile of pro or anti apoptotic proteins.

In Mexico, Solanum rostratum has been employed for the treatment of several diseases, including uterine cancer. The aim of this study was to evaluate the antioxidant and anti-carcinogenic activity of extracts of Solanum rostratum Dunal on MDA and SiHa cell lines. The methanolic, ethyl acetate, and hexane extracts of the aerial parts of Solanum rostratum were tested for phenols concentration, antioxidant activity, and anti-carcinogenic effect. The leaves extracts showed the highest content of phenols; however the flower-fruits extracts showed higher scavenging activity. On the other hand, ethyl acetate extracts exhibited the highest anti-carcinogenic effect, while methanolic extracts showed the least effect. The results of this work indicated that Solanum rostratum is a promising source of antioxidants, and the extracts exert a dose-dependent anti-carcinogenic effect on both cell lines.

Opis:
The majority of proteins are unable to translocate into the cell interior. Hence for peptide- and protein-based therapeutics a direct intracytoplasmic delivery with the aid of transducing agents is an attractive approach. We wanted to deliver to the cell interior a putatively cytotoxic protein VPg. Protein transduction was achieved in vitro with three different commercial products. However, in our hands, delivery of various control proteins without known deleterious effects, as well as of protein VPg, always induced cell death. Finally, we used a novel transducing peptide Wr-T, which was not toxic to cultured cells, even in a quite large range of concentrations. Most importantly, control protein delivered to cells in culture did not display any toxicity while VPg protein exerted a strong cytotoxic effect. These data show that results obtained with cell-penetrating agents should be interpreted with caution.

As a part of our ongoing collaborative effort to discover the anticancer activity of the phenolics isolated from terrestrial plant sources, the EtOH extract of the aerial parts of the Egyptian medicinal plant Diplotaxis harra (Forsk.) Boiss. was in vitro investigated for its cytotoxicity against HCT116, HepG2 and MCF-7 cell lines, and resulted with IC50=4.65, 12.60 and 17.90 μg/ml, respectively. Doxorubicin (+ve control) showed in vitro cytotoxic activity with IC50=3.64, 4.57 and 2.97 μg/ml, respectively. The phenolic-rich fraction of the EtOH extract was subjected to further fractionation, which led to the isolation of five flavonoids identified as quercetin, quercetin 3-O-β-glucoside, isorhamnetin 7-O-β-glucoside, apigenin 3-O-β-rhamnoside and kaempferol 3-O-β-glucoside, according to its’ spectral data and comparison with the literature. Furthermore, the isolated flavonoids showed in vitro cytotoxicity against HCT116 cell line with IC50=20.1, 24.3, 22.8, 23.4 and 41.9 μg/ml as determined by MTT method.

Macroalgae from Fucus genus are a valuable source of bioactive components as they are abundant in complex polysaccharides, fatty acids and polyphenols. In this work, the biological activity and chemical composition of extracts and fractions obtained from endemic Fucus virsoides J. Agardh species collected in the summer and in the fall were investigated. From dichloromethane:methanol (1:1) extract three fractions were made: petroleum-ether, ethyl-acetate and n-butanol. The aim of the study was to examine the influence of the seasonal variations on algal composition and activity. The significant seasonal variation in content and biological activity of Fucus virsoides samples was found. Fall extract and fractions exerted higher cytotoxic effects on cancer cell lines in comparison with summer extract and fractions. The examined extracts and fractions showed higher cytotoxic activity towards cancer cells compared to normal fibroblast MRC5 cells. Morphological evaluation and cell cycle distribution analysis demonstrated their proapoptotic activity in human cervical adenocarcinoma HeLa cells. Fall extract and fractions better suppressed the migration and tube formation of EA.hy926 cells in comparison with summer extract and fractions. Fall extract and fractions were more potent in inhibition of α-glucosidase enzymatic activity. Ethyl-acetate fractions, from both seasons, exhibited the best antibacterial and antifungal activity on all tested bacteria and fungi. In conclusion, the two fall fractions ethyl-acetate and petroleum-ether rich in polyphenols and polyunsaturated fatty acids, were the most active and exhibited prominent anticancer and anti-α-glucosidase activities.

Opis:
Cytotoxic activity is one of the major functions of Natural Killer (NK) cells and is a critical effector mechanism of innate immune responses against infected or cancer cells. A variety of assays have been developed to determine NK cell cytotoxic activity, however a receptor-based screening tool is still lacking. Here, we propose the CD25 receptor as a candidate for NK cell cytotoxicity marker. We have verified that there is a correlation between classic target cell induced cytotoxicity markers and the CD25 expression on NK cells. Non-adherent lymphocyte fractions pre-stimulated with Escherichia coli O55:B5 lipopolysaccharide were co-cultured with settled HeLa targets in a four hour long cytotoxic assay. The cytotoxic effect was evaluated by MTT reduction assay and quantification of soluble cytotoxicity markers (granzyme B, FasL, caspase-8, IFN-γ and IL-2) was done by ELISA. Lymphocytes were stained with anti-CD3-Cy-5, anti-CD56/CD16/Nkp46-FITC and anti-CD25-PE antibodies and analyzed by flow cytometry. We observed that the CD25 expression exclusively on the CD3-CD56+CD25+ NK cells was positively correlated with their cytotoxic function evaluated by the MTT test (r = 0.68), the upregulation of granzyme B (r = 0.89), IL-2 (r = 0.78) and IFN-γ (r = 0.57), however, it was not positively correlated with FasL and caspase-8. We conclude that the CD25 expression might serve as an in vitro receptor-based screening tool for NK cell activity.

The methanol extract of the aerial parts of Celosia trigyna (Amaranthaceae) was successively fractionated using n-hexane, dichloromethane, ethyl acetate and n-butanol. The cytotoxic activity of the obtained fractions was investigated using sulphorhodamine-B (SRB) assay against three carcinoma cell lines; breast adenocarcinoma (MCF-7), colorectal carcinoma (HCT-116) and hepatocellular carcinoma cells (HepG2). The dichloromethane fraction showed significant in vitro cytotoxic activities against the human cancer cell lines HCT-116 and HEP-G2 with IC50 values of 10.9 and 11.2 µg/mL, respectively, while all fractions revealed weak antioxidant activity using DPPH free radical scavenging method. The GC-MS analysis of the most cytotoxic dichloromethane fraction has resulted in the identification of 12 compounds. The main constituents were tetrahydroisoquinoline derivative (31.44%), 2,3-dimethylheptadecane (16.71%) and 3-octadecanone (15.56%). Moreover, the phytochemical study of the dichloromethane and n-butanol fractions led to the isolation and identification of five known compounds identified as β-amyrin acetate (1), acacetin 8-C-α-rhamnosyl-(1→2)-β-glucopyranoside (2), apigenin 8-C-α-rhamnosyl-(1→2)-β-glucopyranoside (3), quercetin 3-O-α-rhamnosyl-(1→6)-β-glucopyranoside (4) and 3-hydroxyglutaric acid (5).
