Opis:
Grzyby z gromady Basidiomycota od dawna budzą zainteresowanie ze względu na występowanie w ich owocnikach szeregu związków o uznanych właściwościach leczniczych. Obiektem przeprowadzonych badań były kultury mycelialne dwóch gatunków grzybów afylloforoidalnych występujących na terenie Polski Hydnum repandum L. oraz Sparassis crispa (Wulf.) Fr. Celem podjętych badań była jakościowa i ilościowa analiza ekstraktów otrzymanych z kultur mycelialnych pod kątem występowania związków o udokumentowanej aktywności biologicznej: kwasów fenolowych, niehalucynogennych związków indolowych oraz steroli. Do oznaczeń wykorzystano wysokosprawną chromatografię cieczową faz odwróconych (RP-HPLC). Na podstawie analizy stwierdzono w ekstraktach z otrzymanej biomasy obecność ośmiu kwasów fenolowych: galusowego, gentyzynowego, p-hydroksybenzoesowego, kawowego, kumarowego, protokatechowego, syryngowego, wanilinowego oraz kwasu cynamonowego. Ilościowo dominującym związkiem był kwas protokatechowy w ilości 6,23 μg/g s.m. (H. repandum) oraz kwas hydroksybenzoesowy w ilości 4,52 μg/g s.m. (S. crispa). Spośród związków pochodnych indolu ilościowo oznaczono: indol, serotoninę, tryptaminę i tryptofan. Całkowita ich zawartość wynosiła 1,28 μg/g s. m. (ekstrakty z H. repandum) oraz 3,07 μg/g s.m. (ekstrakty z S.crispa). Ilościowo dominującym metabolitem był tryptofan. Spośród steroli oznaczono ergosterol w biomasie z kultur in vitro S. crispa (700,87 μg/g s.m). Uzyskane wyniki wskazują, że przebadane kultury mycelialne krajowych gatunków grzybów afylloforoidalnych są zdolne do akumulacji metabolitów aktywnych biologicznie.  
For a long time fungi belonging to Basidiomycota phylum have been in the center of attention because of the presence in their fruiting bodies of compounds with known therapeutic activity. Mycelial cultures of two aphyllophorales species occurring in Poland, Hydnum repandum L., and Sparassis crispa (Wulf.) Fr., were analyzed in our study. The main aim of the study was qualitative and quantitative analysis of extracts obtained from the mycelial cultures for the presence of known biologically active compounds, including phenolic acids, non-hallucinogenic indole compounds and sterols. For analyses a reversed-phase chromatography (RP-HPLC) method was used. The presence of eight phenolic acids including gallic, gentisic, p-hydroxybenzoic, caffeic, p-coumaric protocatechuic, syringic, vanillic and cinnamic acids was confirmed in the extracts obtained from the biomass. The quantitatively predominant metabolites in biomass from in vitro cultures of H. repandum and S. crispa were protocatechuic acid (6.23 μg/g DW) and p-hydroxybenzoic acid (4.52 μg/g DW). Derivatives of indole such as indole, serotonin, tryptamine and tryptophan were measured quantitatively. Their total content was estimated as 1.28 μg/g DW and 3.07 μg/g DW in H. repandum and S. crispa extracts, respectively. The major metabolite found was tryptophan. In addition, ergosterol, one of the sterols present in the biomass of in vitro cultures of S. crispa was analyzed (700.87 μg/g DW). The obtained results confirm the hypothesis that mycelial cultures of domestic species of aphyllophorales are able to accumulate biologically active metabolites.

Opis:
Isatins are synthetically versatile substrates, where they can be used for the synthesis of a large variety of heterocyclic compounds. In this, a convenient method has been developed for the conversion of Indoles into Isatins and some heterocyclic derivative were synthesised such as 5- nitro-1H-indole-2,3-dione, 2-methylquinoline-4-carboxylic acid which may be used as raw material for drug synthesis. The general process utilizes the effective method for synthesis of Isatin from Indole is bromination and oxidation with an N-bromosuccinimide-dimethyl sulfoxide reagent. The nitration of Isatin at C-5 takes place by using KNO3, conc. H2SO4, 2-methylquinoline-4-caboxylic acid are usually obtained from pfitzinger reaction.

Opis:
Developing catalyst is very significant for biologically important reactions which yield products, used as drugs. Mechanistic study on meso-tetraphenylporphyriniron(III) chloride (TPP) catalysed oxidation of indole by sodium perborate in aqueous acetic acid medium have been carried out. The reaction follows a fractional order with respect to substrate and catalyst. The order with respect to oxidant was found to be one. Increase in the percentage of acetic acid and increase in the concentration of [H+] decreased the rate. The reaction fails to initiate polymerization, and a radical mechanism is ruled out. Activation and thermodynamic parameters have been computed. A suitable kinetic scheme based on these observations has been proposed. Significant catalytic activity is observed for the reaction system in the presence of TPP.

Opis:
The effects of the phytohormone indole-3-acetic acid and various conditions of illumination on the growth of Parachlorella kessleri were investigated. Two variants of illumination: continuous and photoperiod 16/8 h (light/dark) and two concentrations of the phytohormone – 10-4 M and 10-5 M of indole-3-acetic acid were used in the experiment. The results of this study show that the addition of the higher concentration of indole-3-acetic acid stimulated the growth of P. kessleri more efficiently than the addition of the lower concentration of indole-3-acetic acid. This dependence can be observed in both variants of illumination. Increased biomass productivity was observed in the photo-period conditions. Both the addition of the phytohormone and the conditions of the illumination had an impact on the number of P. kessleri cells. An increased number of cells was observed under the conditions of continuous illumination. This result has shown that the continuous illumination and the higher concentration of the phytohormone stimulated the growth of P. kessleri more effectively than the shorter duration of light (16/8 h (light/dark)).

Opis:
Based on overlapping structural requirements for both efficient aldose reductase inhibitors and PPAR ligands, [5-(benzyloxy)-1H-indol-1-yl]acetic acid (compound 1) was assessed for inhibition of aldose reductase and ability to interfere with PPARγ. Aldose reductase inhibition by 1 was characterized by IC50 in submicromolar and low micromolar range, for rat and human enzyme, respectively. Selectivity in relation to the closely related rat kidney aldehyde reductase was characterized by approx. factor 50. At organ level in isolated rat lenses, compound 1 significantly inhibited accumulation of sorbitol in a concentration-dependent manner. To identify crucial interactions within the enzyme binding site, molecular docking simulations were performed. Based on luciferase reporter assays, compound 1 was found to act as a ligand for PPARγ, yet with rather low activity. On balance, compound 1 is suggested as a promising lead-like scaffold for agents with the potential to interfere with multiple targets in diabetes.

Opis:
Mushrooms are able to accumulate both primary and secondary metabolites. Medicinal and antioxidant properties of mushrooms are an excellent combination of their nutrition value. Recent studies have demonstrated that edible mushroom species contain non–hallucinogenic indole compounds and their derivatives. The indole skeleton is the basis of the substances serving important functions in the human body, such as serotonin and melatonin. These compounds fulfill the role of neurotransmitters or their precursors, exhibit antioxidant, anticancer, anti–aging actions, regulate the diurnal cycle in humans and participate in blood coagulation. These compounds and their derivatives are also anti– inflammatory and analgesic therapeutics.

Opis:
A modular three step synthetic approach of N-methyl indole derivatives has been carried out by the condensation of N-methyl indole with cyanoacetic acid using acetic anhydride as solvent to yield 3-cyanoacetyl N-methyl indole, which further reacts with carbon disulphide and methyl iodide in basic condition to obtain 2-(1-methyl-1H-indole-3-carbonyl)-3,3-bis(methylthio)acrylonitrile as a scaffold. Subsequent, the scaffold when reacts with substituted various amine derivatives via desulfitative displacement forms new derivatives of 3-((substitutedphenyl)amino)-2-(1-methyl-1H-indole-3-carbonyl)-3-(methylthio)acrylonitrile in moderate to good yields. All the novel compounds were evaluated for their antimicrobial activity against Gram+ve and Gram-ve bacteria and different fungal species which demonstrated well to moderate antimicrobial activity.

Arthrospira platensis (Spirulina platensis) is a well-known microalga and has been utilized as a medicinal agent and foodstuff by humans since at least 16th century. The aim of this study was to determine zinc content as well as determine phenolic and indole compounds from commercial preparations containing Arthrospira platensis (lyophilizate, tablets, and capsules) before and after extraction with methanol and incubation with artificial digestive juices. The secondary aim of this study was to evaluate the quality of these preparations. The samples were incubated in artificial stomach juice and in intestinal juice. The samples were mineralized and their zinc(II) ions content was estimated using flame absorption atomic spectroscopy (F-AAS). The maximum zinc(II) ions content released into the digestive juices was found to be up to 1.6 mg 100 g-1 of the preparation. Phenolic compounds identified in the examined extracts are as follows: gallic acid; protocatechuic acid; 3,4-dihydroxyphenylacetic acid; p-hydroxybenzoic acid; syringe acid; cinnamic acid; and quercetin. Furthermore, indole compounds identified were 5-hydroxy-L-tryptophan, 5-methyl-L-tryptophan, L-tryptophan, tryptamine, and 5-methyltryptamine. Consequently, it was also found that the distributed Arthrospira platensis in the form of tablets does not disintegrate in the artificial digestive juices. Among the examined preparations, only hard capsules met the requirements of the European Pharmacopeia 8th ed.

In the present study, the effects of 10, 20, 30 ppm hormone mixtures (indole-3-acetic acid + + gibberellic acid + kinetin) with 0.1, 0.3, 0.5 and 1 ppm zinc (Zn) concentrations alone and their mixtures on the cambial activity of sour cherry (Cerasus vulgaris Miller) cuttings were investigated. Morphological and anatomical developments of the plants were observed. The leaves of the plants treated with zinc were found to be greener than the control. Plants treated with zinc faded earlier than the control. The cambial zone thickness, the cambial zone cell line, the radial and tangential lengths of the cambial zone cells decreased with increasing concentrations of zinc and increased with increasing concentrations of hormones. The radial and tangential wall widths of the cambial zone cells increased with increasing zinc concentrations and decreased with increasing hormone concentrations. As a result, in the 0.1, 0.3, 0.5 and 1 ppm Zn concentrations, the cambial zone thickness decreased by 10, 28, 50 and 65%, respectively, compared to the control. Thirty ppm hormone mixture – H.M. (indole-3-acetic acid + gibberellic acid + kinetin) increased the cambial zone thickness by 65, 15, 5% in 0.1, 0.3 and 0.5 Zn, respectively, compared to the control. It was found that plant hormones importantly improved the harmful effects of zinc on the cambial activity of the plant cuttings.

Opis:
The research goals of presented work consisted of determination of zinc and indole compounds that are released into artificial digestive juices from Tricholoma equestre species. During the experiment freeze-dried samples of wild growing fruiting bodies and mycelia from in vitro cultures from liquid Oddoux medium were extracted to artificial digestive juices (saliva, gastric juice and intestinal juice). In the next step the determination of examined compounds was done by RP-HPLC for indole compounds and DP ASV for zinc. Furthermore it was decided to check weather this species has any beneficial properties for health. The extraction of researched material in conditions imitating human digestive tract allows determination of true amounts of elements released to artificial digestive juices and their beneficial influence (a specially designed and constructed apparatus Gastroel-2014 was applied). The indole compound with the highest quantity was 5-hydroxy-L-tryptophan, both in fruiting bodies and in biomass from in vitro cultures of T. equestre (up to 352.47 mg/100 g d.w.). Serotonin and L-tryptophan was determined in all analysed samples, but their amounts were significantly lower than the ones found for 5-hydroxy-L-tryptophan. The amounts of zinc on the other hand showed that the biggest concentration of zinc can be obtained for fruiting bodies and biomass from in vitro cultures to both artificial saliva and gastric juice after 120 minutes of digestion (6.83 14.4 mg/100 g d.w. retrospectively) in conditions that imitate human digestive track.

Opis:
Aloe vera [Aloe vera (L.) Burm. f.] is considered a valuable medicinal plant worldwide due to its remarkable beneficial effects on human health. However, challenges in A. vera propagation hinder meeting the increasing demand in the health and beauty sectors. As an alternative method, in vitro propagation is crucial for the mass production of Aloe plants, which is a rapid method as well. Therefore, the present study aimed to establish an efficient micropropagation protocol for A. vera by in vitro optimization of the effect of different plant growth regulators (PGRs). For shoot proliferation, sterilized explants were inoculated on the Murashige and Skoog (MS) medium supplemented with 6-benzylaminopurine (BAP) and thidiazuron (0.5, 1.0, 2.0, and 4.0 mg/l) in combination with 0.5 mg/l naphthaleneacetic acid (NAA). Subsequently, indole-3-butyric acid (IBA) (1.0, 2.0, and 3.0 mg/l) was used for root induction. It was found that the explants cultured on the MS medium supplemented with 4.0 mg/l BAP + 0.5 mg/l NAA showed the highest percentage of response (90 ± 1.29) for shoot induction within the minimum number of days (5 ± 0.33). The highest number of shoots (2.7 ± 0.36) and length of shoots (4.7 ± 0.42 cm) per explant were also observed with the same concentration of PGRs. However, the highest number of roots (3.2 ± 0.57), length of roots (5.67 ± 0.21 cm), and root induction (80 ± 1.97 %) were noticed within the minimum number of days (11 ± 0.79) on the MS medium supplemented with 1.0 mg/l IBA. Thus, the proposed method is a quick and effective approach for the mass propagation of A. vera with appropriate dosages of auxins and cytokinins, which may allow meeting the increasing commercial demand.
