The potential of using tissue culture technique for the production of some bioactive compounds since it allows the manipulation of the biosynthetic routes to increase the production and accumulation of specific compounds. This study was conducted to investigate the effect of vitamins (pyridoxine and nicotinic acid), thiamine-Hcl at different cocentrations (0.5, 1.0 & 2.0 mg/l) and myo-inositol at different concentrations (25, 50, and 100mg/l) at different cocentrations supplemented in MS basal nutrient medium of embryogenic callus of date palm on the production of secondary metabolites of amino acids and indoles. Tow egyption cultivars (Sakkoty and Bartamuda cultivars) of date palm were used. Pyridoxine concentration at 0.5mg/l was the most effective concentration in the production of amino acids and indoles from embryonic callus of the tow studied cultivars of date palm. Nicotinic acid at 0.5mg/l showed also the best results of production of amino acids and indoles from embryogenic callus of two cultivars. Acording to thiamine at 2mg/l concentration was the most effective in inducing the highest significant value of amino acids and indoles from embryonic callus of two cultivars of date palm. Myo-inositol concentration at 25mg/l produced the highest significant value of amino acids and indoles.

Now introduce a scientific discovery about this category.

The effect of indole-3-carbinol on the proliferation and migration of MDA-MB-231 breast-cancer cells and healthy MCF-10A breast-tissue cells has been studied. It was shown that indole-3-carbinol reliably reduced the proliferation and migration of MDA-MB-231 cells and does not significantly affect MCF-10A cells. The incubation of MDA-MB-231 tumor cells with 100 mu M indole-3-carbinol for 48 h resulted in a marked decrease in the expression of the Wnt cascade genes CCND1 (by 28%), Sp1 (by 44%), CDK6 (by 47%), as well as the EGFR and FASN genes (by 64 and 22%, respectively). Incubation of the MCF-10A cell line under the same conditions induced a noticeable decrease in the expression of only two genes, EGFR (by 16%) and CDK6 (by 9%). Indole-3-carbinol was also shown to display selective DNA demethylating activity in breast-tumor cells and to reverse the process of abnormal methylation and functional blockage of the antitumor WIF-1 gene. The obtained data indicate that drugs containing indole-3-carbinol as an active component can be potential regulators of epigenetic processes in the complex treatment of breast cancer and other tumors.

To discover novel anticancer agents with potent and low toxicity, we designed and synthesized a range of new thiosemicarbazone-indole analogues based on lead compound 4 we reported previously. Most compounds displayed moderate to high anticancer activities against five tested tumor cells (PC3, EC109, DU-145, MGC803, MCF-7). Specifically, the represented compound 16f possessed strong antiproliferative potency and high selectivity toward PC3 cells with the IC50 value of 0.054 mu M, compared with normal WPMY-1 cells with the IC50 value of 19.470 mu M. Preliminary mechanism research indicated that compound 16f could significantly suppress prostate cancer cells (PC3, DU-145) growth and colony formation in a dose-dependent manner. Besides, derivative 16f induced G1/S cycle arrest and apoptosis, which may be related to ROS accumulation due to the activation of MAPK signaling pathway. Furthermore, molecule 16f could effectively inhibit tumor growth through a xenograft model bearing PC3 cells and had no evident toxicity in vivo. Overall, based on the biological activity evaluation, analogue 16f can be viewed as a potential lead compound for further development of novel anti-prostate cancer drug. (C) 2020 Elsevier Masson SAS.

Nudicaulins are yellow flower pigments accounting for the color of the petals of Papaver nudicaule (Papaveraceae). These glucosidic compounds belong to the small group of indole/flavonoid hybrid alkaloids. Here we describe in vivo and in vitro experiments which substantiate the strongly pH-dependent conversion of pelargonidin glucosides to nudicaulins as the final biosynthetic step of these alkaloids. Furthermore, we report the first synthesis of nudicaulin aglycon derivatives, starting with quercetin and ending up at the biomimetic fusion of a permethylated anthocyanidin with indole. A small library of nudicaulin derivatives with differently substituted indole units was prepared, and the antimicrobial, antiproliferative and cell toxicity data of the new compounds were determined. The synthetic procedure is considered suitable for preparing nudicaulin derivatives which are structurally modified in the indole and/or the polyphenolic part of the molecule and may have optimized pharmacological activities.

As an interspecies and interkingdom signaling molecule, indole has recently received attention for its diverse effects on the physiology of both bacteria and hosts. In this study, indole increased the tetracycline resistance of Vibrio splendidus. The minimal inhibitory concentration of tetracycline was 10 mu g/mL, and the OD600 of V. splendidus decreased by 94.5% in the presence of 20 mu g/mL tetracycline; however, the OD600 of V. splendidus with a mixture of 20 mu g/mL tetracycline and 125 mu M indole was 10- or 4.5-fold higher than that with only 20 mu g/mL tetracycline at different time points. The percentage of cells resistant to 10 mu g/mL tetracycline was 600-fold higher in the culture with an OD600 of approximately 2.0 (higher level of indole) than that in the culture with an OD600 of 0.5, which also meant that the level of indole was correlated to the tetracycline resistance of V. splendidus. Furthermore, one differentially expressed protein, which was identified as the outer membrane porin OmpN using SDS-PAGE combined with MALDI-TOF/TOF MS, was upregulated. Consequently, the expression of the ompN gene in the presence of either tetracycline or indole and simultaneously in the presence of indole and tetracycline was upregulated by 1.8-, 2.54-, and 6.01-fold, respectively, compared to the control samples. The combined results demonstrated that indole enhanced the tetracycline resistance of V. splendidus, and this resistance was probably due to upregulation of the outer membrane porin OmpN.
