Efficient hydrogenation of electron-deficient internal olefins and alkynes access to saturate ketone with CH3OH as a single hydrogen donor under electrochemical conditions has been successfully developed. This hydrogenation strategy can be used to convert electron-deficient internal olefins and alkynes to saturate ketone under electrochemical conditions with exogenous-reductant and a metal catalyst. Mechanistic studies reveal that radical hydrogenation was involved in this transformation. Notably, various electron-deficient internal olefins and alkynes could be tolerated in such an electrochemical hydrogenation synthetic strategy and can be easily scaled up with good efficiency.

The chalcone derivatives 3a-d reacted with either malononitrile or ethyl cyanoacetate in ethanol in the presence of catalytic amount of ammonium acetate in an oil bath at 120 degrees C to give the Knowevenagel condensation products 5a-h. The latter compounds reacted with hydrazine hydrate and afforded the 4H-pyrazole derivatives 7a-h, respectively. The reaction of compounds 7a-h with ethyl cyanoacetate in dimethylformamide under refluxing condition afforded the cyanoacetamido derivatives 8a-h, respectively. When compounds 8a-h reacted with elemental sulfur and either of malononitrile or ethyl cyanoacetate in ethanol containing triethylamine, the thiophene derivatives 9a-h and 10a-h, respectively, were obtained. The structure of the newly synthesized compounds was established by the analytical and spectral data. All the newly synthesized compounds were evaluated against the six cancer cell lines: A549, HT-29, MKN-45, U87MG, and SMMC-7721 and H460. Compounds 3c, 5h, 7g, 7h, 8f, 9e, 9g, and 10g were selected to examine their Pim-1 kinase inhibition activity as these compounds showed high inhibition toward the c-Met kinase and the tested cancer cell lines. Furthermore, compounds 3b, 3c, 5g, 5h, 7f, 7g, 7h, 8e, 8f, 8g, 8h, 9e, 9f, 9g, 9h, 10g and 10h were selected to be tested for pan-assay interference compounds analysis (PAINS). Almost all the tested compounds showed zero PAINS alert and can be used as drug compounds in the future.

Chalcones, as a large group of organic compounds, are widely implemented in various types of anticancer therapeutics. These plant metabolites are present in fruits, vegetables, spices, and have anti-tumor, anti-inflammation, immunomodulation, antibacterial and anti-oxidative activities, as well as many other pharmacological and biological effects. The aim of the present study was to investigate cytotoxic effects, type of cell death and mechanism of action of the newly synthesized vanillin based chalcone analogs, (CH1) and (CH2) on human colon cancer HCT-116 and noncancerous (control) MRC-5 cell lines. In order to compare the effects of vanillin based chalcone analogs on investigated cell lines, as reference substances cisplatin (cisPt) and dehydrozingerone (DHZ) were used. Investigation of antitumor effect of chalcone analogs on HCT-116 cells was carried out by three methods MTT assay, flow cytometry and immunofluorescence analysis. The result of our investigation indicated that newly synthesized vanillin based chalcone analogs expressed powerful antitumor effect on cancer cells (HCT-116 cell line), while their effect on healthy cells (MRC-5 cell line) was not statistically significant. Vanillin based chalcone analogs caused overexpression and activation of mitochondrial Bax protein and caspase-3 in HCT-116 cells, indicating that their mechanism of antitumor action was mediated through activation of the inner apoptotic pathway. These results indicate possible usefulness of CH1 and CH2 in antitumor therapy whether through its direct cytotoxic effect or as adjuvant therapy. Our results indicate possible usefulness of CH1 and CH2 vanillin based chalcone analogs in antitumor therapy.

An article Abscisic acid and stress induced by salt: Effect on the phenylpropanoid, L-ascorbic acid and abscisic acid metabolism of strawberry fruits WOS:000536123200021 published article about FRAGARIA-X-ANANASSA; PHENYLALANINE AMMONIA-LYASE; TIME-QUANTITATIVE PCR; DIFFERENT CULTIVARS; GENE-EXPRESSION; DROUGHT STRESS; TOLERANCE; PROLINE; PLANT; MECHANISMS in [Crizel, R.

Strawberry is one of the most popular fruits because of its sensorial and functional properties. However, strawberry crop is sensitive to salt stress conditions. Despite plants have plasticity, high salt concentrations induce molecular, biochemical, and physiological responses in plants. There is evidence that the abscisic acid (ABA) hormone acts as a signaling molecule under stress conditions; however, the molecular mechanisms involved in the synthesis and homeostasis of ABA and in the induction of phytochemical antioxidant compounds under stress conditions remain unclear. In this study, the effect of stress induced by NaCl (salt stress – SS), with or without the simultaneous application of ABA, on the ABA, phenylpropanoids and L-ascorbic acid (AsA) metabolisms were evaluated. The physiological aspects (Na, Cl and proline concentration, photosynthetic variables) were also studied. The results showed that salt stress increases the Na and Cl content in the leaves, affects photosynthetic variables and triggers the production of proline, pelargonidin-3-O-glucoside, total phenolic compounds and AsA content, alongside the upregulation of several genes from the phenylpropanoid and flavonoid pathways. These effects were accompanied by the induction of compounds and transcripts related to ABA biosynthesis, conjugation and catabolism. Otherwise, the exogenous application of ABA in salt stressed plants promotes a shift in gene expression and metabolism to mitigate the stress. Therefore, salt stress affects the metabolism of ABA, phenylpropanoids and AsA in strawberry increasing phytochemical composition which is strongly associated with an ABA-dependent mechanism.

The resistance of tumors against anticancer drugs is a major impediment for chemotherapy. Tumors often develop multidrug resistance as a result of the cellular efflux of chemotherapeutic agents by ABC transporters such as P-glycoprotein (ABCB1/P-gp), Multidrug Resistance Protein 1 (ABCC1/MRP1), or Breast Cancer Resistance Protein (ABCG2/BCRP). By screening a chemolibrary comprising 140 compounds, we identified a set of naturally occurring aurones inducing higher cytotoxicity against P-gp-overexpressing multidrug-resistant (MDR) cells versus sensitive (parental, non-P-gp-overexpressing) cells. Follow-up studies conducted with the P-gp inhibitor tariquidar indicated that the MDR-selective toxicity of azaaurones is not mediated by P-gp. Azaaurone analogs possessing pronounced effects were then designed and synthesized. The knowledge gained from structure-activity relationships will pave the way for the design of a new class of anticancer drugs selectively targeting multidrug-resistant cancer cells.
