We have previously described the synthesis and evaluation of 3,5-diamino-1,2,4-triazole analogues as inhibitors of the flavin-dependent histone demethylase LSD1. These compounds are potent inhibitors of LSD1 without activity against monoamine oxidases A and B, and promote the elevation of H3K4me2 levels in tumor cells in vitro. We now report that the cytotoxicity of these analogues in pancreatic tumor cells correlates with the overexpression of LSD1 in each tumor type. In addition, we show that a subset of these 3,5-diamino-1,2,4-triazole analogues inhibit a related flavin-dependent oxidase, the polyamine catabolic enzyme spermine oxidase (SMOX) in vitro.

Herein, we describe the design, synthesis and optoelectronic characterization of a new series of highly fluorescent dyes configured with a D-A-D ‘ architecture, viz. CP1 to CP7. In the new molecular design, various electron-donating scaffolds were integrated with an efficient electron-accepting trialkoxyphenyl-substituted cyanopyridone moiety to study the effect of donor strength on their thermal and opto-physical properties. A detailed investigation of their thermal properties reveals that they are thermally robust with high melting and decomposition temperatures. Furthermore, in-depth photophysical studies expose their remarkable fluorescence ability in both solution and aggregated state within a wide spectral range from blue to orange. Evidently, among all the fluorophores, dyads bearing amino donors were found to be highly intense emitters due to their superior donating strength. Furthermore, solvatochromic studies showcase their ICT-dominated optoelectronic properties and it was confirmed by different correlation studies. Finally, the experimental results were correlated with their quantum chemical simulation data.

A biocatalytic cascade process was developed using immobilized cells of the wild type yeast Candida albicans CCT 0776 in calcium alginate beads and a commercially available ketoreductase. The aim was to promote deracemization by stereoinversion of (+/-)-1-arylethanols in high substrate concentration (above 100 mmol L-1) to prepare the (R)-enantiomers of the alcohols (90-99%). with a high enantiomeric excess (83-99%) after 2 to 19 h. The (R)-1-(3-methoxyphenyl)ethanol, with 70% yield and 91% ee, obtained after 5 h was used to prepare (S)-1-(3-methoxyphenyl)-ethylamine with 60% yield and 91% ee after two steps. a key intermediate in the synthesis of (S)-rivastigmine.

A thorough study of mild and environmentally friendly electrochemical-induced hydroxylation of aryl halides without a catalyst is presented. The best protocol consists of hydroxylation of different aryl iodides and aryl bromides by water solution in the presence of Et3N under air, affording the target phenols in good isolated yields. Moreover, aryl chlorides were successfully employed as substrates. This methodology also provides a direct pathway for the formation of deoxyphomalone, which displayed a significant anti-proliferation effect.

A single C-2-symmetric squaramide catalyst system allows the facile addition of either malononitrile or benzyl nitroacetate to simple pyrazole-based Michael acceptors with excellent enantiocontrol and at lower catalyst loadings than previously possible. The latter reactions are not diastereoselective, however facile hydrogenolysis leads to decarboxylation and formation of the formal adduct from the addition of nitromethane (a very recalcitrant nucleophile in this chemistry) with excellent yield and enantiocontrol.

An article Catalytic oxidation of alcohols using Fe-bTAML and NaClO: Comparing the reactivity of Fe(V)O and Fe(IV)O intermediates WOS:000454151300059 published article about H BOND OXIDATION; C-H; AEROBIC OXIDATION; SECONDARY ALCOHOLS; HYDROGEN-PEROXIDE; IRON COMPLEXES; MECHANISM; FE-V(O); NANOPARTICLES; ACTIVATION in [Jana, Sandipan; Thomas, Jithin; Sen Gupta, Sayam] IISER, Dept Chem Sci, Kolkata 741246, Mohanpur, India in 2019.0, Cited 64.0.

We demonstrate the selective oxidation of secondary alcohols and activated primary alcohols to their corresponding aldehydes or ketones using Fe-bTAML as the catalyst and sodium hypochlorite (NaClO) as the oxidant. Good to excellent yields of 80%-99% for the carbonyl compounds and turnover numbers up to similar to 500 was obtained with this catalytic system. The reactions are clean, performed under mild conditions (air, room temperature) and yielded sodium chloride as the only by-product. The yield and turnover number were dependent on the pH of the reaction and this difference was attributed to the different reactive intermediates that was formed at pH 7 and pH 12 (Fe-V(O) and Fe-IV(O) respectively). Reactions involving the Fe-V(O) intermediate oxidize secondary alcohols more efficiently than its Fe-IV(O) analog. This trend was reversed for the oxidation of activated primary alcohols where reactions involving Fe-IV(O) afforded much higher TON’s. This reactivity trend can be explained from the differences in bond dissociation energy (BDE) of their corresponding one electron reduced species ([Fe-IV-OH], similar to 99 kcal/mol; [Fe-III-OH], similar to 83 kcal/mol) as well as their relative stabilities in the solvent during reaction. This catalytic system was found to be unsuitable for nonconjugated primary alcohol due to the formation of the inactive Fe-IV(OMe) intermediate after one catalytic cycle.

New ecofriendly Biginelli reaction procedures have been adapted to prepare new dihydropyrimidines (DHPMs) using a multicomponent one-pot reaction. All the synthesized compounds were evaluated for their anticancer activity against 59 human cancer cell lines and evaluated for their antimicrobial activities against representatives of both Gram-positive and Gram-negative bacteria. Compound 4 showed marked wide spectrum anticancer activity towards most of the tested cancer cell lines with a percentage of growth inhibition of 29.04-71.68% against leukemia cell line (K-562 and SR), lung cancer cell line (NCI-H522), five colon cancer cell lines (HCT-116, HCT-15, HT29, KM12 and SW-620), CNS cancer cell line (SF-295 and SNB-75), melanoma cell lines (MALME-3M and M14), renal cancer cell line (CAKI-1) and breast cancer cell lines (MCF7 and MDA-MB-468). The highest observed anticancer activity was against leukemia cell lines K-562 and SR with inhibition percentages of 64.97 and 71.68%, respectively. The renal cancer cell line (UO-31) was particularly sensitive towards all the evaluated compounds. Compounds including 2b and 5c exhibited antibacterial activity against S. aureus while 2a and 5b exhibited antifungal activity against C. albicans. The results also showed that compounds 2c and 5e exhibited both antibacterial and antifungal activity against S. aureus and C. albicans respectively.

A regioselective C-H functionalization/annulation reaction of N-sulfonyl amides and allylbenzenes through a palladium-catalyzed C(sp(2))-H allylation/aminopalladation/beta-H elimination/isomerization sequence has been reported. Various aryl and alkenyl carboxamides are found to be efficient substrates to construct isoquinolinones and pyridinones in up to 96% yield. Using ambient air as the terminal oxidant is another advantage regarding environmental friendliness and operational simplicity.
