Summary: Various functionalized enantiomerically pure 3-hydroxymethyl-1,4-benzoxazine derivatives, including four stereoisomers, were synthesized from chiral 2,3-epoxy-4-trityloxybutanol using a mild and metal-free method. The mechanism was investigated using online Fourier-transform infrared spectroscopy, revealing a base-promoted cyclization to form intermediates followed by a hydrolysis process. The obtained chiral derivatives showed high stereoselectivity and yield, and were easily derivatized to form unique tricycle-fused benzoxazines.

Summary: The reactivity of 1H-benzimidazol-2-ylacetonitrile and 5-amino-2,4-dihydro-3H-pyrazol-3-one towards 3-substituted-6,8-dimethylchromones was studied. Different chemical transformations were used to efficiently synthesize various pyrido[1,2-a]benzimidazoles, chromeno[2,3-b]pyridines, pyrazolo[3,4-b]pyridines and chromenopyrazolopyridines. The molecular geometry, reactivity descriptors, and NMR chemical shift values of the synthesized compounds were determined using density functional theory. The compounds also exhibited promising nonlinear optical properties and in silico ADME calculations were performed.

Summary: A stereo-selective palladium-catalyzed one-pot Tsuji-Trost reaction was used to synthesize four fl-thiogalactosides from unsaturated D-galactal and thiol. The structures were characterized using various analytical techniques, and X-ray crystallography confirmed the absolute configuration of the compounds. The thiogalactosides showed anti-proliferative activities against human gastric cancer cells.

Summary: The present study found that YC-1 can upregulate the expression of CHAC1 in HK-2 cells through the activation of the sGC-cGMP-PKG, Akt-mTOR, and ER stress pathways. The induction of CHAC1 reduced the intracellular glutathione concentration and played an important role in intracellular redox homeostasis in tubular cells.

Summary: A new potent analgesic, (3R,4S)-9d, with low ED50 values in hot plate and antiwrithing models has been identified through phenotypic screening. Mechanistic studies revealed that its analgesic effect is mediated via the active metabolite (3R,4S)-10a, with proposed activation of the mu opioid receptor (MOR) mechanism using molecular dynamics (MD) simulation.

Summary: The synthesis and structure-activity relationships of YC-1 analogs are crucial for exploring special bioactivities, including vasodilation, inhibition of hypoxia-inducible factor, and NF-kappa B activation. Riociguat, derived from YC-1 structure, is the first soluble guanylate cyclase stimulator drug used for treating pulmonary hypertension and pulmonary arterial hypertension.

Summary: In this study, E- and Z-isomers of CITCO were synthesized and characterized to address the stability issues of CITCO. The isomers were found to undergo E/Z isomerizations in solution via a protonation-rotation mechanism, and both stereoisomers were shown to be able to bind to hCAR according to molecular modeling studies.
