An iron‐catalyzed chemo‐ and diastereoselective reduction of α,β‐unsaturated ketones into the corresponding saturated ketones in mild reaction conditions is reported herein. DFT calculations and experimental work underline that transfer hydride reduction is a more facile process than hydrogenation, unveiling the fundamental role of the base.

and thiazole derivatives have many biological functions, especially in the aspect of anti-inflammation. According to the strategy of pharmacophore combination, we introduced thiazole moiety into dihydropyrazole skeleton to design and synthesize a novel series of 2-(3,5-diphenyl-4,5-dihydro-1H-pyrazol-1-yl)-4-methylthiazole derivatives, and evaluated their anti-inflammatoryactivities for sepsis treatment

A series of 3-(substituted aroyl)-4-(3,4,5-trimethoxyphenyl)-1H-pyrrole derivatives were synthesized and determined for their anticancer activity against eleven cancer cell lines and two normal tissue cell lines using MTT assay. Among the synthesized compounds, compound 3f was the most potent compound against A375, CT-26, HeLa, MGC80-3, NCI-H460 and SGC-7901 cells (IC50 = 8.2 - 31.7 μm); 3g, 3n and

A newseries of pyrazoline derivatives 1b-12b was designed, synthesized and evaluated for antiproliferative activity against three cancer cell lines (HepG-2, Hela and A549). Additionally, NIH/3T3 cell cytotoxicity were tested and the structure activity relationships (SARs) were also determined. Among these newderivatives, the compounds 3-(4-fluorophenyl)-5-(3,4,5-trimethoxythiophenyl)-4,5-dihydro

Molecular docking study showed that 20, 22, 24 and 25 had good binding affinity with active site residues via Thr280. DNA macromolecule was further targeted. Compounds 28 and 34 were recorded to have better DNAbinding than doxurubucin with IC50 of 27.48 and 30.97 µg/ml respectively, suggesting that it could have a role in their higher antibacterial effect. Their docking into DNA has shown a clear
