In an attempt to discover new potent inhibitors for Mycobacterium tuberculosis (Mtb), a series of 2-(2-hydrazinyl)thiazole derivatives with a wide range of substitutions at 2-, 4- and 5-positions were designed by considering Lipinski rule. The designed compounds were synthesized, characterized a...

Static magnetic field (SMF) has been known to affect cell proliferation in a cell-type-dependent manner, while the mechanism still remains unclear. We found that 1 T moderate intensity SMF inhibits cell proliferation of nasopharyngeal carcinoma CNE-2Z cells and the Akt/mTOR signaling pathway, wh...

The palladium-catalyzed one-pot sequential reaction of propiolic acid derivatives with lithium halides first, and then with terminal alkynes or alkenes affords conjugated (2Z) -en-4-ynoic and (2Z,4Z)- and (2Z,4E)- dienoic acid derivatives with high stereoselectivity.
