The reaction of N-phenylimidoyl isoselenocyanates 1 with 2-amino-1,3-thiazoles 10 in acetone proceeded smoothly at room temperature to give 4H-1,3-thiazolo[3,2-a] [1,3,5]triazine-4-selones 13 in fair yields (Scheme 2). Under the same conditions, 1 and 2-amino-3-methylpyridine (11) underwent an addition reaction, followed by a spontaneous oxidation, to yield the 3H-4l4-[1,2,4]selenadiazolo[1’,5’...
5H-benzo[h]thiazolo[2,3-b]quinazoline scaffold is known to have an antitumor effect on certain types of malignancies; however, its effect on hepatocellular carcinoma (HCC) remains unclear. Previously, we reported p-toluenesulfonic acid-promoted syntheses, molecular modeling and in vitro antitumor activity of 5H-benzo[h]thiazolo[2,3-b]quinazoline against human hepatoma (Hep-G2) cells where compo...
Substituted thiazolo ring-fused 2-pyridones, called pilicides, possess novel antibacterial properties and inhibit pilus assembly in Uropathogenic Escherichia coli. Recently, a small number of oxygen analogues of active pilicides have shown maintained ability to disrupt pilus assembly. Here an improved methodology for the synthesis of oxazolo ring-fused 2pyridones is presented, allowing dihydro ...
