Discovery of Novel Pyrazole Derivatives as Potent Neuraminidase Inhibitors against Influenza H1N1 Virus.

abstract：:A series of 1H,3H-thiazolo[3,4-a]benzimidazoles were synthesized and tested for their in vitro antitumour activity against 60 human tumour cell lines. Some derivatives exhibited both tumour growth inhibition activity and cellular selectivity. In particular, compound 8c, the most active of the series, was very active t...
