Here we first identified a novel pyridazinone derivative, compound 3711, as a nonnucleosidic hepatitis B virus (HBV) inhibitor in a cell model system. 3711 decreased extracellular HBV DNA levels by 50% (50% inhibitory concentration [IC50]) at 1.5 ± 0.2 μM and intracellular DNA levels at 1.9 ± 0.1 μM, which demonstrated antiviral activity at levels far below those associated with toxicity. Both ...
Pyridazine plays a significant role in pharmaceuticals particularly in the field of medicinal chemistry. Several 4-substituted-benzylidene-6-substituted-phenyl-dihydro-pyridazin-3(2H)-one derivatives (3a-q) were synthesized and evaluated for their antimicrobial activities with an aim to obtain promising antitubercular agents. In the first step, 6-aryl-tetrahydro-pyridazin-3-ones (2) were prepar...
