4-substituted pyridine or a 1-substituted imidazole ring and the carboxamide nitrogen atom showed the best combination of potencies in the two assays. Several of these compounds were found to be orallyactive inhibitors of LTE4-induced bronchoconstriction in the guinea pig and LTE4-induced skin wheal formation in the rat. One of the most potent analogues, 2-(1-methyl-ethyl)-N-(1H-imidazol-1-ylbutyl)-11-oxo-11H-pyrido
The present invention relates to compounds of formula (A), as further defined herein, having antiviral activity, more specifically HIV (Human Immunodeficiency Virus) replication inhibiting properties. The invention also relates to pharmaceutical compositions comprising an effective amount of such compounds as active ingredients. The invention further relates to the use of such compounds, optionally combined with one or more other drugs having antiviral activity, for the treatment of animals suffering from viral infections, in particular HIV infection.
The instant invention provides for compounds which comprise fused pyrazoles that inhibit CHK1 activity. The invention also provides for compositions comprising such inhibitory compounds and methods of inhibiting CHK1 activity by administering the compound to a patient in need of treatment of cancer.
