QSAR analysis of some fused pyrazoles as selective cyclooxygenase-2 inhibitors: a Hansch approach.
Quantitative structure activity relationships (QSAR) for two unique series of centrally fused pyrazole ring systems have been studied for selective cyclooxygenase-2 inhibitory activity. Several statistically significant QSAR models were developed and suggest that hydrophobicity of entire molecules and a fluorine atom substitution at position 8 of the non benzene sulphonyl ring fused with central pyrazole core of series 1 compounds is crucial for improved COX-2 selectivity. Various structural and physicochemical stipulations to improve the inhibitory activities of the enzymes among individual series of compounds are also discussed. The conclusions derived may serve as an example to advance the design of new selective COX-2 inhibitors.
