Structure-activity study on antiinflammatory pyrazole carboxylic acid hydrazide analogs using molecular connectivity...

The relationship between molecular connectivity indices and the antiinflammatory activity of a series of pyrazole carboxylic acid hydrazide analogs has been investigated. The values of molecular connectivity index, valence molecular connectivity index, and a modified index, termed as atomic molecular connectivity index for 76 compounds, were computed and active ranges were identified. Each compound was assigned an activity which was subsequently compared with the reported activity against lipoxygenase enzyme. Predictions with a degree of accuracy above 80% were observed using the valence molecular connectivity index.
