The invention of new anti-inflammatory agents peaks the first phase of an existing and fast paced effort to exploit a novel, target for nonsteroidal antiinflammatory drugs (NSAIDs).Aseries of molecules has been reported as anti-inflammatory agents belonging to the class of phenothiazine nucleus. Various physicochemical and steric parameters were calculated. Quantitative structure-activity relationship models were generated employing sequential multiple regression method using VALSTAT. Statistically significantmodelswithR-values 0.949 and 0.946were obtained. Models were validated using leave one out and bootstrapping methods. The result shows that Boiling point, Stretch energy, Connolly molecular area and Partition coefficient are contributing to biological activity.Among these, Connollymolecular area and partition coefficient plays an important role as positive contribution is seen in the models. The obtained and validated models bring important structural insight to aid the design of novel anti-inflammatory activity prior to their synthesis.
