Secretory phospholipase A(2) (sPLA(2)) is an important enzyme that plays a key role in various inflammatory diseases including cancer and its inhibitors have been developed as preventive or therapeutic agents. In the present study, a series of new indole containing isoxazole derivatives (10a-10o) is synthesized and evaluated for their sPLA(2) inhibitory activities. All compounds (10a-10o) showed significant sPLA(2) inhibition activities both in vitro and in vivo studies which is substantiated in in silico studies. Among all the tested compounds, 100 showed potent sPLA(2) inhibition activity, that is comparable or more to ursolic acid (positive control). Further studies demonstrated that 100 showed in vitro antiproliferative activity when tested against MCF-7 breast and DU145 prostate cancer cells. Furthermore, compounds 10a-10o obeyed lipinsky's rule of 5 and suggesting druggable properties. The in vitro, in vivo and in silico results are encouraging and warrant pre-clinical studies to develop sPLA(2)-inhibitory compound 10o as novel therapeutic agent for various inflammatory disorders and several malignancies.
