1,2,4-Oxadiazoles: a new class of anti-prostate cancer agents. Bioorg Med Chem Lett 2012; 22:1912-6.

Abstract
Sulfide and sulfonyl derivatives of 1,2,4-oxadiazoles were synthesized and screened by MTT assay on the prostate cancer cells, DU-145. Six compounds were identified as potential anti-prostate cancer agents with IC(50) values ranging from 0.5 to 5.1μM. These compounds exhibited good activity on the androgen independent cells PC-3, while the results were moderate on androgen dependent LNCaP cells, suggesting the possibility of a mechanism of action different from that of the bioisosteric bicalutamide. Also a very low cytotoxicity was observed on non-cancerous cells MCF-10A.
