| Description | Shepherdin 79-87 acetate is a peptidomimetic antagonist of the complex between Hsp90 and survivin, another key regulator of tumor cell viability. |
| In vitro | When added to prostate carcinoma (PC3, DU145) or HeLa cells, shepherdin caused concentration-dependent and complete loss of cell viability[1]. |
| In vivo | Shepherdin-RV (50 mg/kg, i.p., daily) nearly completely ablated tumor growth in immunocompromised mice prostating carcinoma PC3 cells. In a breast cancer xenograft model that employs MCF-7 cells adapted in vivo, injection of Shepherdin-RV resulted in exponentially growing tumors independently of estrogen supplementation, which was unaffected by saline administration. Shepherdin-RV (50 mg/kg i.p. daily) uniformly inhibited the growth of these more aggressive tumors (p = 0.01) throughout a 23-day or 11-day treatment regimen. Shepherdin treatment resulted in nearly complete loss of Akt levels in tumor cells and severely attenuated expression of survivin[1]. |
