    Product Description

    HE-3235 is a synthetic adrenal hormone, an androstanediol analog, that acts as an androgen receptor antagonist.1 In an androgen receptor-dependent manner, it downregulates anti-apoptotic genes, while increasing the expression of pro-apoptotic genes, thus stimulating apoptosis.1 HE-3235 has been shown to inhibit androstenediol-dependent LNCaP cell tumor growth both in vitro (IC50 = 6 nM) and in xenograft models in vivo.1,2
