The steroidogenic enzyme 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) is a therapeutic target in the management of androgen-sensitive diseases such as prostate cancer and benign prostate hyperplasia. In this Letter, we designed and synthesized the first fluorescent inhibitor of this enzyme by combining a fluorogenic dansyl moiety to the chemicalstructure of a known inhibitor of 17β-HSD3. The
类固醇生成酶17β-羟基类固醇脱氢酶3(17β-HSD3)是雄激素敏感性疾病(如前列腺癌和良性前列腺增生)的治疗靶标。在这封信中,我们通过将荧光的丹磺酰基部分与已知的17β-HSD3抑制剂的化学结构相结合,设计并合成了该酶的第一种荧光抑制剂。合成的化合物3是一种有效的荧光化合物(λ EX = 348 nm和λ EM = 498纳米)。它穿过细胞膜,保持其荧光特性,并分布在过表达17β-HSD3的LNCaP细胞内,在该细胞中它抑制4-雄甾烯3,17-二酮向雄激素睾丸酮的转化(IC 50 = 262 nM)。
