differentiation, growth, and maintenance of male reproductive organs, and also has effects on hair and skin. In this paper, we report the synthesis of nonsteroidal AR antagonists having a 4-benzyl-1-(2H)-phthalazinone skeleton. Among the synthesized compounds, 11c with two ortho-substituents on the phenyl group potently inhibited SC-3 cell proliferation (IC50: 0.18 μM) and showed high wt AR-binding affinity
雄激素受体(AR)在多种生理功能(包括男性生殖器官的分化,生长和维持)中起着重要作用,并且对头发和皮肤也有影响。在本文中,我们报告了具有4-苄基-1-(2 H)-酞嗪酮骨架的非甾体类AR拮抗剂的合成。在合成的化合物中,在苯基上带有两个邻位取代基的11c可以有效抑制SC-3细胞增殖(IC 50:0.18μM),并表现出与羟基氟他胺相当的高AR结合亲和力(IC 50:10.9μM)。 (3)。化合物11c还抑制了含有T877A突变的AR的LNCaP细胞的增殖。与AR配体结合域对11c的对接研究表明,苄基对拮抗作用很重要。这些酞嗪酮衍生物可用于研究AR拮抗剂的潜在临床应用。
