Design and Synthesis of Androgen Receptor Antagonists with Bulky Side Chains for Overcoming Antiandrogen Resistance
摘要:
Incorporation of curcumin and beta-ionone into one chemical entity led to identification of a novel antiandrogen with two bulky side chains, 6, which is a pure antagonist of the wild-type and the T877A, W741C, and H874Y mutated androgen receptors (AR), showing no cross-reactivity with progesterone receptor and low micromolar cytotoxicity in LNCaP, PCa-2b, 22Rv1, and C4-2B prostate cancer cells. Molecular modeling indicates 6 adopts a "Y"-shape conformation and forms multiple hydrogen bonds with AR backbone.

The present invention relates to the synthesis of a series of ionone and curcumin derivatives as multi-targeting agents effective against both hormone-sensitive and hormone-independent cancers. In particular, the present invention is directed to a distinct class of bifunctional antiandrogens, which inhibit both AR and IKBkinases (IKK). A series of ionone-based chalcones were synthesised and their in vitro cytotoxicity against prostate cancer cell lines were demonstrated. A series of derivatives formed by reacting ionone-based chalcones and hydrazines demonstrate substantial antiproliferative activities in prostate cancer, breast cancer and lung cancer cell lines.
