The novel synthesis and SAR studies of 6-methyluracils as human GnRH receptor antagonists are discussed. Introduction of a small methyl substituent at the beta-position from N3 of the uracil improved the GnRH binding potency by 5- to 10-fold. The best compound from the series had binding affinity of 5 nM (K(i)) to the human GnRH receptor.
讨论了新型的合成和SAR研究作为人类GnRH受体拮抗剂的6-甲基尿嘧啶。在尿嘧啶的N 3的β-位引入一个小的甲基取代基可使GnRH结合力提高5至10倍。该系列中最好的化合物对人GnRH受体的结合亲和力为5 nM(K(i))。
