  Identification of 1-Arylmethyl-3- (2-aminoethyl)-5-aryluracil as Novel Gonadotropin-Releasing Hormone Receptor Antagonists

  摘要：

  Based on SAR from hicyclic GnRH antagonists such as 6-aminomethyl-7-arylpyrrolo[1,2-a]pyrimid-4-ones (1) and 2-aryl-3-aminomethylimidazolo[1,2-a]pyrimid-5-ones (2a,b), a series of novel uracil compounds (4) were derived as the GnRH antagonists. Their syntheses and initial SAR are discussed herein. This is the first time that monocycle-based GnRH receptor antagonists are reported.

  N-Allyl derivatives of uracil (U), thymine (T) and 6-methyluracil (6-MU) were prepared, and their pharmacological activities (hypnotic activity and anticonvulsant activity against pentylenetetrazol (PTZ) -induced seizures) and interactions with three sedative-hypnotics [pentobarbital (PB), barbital (B) and diazepam (DZ)] were investigated in mice. N1, N3-Diallyluracil (DAU) alone exhibited hypnotic and anticonvulsant activities. None of the other allyl derivatives showed both pharmacological activities. As regards interactions, most of the compounds tested prolonged PB-induced sleep at either 80 or 160 mg/kg, i.p. Further, U, T, and 6-MU (160 mg/kg, i.p.) also prolonged the PB-induced sleeping time. DAU showed a prolonging effect on PB-induced sleep when given by intracerebroventricular (i.c.v.) injection. DAU, N1, N3-diallylthymine (DAT) and N1-monoallyluracil (N1-MAU) significantly prolonged the B-induced sleeping time at a dose of 160 mg/kg, i.p. Further, DAU and DAT (40 mg/kg, i.p.) enhanced DZ-induced motor incoordination. These results indicate that U and related compounds possess central nervous system (CNS) - depressant effects and DAU is the most potent among the N-allyl derivatives tested.

  制备了尿嘧啶（U）、胸腺嘧啶（T）和6-甲基尿嘧啶（6-MU）的N-烯丙基衍生物，及其药理活性（对戊四氮（PTZ）引起的癫痫发作的催眠活性和抗惊厥活性）以及与三种镇静剂的相互作用- 在小鼠身上研究了安眠药[戊巴比妥（PB）、巴比妥（B）和地西泮（DZ）]。 N1、N3-二烯丙基尿嘧啶（DAU）单独表现出催眠和抗惊厥活性。其他烯丙基衍生物均未表现出这两种药理活性。至于相互作用，大多数化合物在 80 或 160 mg/kg（腹膜内注射）下测试了 PB 诱导的睡眠延长。此外，U、T 和 6-MU（160 mg/kg，腹腔注射）也延长了 PB 诱导的睡眠时间。当通过脑室内 (i.c.v.) 注射时，DAU 对 PB 诱导的睡眠有延长作用。 DAU、N1、N3-二烯丙基胸腺嘧啶 (DAT) 和 N1-单烯丙基尿嘧啶 (N1-MAU) 在腹腔注射 160 mg/kg 的剂量下显着延长 B 诱导的睡眠时间。此外，DAU 和 DAT（40 mg/kg，腹腔注射）增强了 DZ 引起的运动不协调。这些结果表明 U 和相关化合物具有中枢神经系统 (CNS) 抑制作用，并且 DAU 是测试的 N-烯丙基衍生物中最有效的。

  Based on the SAR from bicyclic gonadotropin-releasing hormone (GnRH) antagonists such as 6-aminomethyl-7-aryl-pyrrolo[1,2-alpha]pyrimid-4-ones (5) and 2-aryl-3-aminomethyl-imidazolo[1,2-alpha]pyrimid-5-ones (6a,b), a series of novel uracil compounds (8) were derived as GnRH antagonists. The synthesis and SAR studies of 6-methyluracils as human GnRH receptor antagonists are discussed herein. Introduction of a small methyl substituent at the beta-position of the N3 side-chain improved the GnRH binding potency by 5-10-fold. Introduction of a methyl group of (R)-configuration at the alpha-carbon of the N-3 side-chain gave a modest improvement in binding affinity over the unsubstituted ethylene analogues. This modification enabled us to make uracil compounds without the labile 2-pyridylethyl motif on the basic nitrogen while still maintained excellent potency against the hGnRH receptor.
