A Novel Synthesis of 2-Arylpyrrolo[1,2-a]pyrimid-7-ones and Their Structure–Activity Relationships as Potent GnRH Receptor Antagonists
摘要:
In the process of developing GnRH receptor antagonists, a novel base-catalyzed cyclization of compounds 5a-b was discovered, which led to the formation of the 2-aryl pyrrolo[1,2-a]pyrimid-7-one core stuctures 6a-b. These intermediates were further modified at positions 1, 2, 4 and 6 to afford a series of potent GnRH antagonists with low nanomolar K-i values. (C) 2002 Elsevier Science Ltd. All rights reserved.
therapeutics. We used molecular modeling-assisted structural optimization starting with the low micromolar potency compound 9 to discover compound 13c, a highly potent and orallybioavailable Axl inhibitor. Selectivity profiling showed that 13c could inhibit the well-known oncogenic kinase Met with equal potency to its inhibition of Axl superfamily kinases. Compound 13c significantly inhibited cellular Axl and
受体酪氨酸激酶 Axl 在促进癌症进展、转移和耐药性中发挥重要作用,并已被确定为抗癌治疗的有希望的靶点。我们从低微摩尔效力化合物9开始,使用分子建模辅助结构优化来发现化合物13c ,这是一种高效且可口服生物利用的 Axl 抑制剂。选择性分析表明, 13c可以抑制众所周知的致癌激酶 Met,其抑制 Axl 超家族激酶的效力相同。化合物13c显着抑制细胞Axl和Met信号传导,抑制Axl和Met驱动的细胞增殖,并抑制Gas6/Axl介导的癌细胞迁移或侵袭。此外, 13c在 Axl 驱动和 Met 驱动的肿瘤异种移植模型中表现出显着的抗肿瘤功效,在耐受良好的剂量下导致肿瘤停滞或消退。所有这些有利的数据使13c成为癌症治疗的有前途的候选药物。

The present invention discloses peptide aldehydes which are potent and specific inhibitors of thrombin, their pharmaceutically acceptable salts, pharmaceutically acceptable compositions thereof, and methods of using them as therapeutic agents for disease states in mammals characterized by abnormal thrombosis.
The action of the aspartyl protease renin is the rate-limiting initial step of the renin-angiotensin-aldosterone system. Therefore, renin is a particularly promising target for blood pressure as well as onset and progression of cardiovascular and renal diseases. New pyrimidine derivatives 5–14 were designed in an attempt to enhance the renin inhibitory activity of compound 3 identified by our previous
