Synthesis and SAR of new pyrazolo[4,3-h]quinazoline-3-carboxamide derivatives as potent and selective MPS1 kinase inhibitors
摘要:
The synthesis and SAR of a series of novel pyrazolo-quinazolines as potent and selective MPS1 inhibitors are reported. We describe the optimization of the initial hit, identified by screening the internal library collection, into an orally available, potent and selective MPS1 inhibitor. (C) 2011 Elsevier Ltd.

Compounds of the formula (I), and pharmaceutically acceptable salts and in vivo hydrolysable esters thereof are described. Also described are processes for their preparation and their use as medicaments, particularly medicaments for producing a cell cycle inhibitory (anti cell proliferation) effect in a warm blooded animal, such as man.
using deep eutectic solvents (DESs) as nonconventional, “green” and “innocent” reaction media, has been accomplished successfully. The combination of either glycerol or urea with choline chloride (ChCl) proved to be effective for decreasing the reaction time to about 4–6 h in contrast to the 10–12 h usually required for the same reaction run in toxic and volatile organicsolvents and under an argon
2-氨基咪唑 (2-AI) 的高产一锅两步合成,利用 α-氯酮和胍衍生物之间的空气杂环脱水过程,并使用深共熔溶剂 (DES) 作为非常规的“绿色”和“无辜”反应介质,已成功完成。事实证明,甘油或尿素与氯化胆碱 (ChCl) 的组合可有效将反应时间缩短至约 4-6 小时,而在有毒和挥发性有机溶剂中进行相同反应通常需要 10-12 小时,并且在氩气气氛下。此外,使用 ChCl-尿素作为 DES 还可以通过简单的后处理程序直接分离三芳基取代的 2-AI 衍生物,包括过滤和结晶,并允许 DES 混合物的循环利用。
