缺乏脂肪胺的黑色素浓缩激素受体1拮抗剂:新型1-(咪唑并[1,2 - a ]吡啶-6-基)吡啶-2(1 H)-一衍生物的合成与结构-活性关系
摘要:
为了发现具有改善的安全性的黑色素浓缩激素受体1(MCHR1)拮抗剂,我们假设,如果化合物支架的双环基序与Asp123和/或Tyr272相互作用,则迄今为止报道的大多数拮抗剂中使用的脂肪胺都可以被去除。 MCHR1。我们从化合物设计中排除了p K a <8的临界值的脂族胺,并在面向CNS的化学空间(受四个描述符(TPSA,ClogP,MW和HBD计数)限制)中探索了不含脂族胺的MCHR1拮抗剂。 。对具有高固有结合亲和力的MCHR1新型双环基序的筛选确定了咪唑并[1,2- a ]吡啶环(以化合物6a和6b表示),然后对中央脂肪族酰胺键进行环化,导致发现了一种有效的,口服可生物利用的MCHR1拮抗剂4-[((4-氯苄基)氧基] -1-(2-环丙基-3-甲基咪唑并[1,2- a] ] pyridin-6-yl)pyridin-2(1 H)-one 10a。它在饮食诱导的肥胖大鼠中表现出低的hER

affinity for MCHR1 identified the imidazo[1,2-a]pyridine ring (represented in compounds 6a and 6b), and subsequent cyclization of the central aliphatic amide linkage led to the discovery of a potent, orally bioavailable MCHR1 antagonist 4-[(4-chlorobenzyl)oxy]-1-(2-cyclopropyl-3-methylimidazo[1,2-a]pyridin-6-yl)pyridin-2(1H)-one 10a. It exhibited low potential for hERG inhibition and phospholipidosis
