Rational design and synthesis of 4-substituted 2-pyridin-2-ylamides with inhibitory effects on SH2 domain-containing inositol 5′-phosphatase 2 (SHIP2)
摘要:
Novel 4-substituted 2-pyridin-2-ylamides were developed using in-silico ligand-based drug design (LBDD) in an attempt to identify inhibitors of SH2-containing 5'-inositol phosphatase 2 (SHIP2), which is implicated in insulin-resistant type 2 diabetes. Among the compounds synthesized, N-[4-(4-chlorobenzyloxy) pyridin-2-yl]-2-(2,6-difluorophenyl)- acetamide (CPDA, 4a) was identified as a potent SHIP2 inhibitor. CPDA was found to enhance in vitro insulin signaling through the Akt pathway more efficiently than the previously reported SHIP2 inhibitor AS1949490, and ameliorated abnormal glucose metabolism in diabetic (db/db) mice.

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
(MCH) is an attractive target for antiobesity agents, and numerous drug discovery programs are dedicated to finding small-molecule MCH receptor 1 (MCHR1) antagonists. We recently reported novel pyridine-2(1H)-ones as aliphatic amine-free MCHR1antagonists that structurally featured an imidazo[1,2-a]pyridine-based bicyclic motif. To investigate imidazopyridine variants with lower basicity and less potential
