这封信详细介绍了我们为开发具有改进的药理特性的新型三环 M 4 PAM 支架所做的努力。这项努力涉及一种“回接”策略,以取代 3-amino-4,6-dimethylthieno[2,3- b ]pyridine-2-carboxamide 核心,从而发现了两个新的三环核心:7,9 -二甲基吡啶并[3',2':4,5]噻吩并[3,2-d]嘧啶核和2,4-二甲基噻吩并[2,3 - b :5,4-c']联吡啶核。两个三环核心都显示出对人类 M 4受体的低纳摩尔效力。

group was the preferred substituent at one inhibitor terminus and also identified a urea moiety as the optimal linker to the remainder of the inhibitor structure. Further SAR optimization of the other inhibitor terminus ultimately yielded compound 50 as a urea-containing Namptinhibitor which exhibited excellent biochemical and cellular potency (enzyme IC50 = 0.007 μM; A2780 IC50 = 0.032 μM).

烟酰胺磷酸核糖基转移酶(Nampt)是一种有希望的抗癌靶标。虚拟筛选确定了一种硫脲类似物化合物5为新型强效Nampt抑制剂。在5的共晶结构的指导下,SAR探索表明相应的脲化合物7表现出相似的效价,并具有改善的溶解度特征。这些研究还表明3-吡啶基是在一个抑制剂末端的优选取代基,并且还确定了脲部分是抑制剂结构其余部分的最佳连接基。另一个抑制剂末端的进一步SAR优化最终产生了化合物50作为具有尿素的Nampt抑制剂,它具有出色的生化和细胞效价(酶IC 50 = 0.007μM; A2780 IC 50 = 0.032μM)。当在A2780卵巢肿瘤异种移植模型中口服给药时,化合物50还显示出优异的体内抗肿瘤功效(在第17天观察到TGI为97%)。

Using a multiplexed, reporter gene-based, high throughput screen, we identified 9-fluoro-7-hydroxy-3-methyl-5-oxo-N-(pyridin-3-ylmethyl)-2,3-dihydro-1H,SH-pyrido- [3,2,1-ij]quinoline-6-carboxamide as a TLR2 agonist. Preliminary structure-activity relationship studies on the carboxamide moiety led to the identification of analogues that induce chemokines and cytokines in a TLR2-dependent manner. These results represent new leads for the development of vaccine adjuvants.
