vivo by optimizing the structure of quinazolinederivatives to improve agonistic activity for rat NPR-A. A 1,4-Cis-aminocyclohexylurea moiety at 4-position and hydroxy group of d-alaninol at 2-position on the quinazoline ring were found to be important factors in improving rat NPR-A activity. We identified potent quinazoline and pyrido[2,3-d]pyrimidinederivatives against rat NPR-A, with double-digit
通过优化喹唑啉衍生物的结构以改善对大鼠NPR-A的激动活性,评估了利钠肽受体A(NPR-A)激动剂的体内作用。发现在喹唑啉环上的4-位的1,4-顺式-氨基环己基脲部分和在2-位的d-丙氨醇的羟基是改善大鼠NPR-A活性的重要因素。我们确定了针对大鼠NPR-A的强效喹唑啉和吡啶并[2,3- d ]嘧啶衍生物,其纳摩尔浓度EC 50为两位数。该体内结果显示,化合物56b的以1.0 mg / kg / min的剂量给药可显着增加大鼠血浆cGMP浓度和尿量。我们发现了新型有效的NPR-A激动剂,其激动作用类似于心钠素。

In this article, we report our efforts towards improving in vitro human clearance in a series of 5-azaquinazolines through a series of C4 truncations and C2 expansions. Extensive DMPK studies enabled us to tackle high Aldehyde Oxidase (AO) metabolism and unexpected discrepancies in human hepatocyte and liver microsomal intrinsic clearance. Our efforts culminated with the discovery of 5-azaquinazoline

this article, we report the discovery of a series of 5-azaquinazolines as selective IRAK4 inhibitors. From modestly potent quinazoline 4, we introduced a 5-aza substitution to mask the 4-NH hydrogen bond donor (HBD). This allowed us to substitute the core with a 2-aminopyrazole, which showed large gains in cellular potency despite the additional formal HBD. Further optimization led to 6-cyanomethyl-5-azaquinazoline
