Optimization of Pharmacokinetics through Manipulation of Physicochemical Properties in a Series of HCV Inhibitors
摘要:
A novel series of HCV replication inhibitors based on a pyrido[3,2-d]primidine core were optimized for pharmacokinetics (PK) in rats. Several associations between physicochemical properties and PK were identified and exploited to guide the design of compounds. In addition, a simple new metric that may aid in the prediction of bioavailability for compounds with higher polar surface area is described (3*HBD-cLogP).

The present application provides novel quinazolines and azaquinazolines and pharmaceutically acceptable salts thereof. Also provided are methods for preparing these compounds. These compounds are useful in for co-regulating RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways by administering a therapeutically effective amount of one or more of the compounds of formula (I), wherein X, Y, T and R4, and R6 to R8' are defined herein, to a patient. By doing so, these compounds are effective in treating conditions associated with the dysregulation of the RAS/RAF/MEK/ERK and PI3K/AKT/PTEN/mTOR pathways. A variety of conditions can be treated using these compounds and include diseases which are characterized by abnormal cellular proliferation. In one embodiment/ the disease is cancer.

This invention provides di-, tri- and tetra-substituted pyrido(3,2-d)pyrimidine derivatives with specific substituting patterns, their pharmaceutically acceptable salts, N-oxides, solvates, pro-drugs and enantiomers, possessing unexpectedly desirable pharmaceutical properties, in particular being highly active antiviral agents. The invention also provides use of such derivatives in the treatment of viral infections and pathologic conditions associated therewith, including hepatitis C.
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。
