Herein is described the design, synthesis, and enzymatic activity of a series of substituted pyrazinones as inhibitors of the TF/VIIa complex. These inhibitors were designed to explore replacement and variation of the P1 amidine described previously [J. Med. Chem.2003, 46, 4050]. The P1 needle replacements were selected based upon their reduced basicity compared to the parent phenyl amidine (pKa approximately
本文描述了一系列取代的吡嗪酮作为TF / VIIa复合物抑制剂的设计,合成和酶促活性。设计这些抑制剂以探索先前描述的P1 idine的置换和变异[J. 中 Chem.2003,46,4050]。根据与母体苯基am(pKa约为12)相比降低的碱性,选择P1针头替代品。影响化合物口服生物利用度的一个因素是该化合物在肠道中的电离状态。该研究的理想结果是确定一种口服生物利用的TF-VIIa抑制剂。
