  Structure-Based Design of Novel Guanidine/Benzamidine Mimics:  Potent and Orally Bioavailable Factor Xa Inhibitors as Novel Anticoagulants

  摘要：

  As part of an ongoing effort to prepare orally active factor Xa inhibitors using structure-based drug design techniques and molecular recognition principles, a systematic study has been performed on the pharmacokinetic profile resulting from replacing the benzamidine in the P1 position with less basic benzamidine mimics or neutral residues. It is demonstrated that lowering the pK(a) of the P1 ligand resulted in compounds (3-benzylamine, 15a; 1-aminoisoquinoline, 24a; 3-aminobenzisoxazole, 23a; 3-phenylcarboxamide, 22b; and 4-methoxyphenyl, 22a) with improved pharmacokinetic features mainly as a result of decreased clearance, increased volume of distribution, and enhanced oral absorption. This work resulted in a series of potent and orally bioavailable factor Xa inhibitors that ultimately led to the discovery of SQ311, 24a. SQ311, which utilizes a 1-aminoisoquinoline as the P1 ligand, inhibits factor Xa with a K-i of 0.33 nM and demonstrates both good in vivo antithrombotic efficacy and oral bioavailability.

  Twenty eight aryl pyrazole derivatives containing 5-fluorouracil were designed and synthesised via the key intermediate 1-aryl-3-methyl-1 H-pyrazole-5-carboxylic acid. The structures of target compounds were confirmed by ¹H NMR, FT-IR, EA and their insecticidal activities were evaluated. The bioassays revealed that aryl pyrazole derivatives containing 5-fluorouracil exhibited excellent insecticidal activities against Culex pipiens and Musca domestica at a concentration of 0.1%. Some compounds still showed good insecticidal activities even at a concentration of 0.05%.

  通过关键中间体 1-芳基-3-甲基-1 H-吡唑-5-羧酸，设计并合成了含有 5-氟尿嘧啶的 28 种芳基吡唑衍生物。通过 1H NMR、FT-IR 和 EA 确认了目标化合物的结构，并评估了它们的杀虫活性。生物测定结果表明，含有 5-氟尿嘧啶的芳基吡唑衍生物在 0.1% 的浓度下对喙库蚊和家蝇具有极佳的杀虫活性。一些化合物即使在 0.05% 的浓度下仍表现出良好的杀虫活性。
