  发现新型二氢嘧啶和异羟肟酸杂合物作为有效的幽门螺杆菌脲酶抑制剂

  摘要：

  设计、合成了两个新系列的二氢嘧啶-异羟肟酸杂化物（4a-4l和5a-5l），并评估了体外幽门螺杆菌脲酶抑制作用。体外酶抑制筛选导致发现了三种有效的脲酶抑制剂 2-[[4-(4-羟基苯基)-6-oxo-1,6-dihydropyrimidine-2-yl]-amino] -N-羟基乙酰胺 ( 4g )、2-[[4-(4-氯苯基)-6-氧代-1,6-二氢嘧啶-2-基]-氨基] -N-羟基乙酰胺( 4b )和3-[[4-(3) -甲氧基苯基)-6-氧代-1,6-二氢嘧啶-2-基]-氨基] -N-羟基丙酰胺( 5l )。复方4g显示出出色的脲酶抑制作用，IC 50值为 14 ± 1 nM，这表明它与金属 Ni ++离子、Gly279、His221、Ala365、Asp362、Asn168、Arg338 和脲酶活性位点的 His322 残基有很强的相互作用。此外，与标准乙酰异羟肟酸 (IC 50 –

  Isocytosine-based inhibitors of xanthine oxidase: Design, synthesis, SAR, PK and in vivo efficacy in rat model of hyperuricemia

  摘要：

  Structure-activity relationship studies were carried out for lead generation following structure-guided design approach from an isocytosine scaffold identified earlier for xanthine oxidase inhibition. A 470-fold improvement in in vitro IC50 was obtained in the process. Five most potent compounds with nanomolar IC50 values were selected for pharmacokinetics and in vivo experiments. The best compound showed good in vivo activity when administered intraperitoneally but was not active by oral route. The results suggest that improvement in oral exposure could improve the in vivo efficacy of this series. (C) 2012 Elsevier Ltd. All rights reserved.

  2-amino-5-bromo-6-phenyl-4(3H)-pyrimidinone. An analogue study incorporating a series of 2-amino-5-substituted-6-arylpyrimidinones revealed that the most potent interferon inducers were mono- and difluorophenyl analogues. These same analogues were also potent antiviral agents against Semliki Forest virus and herpes simplex type 1. In addition the monomethoxyphenyl analogues were potent antiviral agents but weak interferon

  发现2-氨基-5-溴-6-苯基-4（3H）-嘧啶酮具有干扰素诱导作用和抗病毒活性。包含一系列2-氨基-5-取代-6-芳基嘧啶酮的类似物研究表明，最有效的干扰素诱导剂是单-和二氟苯基类似物。这些相同的类似物也是针对Semliki Forest病毒和1型单纯疱疹的有效抗病毒剂。此外，单甲氧基苯基类似物是有效的抗病毒剂，但是弱干扰素诱导剂。相对适度的结构变化导致生物活性发生巨大变化。循环干扰素水平与全身抗病毒活性之间的相关性相对较差。
