  描述：

  ethyl 2-{6-[(3,5-difluorobenzyl)amino]-3-azabicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxylate 在 甲醇 、 水 、 1-羟基苯并三唑 、 盐酸-N-乙基-Nˊ-(3-二甲氨基丙基)碳二亚胺 、 三乙胺 、 sodium hydroxide 作用下， 以 四氢呋喃 、 甲醇 、 二氯甲烷 、 N,N-二甲基甲酰胺 为溶剂， 反应 34.0h， 生成 N-hydroxy-2-{6-[(4-cyanobenzyl)amino]-3-azabicyclo[3.1.0]hex-3-yl}pyrimidine-5-carboxamide trifluoroacetate

  Discovery of 2-(6-{[(6-Fluoroquinolin-2-yl)methyl]amino}bicyclo[3.1.0]hex-3-yl)-N-hydroxypyrimidine-5-carboxamide (CHR-3996), a Class I Selective Orally Active Histone Deacetylase Inhibitor

  摘要：

  A novel series of HDAC inhibitors demonstrating class I subtype selectivity and good oral bioavailability is described. The compounds are potent enzyme inhibitors (IC50 values less than 100 nM), and improved activity in cell proliferation assays was achieved by modulation of polar surface area (PSA) through the introduction of novel linking groups. Employing oral pharmacokinetic studies in mice, comparing drug levels in spleen to plasma, we selected compounds that were tested for efficacy in human tumor xenograft studies based on their potential to distribute into tumor. One compound, 21r (CHR-3996), showed good oral activity in these models, including dose-related activity in a LoVo xenograft. In addition 21r showed good activity in combination with other anticancer agents in in vitro studies. On the basis of these results, 21r was nominated for clinical development.
