  Identification of 4-amino-2-cyclohexylaminoquinazolines as metabolically stable melanin-concentrating hormone receptor 1 antagonists

  摘要：

  The optimization of the distance between two key pharmacophore features within our first hit compounds la and 2a led to the identification of a new class of potent non-peptidic antagonists for the MCH-R1, based around 4-amino-2-cyclohexylamino-quinazolines. In particular, ATC0065 (2c), N-2-[cis-4-({2-[4-Bromo-2-(trifluoromethoxy)phenyl]ethyl}amino)cyclohexyl]-N-4,N-4-dimethylquinazoline-2,4-diamine dihydrochloride, bound with high affinity to the MCH-R1 (IC50 value of 16 nM) and showed good metabolic stability in liver microsomes from human and rat.

  日期：2008.8.27

  chelate-controlled intermolecular oxidative Heck reaction is reported that proceeds with a wide range of nonresonance stabilized alpha-olefin substrates and organoboron reagents to afford internal olefin products in good yields and outstanding regio- and E: Z stereoselectivities. Pd-H isomerization, common in many Heck reactions, is not observed under these mild, oxidative conditions. This is evidenced

  据报道，一种新型螯合物控制的分子间氧化 Heck 反应与各种非共振稳定的 α-烯烃底物和有机硼试剂一起进行，以良好的收率和出色的区域和 E:Z 立体选择性提供内烯烃产品。在许多 Heck 反应中常见的 Pd-H 异构化在这些温和的氧化条件下未观察到。这可以通过出色的 E:Z 选择性（在所有检查的情况下 >20:1）、近端立体中心的光学纯度没有侵蚀以及对未受保护的醇的耐受性来证明。值得注意的是，单一金属/配体组合，Pd/双-亚砜配合物 1，在广泛的偶联伙伴上催化该反应。鉴于高选择性和广泛的范围，
