  使用 TRAP 转螯合手性双膦配体催化 α-（乙酰氨基）丙烯酸酯的不对称氢化：配体 P 取代基和氢气压力对对映选择性的显着影响

  摘要：

  用 [Rh(cod)2]BF4 和反式螯合手性双膦配体 (S,S)-2,2'-双 [( R)-1-(二烷基膦基)乙基]-1,1'-二茂铁[(R,R)-(S,S)-TRAPs]。在β-未取代或β-单取代的α-(乙酰氨基)丙烯酸酯[(E)-RCH=C(NHAc)CO2Me]的反应中，(R)-氢化产物的选择性随着底物β-空间需求的降低而增加取代基和配体 P 取代基以及降低氢压。在 60 °C 和 0.5 kg cm-2 氢气压力下与 EtTRAP-铑催化剂反应的 (R)-产物的选择性如下：R = H，96% ee；R = Me，92% ee；R = Ph，77% ee；R = i-Pr，57% ee。显着的空间和压力效应导致 2-(N-乙酰氨基) 肉桂酸甲酯 (R = Ph) 反应中对映选择性的显着逆转。例如，在 60 °C 和 0.1 kg cm-2 氢气压力下使用 EtTRAP 的选择性为 87%

  Design and Synthesis of Prolylcarboxypeptidase (PrCP) Inhibitors To Validate PrCP As A Potential Target for Obesity

  摘要：

  Prolycarboxypeptidase (PrCP) is a serine protease that may have a role in metabolism regulation. A class of reversible, potent, and selective PrCP inhibitors was developed starting from a mechanism based design for inhibiting this serine protease. Compound 8o inhibits human and mouse PrCP at IC(50) values of 1 and 2 nM and is not active (IC(50) > 25 mu M) against a panel of closely related proteases. It has lower serum binding than its close analogues and is bioavailable in mouse. Subchronic dosing of 8o in PrCP and WT mice at 100 mg/kg for 5 days resulted in a 5% reduction in body weight in WT mice and a reduction in PrCP KO mice.
