Inhibitors of Acyl CoA:Cholesterol Acyltransferase
摘要:
Conformational restriction of previously disclosed acyclic diphenylethyl)diphenylacetamides led to the discovery of several potent inhibitors of acyl CoA:cholesterol acyltransferase (ACAT). cis-[2-(4-Hydroxyphenyl)-1-indanyl]diphenylacetamide (4a) was the mo st potent ACAT inhibitor identified (IC50 = 0.04 mu M in an in vitro rat hepatic microsomal ACAT assay, ED(50) = 0.72 mg/kg/day in cholesterol-fed hamsters).

A green and efficient catalytic approach for the selective synthesis of imines in air at room temperature was achieved with the aid of newly synthesised diruthenium(II) complexes [(η6-p-cymene)2Ru2Cl2(µ-L)] containing substituted 1,2-diacylhydrazine ligands. All the new complexes were fully characterised by analytical and spectroscopic techniques. The solid-state structure of a representative complex

Dual Heterogeneous Catalyst Pd–Au@Mn(II)-MOF for One-Pot Tandem Synthesis of Imines from Alcohols and Amines
A new Mn(II) metal–organicframework (MOF) 1 was synthesized by the combination of 4,4,4-trifluoro-1-(4-(pyridin-4-yl)phenyl)butane-1,3-dione (L) and Mn(OAc)2 in solution. 1 features a threefold-interpenetrating NbO net containing honeycomb-like channels, in which the opposite Mn(II)···Mn(II) distance is 23.5075(10) Å. Furthermore, 1 can be an idealplatform to support Pd–Au bimetallic alloy nanoparticles

A transition metal‐free protocol has been developed for the oxidativecoupling of primary amines to imines and azobenzenes, thiols to disulfides, and 2‐aminothiophenols to benzothiazoles, offering excellent yields. The advantageous features of the present environmentally benign methodology include the usage of biocompatable and green reaction conditions such as solvent, room temperature reactions,

A novel reaction involving cyano transfer from benzophenone cyanohydrin to aldehydes and imines was realized by usingdibutyltindimethoxide as a catalyst. Various cyanohydrins and α-amino nitriles were obtained in moderate to high yields by this reaction. Ketimines also showed remarkable reactivity as cyano acceptors under conventional reaction conditions. This catalytic reaction was further applied
