Synthesis and biological evaluation of novel 3,4-diaryl lactam derivatives as triple reuptake inhibitors
摘要:
A series of 3,4-diarylpyrrolidin-2-one was designed, prepared and evaluated as triple reuptake inhibitors for antidepressant. Most compounds exhibited comparable in vitro efficacy as norepinephrine and dopamine transporter reuptake inhibitors. Especially, 2i showed better potency than GBR-12909 (IC50 = 14 - nM) which was used as reference compound for dopamine transporter. In addition, 2a and 2b showed inhibition (5.17 mu M-85.6 nM) for three transporters. (C) 2013 Elsevier Ltd. All rights reserved.
A cyanide‐free platform technology for the synthesis of chiral nitriles by biocatalytic enantioselective dehydration of a wide range of aldoximes is reported. The nitriles were obtained with high enantiomeric excess of >90 % ee (and up to 99 % ee) in many cases, and a “privileged substrate structure” with respect to high enantioselectivity was identified. Furthermore, a surprising phenomenon was observed

significantly slowed the development of the catalytic asymmetric hydroarsinationreaction despite it being a highly attractive C-As bond formation methodology. In addition, there is a poor understanding of the main reaction steps in such reactions which limit further development in the field. Herein, key intermediates of the hydroarsinationreactioncatalyzed by a PCP NiII -Cl pincercomplex are presented upon
method offers a convenient and practical approach for the synthesis of α‐nitrooximes in moderate to high yields. The salient features entail mild reaction conditions, metal‐free reagent, environmentallybenignsolvent and simple experimental procedure.
