Design, synthesis and In vitro evaluation of potent, novel, small molecule inhibitors of plasminogen activator inhibitor-1
摘要:
We have synthesized and evaluated a series of tetramic acid-based and hydroxvquinolinone-based inhibitors of plasminogen activator inhibitor-1 (PAI-1). These studies resulted in the identification of several compounds which showed excellent potency against PAI-1. The design, synthesis and SAR of these compounds are described.

A Convenient Method for Preparation of α-Imino Carboxylic Acid Derivatives and Application to the Asymmetric Synthesis of Unnatural α-Amino Acid Derivative
glycine derivatives for the synthesis of α-imino carboxylic acidderivatives. Using this methodology, utilization of unstable glyoxic acidderivatives was avoided. Furthermore, using this methodology we synthesized novel α-imino carboxylic acidderivatives such as α-imino phenyl ester, perfluoroalkyl etsers, imides, and thioester. The asymmetric Mannich reaction of those novel imine derivatives with 1

photoredox catalyst under an aerobic atmosphere. A wide variety of primary amines, including amino acids and more complex amines are competent coupling partners. Various electron‐rich aromatics and heteroaromatics are useful scaffolds in this reaction, as are complex, biologically active arenes. We also describe the ability to functionalize arenes that are not oxidized by an acridinium catalyst, such as

We have synthesized and biologically evaluated 1,4-diazepane derivatives as T-type calcium channel blockers. In this study, we discovered compound 4s, a potential T-type calcium channel blocker with good selectivity over hERG and N-type calcium channels. In addition, it exhibited favorable pharmacokinetic characteristics for further investigation of T-type calcium channel related diseases. (C) 2010 Elsevier Ltd. All rights reserved.
