  Synthesis and evolution of neuroprotective effects of oxymatrine derivatives as anti‐Alzheimer’s disease agents

  摘要：

  AbstractWhile screening for natural product scaffolds as potential anti‐Alzheimer's disease (AD), oxymatrine (OMT) was found to relieve symptoms of AD through diminishing death of neuronal cells caused by microglia‐induced inflammation. In this study, 13 derivatives of OMT were synthesized and their neuroprotective effects were evaluated on Aβ1‐42‐induced PC12 cells using MTT method. In addition, the best neuroprotective potencies were obtained with compounds 4, 6e, and 6f, which were selected for evaluation of decrease in IL‐1β and TNF‐α in Aβ1‐42‐treated PC12 cells. Collectively, these data reveal that derivatives 6e and 6f possess the best ability of diminish IL‐1β production and reverse cell damage in all compounds, which are possible to develop as therapeutic agents for AD.

  Oxymatrine (1) is a natural anti-hepatitis B virus (HBV) drug that down-regulates host heat-stress cognate 70 (Hsc70) expression through a mechanism different from that of nucleosides. Taking Hsc70 as a target against HBV, 26 novel N-substituted matrinic acid analogs were designed, synthesized and evaluated for their regulation of Hsc70 mRNA expression with 1 as the lead. The SAR analysis revealed that (i) the carboxyl group at the 11-position was required for activity; (ii) introducing of a substituent on the nitrogen atom at the 12-position of 3, especially substituted benzyl, might significantly improve the activity. Among these analogs, compound 9p possessing N-p-methoxylbenzyl afforded an increased anti-HBV effect in comparison with 1. We consider 9p a promising anti-HBV candidate. (C) 2011 Elsevier Ltd.
