  Total synthesis of calebin-A, preparation of its analogues, and their neuronal cell protectivity against β-amyloid insult

  摘要：

  A total synthesis of Calebin-A (1), a novel curcuminoid isolated from turmeric (Curcuma longa, Zingiberaceae) that has been demonstrated to protect neuronal cells from beta -amyloid insult, was successfully achieved in four steps. Elaborating on this synthetic route. 13 analogues were prepared for a structure-activity relationship (SAR) study. It was found that the parent compound 1 and derivatives 21, 28, and 30 protect PC12 rat pheocromocytoma and IMR-32 human neuroblastoma cells from beta -amyloid(25-35) insult. These results suggest that hydroxy group at para-position is most critical for the expression of biological activity. (C) 2001 Elsevier Science Ltd. All rights reserved.
