Gastric cytoprotective activity of ilicic aldehyde: Structure–activity relationships
摘要:
A series of sesquiterpene compounds possessing both eudesmane and eremophilane skeletons were tested as gastric cyto-protective agents on male Wistar rats. The presence of an alpha,beta-unsaturated aldehyde on the C-7 side chain together with a hydroxyl group at C-4 is the requirement for the observed antiulcerogenic activity. In an attempt to establish new molecular structural requirements for this gastric cytoprotective activity, a structure-activity study was performed. (c) 2005 Elsevier Ltd. All rights reserved.

A series of analogs were synthesized in a straightforward manner from naturally available sesquiterpenes ilicic acid and tessaric acid. The in vitro antiproliferative activities were examined in the human solid tumor cell lines A2780, HBL-100, HeLa, SW1573, T-47D and WiDr. The most potent analog induced considerably growth inhibition in the range 1.9-4.5 mu M. Cell cycle studies for tessaric acid derivatives indicated a prominent arrest of the cell cycle at the G(2)/M phase. Damage to the cells was permanent as determine by the so called 24+24 drug schedule. (C) 2009 Elsevier Ltd. All rights reserved.
