  Cyclomaltoheptaose mixed esters of anti-inflammatory drugs and short-chain fatty acids and study of their enzymatic hydrolysis in vitro

  摘要：

  In an effort to enhance the drug-loading capacity of cyclomaltoheptaose (beta-cyclodextrin, beta CD) and to combine the function of anti-inflammatory drugs with short-chain fatty acids (SCFA), ternary esters incorporating seven copies of an anti-inflammatory drug and 14 copies of a SCFA onto a P-cyclodextrin core were designed and prepared. Acetic, propionic, or butyric esters were introduced at secondary OH groups, and ibuprofen, flurbiprofen, or felbinac was attached to primary OH groups through ester bonds. Heptakis[2,3-di-O-butanoyl-6-O-2-(biphenyl-4-yl)-ethanoyl]-cyclomaltoheptaose was very stable in aqueous and esterase solution. It was hydrolyzed by alpha-amylase (4 units/mL) with t(1/2) value of 18 h. The total released amount of biphenyl acetic acid was 38% after 24 h when the esterase was added after the alpha-amylase hydrolysis. The present results suggest that these nine beta CD conjugates may release the anti-inflammatory drug in the colonic contents. (C) 2009 Published by Elsevier Ltd.
