Total Synthesis, Discovery and Biological Evaluation of Daldinin A Derivatives for Improving Hyperglycemia-Induced Endothelial Cell Death

抄録

Daldinins are a novel type of naturally occurring tricyclic heterocycles isolated from Daldinia concentrica. In this study, four daldinin A derivatives with different alkyl side chains were synthesized using the same synthetic protocol. Bioactivity tests first indicated that the daldinin A derivatives showed significant protection for endothelial cells against damage caused by high glucose. The derivative compound with three carbon atoms on the alkyl side exhibited the best effect.
