Commiphoroids G1—G3, H and I, Five Terpenoid Dimers As Extracellular Matrix Inhibitors from Resina Commiphora

Main observation and conclusionCommiphoroids G1—G3, H and I (1—5), five new terpenoid dimers were isolated from Resina Commiphora. Their structures and absolute configurations were determined by using spectroscopic, computational and crystallographic methods. Biological evaluation of these terpenoid dimers against renal fibrosis reveals that 5 inhibits extracellular matrix components including fibronectin and collagen I in a concentration‐dependent manner.
