Research Abstract

In this research grant, we intended to clarify the mode of action of oxygenated steroids, physalins, by means of organic synthesis and chemical biology. First, the constructions of E- and C-ring moieties from cage-shaped DFGH-ring compound of physalin B, whose synthetic strategy has been already established, were investigated. The synthesis of DEFGH-ring compounds were realized by adopting our original strategy to construct the unique cage-shaped skeleton as a key reaction for the precursor, which possessed an appropriate functionality at C17 on F-ring. For C-ring moiety, the establishing the strategy to form the C-C bonds at C13 or C14 of the precursor of DEFHG-ring compounds was also successful. Furthermore, structure-activity relationship study of synthetic DEFGH-ring compounds and natural products of oxygenated steroids isolated from physalis plants was carried out. As a result, we found that physalin B showed potent inhibitory activity for NF-κB activation stimulated by TNF-α and have different mode of action with other oxygenated steroids.
