Renchangianins F and G: two new sesquiterpenoids from Kadsura renchangiana

Abstract

Phytochemical investigation on the stems of Kadsura renchangiana led to the isolation of two new sesquiterpenoids, renchangianins F and G (1 and 2). Their structures were elucidated by spectroscopic methods, including 2D NMR techniques. The in vitro cytotoxic activities of the isolates were studied against HepG2, A549, and LN229 cancer cell lines.

New Cadinane Sesquiterpenes from the Stems of Kadsura heteroclita

“…In the last few decades, phytochemical work on the family Schisandraceae has resulted in a seminal contribution to novel structural frameworks for triterpenoidal skeletons [1,2,3,4]. Recently, some promising sesquiterpenes has also been reported from the plants of family Schisandraceae [5,6,7,8,9,10]. In our previous research, we reported the identification of several bioactive lignanoids from the genus kadsura [11] that highlight the immense diversity in the chemical constituents of these plants as well as in their important biological activities.…”
