Clavukoellians A-F, Highly Rearranged Nardosinane Sesquiterpenoids with Antiangiogenic Activity from Clavularia koellikeri

J Nat Prod. 2019 May 24;82(5):1331-1337. doi: 10.1021/acs.jnatprod.9b00100. Epub 2019 Apr 17.

Abstract

Six new nardosinane-type sesquiterpenoids, clavukoellians A-F (1-6), together with one new neolemnane-type sesquiterpene, 4- O-deacetylparalemnolin D (7), were isolated from the marine soft coral Clavularia koellikeri. The structures of compounds 1-7 were elucidated by NMR spectroscopy, ECD analysis, and quantum chemical calculation methods. Compounds 1 and 7 demonstrated significant antiangiogenic activities in wound healing assays on HUVECs.
