Tetrahedron, 74(28), p.3852-3857, 2018 Caesaldecins A and B (1a/1b), a pair of epimeric cassane-type diterpenoids containing an ether linkage between C-6 and C-20 and an ?,?-butenolide ring in the northern hemisphere, were isolated from the leaves of the medicinal plant Caesalpinia decapetala (Roth)Alston, along with a new labdane-type diterpenoid, termed as 8(17),11(Z),13(E)-trien-15,18-dioic acid (2). Structures of 1 and 2 were established by extensive spectroscopic analyses, including HRESIMS, 1D and 2D NMR, and electronic circular dichroism (ECD)calculations. The in vitro antibacterial and inhibitory activities against a panel of bacteria and cancer cell lines were evaluated, respectively. Compound 2 displayed moderate antibacterial activity against the methicillin-resistant Staphylococcus aureus subsp. aureus (MRSA)with an MIC50 value of 5.99??g?mL?1.
