The structures of 19 were elucidated on the basis of 1D and 2D NMR and MS spectroscopic data. Compounds 38 feature an α,β-unsaturated carbonyl moiety within their spirotetronate skeletons. Moreover, compounds 312 displayed strong to moderate antibacterial activities against Gram positive bacteria Bacillus thuringiensis BT01 and B. subtilis BS01 with MIC values ranging from 0.016 to 8.0 μg/mL. %I ACS Publications
