A biosynthetic gene cluster for the bioactive fungal sesterterpenoids variecolin (1) and variecolactone (2) was identified in Aspergillus aculeatus ATCC 16872. Heterologous production of 1 2 achieved oryzae by expressing sesterterpene synthase VrcA cytochrome P450 VrcB. Intriguingly, replacement VrcB with homologous P450s from other terpenoid pathways yielded three new analogues (5–7). Analysis compounds' anticancer activity vitro vivo revealed that although 5 had comparable activities,...
