Trichoxanes A (1) and B (2), two novel sorbicillinoids featuring a unique cage-like 2,7-dioxa-pentacyclo[7.4.0.03,8.05,13.06,10]tridecane scaffold, were isolated from Trichoderma reesei via a molecular networking strategy. Their structures were elucidated by spectroscopic analyses, CASE, DP4+ NMR calculations, and EC...

Chemical investigation of the endolichenic fungus Aspergillus sp. TJ403-YJ22 led to the isolation and characterization of twelve new indole alkaloids, asperkaloids A-L (1-12). Compounds 1-10 represent non-paspaline-type indole-diterpenoids, whereas 11 and 12 are polyketide-indole hybrids. Notably, compounds 1 and 2 pos...
