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...

(±)-Hypericandrone A (HCA, 1), an unprecedented pair of enantiomeric polycyclic polyprenylated acylphloroglucinols (PPAPs), and its biosynthetic congener hypericandrone B (HCB, 2) were isolated from the fruits of Hypericum androsaemum. Compound 1 features a unique 2-cyclopentane-bicyclo[3.3.0]octane scaffold, while 2 p...
Non-small cell lung cancer (NSCLC) remains one of the leading causes of cancer-related mortality worldwide, highlighting the urgent need for effective therapeutic agents. Natural products represent an important source of novel anticancer compounds. In this study, we investigated the anti-NSCLC activity of 10,11-dehydro...
