Abstract
Meleagrin and oxaline, which belong to the roquefortine alkaloids with a unique dihydroindole spiroamide framework, have significant bioactivities, especially tumor cell inhibitory activity. In order to discover the requefortine alkaloids, Penicillium sp. OUCMDZ-1435 was fished and identified from marine fungi using molecular probe technology. Meleagrin (1) and oxaline (2) were isolated from it. In addition, we first reported that compounds 1 and 2 could effectively inhibit the proliferation and metastasis of the human HepG2 cell and induce HepG2 cell apoptosis and cell cycle arrest in the G2/M phase. Additionally, the fermentation of Meleagrin (1) was optimized to increase its yield to 335 mg/L. These results provided bioactive inspiration and fungus resources for roquefortine alkaloid development.

Abstract
Meleagrin B is a terpene-alkaloid hybrid natural product that contains both the conidiogenone and meleagrin scaffold. Their derivatives show diverse biological activities. We characterized the biosynthesis of (-)-conidiogenone B (1), which involves a diterpene synthase and a P450 monooxygenase. In addition, an α,β-hydrolase (Con-ABH) was shown to catalyze an aza-Michael addition between 1 and imidazole to give 3S-imidazolyl conidiogenone B (6). Compound 6 was more potent than 1 against Staphylococcus aureus strains.
