Yaqin FAN, Chunjiao JIANG, Peihai LI, et al. A new chloro-azaphilone derivative with pro-angiogenesis activity from the hadal trench-derived fungus
A new chloro-azaphilone derivative chaetoviridin L (

) along with four known analogues
namely
chaetomugilin A (

)
chaetoviridin E (

)
chaetomugilin O (

)
and chaephilone D (

)
is isolated and identified from the culture extract of
Chaetomium globosum
YP-106
a deep-sea derived fungus obtained from the hadal zone seawater collected in the Yap Trench. Their structures were determined based on detailed interpretation of nuclear magnetic resonance (NMR) spectroscopic
mass spectrometry (MS) data analysis and comparison with the reported literature. The absolute configuration of the new compound was established by quantum chemical calculations of electronic circular dichroism (ECD). All the isolated compounds were evaluated for pro-angiogenesis activity using zebra fish model. Compounds

significantly promoted the angiogenesis in a dose-dependent manner and thus
these compounds might be used as promi
sing molecules for the treatment of cardiovascular disease.
