Antiproliferative Activity Compounds Isolated from the Marine Fungus Penicillium terrigenum

Cancer is still one of the greatest threats to human health. Marine fungi are abundant in constituents that can cause various bioactivities for many purposes. Compounds are the basis of drug development, leading to more studies on exploring these bioactive items. In this study, 9 compounds were isolated from Penicillium terrigenum. Four compounds isolated from the Trichocomaceae family, two compounds isolated from the Penicillium genus, as well as the other compounds, were all isolated from this strain for the first time. Compounds PTL-1 - PTL-6 were initially screened for antiproliferative activity on liver and lung cancer cells using the MTT assay in vitro. The results showed that the 6 compounds exhibited different antiproliferative activities. From the results, PTL-2, 7-ethylcamptothecin significantly inhibited the proliferation of cancer cells, highlighting it as a potential drug or lead compound.
