ABSTRACT
Two new alkenyl phenol derivatives, namely pestalol F (1) and pestalol G (2), along with two known compounds, pestalachloride A (3) and pestalotiopsin J (4), were isolated from the culture of the fungus Pestalotiopsis clavata JSQ 12. The structures of these compounds were primarily elucidated by MS, NMR and specific rotation data analysises. These secondary metabolites of Pestalotiopsis clavata were reported for the first time. Compound 2 displayed interesting cytotoxic activity against MCF-7 cell line with the IC50 value of 29.16 µM, whereas compound 3 exhibited moderate activity towards A549 cell line with the IC50 value of 35.71 µM. The positive control 5-FU showed cytotoxic effects on MCF-7 and A549 cell lines with the respective IC50 values of 26.70 and 26.07 µM. Compounds 1 and 2 displayed mild antibacterial activities against Staphylococcus aureus with MIC values of 128 and 64 µg/mL (MIC of positive control, penicillin, was 0.016 µg/mL), respectively.
