Ferulenol, a sesquiterpene prenylated coumarin derivative, exhibits potent antimycobacterial activity and haemorrhagic action. This compound selectively targets succinate ubiquinone reductase within the ubiquinone cycle as its specific mode of inhibition.
Calpinactam is a fungal metabolite originally isolated from M. alpina that has antimycobacterial activity. It is active against M. smegmatis (MIC = 0.78 μg/ml) but not a panel of 13 other bacteria and fungi. Calpinactam increases survival in a silkworm model of M. smegmatis infection (ED50 = 5 μg/larva).
Cabraleadiol displays antimycobacterial activity against Mycobacterium tuberculosis, it also is weakly cytotoxic to a breast cancer (BC) cell line. Cabraleadiol inhibits photosystem II (PS II) and induces the appearance of small G band which is related wi
