Tenuazonic acid is a putative nonhost-selective mycotoxin isolated from Alternaria alternate. Tenuazonic acid blocks electron transport beyond primary quinone acceptor (QA) by interacting with D1 protein and it is a broad-spectrum and effective photosyste
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
Encecalin and demethylencecalin are major phytotoxic compounds isolated from Helianthella quinquenervis (Hook) A Gray (Asteraceae), they inhibit photosystem II (from water to 2,5-dibromo-3-methyl-6-isopropyl-1,4 p-benzo-quinone).They retard seed germinati
