The phytoalexin cyclobrassinin is a plant defense that has additional importance since it inhibits brassinin hydrolase, a phytoalexin detoxifying enzyme produced by the plant pathogen Alternaria brassicicola. Hence, the 1,3-thiazino[6,5-b]indole scaffold of cyclobrassinin has great application as a lead structure
