Brassinazole (S6781-GRP)

Brassinazole (BRZ) is a potent inhibitor of brassinosteroid (BR) biosynthesis with IC50 of ~ 1 μM, that has been developed to probe the myriad functions of brassinosteroids. Brassinosteroids are a class of phytohormones with essential roles in plant growth and development, including the promotion of stem elongation and cell division.
