Abstract
Abstract: 25-azacycloartanol (1) is a potent inhibitor of S-adenosyl-L-methionine-cycloartenol-C-24-methyltransferase and of S-adenosyl-L-methionine-24-methylene lophenol-C-28-methyltransferase, two microsomal enzymes of maize (Zea mays) embryos. Addition of 1 to a suspension of bramble (Rubus fruticosus) cells grown in vitro resulted in a strong decrease of the 24-ethylsterol content and in a dramatic increase of sterols lacking an alkyl group at C-24.
