Abstract The heartwood of Pterocarpus santalinus contains two major redpigments, santalin-A and santalin-B which are partial methyl ethers of the same polyphenol (santalin). For locating the position of the methoxyl groups, alkali fission and permanganate oxidation of the mixed ethyl methyl ethers are the most convenient. By this method santalin-A has been shown to be 9,1O,12- tri- O -methylsantalin

2-phenylimidazo[4,5-b]pyridines (e.g., sulmazole) or 8-phenylpurines. Furthermore, all imidazo[4,5-c]pyridine analogues we tested were orally active; in contrast, only one of the imidazo[4,5-b]pyridinederivatives, sulmazole, was significantly active. One of several highly active compounds in the [4,5-c] series was 50 (LY175326, 2-[2-methoxy-4-(methylsulfinyl)phenyl]-1H-imidazo[4,5-c]pyridine hydrochloride)
Isolation and structure elucidation of two phytoalexins (1 and 2), produced by diseased paper mulberry and designated as broussonins A and B, are described. These phytoalexins are characterized structurally by a 1,3-diphenylpropane skeleton.
