The Uses of 6,6'-Ureylene-bis(1-naphthol-3-sulfonic acid)
7,7''-(Carbonylbis(azanediyl))bis(4-hydroxynaphthalene-2-sulfonic acid) (cas# 134-47-4) is a pharmacologically active compound capable of selective nonbisphosphonate inhibition of human geranylgeranyl diphosphate synthase, and inhibition of shikimate dehydrogenase and shikimate kinase in shikimate pathway of Helicobacter pylori.
What are the applications of Application
AMI-1, free acid is a chemical shown to inhibit arginine, in vitro, with no inhibitory effect on lysine
Preparation
7,7' -Urylenebis(4-hydroxynaphthalene-2- sulfonic acid) [134-47-4] , J acid urea, carbonyl J acid, is produced by reacting the sodium salt of J acid with phosgene in aqueous solution at 30℃ and maintaining alkalinity with sodium carbonate. After being heated to 80℃, the product is salted out with sodium chloride (yield ca. 100 %). It is used to produce C.I. Direct Orange 26; C.I. Direct Reds 4, 14, 23, and 80; and C.I. Direct Brown 112.
