Kumar, Rajesh published the artcileSynthesis, anti-microbial evaluation, and QSAR studies of 4-amino-3-hydroxy-naphthalene-1-sulfonic acid derivatives, Name: 4-Amino-3-hydroxynaphthalene-1-sulfonic acid, the publication is Medicinal Chemistry Research (2012), 21(12), 4301-4310, database is CAplus.
A series of 4-amino-3-hydroxy-naphthalene-1-sulfonic acid derivatives was synthesized and tested in vitro for its anti-microbial potential. The results of anti-microbial studies indicated that derivatives I [R1 = H, R2 = R3 = R4 = OMe; R1 = R3 = Cl, R2 = R4 =H] were found to be most effective ones. The mt-QSAR model for anti-microbial activity revealed the importance of topol. parameter, valence zero-order mol. connectivity index (0蠂v) in describing the anti-microbial activity of synthesized 4-amino-3-hydroxy-naphthalene-1-sulfonic acid derivatives
Medicinal Chemistry Research published new progress about 116-63-2. 116-63-2 belongs to naphthyridine, auxiliary class Sulfonic acid,Amine,Naphthalene,Alcohol,Organic Pigment, name is 4-Amino-3-hydroxynaphthalene-1-sulfonic acid, and the molecular formula is C10H9NO4S, Name: 4-Amino-3-hydroxynaphthalene-1-sulfonic acid.
