Description générale

Polyphosphoric acid (PPA) is an inorganic acid. Galangin-KMnO4-PPA system has been employed for the determination of tryptophan. It participates in the Skraup reaction. It is widely employed reagent for the alkylation and acylation reactions of aromatic and alkenic compounds.

Twenty-five new N-[4-(benzothiazole-2-yl)phenyl]acetamide derivatives bearing different heterocyclic ring systems were synthesized using 2-(4-aminophenyl)benzothiazole structure as a pharmacophoric group. Final compounds were screened for their potential antitumor activity in vitro against approximately 60 human tumor cell lines derived from nine neoplastic

A novel galangin-potassium permanganate (KMnO4)-polyphosphoric acid (PPA) system was found to have an outstanding response to tryptophan (Trp). Trp determination using this KMnO4 -PPA system was enhanced significantly in the presence of galangin. A highly sensitive flow-injection chemiluminescence (CL) method
