General description

Polyphosphoric acid (PPA) is an inorganic acid. Galangin-KMnO4-PPA system has been employed for the determination of tryptophan.[1] It participates in the Skraup reaction.[2] It is widely employed reagent for the alkylation and acylation reactions of aromatic and alkenic compounds.[3]

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

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
