Allgemeine Beschreibung

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
