The article contains the following contents:
Title compounds, e.g. I (R = H2NCH2CH2NH, 1-pyrrolidinyl, 3-hydroxy-1-pyrrolidinyl), possess moderate cytotoxic activity. Structure-activity relationships of title compounds were investigated by changing substituents at N-1 and C-7 positions and the core ring structure itself and evaluated the synthesized compounds against several murine and human tumor cell lines. The 2-thiazolyl group at the N-1 position of the naphthyridine structure is the best substituent for antitumor activity and regarding core ring structure, the naphthyridine derivative is the most active followed by pyridopyrimidine analog. At the C-7 position, aminopyrrolidine derivatives are more effective than other amines or thioether derivatives I (R = 3-amino-4-methoxy-1-pyrrolidinyl, 3-amino-3-methyl-1-pyrrolidinyl, 3-aminopyrrolidinyl) were determined to be effective in vitro and in vivo antitumor assays, and their activity was comparable to that of etoposide.5-Bromothiazol-2-amine(cas: 3034-22-8Recommanded Product: 5-Bromothiazol-2-amine) was used in this study.
5-Bromothiazol-2-amine(cas: 3034-22-8) belongs to anime. Halogenation, in which one or more hydrogen atoms of an amine is replaced by a halogen atom, occurs with chlorine, bromine, and iodine, as well as with some other reagents, notably hypochlorous acid (HClO). With primary amines the reaction proceeds in two stages, producing N-chloro- and N,N-dichloro-amines, RNHCl and RNCl2, respectively. With tertiary amines, an alkyl group may be displaced by a halogen.Recommanded Product: 5-Bromothiazol-2-amine
