Synthesis and antitumor evaluation of thiophene based azo dyes incorporating pyrazolone moiety
A series of thiophene incorporating pyrazolone moieties 5a–f and 6a–c were synthesized via diazo coupling of diazonium salt of 3-substituted-2-amino-4,5,6,7-tetrahydrobenzo[b]thiophenes 1a–c with 3-methyl-1H-pyrazol-5(4H)-one, 3-methyl-1-phenyl-1H-pyrazol-5(4H)-one or 3-amino-1H-pyrazol-5(4H)-one, r...
