SYNTHESIS AND ANTIPROLIFERATIVE ACTIVITY OF 3-AMINO-N-PHENYL-1H-INDAZOLE-1-CARBOXAMIDES
2010
Recently our research group has reported the synthesis of some 3-amino-N-phenyl-1H-indazole-1-carboxamides able to inhibit at low micromolar concentrations the cell growth of many neoplastic cell lines. The above compounds are unsubstituted in the indazole nucleus and this gives the hope to obtain more active compounds if appropriate substituents are beared by the above nucleus. So, several new N-phenyl-1H-indazole-1-carboxamides 1c-h and 4l,m were prepared by reacting phenyl isocyanates 3a,b with 3-amino-1H-indazoles 2c,e,g, or 1H-indazole 2l respectively. Chemical trasformations of compounds 1a,b and 1g,h gave 3-acetamido-N-phenyl-1H-indazole-1-carboxamides 5a,b, and 3,5-diamino-N-phenyl-…
Synthesis and antiproliferative activity of 3-amino-N-phenyl-1H-indazole-1-carboxamides
2007
Abstract A series of new 3-amino-N-phenyl-1H-indazole-1-carboxamides 10 have been prepared from commercially available phenyl isocyanate precursors 8 and 3-aminoindazole 9. Some of the synthesized compounds were evaluated for their in vitro antineoplastic activity against 60 human cell lines derived from seven clinically isolated cancer types (lung, colon, melanoma, renal, ovarian, brain, and leukemia) according to the NCI standard protocol. The test results indicated that 3-amino-1H-indazole-1-carboxamides 10 were endowed with an interesting antiproliferative activity. The most active compounds of this series, 10d,e, were able to inhibit cell growth of many neoplastic cell lines at concent…
Synthesis of substituted 3-amino-N-phenyl-1H-indazole-1-carboxamides endowed with antiproliferative activity
2010
Abstract Several new N-phenyl-1H-indazole-1-carboxamides 1c–h and 4l,m were prepared by reacting phenyl isocyanate derivatives 3a,b with 3-amino-1H-indazole derivatives 2c,e,g or 1H-indazole 2l respectively. Chemical transformations of compounds 1a,b and 1g,h gave 3-acetamido-N-phenyl-1H-indazole-1-carboxamide derivatives 5a,b, and 3,5-diamino-N-phenyl-1H-indazole-1-carboxamide derivatives 4i, j respectively. Finally, 3,5-diacetamido-N-phenyl-1H-indazole-1-carboxamide derivatives 6a,b were prepared by acetylation of 4i, j. Some of synthesized compounds were evaluated for their in vitro antiproliferative activity against the full NCI tumor cell lines panel derived from nine clinically isolat…
