Abstract: A series of carboline derivatives with amino or guanidinium were synthesized and evaluated in vitro against anti-Mycobacterium tuberculosis and for antiproliferative activities against nine human cancer cell lines. The compounds 1-(4-hydroxyphenyl)-3-carboxamide(ethylamine) β-carboline (24.9 µg mL-1) and 1-(4-methoxyphenyl)-3-carboxamide(ethylamine) β-carboline (26.9 µg mL-1) were the most active against M. Tuberculosis (MTB). Compounds 1-(4-hydroxyphenyl)-3-carboxamide(ethylamine) β-carboline and 1-(4-methoxyphenyl)-3-carboxamide(propylamine) β-carboline, which had the same substituted groups, inhibited the growth of all human tumor cell lines with growth inhibitory activity (GI50) values from 1.37 to 9.20 mmol L-1. Also in this series, compounds 1-(4-hydroxyphenyl)-3-carboxamide(propylamine) β-carboline and 1-(3-nitrophenyl)-3-carboxamide(propylamine) β-carboline demonstrated significant activity against NCI/ADR cells. Among compounds with a terminal guanidine group, compounds 1-(4-hydroxyphenyl)-3-carboxamide(ethyl)guanidine β-carboline (27.8 µg mL-1) and 1-(3-nitrophenyl)-3-carboxamide(ethyl)guanidine β-carboline (37.4 µg mL-1) demonstrated the greatest activity against MTB. Additionally, compounds 1-(4-methoxyphenyl)-3-carboxamide(ethyl)guanidine β-carboline (GI50 = 0.45 mmol L-1) effectively inhibited growth and was highly selective against NCI/ADR. The in silico study revealed that 1-(4-hydroxyphenyl)-3-carboxamide(ethylamine) β-carboline, 1-(4-methoxyphenyl)-3-carboxamide(ethylamine) β-carboline, 1-(4-hydroxyphenyl)-3-carboxamide(propylamine) β-carboline, 1-(4-methoxyphenyl)-3-carboxamide(propylamine) β-carboline and 1-(3-nitrophenyl)-3-carboxamide(propylamine) β-carboline compounds follow the rules established by Lipinski, suggesting that this compound has no problems with oral bioavailability.
