Abstract: | The cytotoxicity of the bisN-(2-propyl)carbamates] 2 and 3 which are linked to thienoi,j-g]indole scaffolds through methylene bridges were studied as thiophene analogues of prototype 1. Compounds 2 and 3 were evaluated in vitro against 60 human-tumor cell lines derived from nine cancer-cell types and demonstrated, for compound 3 not only strong growth-inhibitory activities against leukemia cancer cells, but also fairly good activities against the growth of certain renal and ovarian cancer cell lines. Compound 2, the thieno2,3-g]indole bis-carbamate, possessed only significant (MG-MID log10 GI50 = -4.89) and selective cytoxicity against NCI-HOP92 (non-small cell lung), MALME 3M (melanoma) and IGROV 1 (ovarian) cancer cell with log10 GI50 values of -5.66, -5.48 and -5.47, respectively. |
