Summary
The activity of three iron chelators, methyl [2′-(2-hydroxyphenyl)-2′-thiazoline-4′-carboxylate] (MTL); 2′-(2-hydroxyphenyl)-2′-thiazoline-4′-carboxylic acid (TFAL); and 2-hydroxyphenyl-imido-ethyl-ether (Imidate), regarding antiproliferative, cytocidal, and cell-cycle effects are reported and compared with hydroxyurea (HU). In vitro, against L1210 and P388 murine neoplasms, MTL and TFAL displayed substantially greater antiproliferative activity than HU, although Imidate displayed no appreciable activity. MTL also induced a statistically more complete G1/S cell-boundary block than did HU at equimolar concentrations (100 μM). The IC50 values produced by MTL and TFAL were low enough (≤20 μM)to warrant further testing of these chelators as potential antineoplastic agents.
