Sulfonamide derivatives of chloroquine and primaquine were synthesised and evaluated against both paclitaxel-sensitive and paclitaxel-resistant mammarian cancer cell lines. All derivatives exhibited at least 96% MDR reversal activity when coadministered with paclitaxel at 5 muM. The best compound, a chloroquine derivative, exhibited 99% MDR reversal activity when coadministered with paclitaxel at 1 muM. Molecular modelling studies reveal that these derivatives share a common pharmacophore with taxane MDR reversal agents. (C) 2001 Elsevier Science Ltd. All rights reserved.
