ABSTRACT:
The invention relates to novel 2-benzimidazolyl-, 2-benzoxazolyl- and 2-benzothiazolyl hydrazones that are derived from 2-formylpyridine, 2-acylpyridines, acetyldiazines and acetyl(iso)quinolines. The invention also relates to a novel method for producing 2-benzimidazolyl-, 2-benzoxazolyl- and 2-benzothiazolyl hydrazones and to their use as useful anti-cancer therapeutic agents. The novel compounds are also active against multidrug-resistant cancer cells.
