Four novel arylbiamidine series were studied showing particular tautomerism and H-bonding structure highlighting their promising druglike features toward anticancer applications.
The invention relates to novel imidazolamino compounds. Also disclosed are methods of treating cancer by using one of these compounds and pharmaceutical compositions containing one of these compounds.

A procedure has been proposed for the synthesis of a series of substituted N-(1,3-thiazol-2-yl)-pyrimidin-2-amines and N-(pyrimidin-2-yl)thioureas by reactions of diethyl 2-(ethoxymethylidene)malonate and ethyl 2-(ethyoxymethylidene)-3-oxobutanoate with 1,3-thiazol-2-ylguanidines and amidinothiourea, respectively. Preliminary screening has revealed high inhibitory activity of ethyl 2-(carbamothioy
Designed from a high throughput screened hit compound, novel 2-amino-1-thiazolyl imidazoles were synthesized and demonstrated cytotoxicity against human cancer cells. 1-(4-Phenylthiazol-2-yl)-4-(thiophen-2-yl)-1H-imidazol-2-amine (compound 2), a 2-amino-1-thiazolyl imidazole, inhibited tubulin polymerization, interacted with the colchicine-binding sites of tubulins, and caused cell cycle arrest at the G2/M phase in human gastric cancer cells. Disruption of the microtubule structure in cancer cells by compound 2 was also observed. Compound 2 concentration-dependently inhibited the proliferation of cancer cells in histocultured human gastric and colorectal tumors. Given orally, compound 2 prolonged the lifespans of leukemia mice intraperitoneally inoculated with the murine P388 leukemic cells. We report 2-amino-1-thiazolyl imidazoles as a novel class of orally active microtubule-destabilizing anticancer agents.
