Resveratrol/Hydrazone Hybrids: Synthesis and Chemopreventive Activity against Colorectal Cancer Cells.

A series of resveratrol/hydrazone hybrids were obtained and elucidated by spectroscopic analysis. All compounds were evaluated against colorectal cancer cells (SW480 and Sw620) and nonmalignant cell lines (HaCaT and CHO-K1) to establish the selectivity index. Among the hybrids evaluated, compounds and displayed the highest cytotoxic activity with IC values of = 6.

Fe chelating quinoline-hydrazone hybrids with proven cytotoxicity, leishmanicidal, and trypanocidal activities.

Neglected tropical diseases cause great concern in developing countries where there are millions of reported infected humans. It is well known that chelating agents inhibit parasite growth by depriving them of iron, an essential nutrient for cell growth and division; therefore, in this work, we use computational methods to explore the Fe3+ chelating abilities of a set of 10 quinoline-hydrazone hybrids (28 substructures in total) whose cytotoxicity, leishmanicidal, and trypanocidal activities are known. We quantify stabilizing effects in the bare molecules as well as in the iron complexes and show how iron complexation reduces the structural space.

Synthesis, leishmanicidal, trypanocidal and cytotoxic activity of quinoline-hydrazone hybrids.

Cutaneous leishmaniasis and Chagas disease are vector-borne parasitic disease causing serious risks to million people living in poverty-stricken areas. Both diseases are a major health problem in Latin America, and currently drugs for the effective treatment of these diseases have important concerns related with efficacy or toxicity than need to be addressed. We report herein the synthesis and biological activities (cytotoxicity, leishmanicidal and trypanocidal activities) of ten quinolone-hydrazone hybrids.
