Synthesis, dimerization, and biological activity of hexaoxygenated chalcones related to calythropsin and combretastatins

Nat Prod Lett. 2002 Jun;16(3):187-93. doi: 10.1080/10575630290010993.

Abstract

Five new hexaoxygenated chalcones and one new chalcone photodimer were synthesized and their cytotoxicity against leukemia cell line L-1210 was studied. The three more active compounds were tested for their activity on the inhibition and promotion of tubulin assembly and it was found that these chalcones do not interfere with the tubulin-microtubule system at cytotoxic concentrations, and therefore operate by some different mechanism of action.
