Preliminary note: effect of microtubule inhibitors with acrylophenone structure on Triton WR 1339 induced hyperlipidemia in rats.

Acrylophenone derivatives having in vitro antimicrotubular activity very similar to that of Colchicine were tested on Triton WR 1339 induced hyperlipidemia in rats. By inducing a disorganization of the microtubular system these compounds decreased the movement of very low density lipoproteins (VLDL) to the extracellular space and consequently decreased hypertriglyceridemia. On the other hand, contrary to Colchicine, these derivatives decreased cholesterolemia more significantly and this could be explained by a second action mechanism.
