Combretastatins: An Overview of Structure, Probable Mechanisms of Action and Potential Applications
Combretastatins are a class of closely related stilbenes
(combretastatins A), dihydrostilbenes (combretastatins B), phenanthrenes
(combretastatins C) and macrocyclic lactones (combretastatins D) found
in the bark of Combretum caffrum (Eckl. \& Zeyh.) Kuntze, commonly known
as the South African bush willow. Some of the compounds in this series
have been shown to be among the most potent antitubulin agents known.
Due to their structural simplicity many analogs have also been
synthesized. Combretastatin A4 phosphate is the most frequently tested
compounds in preclinical and clinical trials. It is a water-soluble
prodrug that the body can rapidly metabolize to combretastatin A4, which
exhibits anti-tumor properties. In addition, in vitro and in vivo
studies on combretastatins have determined that these compounds also
have antioxidant, anti-inflammatory and antimicrobial effects.
Nano-based formulations of natural or synthetic active agents such as
combretastatin A4 phosphate exhibit several clear advantages, including
improved low water solubility, prolonged circulation, drug targeting
properties, enhanced efficiency, as well as fewer side effects. In this
review, a synopsis of the recent literature exploring the
combretastatins, their potential effects and nanoformulations as lead
compounds in clinical applications is provided
