Abstract:
The development of combretastatin as an antimitotic agent has led to an enormous effort to design other tubulin-targeting agents. The intriguing discovery that combretastatin A-4 phosphate causes selective damage to tumor vasculature has stimulated even more activity in this field. This attention to tubulin binding agents and their antivasculature activity is highly likely to lead to significant clinical advances for the treatment of cancer. This review focuses on the development of ketones as tubulin-binding agents such as chalcones and related enones as surrogates of combretastatin and colchicine.

Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
