Abstract
Compounds of general formula (I), (II), (III) and (V) are described for use in modulating microtubule polymerisation and in the treatment of associated disease states. Use of compounds (I), (III) and (V) in the treatment of kinase-associated disease states is also described. Further described are novel compounds of formula (II), (III) and (V).
