The binding free energies on human tubulin of selected colchicine and thiocolchicine compounds were determined. Two methods were used for the determination of binding free energies: one is based on theoretical prediction simulating the dissociation of the compound from tubulin using a series of molecular dynamics simulations, and the other method involves a series of experiments that measured the affinity of the compound on a synthetically expressed and purified tubulin protein using a spectrofluorometric technique.
