  1. NT = not tested; MG-MID = average sensitivity of derivative against all cancer cell (µM); GI50 = concentration of the derivative required for 50% of maximal growth inhibition; TGI = concentration of the derivative required for total growth inhibition; LC50 = concentration of the derivative required to kill 50% of population.
