Preclinical evaluation of the anti tumour activity of new epoxyde derivatives

As a follow-up to our initial results on the antineoplastic activity of alpha-1,3,5-triglycidyl-s-triazinetrione (alpha TGT, NSC-296934, Teroxirone), many new epoxyde derivatives were tested against murine tumours, mostly against P388 leukaemia, to determine their antineoplastic role and to characterize their specific effect against tumour cells in vivo, as well as to select an analogue with higher anti-cancer properties and superior pharmacological properties. Triglycidyl urazol (TGU, NSC-332488) showed the highest therapeutic activity and a good level of water-solubility which makes this agent a good candidate for phase-one clinical trials.
