Product Overview
TS CB30865 is a highly potent cytotoxic agent. The compound inhibits isolated mammalian thymidylate synthase (TS), but this inhibition is insufficient to account for its cellular toxicity. Thymidylate synthase (TS) is a critical enzyme in the de novo synthesis of thymidylate (dTTP) and has long been recognized as a target for chemotherapeutic intervention.

In vitro
CB30865 was the most potent growth inhibitory agent (IC50 values in the range 1-100 nM for several mouse and human cell types). Against W1L2 cells, the analogues of CB300179 and CB300189 demonstrated reduced potency in the presence of exogenous thymidine (dThd), and against a W1L2:C1 TS overproducing cell line. In contrast, CB30865 retained activity in these systems. No cell cycle redistribution was observed following exposure (4-48 h) to an equitoxic concentration of CB30865.
In vivo
The in vivo evaluation of CB30865 was hampered because of its low aqueous solubility.
