Ligand-based discovery of N-(1,3-dioxo-1H,3H-benzo[de]isochromen-5-yl)-carboxamide and sulfonamide derivatives as thymidylate synthase A inhibitors
摘要:
Phenolnaphthalein derivatives show potential for pharmacological activity as inhibitors of thymidylate synthase (TS) but difficulties in their synthesis and derivatization hinder their development. A deconstruction approach aimed at identifying a suitable new scaffold was proposed. A new scaffold was identified and two compound libraries based on this scaffold were designed. The carboxamide library ( Library B) showed specific inhibition activity against Escherichia coli TS, whereas the sulfonamide library ( Library C) showed a non-specific inhibition profile against hTS. N-(1,3-Dioxo-1H,3H-benzo[de] isochromen-5-yl)-sulfonamide derivatives, 1C and 9C, showed one order of magnitude improvement in inhibition constant against hTS with respect to the starting lead and represent potential compounds for further lead development.
