Abstract

The syntheses of new N-polysubstituted imidazo [4, 5-b] pyridine-7-one (IP, 5 and 8a–8f) and indazole-4, 7-dione (ID, 9 and 10) derivatives are described. The binding affinity of IP and ID towards the recombinant Nucleotide Binding Domain NBD1 of Cryptosporidium parvum CpABC3 was evaluated by intrinsic fluorescence quenching. IP induced a moderate quenching of the intrinsic fluorescence of H6-NBD1 whereas IDs 9 and 10 showed a ...
