Abstract: A novel series of imidazo [1,2-a]pyridinederivatives has been designed, synthesized and tested for the anti-proliferativeactivity against three different human cancer cell lines. Most of thesynthesized compounds exhibit anti-proliferative activi

We report herein the discovery of antileishmanial molecules based on the imidazo[1,2-a]pyridine ring. In vitro screenings of imidazopyridines belonging to our chemical library, toward the promastigotes stage of Leishmania donovani, J774A.1 murine and HepG2 human cells, permitted to identify three selective hit-compounds (12, 20 and 28). New derivatives were then synthesized to allow structure-activity and -toxicity relationships analyses, enabling to characterize a lead-compound (44) displaying both a high potency (IC 50 = 1.8 μM) and a good selectivity index, in comparison with three antileishmanial reference drug-compounds (amphotericin B, miltefosine and pentamidine). Moreover, lead-compound 44 also exhibits good in vitro activity against the intracellular amastigote stage of L. donovani. Thus, the 6-halo-3-nitro-2-(phenylsulfonylmethyl)imidazo[1,2-a]pyridine scaffold appears as a new promising selective antileishmanial pharmacophore, especially when substituted at position 8 by a bromine atom.
Synthesis by the S(RN)1 reaction of a new series of imidazo[1,2-a]pyridine derivatives with pharmacological potentialities

The study of S(RN)1 reaction between 2-chloromethyl-3-nitroimidazo[1,2-a] pyridine and 2-nitropropane salts has been extended to various aliphatic, cyclic and heterocyclic nitronate anions. From C-alkylation products, base-promoted nitrous acid elimination afforded new potential pharmacological derivatives with a trisubstituted double bond at the 2 position.
