In vitro anti-Trypanosoma cruzi activity of ternary copper(II) complexes and in vivo evaluation of the most promising complex. Biomed Pharmacother 2018; 109:157-166. [PMID: 30396072 DOI: 10.1016/j.biopha.2018.10.057] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Revised: 10/11/2018] [Accepted: 10/11/2018] [Indexed: 12/12/2022] Open
Abstract
In order to improve the previously observed antichagasic activity of Cu(II) complexes containing 2-chlorobenzhydrazide (2-CH), we report herein the synthesis and anti-Trypanosoma cruzi activity of novel copper complexes containing 2-methoxybenzhydrazide (2-MH), 4-methoxybenzhydrazide (4-MH) and three α-diimine ligands, namely, 1,10-phenanthroline (phen), 2,2-bipyridine (bipy) and 4-4'-dimethoxy-2-2'-bipyridine (dmb). Two of these complexes showed higher in vitro anti-Trypanosoma cruzi activity when compared to benznidazole, the main drug used in Chagas disease treatment. One of them, the copper complex with 4-MH and dmb, [Cu(4-MH)(dmb)(ClO4)2], exhibited a higher selectivity index than that recommended for preclinical studies. Considering this observation, complex [Cu(4-MH)(dmb)(ClO4)2] was selected for preliminary in vivo assays, which verified that this compound was able to reduce parasitemia by 64% at the peak of infection. Further investigations were performed on all compounds. The Cu(II) complexes bind to ct-DNA with Kb values in the range of 103-104 M-1, with [Cu(4-MH)(dmb)(ClO4)2] showing the highest Kb value (1.45 × 104 M-1). Molecular docking simulations predicted that [Cu(4-MH)(dmb)(ClO4)2] binds in the minor groove of the double helix of ct-DNA and forms one hydrogen bond.
