rIL-10 plays a major role in restricting exaggerated inflammatory and immune responses, thus preventing tissue damage. However, the restriction of inflammatory and immune responses by IL-10 can also favor the development and/or persistence of chronic infections or neoplasms. Dogs that succumb to canine leishmaniasis (CanL) caused by L.

Leishmaniasis is a parasitic disease caused by protozoa of the genus Leishmania, which has very limited treatment options and affects poor and underdeveloped populations. The current treatment is plagued by many complications, such as high toxicity, high cost and resistance to parasites; therefore, novel therapeutic agents are urgently needed. Herein, the synthesis, characterization and in vitro leishmanicidal potential of new complexes with the general formula [RuCl(TMP)(dppb)] (1), [PtCl(TMP)(PPh)]PF (2) and [Cu(CHCOO)(TMP)]·DMF (3) (dppb = 1,4-bis(diphenylphosphino)butane, PPH = triphenylphosphine and TMP = trimethoprim) were evaluated.

Leishmaniasis is a neglected disease that affects millions of individuals around the world. Regardless of clinical form, treatment is based primarily on the use of pentavalent antimonials. However, such treatments are prolonged and present intense side effects, which lead to patient abandonment in many cases.

Cytotoxic analyses were performed against murine tumors (Sarcoma 180 and B-16/F-10 cells) and peripheral blood mononuclear cells (PBMC) using MTT and Alamar Blue assays. Following, the investigation of cytotoxicity was executed by flow cytometry analysis and antitumoral and toxicological potential by in vivo techniques.

The proliferation inhibitors tested against tumour cell lines identified the derivatives tyrosine (4f) and lysine (4 g) as the most active among them, presenting IC(50) values in micromolar range and are more active than Safrole. For the study on the embryonic development, Safrole did not show any selectivity in this latter assay, which indicates that Safrole acts as a 'cell cycle-nonspecific' inhibitory agent.
