Investigation of Calcium Channel Blockers as Antiprotozoal Agents and Their Interference in the Metabolism of Leishmania (L.) infantum.

Evidence-based complementary and alternative medicine : eCAM

Reimão JQ, Mesquita JT, Ferreira DD, Tempone AG.
PMID: 26941821
Evid Based Complement Alternat Med. 2016;2016:1523691. doi: 10.1155/2016/1523691. Epub 2016 Jan 28.

Leishmaniasis and Chagas disease are neglected parasitic diseases endemic in developing countries; efforts to find new therapies remain a priority. Calcium channel blockers (CCBs) are drugs in clinical use for hypertension and other heart pathologies. Based on previous reports...

Transport proteins determine drug sensitivity and resistance in a protozoan parasite, Trypanosoma brucei.

Frontiers in pharmacology

Munday JC, Settimo L, de Koning HP.
PMID: 25814953
Front Pharmacol. 2015 Mar 09;6:32. doi: 10.3389/fphar.2015.00032. eCollection 2015.

Drug resistance in pathogenic protozoa is very often caused by changes to the 'transportome' of the parasites. In Trypanosoma brucei, several transporters have been implicated in uptake of the main classes of drugs, diamidines and melaminophenyl arsenicals. The resistance...

Pentamidine, an FDA-approved antiparasitic drug, was recently identified as an outer membrane disrupting synergist that potentiates erythromycin, rifampicin, and novobiocin against Gram-negative bacteria. The same study also described a preliminary structure-activity relationship using commercially available pentamidine analogues. We here...
