Kinetoplast DNA: A Promising Drug Target for Treatment of Leishmaniasis
Leishmaniasis is a vector-borne zoonotic disease caused by various species of the genus Leishmania, (trypanosomatidae family) that is transmitted by phlebotomine sandflies. The disease can present in a range of clinical forms, including dermal lesions, metastasis mucocutaneous forms, and fatal visceral forms. In this non-systematic review, we aimed at introducing the role of kinetoplast DNA (kDNA) and dependent topoisomerases (TPI) as potential chemotherapeutic targets for treatment of leishmaniasis. The Leishmania parasite has a mitochondrial DNA located in the attached circles. KDNA replication process is very complex and a large number of proteins are involved. Some of them are classified as topoisomerases, which play major biological roles in the effective cell processes in the topology, synthesis, and organization of kDNA and constitute the main drug target in kinetoplast for leishmaniasis cure. Several studies have shown that the inhibitors of TPI exchange these enzymes into intracellular cell toxins and provide an appropriate tool for killing the parasite in the host. DNA binding drugs have also been reported as therapeutic agents against leishmanial infections.
A Mini-Review on Iron Chelating Agents as a Promising Therapeutic Target in Treatment of Leishmaniasis
There is a high prevalence of infections caused by Leishmania parasites and increasing rate of drug resistance. Lack of successful treatment with existing drugs calls for new therapeutic approaches. The main strategy in treatment of leishmaniasis is creating apoptosis and eliminating different forms of the parasite. So far, numerous drugs with specific mechanisms including 14-α-demethylase enzy...متن کامل
420 Thrombin-activatable fibrinolysis inhibitor (TAFI) is a 60kDa metallocarboxypeptidase produced by the liver and present in plasma. Independently discovered by several groups, the enzyme is also known as plasma procarboxypeptidase B, procarboxypeptidase R, or procarboxypeptidase U (1-5). TAFI as nomenclature was introduced by Bajar et al. (5). TAFI is expressed as a latent precursor requirin...متن کامل
The potential of PLGA-nanoparticles as a carrier of amphotericin B and doxorubicin against visceral leishmaniasis was evaluated by macrophage-mediated drug targeting approach. PLGA-nanoparticles were modified by coating them with macrophage-specific ligand-lectin. Prior to in-vitro studies, characterization studies were carried out systematically include particle size, surface morphology, perce...متن کامل

Widespread use of herbal drugs because of their protective effects on different organs toxicity has been shown in many studies. These protective effects have been illustrated in the fields of nephrotoxicity, hepatotoxicity, viral hepatitis, cancer, in vitro fertilization, neurotoxicity, depression, lung diseases, prostate diseases etc. Silymarin has cytoprotection activities due to its antioxid...متن کامل
The Formyl-peptide receptor-2 (FPR2) is a seven transmembrane G protein-coupled receptor, which plays an important role in sensing of bacteria and modulation of immune responses. FPR2 is also used by viruses for their own profit. Annexin A1, one of the multiple ligands of FPR2, is incorporated in the budding virus membrane of influenza A viruses (IAV). Thereby, once IAV infect a host cell, FPR2...متن کامل
