Azoles such as posaconazole (Posa) are highly potent against Trypanosoma cruzi . However, when tested in chronic Chagas disease patients, a high rate of relapse after Posa treatment was observed. It appears that inhibition T. cytochrome CYP51, the target azoles, does not deliver sterile cure monotherapy. Looking for suitable combination partners we have selected set inhibitors sterol and sphing...
We examined the protective effects of Mycobacterium bovis bacillus Calmette-Guérin (BCG) administration on Leishmania major infections of BALB/c and P/J mice. There were two treatment protocols. In the first, the footpads of naive animals were inoculated with mixtures of L. major and BCG (viable or heat killed) or the soluble mycobacterial antigen, purified protein derivative. Viable BCG, but n...
Development of new therapeutic approach to treat leishmaniasis has become a priority. In the present study, the antileishmanial effect of β-nitrostyrenes was investigated against in vitro promastigotes and amastigotes. A series of β-nitrostyrenes have been synthesized by using Henry reaction and were evaluated for their antimicrobial activities by broth microdilution assay and in vitro antileis...
We have refined a medium-throughput assay to screen hit compounds for activity against N-myristoylation in intracellular amastigotes of Leishmania donovani. Using clinically-relevant stages of wild type parasites and an Alamar blue-based detection method, parasite survival following drug treatment of infected macrophages is monitored after macrophage lysis and transformation of freed amastigote...
Leishmaniasis is a tropical parasitic infection. The resistance and toxicity issues are the major complications and remain significant consequences related to the treatment of leishmaniasis with the recent and classical drugs. Thus there is an immediate requirement to develop new compounds for the treatment of this protozoan disease. Sea cucumbers or holothurians are potentially presented as th...
Corresponding Authors: Tanmoy Bera Department of Pharmaceutical Technology, Jadavpur University, Kolkata700032, India. E-mail: [email protected], Phone: +91 9831470041, Tele Fax: +91 3324146677. Abstract: Backgrounds and objectives: Leishmania donovani is one of the most common species responsible for visceral leishmaniasis (VL) in India, Bangladesh and Sudan. The pentavalent antimonials...
Mutations within the polyamine biosynthetic pathway of Leishmania donovani, the etiological agent of visceral leishmaniasis, confer polyamine auxotrophy to the insect vector or promastigote form of the parasite. However, whether the infectious or amastigote form of the parasite requires an intact polyamine pathway has remained an open question. To address this issue, conditionally lethal Deltao...
objective(s):solanum acueastrum dunal.has been shown to have some chemotherapeutic value. leaf and berry water and methanol compounds of s. acueastrum were evaluated for possible antileishmanial activity in vivo on balb/c mice and in vitro against leishmania major promastigotes, amastigotes and vero cells. materials and methods: dry s. aculeastrum berry and leaf material were extracted in meth...
background: monoclonal antibodies have been employed extensively for the identification of leishmania species, development of diagnostic tests and in the characterization of defined leishmanial antigens. objectives: identification and characterization of leishmania spp. directly from cutaneous lesions of infected individuals. methods: an immunoperoxidase test (avidin-biotin technique) using mo...
OBJECTIVES This study was designed to verify the cytotoxic activity of S-nitrosoglutathione (GSNO) against intracellular Leishmania amastigotes and to test its efficacy as a topical treatment of localized cutaneous leishmaniasis (LCL) in Leishmania major- or Leishmania braziliensis-infected mice. METHODS Cytotoxic activity of GSNO was verified in L. major-infected THP-1 macrophages. S-nitrosa...
