Combination therapy for the treatment of visceral leishmaniasis has increasingly been advocated as a way to increase treatment efficacy and tolerance, to reduce treatment duration and cost, and to limit the emergence of drug resistance. In the present work, we have adopted a rational approach, which can modulate the immune response to overcome the negative(More)
Visceral leishmaniasis (VL) caused by the parasite Leishmania donovani, is a potentially fatal disease. It is characterized by prolonged fever, enlarged spleen and liver, substantial weight loss and progressive anemia. Available drugs are toxic, costly and require prolonged treatment duration viz; 28 days of oral treatment with miltefosine, 30 days infusion(More)
OBJECTIVES To evaluate the combination of CpG oligodeoxynucleotide (CpG ODN) and miltefosine for the treatment of experimental visceral leishmaniasis (VL). METHODS The experiments were carried out using BALB/c mice and hamsters, infected with Leishmania donovani. CpG ODN was administered at various doses by the intraperitoneal (ip) route. The dose of CpG(More)
The chemotherapy of visceral leishmaniasis (VL) has several limitations including resistance and toxicity of the existing drugs. Downregulation of immune system further aggravates the problems. To combat this situation, leishmanicidal efficacy of already marketed standard antifungal drug, fluconazole under the approach of “therapeutic switching” in(More)
Current drugs for the treatment of visceral leishmaniasis are inadequate, and their efficacies are also compromised due to suppression of immune function during the course of infection. Miltefosine is the only promising orally active antileishmanial drug, but due to its long half-life, there is risk of development of resistance. To overcome these problems,(More)
Antileishmanial activities of 16 synthetic oximino benzocycloalkyl azoles against Leishmania donovani were evaluated in vitro against extracellular promastigotes and intracellular amastigotes. Based on SI (Selectivity Index), five compounds were tested further in vivo in hamster model. Out of these, three compounds have shown medium activity (53-58%) and(More)
A series of 1-phenyl-4-glycosyl-dihydropyridines (4-17 and 19-21) were prepared by the one pot multicomponent reaction of glcosyl aldehyde, beta-keto compounds and aniline or substituted aniline in the presence of TBAHS as catalyst. The compounds were screened in vitro and in vivo for their antileishmanial activities. Most of the compounds exhibited(More)
Existing drugs for visceral leishmaniasis (VL) are partially effective, toxic, having high cost and long term treatment. Their efficacies are also compromised due to suppression of immune function associated during the course of infection. Combination therapy including a potential and safe immunostimulant with lower doses of effective drug has proven as a(More)
In view of the severe immunosuppression in visceral leishmaniasis (VL), a rational approach to effectively combat the parasitic scourge would be to enhance the immune status of the host. Use of CpG oligodeoxynucleotide (CpG-ODN) against leishmaniasis has previously been reported, especially as an immunomodulator and adjuvant with various immunogens. In the(More)
Prophylactic potential of synthetic bacterial lipopeptide and a TLR2 agonist, Pam3Cys was first evaluated against experimental visceral leishmaniasis in rodent model. After establishing the potential its effect on therapeutic efficacy of miltefosine was also studied. Pam3Cys showed 74.64% inhibition in parasitic establishment when administered by ip route(More)
