A vaccine against the Chagas disease, capable of stimulating the immune response against the trans-sialidase virulence factor of the Trypanosoma cruzi parasite, which is a multicomponent vaccine comprising: (a) an immunogenic portion formed by one or more recombinant or synthetic polypeptides or fractions of thereof and (b) one or more polynucleotides including the regions codifying one or more immunogenic polypeptides, or a monocomponent vaccine comprising at least one component selected among an immunogenic portion formed by one or more recombinant or synthetic polypeptides or fractions of them and a group of polynucleotides including the regions codifying one or more immunogenic polypeptides derived from Trypanosoma cruzi and pharmaceutical compositions containing said multicomponent and monocomponent vaccines, the procedures for obtaining the immunogen portion of said vaccines and the nucleic acid used in the procedure.

The present invention relates to thio semicarbazone and semicarbazone inhibitors of cysteine proteases and methods of using such compounds to prevent and treat protozoan infections such as trypanosomiasis, malaria and leishmaniasis. The compounds also find use in inhibiting cysteine proteases associated with carcinogenesis, including cathepsins B and L.

The invention provides a method of enhancing the efficacy of antibiotic treatment of tuberculosis, trypanosomiasis, leprosy, and leishmaniasis involving co-administering to a mammal undergoing antibiotic treatment therapeutically effective amounts of a first compound that is an inhibitor of 5-lipoxygenase and optionally a second compound that is a product of the cyclooxygenase pathways. The invention also provides a pharmaceutical composition comprising an antibiotic, an inhibitor of 5-lipoxygenase, and a product of the cyclooxygenase pathways.

Methods are provided to inhibit proliferation of Trypanosoma cruzi with imido-substituted 1,4-naphthoquinones, including novel compounds. Administering an imido-substituted 1,4-naphthoquinone can be used to provide prophylaxis or treatment to a patient in need of treatment against Chagas disease.

The present invention relates to a synthetic immunogen represented by the general formula 1, useful for generating long lasting protective immunity against various intracellular pathogens which are the causative agents of tuberculosis, leishmaniasis, AIDS, trypanosomiasis, malaria and also allergy, cancer and a process for the preparation thereof. The developed immunogen is able to circumvent HLA restriction in humans and livestock. The invention further relates to a vaccine comprising the said immunogen for generating enduring protective immunity against various diseases. The said vaccine is targeted against intracellular pathogens, more particularly the pathogen M. tuberculosis in this case. In the present invention, promiscuous peptides of M. tuberculosis are conjugated to TLR ligands especially; Pam2Cys to target them mainly to dendritic cells and therefore elicit long-lasting protective immunity.wherein, X1=a promiscuous CD4 T helper epitope selected from SEQ ID No. 1 to 98 OR nil;X2=a promiscuous CD8 T cytotoxic epitope selected from SEQ ID No. 99 to 103 OR nil;when X1=nil; X2=SEQ ID No. 99 to 103 and when X2=nil; X1=SEQ ID No. 1 to 98;Y=Lysine; andS=Serine.
