Parasitic diseases are still a major health problem in developing countries. In our effort to find new antiparasitic agents, in this Letter we report the in vitro antiprotozoal activity of omeprazole, lansoprazole, rabeprazole and pantoprazole against Trichomonas vaginalis, Giardia intestinalis and Entamoeba histolytica. Molecular modeling studies were an(More)
Benzimidazole-2-carbamate derivatives (BzCs) are the most commonly used antiparasitic drugs for the treatment of protozoan and helminthic infections. BzCs inhibit the microtubule polymerization mechanism through binding selectively to the β-tubulin subunit in which mutations have been identified that lead to drug resistance. Currently, the lack of(More)
Synaptic vesicle protein 2A (SV2A) is an integral membrane protein necessary for the proper function of the central nervous system and is associated to the physiopathology of epilepsy. SV2A is the molecular target of the anti-epileptic drug levetiracetam and its racetam analogs. The racetam binding site in SV2A and the non-covalent interactions between(More)
Cytochrome P4501A1 is involved in the metabolism of carcinogenic polycyclic aromatic hydrocarbons; therefore, its inhibition interferes with the carcinogenesis process induced by these compounds in rats. The human and rat CYP1A1 differ by 21% in amino acid sequence, including the active site of the enzyme; this difference may be an important factor when(More)
To develop a new set of compounds with inhibitory activity against the triosephosphate isomerase of Trypanosoma cruzi (TcTIM), a group of benzimidazole derivatives was studied using four different docking procedures. These docking procedures differ in the number and type of mobile residues considered in the analysis. As a result of this methodology, a(More)
Thirty-three meso-dihydroguaiaretic acid (meso-DGA) derivatives bearing esters, ethers, and amino-ethers were synthesized. All derivatives were tested against twelve drug-resistant clinical isolates of Gram-positive and Gram-negative bacteria, including sensitive (H37Rv) and multidrug-resistant Mycobacterium tuberculosis strains. Among the tested compounds,(More)
The AKT isoforms are a group of key kinases that play a critical role in tumorigenesis. These enzymes are overexpressed in different types of cancers, such as breast, colon, prostate, ovarian, and lung. Because of its relevance the AKT isoforms are attractive targets for the design of anticancer molecules. However, it has been found that AKT1 and AKT3(More)
The present research aimed to isolate the non-polar secondary metabolites that produce the vasodilator effects induced by the dichloromethane extract of Prunus serotina (P. serotina) fruits and to determine whether the NO/cGMP and the H2S/KATP channel pathways are involved in their mechanism of action. A bioactivity-directed fractionation of the(More)
Cysteine proteases from parasites as well as from mammals are promising drug targets for parasitic infections and systemic human diseases, respectively. Many reversible and irreversible inhibitors of this very large class of proteins have been designed. Among others, molecules with a nitrile moiety, which is a group that is susceptible to a nucleophilic(More)
