1. OTIMIZAÇÃO E VALIDAÇÃO DE MÉTODO ENZIMÁTICO SEMIQUANTITATIVO SIMPLES E DE BAIXO CUSTO PARA A BUSCA DE INIBIDORES DE CISTEINO PROTEASES
Cysteine proteases are an important class of enzymes involved in several essential biological processes. For this reason, these enzymes are important therapeutic targets, and therefore can be used in enzymatic assays for the search of hits. The most widely used methods in the search of enzyme inhibitors are spectrophotometric, however they have relatively hi

2. Proteome of fraction from Tityus serrulatus venom reveals new enzymes and toxins
Abstract Background: Tityus serrulatus venom (Ts venom) is a complex mixture of several compounds with biotechnological and therapeutical potentials, which highlights the importance of the identification and characterization of these components. Although a considerable number of studies have been dedicated to the characterization of this complex cocktail, t

3. Purification and enzymatic characterization of a novel metalloprotease from Lachesis muta rhombeata snake venom
Abstract Background: Lachesis muta rhombeata (Lmr) is the largest venomous snake in Latin America and its venom contains mainly enzymatic components, such as serine and metalloproteases, L-amino acid oxidase and phospholipases A2. Metalloproteases comprise a large group of zinc-dependent proteases that cleave basement membrane components such as fibronectin

4. Design, Synthesis, Biological Evaluation and Molecular Modeling Studies of Novel Eugenol Esters as Leishmanicidal Agents
Leishmaniasis is a neglected pathology with a high incidence worldwide, and is a governmental health issue due to the increased morbidity and mortality associated with the disease and a scarce therapeutic arsenal. Cysteine proteases have been investigated as targets for new drugs because they are essential in the infectivity of the parasite during its intera

5. An in silico Study of Benzophenone Derivatives as Potential Non-Competitive Inhibitors of Trypanosoma cruzi and Leishmania Amazonensis Cysteine Proteinases
This study investigates the mechanisms of interaction between benzophenone derivatives and cruzain and Llacys1 (the protein expressed by cysteine protease gene isoform 1 of L. amazonensis) by homology modelling, docking and molecular dynamics simulation. The results predict that the same binding site in cruzain and Llacys1 is involved in complexes with benzo

6. Plant senescence and proteolysis: two processes with one destiny
Abstract Senescence-associated proteolysis in plants is a complex and controlled process, essential for mobilization of nutrients from old or stressed tissues, mainly leaves, to growing or sink organs. Protein breakdown in senescing leaves involves many plastidial and nuclear proteases, regulators, different subcellular locations and dynamic protein traffic

7. l-Amino acid oxidase isolated from Calloselasma rhodostoma snake venom induces cytotoxicity and apoptosis in JAK2V617F-positive cell lines
ABSTRACT BACKGROUND: Myeloproliferative neoplasms are Philadelphia chromosome-negative diseases characterized by hyperproliferation of mature myeloid cells, associated or not with the Janus kinase 2 tyrosine kinase mutation, JAK2V617F. As there is no curative therapy, researchers have been investigating new drugs to treat myeloproliferative neoplasms, incl

8. Streptozotocin-induced diabetes mellitus affects lysosomal enzymes in rat liver
It has been previously shown that dextran sulfate administered to diabetic rats accumulates in the liver and kidney, and this could be due to a malfunction of the lysosomal digestive pathway. The aim of the present study was to evaluate the expression and activities of lysosomal enzymes that act upon proteins and sulfated polysaccharides in the livers of dia

9. Kaurene diterpene induces apoptosis in U87 human malignant glioblastoma cells by suppression of anti-apoptotic signals and activation of cysteine proteases
Gliomas are the most common and malignant primary brain tumors in humans. Studies have shown that classes of kaurene diterpene have anti-tumor activity related to their ability to induce apoptosis. We investigated the response of the human glioblastoma cell line U87 to treatment with ent-kaur-16-en-19-oic acid (kaurenoic acid, KA). We analyzed cell survival

10. Síntese e avaliação de compostos de selênio(IV) e telúrio(IV) como inibidores de cisteíno e treonino proteases / Synthesis and evaluation of selenium(IV) and tellurium(IV) compounds as cysteine and threonine proteases inhibitors
Neste trabalho está descrito a síntese e avaliação biológica de uma série de compostos de selênio(IV) e telúrio(IV). Esta série foi planejada para que diferentes fatores estruturais pudessem ser avaliados e as possíveis relações entre a estrutura e atividade biológica dos compostos pudessem ser determinadas. Para tanto, selênio, telúrio, cloro

11. Theobroma cacao cystatins impair Moniliophthora perniciosa mycelial growth and are involved in postponing cell death symptoms.
Three cystatin open reading frames named TcCys1, TcCys2 and TcCys3 were identified in cDNA libraries from compatible interactions between Theobroma cacao (cacao) and Moniliophthora perniciosa. In addition, an ORF named TcCys4 was identified in the cDNA library of the incompatible interaction. The cDNAs encoded conceptual proteins with 209, 127, 124, and 205

12. Utilização do inibidor de papaína extraído de sementes de Adenanthera pavonina L. na purificação de proteases cisteínicas / Using the inhibitor of papain extracted from seeds of Adenanthera pavonina L. in the purification of cysteine proteases
No presente trabalho um inibidor de papaína extraído de sementes de A. pavonina foi imobilizado por ligação covalente em polianilina (PANI) modificada com glutaraldeído (PANIG), visando a aplicação desse material como fase estacionária para cromatografia de afinidade e sua aplicação na purificação das proteases cisteínicas bromelaína e ficina.
