has a high level of active chemicals that are useful in the food industry, and they have antibacterial and food preservation properties. The characterization of seed oil (MOS) may vary due to agronomic and environmental factors. Therefore, it was necessary to know the composition of lipids present in our oil extracted under pressing at 180 °C and thus determine if it is suitable to produce a biopackaging.

Bacteria resistance to antibiotics is a concerning global health problem; in this context, methicillin-resistant (MRSA) is considered as a high priority by the World Health Organization. Furthermore, patients with a positive result for COVID-19 received early antibiotic treatment, a fact that potentially encourages the increase in antibiotic resistance. Therefore, there is an urgency to develop new drugs with molecular mechanisms different from those of the actual treatments.

Protein tyrosine phosphatase 1B (PTP1B) dephosphorylates phosphotyrosine residues and is an important regulator of several signaling pathways, such as insulin, leptin, and the ErbB signaling network, among others. Therefore, this enzyme is considered an attractive target to design new drugs against type 2 diabetes, obesity, and cancer. To date, a wide variety of PTP1B inhibitors that have been developed by experimental and computational approaches.

Leishmaniasis is a disease caused by parasites of the genus that affects 98 countries worldwide, 2 million of new cases occur each year and more than 350 million people are at risk. The use of the actual treatments is limited due to toxicity concerns and the apparition of resistance strains. Therefore, there is an urgent necessity to find new drugs for the treatment of this disease.

Methicillin-resistant (MRSA) is an important threat as it causes serious hospital and community acquired infections with deathly outcomes oftentimes, therefore, development of new treatments against this bacterium is a priority. Shikimate kinase, an enzyme in the shikimate pathway, is considered a good target for developing antimicrobial drugs; this is given because of its pathway, which is essential in bacteria whereas it is absent in mammals. In this work, a computer-assisted drug design strategy was used to report the first potentials inhibitors for Shikimate kinase from methicillin-resistant (SaSK), employing approximately 5 million compounds from ZINC15 database.

Protein-tyrosine phosphatase 1B (PTP1B) is a negative regulator of insulin signaling pathway and has been validated as a therapeutic target for type 2 diabetes. A wide variety of scaffolds have been included in the structure of PTP1B inhibitors, one of them is the benzimidazole nucleus. Here, we report the design and synthesis of a new series of di- and tri- substituted benzimidazole derivatives including their kinetic and structural characterization as PTP1B inhibitors and hypoglycemic activity.

In our study, we aimed to evaluate the effects of leaves extract on rat paraoxonase 1 (rPON1) and catalase (rCAT) activities in alloxan-induced diabetic rats. Our study included three groups; group C (control, n = 5); group D (diabetic, n = 5); and group DM ( extract-supplemented diabetic rats, n = 5). Daily oral administration of extract at 200 mg/kg doses produced an increase in endogenous antioxidants.

Due to its resistance to many antibiotics, methicillin-resistant Staphylococcus aureus (MRSA) have become a worldwide health problem creating the urgent necessity of developing new drugs against this pathogen. In this sense, one approach is to search for inhibitors of important enzymes in its metabolism. According to this, the shikimate pathway is an important metabolic route in bacteria and its enzymes are considered as great targets for the development of new antibiotic drugs.

One of the most widespread pathogens worldwide is methicillin-resistant Staphylococcus aureus, a bacterium that provokes severe life-threatening illnesses both in hospitals and in the community. The principal challenge lies in the resistance of MRSA to current treatments, which encourages the study of different molecular targets that could be used to develop new drugs against this infectious agent. With this goal, a detailed characterization of shikimate kinase from this microorganism (SaSK) is described.

Mitochondrial dysfunction is a hallmark of diabetes, but the metabolic alterations during early stages of the disease remain unknown. The ability of liver cells to rearrange their metabolism plays an important role in compensating the energy shortage and may provide cell survival. leaves have been studied for its health properties against diabetes, insulin resistance, and non-alcoholic liver disease.

The Atlas of Diabetes reports 415 million diabetics in the world, a number that has surpassed in half the expected time the twenty year projection. Type 2 diabetes is the most frequent form of the disease; it is characterized by a defect in the secretion of insulin and a resistance in its target organs. In the search for new antidiabetic drugs, one of the principal strategies consists in promoting the action of insulin.

Methicillin-resistant Staphylococcus auerus (MRSA) strains are having a major impact worldwide, and due to their resistance to all β-lactams, an urgent need for new drugs is emerging. In this regard, the shikimate pathway is considered to be one of the metabolic features of bacteria and is absent in humans. Therefore enzymes involved in this route, such as shikimate dehydrogenase (SDH), are considered excellent targets for discovery of novel antibacterial drugs.

Entamoeba histolytica, the parasite which causes amebiasis is responsible for 110,000 deaths a year. Entamoeba histolytica depends on glycolysis to obtain ATP for cellular work. According to metabolic flux studies, hexokinase exerts the highest flux control of this metabolic pathway; therefore, it is an excellent target in the search of new antiamebic drugs.

In the search of molecules that can serve as leads in the design of a new drug for the treatment of Chagas' disease, we found that some brevifolin carboxylate derivatives isolated from Geranium bellum Rose, inactivate triosephosphate isomerase from Trypanosoma cruzi (TcTIM) in a species-specific manner. After spectroscopic characterization, these compounds were identified as methylbrevifolin carboxylate (1), ethylbrevifolin carboxylate (2), butylbrevifolin carboxylate (3) and the methylated derivate methyl tri-O-methylbrevifolin carboxylate (4). The concentrations required to inactivate fifty percent the activity of TcTIM were 6.
