Antimalarial flavonoid glycoside from Carica papaya with inhibitory potential against Plasmodium falciparum dihydrofolate reductase thymidylate synthase: an in-silico study

Universa Medicina
BACKGROUND Carica papaya is traditionally used to treat malaria. The mechanism of action of the active constituents may be determined by molecular docking.

Precision Chemistry for Protein Lysine Modification

Chemistry – A European Journal, EarlyView.
Selective modification of lysine residues is challenging due to their similar intrinsic reactivity. Inspired by enzymatic recognition, ligand‐guided electrophiles enable site‐selective labeling and functionalization, while ligand‐guided catalyses achieve regioselective installation of bio‐relevant post‐translational modifications.

Metformin sensitises hepatocarcinoma cells to methotrexate by targeting dihydrofolate reductase

Cell Death and Disease, 2021
Metformin, the first-line drug for type II diabetes, has recently been considered an anticancer agent. However, the molecular target and underlying mechanism of metformin’s anti-cancer effects remain largely unclear.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Extraction of Antimicrobial Peptides From Fava Bean Protein Hydrolyzate by Phosphorylated Biochar

Food Safety and Health, EarlyView.
Antimicrobial peptides were extracted by functional biochar in one step. The enriched peptides demonstrated significantly enhanced antibacterial activity. ABSTRACT The extraction of antimicrobial peptides (AMPs) from plant proteins remains challenging due to their low abundance, structural diversity, and the need for mild, efficient, and selective ...

Timing of conception after methotrexate and subsequent pregnancy outcomes: A retrospective cohort study

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Methotrexate is widely used to treat ectopic pregnancy (EP). Concerns about its teratogenicity have led to uncertainty regarding the optimal interval before attempting conception. Guidelines recommend a 3‐month washout period, while the manufacturer advises 6 months. Evidence on the safety of early conception is limited.

Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

INHIBITORY ACTIVITY OF SOME MARINE SPONGE EXTRACTS FROM URABÁ GULF ON DIHYDROFOLATE REDUCTASE ENZYME

Vitae, 2009
Dihydrofolate reductase is an enzyme involved in the production of pyrimidinic base timidin, a structural component of DNA, therefore whatever substance that inhibit this enzyme inhibit the DNA synthesis as a consequence and it can be potentially useful ...
