Modeling Dihydrofolate Reductase

The FASEB Journal, 2010
Dihydrofolate reductase (DHFR) is a ubiquitous enzyme that catalyzes the reduction of dihydrofolate (DHF) to tetrahydrofolate (THF). THF is crucial for purine and thymidylate synthesis, precursors to DNA and RNA. Inhibition of DHFR leads to cessation of cell proliferation because the cell

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.

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.

Green Synthesis of ZnO Nanoparticles From Spirulina platensis: Antimicrobial and Cytotoxic Evaluation With Molecular Docking Studies

ChemistryOpen, EarlyView.
Algal‐extract‐derived ZnO nanoparticles show shape anisotropy and are bio capped by phytochemicals. These green‐synthesized NPs strongly inhibit S. aureus and K. pneumoniae biofilms. Molecular docking suggests stable binding of surface biomolecules to microbial targets, highlighting synergistic antibacterial mechanisms.

Xanthatin‐13‐(Pyrrolidine‐2‐Carboxylic Acid), a Sesquiterpene Lactone Isolated From Burdock Leaf, Attenuated Aβ25‐35 Toxicity and Memory Deficits in a Pharmacological Mouse Model of Alzheimer's Disease

Phytotherapy Research, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a severe form of dementia, which occurrence increases with age and lifestyle conditions. It is characterized by amyloid protein accumulation forming senile plaques, hyperphosphorylated tau protein forming neurofibrillary tangles, neuroinflammation, and oxidative stress, leading to synapse loss and cell death ...

CoMFA and CoMSIA Analyses of Pneumocystis carinii Dihydrofolate Reductase, Toxoplasma gondii Dihydrofolate Reductase, and Rat Liver Dihydrofolate Reductase [PDF]

Journal of Medicinal Chemistry, 2005
In a continuing effort to develop potent and selective dihydrofolate reductase (DHFR) inhibitors against opportunistic pathogens, we developed three-dimensional quantitative structure-activity relationship (3D QSAR) models for the inhibitory activity against Pneumocystis carinii (pc) DHFR, Toxoplasma gondii (tg) DHFR, and rat liver DHFR, using a data ...

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...
