Dihydrofolate Reductase Inhibitors: The Pharmacophore as a Guide for Co-Crystal Screening

Molecules, 2021
In this work, co-crystal screening was carried out for two important dihydrofolate reductase (DHFR) inhibitors, trimethoprim (TMP) and pyrimethamine (PMA), and for 2,4-diaminopyrimidine (DAP), which is the pharmacophore of these active pharmaceutical ...

Pioneer Use of Antimalarial Transdermal Combination Therapy in Rodent Malaria Model

Pathogens, 2023
We have previously reported 1,2,6,7-tetraoxaspiro [7.11]nonadecane (N-89) as a promising antimalarial compound. In this study, we evaluated the effect of transdermal therapy (tdt) of N-89 in combination (tdct) with other antimalarials as an application ...

Suppressing STAT3 activity protects the endothelial barrier from VEGF-mediated vascular permeability

Disease Models & Mechanisms, 2021
Vascular permeability triggered by inflammation or ischemia promotes edema, exacerbates disease progression and impairs tissue recovery. Vascular endothelial growth factor (VEGF) is a potent inducer of vascular permeability.

Anticancer Activity of Pyrimethamine via Ubiquitin Mediated Degradation of AIMP2-DX2

Molecules, 2020
While aminoacyl-tRNA synthetase-interacting multifunctional protein 2 (AIMP2) is a tumor suppressor, its exon 2-depleted splice variant (AIMP2-DX2 or shortly DX2) is highly expressed in human lung cancer, and the ratio of DX2 to AIMP2 increases according

Understanding the Pyrimethamine Drug Resistance Mechanism via Combined Molecular Dynamics and Dynamic Residue Network Analysis

Molecules, 2020
In this era of precision medicine, insights into the resistance mechanism of drugs are integral for the development of potent therapeutics. Here, we sought to understand the contribution of four point mutations (N51I, C59R, S108N, and I164L) within the ...
