Structures of Plasmodium falciparum Chloroquine Resistance Transporter (PfCRT) Isoforms and Their Interactions with Chloroquine

Biochemistry, 2023
Using a recently elucidated atomic-resolution cryogenic electron microscopy (cryo-EM) structure for the Plasmodium falciparum chloroquine resistance transporter (PfCRT) protein 7G8 isoform as template [Kim, J.; Nature 2019, 576, 315-320], we use Monte Carlo molecular dynamics (MC/MD) simulations of PfCRT embedded in a 1-palmitoyl-2-oleoyl-sn-glycero-3 ...

Sequence analysis of coding DNA fragments of pfcrt and pfmdr-1 genes in Plasmodium falciparum isolates from Odisha, India

Memorias do Instituto Oswaldo Cruz, 2011
The global emergence and spread of malaria parasites resistant to antimalarial drugs is the major problem in malaria control. The genetic basis of the parasite's resistance to the antimalarial drug chloroquine (CQ) is well-documented, allowing for the ...

A thirteen-year analysis of Plasmodium falciparum populations reveals high conservation of the mutant pfcrt haplotype despite the withdrawal of chloroquine from national treatment guidelines in Gabon

Malaria Journal, 2011
Background Chloroquine resistance (CR) decreased after the removal of chloroquine from national treatment guidelines in Malawi, Kenia and Tanzania. In this investigation the prevalence of the chloroquine resistance (CQR) conferring mutant pfcrt allele ...

Malaria in Bangladesh, 2000–2025: Navigating the Headwinds From Control to Elimination

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims Bangladesh has dramatically reduced its malaria burden since 2000, confining the disease to specific geographic zones. However, the national 2030 elimination goal is now threatened by a complex interplay of biological, ecological, and social factors.

Efficacy of artemether-lumefantrine for treating uncomplicated Plasmodium falciparum cases and molecular surveillance of drug resistance genes in Western Myanmar

Malaria Journal, 2020
Background Currently, artemisinin-based combination therapy (ACT) is the first-line anti-malarial treatment in malaria-endemic areas. However, resistance in Plasmodium falciparum to artemisinin-based combinations emerging in the Greater Mekong Sub-region

Evaluations of candidate markers of dihydroartemisinin-piperaquine resistance in Plasmodium falciparum isolates from the China–Myanmar, Thailand–Myanmar, and Thailand–Cambodia borders

Parasites & Vectors, 2022
Background The fast-declining clinical efficacy of dihydroartemisinin-piperaquine (DHA-PPQ) in Cambodia is a warning of the underlying westward dissemination of piperaquine resistance in the Greater Mekong Subregion (GMS).

Tailored for swift recognition: A structural perspective on secondary active plant hormone transporters

The Plant Journal, Volume 125, Issue 5, March 2026.
Significance Statement This review synthesizes current knowledge of plant hormone transporters across five major protein superfamilies. It links structural classification to transport mechanism and substrate specificity and demonstrates that this structural perspective provides a predictive framework for understanding substrate scope, selectivity ...

Small Molecule Kinase Inhibitors with In Vitro β‐Hematin Formation and Plasmodium falciparum Protein Kinase G Inhibitory Activity Identified Using Machine Learning

ChemMedChem, Volume 21, Issue 3, 12 February 2026.
A random forest machine learning model was used in combination with molecular docking to predict activity of small molecule kinase inhibitors against two crucial antimalarial targets, namely hemozoin crystallization and Plasmodium falciparum protein kinase G. Derazantinib shows most promise as a dual inhibitor.

Molecular Markers of Antimalarial Drug Resistance in Plasmodium falciparum From Kumasi, Ghana, 2023

Tropical Medicine &International Health, Volume 31, Issue 1, Page 43-48, January 2026.
ABSTRACT Objectives Artemisinin partial resistance has emerged in East Africa and is feared to spread across the continent, potentially compromising artemisinin‐based combination treatment. Molecular markers can serve as early warning signals for the development of specific drug resistance.
