Euquinine

Euquinine (CAS No.: 83-75-0) is a quinine derived small molecule salt form used as a research reagent in parasitology and anti infective discovery, primarily positioned as a quinoline alkaloid related tool compound for studies of Plasmodium falciparum biology, multidrug resistance phenotypes, and comparative bioavailability behavior versus parent quinine like scaffolds in preclinical systems. Based on the established pharmacological lineage of quinine class antiplasmodial agents, its functional background in biomedical research is associated with interference in parasite heme detoxification processes during intraerythrocytic stages, with downstream disruption of parasite survival programs and stress response homeostasis, while precise target level assignment for Euquinine itself remains insufficiently resolved and is therefore generally interpreted through class consistent mechanisms rather than a uniquely validated molecular target profile. In vitro activity is commonly described at nanomolar to micromolar or low micromolar levels in susceptible versus resistant parasite assay contexts depending on strain background, exposure duration, and readout platform, and it is frequently incorporated into resistance reversal, cross sensitivity, and combination screening workflows to benchmark quinoline response patterns. Typical use cases include cell based malaria parasite culture assays, exploratory pharmacology in animal infection models, and medicinal chemistry or formulation oriented studies focused on exposure response relationships, where the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
