Cellular targets of mefloquine

Area of Science:

• Pharmacology
• Toxicology
• Cell Biology

Background:

• Mefloquine is a quinoline-based antimalarial drug used for chemoprophylaxis.
• Despite its efficacy against Plasmodium, mefloquine's use is limited by its toxicity in humans.
• Research has elucidated mefloquine's anti-Plasmodium mechanisms but less is known about its cellular toxicity.

Purpose of the Study:

• To review the functional and mechanistic aspects of mefloquine's cytotoxic effects.
• To consolidate current knowledge on how mefloquine impacts human cells.
• To provide a comprehensive overview of mefloquine-induced cellular damage.

Main Methods:

• Literature review of studies on mefloquine's cellular effects.
• Analysis of research detailing mefloquine's interactions with cellular components.
• Synthesis of findings on downstream signaling pathways affected by mefloquine.

Main Results:

• Mefloquine targets cellular lipids, proteins, and complexes, disrupting signaling cascades.
• It induces various cellular dysfunctions including altered membrane potential, oxidative stress, and ion imbalance.
• These effects lead to metabolic disruption, organelle dysfunction, cell cycle arrest, and programmed cell death.

Conclusions:

• Mefloquine exhibits significant cytotoxicity by interfering with fundamental cellular processes.
• Understanding these mechanisms is crucial for mitigating mefloquine's adverse effects.
• Further research into mefloquine's toxicological profile is warranted to ensure patient safety.
