QUINACRINE

Product Description

Mechanism of Action

QUINACRINE (ID 27313) demonstrates an exceptionally broad biochemical influence profile integrating multi‑axis signalling interference, deep enzymatic cascade modulation, mitochondrial‑network reprogramming, ion‑flux recalibration, structural‑protein remodelling, and transcription‑factor pathway redistribution. Its conformational flexibility enables high‑affinity docking to catalytic residues, regulatory allosteric sites, transmembrane helices, scaffolding complexes, and cytoskeletal polymers. This results in cross‑system modulation spanning metabolic, structural, genomic and stress‑adaptive biological layers.

Mechanistically, the compound can perturb phosphorylation landscapes, alter propagation velocity across MAPK, JNK, ERK, p38 and PI3K–AKT pathways, shift G‑protein signalling bias, redistribute intracellular Ca²⁺ waveforms, modulate cAMP–PKA activity, and influence mitochondrial ROS leakage thresholds. Secondary messenger amplification, membrane‑potential polarity adjustments and ATP/ADP cycle reshaping are frequently observed across experimental substrates.

Advanced Research Applications

QUINACRINE is applied in high‑precision laboratory environments for:

• Deep kinome‑mapping and cross‑cascade interference modelling
• Receptor–ligand structural docking with meta‑stability prediction
• Organelle‑stress analysis including UPR, ER stress, mitochondrial oxidative load and mitophagy balance
• Multi‑omics transcriptome reconstruction with clustering of regulatory subnetworks
• High‑resolution cytoskeletal dynamics mapping (actin tension, tubulin flux, scaffold integrity)
• Cell‑fate modelling across apoptosis, necroptosis, ferroptosis and autophagic flux states
• AI‑driven SAR/QSAR modelling for compound performance optimisation

Toxicodynamics & Hazard Spectrum

At elevated or prolonged exposure, expected risks include:

• Acute ROS escalation with collapse of antioxidant buffering systems
• Mitochondrial fragmentation or electron‑transport chain impairment
• Severe Ca²⁺/Na⁺/K⁺ ion‑channel dysregulation
• Cytoskeletal depolymerisation causing mechanical instability
• Membrane rupture or lipid‑bilayer thinning
• Hyperactivation of inflammatory signalling (NF‑κB, STAT families, IRF genes)
• Activation of programmed‑cell‑death pathways on multiple axes
• Epigenetic perturbation including methylation drift and histone‑mark imbalance
