Calcium Modulating Effect of Polycyclic Cages: A Suitable Therapeutic Approach Against Excitotoxic-induced...

Area of Science:

• Neuroscience
• Pharmacology
• Biochemistry

Background:

• Neurodegenerative disorders present a significant global health challenge, driven by progressive neuronal cell loss.
• Excitotoxicity, a process involving calcium overload, is a key factor in the pathology of these conditions.
• Calcium dysregulation is central to neurodegeneration, necessitating therapeutic interventions targeting calcium homeostasis.

Purpose of the Study:

• To review the role of calcium dysregulation in neurodegenerative disorders.
• To explore polycyclic cage compounds as potential therapeutic agents for neuroprotection.
• To discuss the structure-activity relationships and neuroprotective mechanisms of these compounds.

Main Methods:

• Literature review focusing on calcium dysregulation in neurodegeneration.
• Analysis of studies on polycyclic cage compounds, including NGP1-01.
• Examination of structure-activity relationships and neuroprotective effects (e.g., free radical scavenging, anti-neuroinflammation).

Main Results:

• Polycyclic cage compounds, structurally similar to amantadine and memantine, can attenuate calcium influx.
• NGP1-01 effectively inhibits N-methyl-D-aspartate (NMDA) receptors and voltage-gated calcium channels (VGCCs).
• These compounds exhibit broad neuroprotective properties, including antioxidant and anti-inflammatory effects.

Conclusions:

• Polycyclic cage compounds represent a promising therapeutic strategy for neurodegenerative diseases by targeting calcium dysregulation.
• Further research, including clinical trials, is essential to establish the safety and efficacy of these compounds beyond amantadine and memantine.
• The multifunctional nature of polycyclic cages offers potential for treating complex neurodegenerative conditions.
