Why the study?

Morin's broad neuroprotective, anti-inflammatory, and antioxidant effects across diverse neurodegenerative and neurotoxic models require consolidation to evaluate its consistent benefits and mechanisms.

Does morin improve survival, motor/cognitive performance, and biochemical normalization in in vitro and rodent models of neurotoxicity and neurodegeneration?

Population

In vitro and rodent models of neurodegenerative proteinopathies, neuropathic pain, epilepsy, stress- and schizophrenia-like phenotypes, and neurotoxicity

Comparison

Morin exposure vs no morin or control conditions

Design

Review of preclinical in vitro and rodent studies

Key result

Morin emerges as a multitarget neuroprotective scaffold with reproducible functional and mechanistic benefits across in vitro and rodent models of neurodegeneration and neurotoxicity.

Overview

Morin shows consistent preclinical neuroprotection; leaves open clinical translation and requires human trials before any therapeutic consideration.

Key Points

  • To synthesize preclinical evidence evaluating the neuroprotective, antioxidant, and anti-inflammatory mechanisms of morin across models of neurotoxicity and neurodegenerative diseases.
  • Consolidated evidence from in vitro assays and rodent models covering proteinopathies (Alzheimer's, Parkinson's, Huntington's), toxicant exposures (chemotherapeutics, heavy metals, acrylamide), epilepsy, and neuropathic pain.
  • Evaluated functional behavioral outcomes alongside molecular assays targeting mitochondrial function, redox balance, innate immune signaling, and programmed cell death.
  • Morin consistently improved survival and motor and cognitive performance while mitigating neurotoxicity induced by chemotherapeutics, heavy metals, and endocrine disruptors.
  • Restored redox and mitochondrial homeostasis via Nrf2/HO-1 upregulation, replenishing SOD, catalase, and glutathione while decreasing reactive oxygen species, malondialdehyde, and nitric oxide.
  • Downregulated TLR4/NF-κB and NLRP3 inflammasome activation, reduced proinflammatory cytokines (TNF-α, IL-1β, IL-6), and rebalanced cell-death cascades by reducing Bax/caspase-3 and attenuating RIPK1/RIPK3/MLKL-mediated necroptosis.

Morin is a multitarget neuroprotective scaffold with reproducible functional and mechanistic benefits in preclinical models, warranting further translational research.

Limitations

  • Lack of rigorously controlled clinical trials
  • Need for optimized delivery and pharmacokinetic-pharmacodynamic mapping
  • Need for target engagement biomarkers to define dose, route, and indications
  • Lack of optimized delivery
  • Lack of pharmacokinetic-pharmacodynamic mapping
