Foundations of AI in NP Chemistry
The foundation of artificial intelligence applications in neuroprotective NP discovery rests upon datasets that capture both chemical structures and biological activities. These repositories provide the essential training data for machine learning models while enabling representation learning approaches that translate molecular structures into formats suitable for computational analysis. NPs present unique challenges for data representation due to their stereochemical complexity, diverse functional groups, and scaffolds that differ substantially from synthetic compounds.
Recent reviews have highlighted the potential of combining such chemical and biological data with AI-driven analytics to accelerate neuroprotective drug discovery. In particular, the authors of [137] critically review the neuroprotective effects of NPs derived from plants, marine organisms, and fungi in NDDs, emphasising mechanisms such as antioxidant, anti-inflammatory, and mitochondrial protective effects, while noting that challenges like bioavailability and the need for clinical validation can be addressed through AI-based modelling.
AI Models for Bioactivity & Target Prediction
Machine learning models have transformed the prediction of NP bioactivities and molecular targets, providing essential tools for identifying neuroprotective candidates that modulate key pathological mechanisms in NDDs. These computational approaches address fundamental challenges in NP research, including the need to predict activities against multiple targets simultaneously, understand complex structure-activity relationships, and prioritise compounds for experimental validation from vast chemical libraries [151,152].
Graph neural networks (GNNs) have emerged as particularly powerful tools for NP bioactivity prediction, representing molecules as mathematical graphs where atoms form nodes and chemical bonds create edges [153]. This representation preserves the complete molecular topology while enabling learned features that capture complex structural patterns. The study proposed in [154] introduces a novel chain-aware GNN that improves molecular property prediction by specifically capturing chain structures and long-range dependencies within molecular graphs, addressing the limitations of conventional GNNs like feature squashing.
Generative AI & Analogue Optimisation
Generative artificial intelligence has revolutionised the design and optimisation of NP analogues, creating novel molecules that retain beneficial neuroprotective properties while addressing limitations such as poor bioavailability, metabolic instability, or synthetic complexity. These approaches expand the accessible chemical space beyond naturally occurring structures while preserving the privileged scaffolds that have evolved over millions of years to interact with biological systems [164].
Variational autoencoders represent one of the most successful generative approaches for NP analogue design. These models learn compressed representations of molecular structures in a continuous latent space, enabling smooth interpolation between different NPs and the generation of novel structures with desired properties. In neuroprotective applications, chemical variational autoencoders have been employed to expand the diversity of natural product-like inhibitors targeting key AD pathways [164].
Systems Pharmacology & Multi-Omics
Systems pharmacology approaches recognise that NPs function as multi-target modulators within complex biological networks rather than acting on single molecular targets in isolation. This perspective aligns naturally with the polypharmacological nature of many neuroprotective NPs, which often simultaneously modulate oxidative stress, neuroinflammation, protein aggregation, and cell survival pathways.
Integration of graph-based methods and multi-omics data provides unprecedented insights into how NPs influence the interconnected molecular networks disrupted in NDDs [173]. Graph-based integration methods construct knowledge graphs that connect NPs to their molecular targets, biological pathways, and disease phenotypes. These representations enable sophisticated analyses that go beyond simple target-compound relationships to capture the full complexity of NP pharmacology.

AI-Guided Flavonoid Analogue Discovery for AD
Thai and colleagues employed machine learning models combined with atomistic simulations to screen natural compounds from the VIETHERB database for acetylcholinesterase (AChE) inhibition, successfully identifying twenty compounds with sub-nanomolar binding affinities (IC50 < 1 nM). This integrated approach demonstrated superior predictive accuracy compared to conventional virtual screening methods.
Key Takeaway: AI significantly accelerates the identification of highly potent NP-derived compounds for AD by combining predictive modeling with atomistic simulations.
