Ageing is associated with the decline in the capacity of the autophagy pathway to degrade dysfunctional and damaging cellular components, such as protein aggregates and mitochondria. Dysfunctional autophagy, in turn, undermines other cellular functions including DNA repair, metabolism and survival. Therefore, activation of autophagy is considered a promising therapeutic approach to combat ageing and age-related diseases. A large number of screens has been performed and published to date, these have identified a wide range of small molecules that stimulate initiation of autophagy. Prof. Korolchuck lab proposes to initiate a drug discovery program with the aim of identifying novel bioactive autophagy inducers.

Therapeutic Relevance
Early experimental results strongly support the hypothesis. Two novel autophagy-inducing targets (Autophagy1 confirmed, Autophagy2 hypothesized) have been identified, and the biological relevance is well-reinforced. VITA-FAST compounds induce autophagy at 10x the level of rapamycin. Three rounds of NCEs have been tested with three lead compounds showing 10-100x higher potency than earlier series. The mechanism of action — rescuing lysosomal dysfunction via autophagy activation — is validated across multiple cell models (Npc1-/-, Atg5-/-, Atg7-/-, FIP200/Rb1cc1-/-) with specificity controls demonstrating true autophagy-dependent rescue. Strong literature foundation from the Korolchuk Lab (H-index 56, 160+ publications) validates the autophagy-NAD axis across yeast, mouse, and human models. The only reason this is not a 5 is that formal EC50/IC50 values have not yet been reported and the second target (Autophagy2) remains at the hypothesis stage with the specific protein family member unconfirmed.
Therapeutic Optionality
Emerging findings clearly suggest multiple alternative applications beyond the primary NPC indication. The platform has broad applicability to longevity/aging, neurodegeneration (Alzheimer's, Parkinson's, Huntington's), other lysosomal storage disorders (Gaucher, Fabry, mucopolysaccharidoses), and metabolic diseases. Two lead repurposing molecules with prior Phase 1 data open a parallel clinical pathway. The identification of two novel targets that are 'previously proposed longevity targets' expands the therapeutic landscape. Combination approaches with NAD+ precursors and sirtuin activators have been identified. The dual development path (NCEs + drug repurposing via UAE) represents meaningful optionality. Scored 4 rather than 5 because these alternative pathways remain conceptual/early-stage and have not yet been experimentally validated beyond the primary autophagy assay system.
Intellectual Property
Early results are beginning to strengthen IP filings. A patent was filed on December 2, 2025 for repurposed compounds ('METHODS FOR ENHANCING AUTOPHAGY USING REPURPOSED PHARMACEUTICAL COMPOUNDS'), and VitaFast LLC (Delaware) has been formed to hold and manage project IP. The IP-NFT structure is registered on the Molecule protocol. Screened compounds show high chemical variability and no similarity to pre-existing autophagy inducers, suggesting strong novel IP potential. FTO analysis indicates a favorable position with differentiation from mTOR inhibitors and existing NPC therapies. However, composition-of-matter patents for the novel NCE lead compounds have not yet been filed (planned for H2 2025/Q4 2025), which is a significant gap given that three lead compounds with 10-100x potency have been identified. The IP strategy is still under development, and the filed patent covers only repurposed compounds (methods of use), not the novel chemical entities which represent the core value.
Utility Of Candidates
Potential drug candidates are clearly emerging. Three lead compounds have been identified with 10-100x higher potency than previous series, and two lead repurposing molecules with prior Phase 1 clinical data show high potency in autophagy assays. However, viability for achieving therapeutic effects remains partially demonstrated: formal EC50/IC50 values have not been reported, no in vivo efficacy data exists yet, and the computational optimization phase to further improve VF-series compounds is still underway. Round 2 NCE structural modifications did not improve target binding over Round 1, indicating SAR challenges that necessitated the pivot to computational optimization. The candidates are at an early stage — promising in cellular assays but unvalidated in animal models. The dual pathway (novel NCEs + repurposed compounds) provides some de-risking. Scored 3 because candidates exist and show promising potency but lack quantitative pharmacological characterization and in vivo validation.
Prospects For Safety
Early safety signals are cautiously positive. Lead compounds show no acute cytotoxicity at therapeutic concentrations in cellular assays, and the mechanism specificity is demonstrated (rescue in Npc1-/- but not Atg5-/- cells, confirming on-target activity rather than non-specific survival effects). The two repurposed lead molecules have prior Phase 1 clinical safety data, which significantly de-risks one development pathway. Worm healthspan and longevity studies are ongoing to assess systemic effects. However, no formal in vivo toxicology data exists for the novel NCEs, no ADMET/DMPK profiling has been completed, and IND-enabling murine safety studies are not planned until 2026. The mechanism of action (autophagy activation) is generally considered manageable but context-dependent (e.g., cancer implications). Scored 3 because early cellular safety data is reassuring and the repurposed compound pathway provides some safety validation, but comprehensive safety assessment is still ahead.
