Aripiprazole, a partial dopamine D2/D3 and serotonin 5-HT1A agonist used in schizophrenia and bipolar disorder, inhibits cathepsin S (CTSS) and dampens microglial MHC-II antigen presentation to reduce intrathecal T-cell reactivation, representing a mechanistically novel repurposing candidate for smoldering multiple sclerosis where CNS-resident CTSS overexpression sustains chronic perilesional inflammation (MM-GBSA ΔG −35.1 ± 3.4 kcal/mol, 2 ns MD, RMSD 1.95 ± 0.52 Å, CTSS-selective over cathepsin B)

Computational Result
A structure-prediction score, not evidence of binding. No wet-lab assay has been run.
Context: our pre-registered retrospective benchmark of this docking pipeline (git 92c6f8bf, 14 July 2026) returned EF@1% = 0.00 across 14 targets — it recovered no known actives in the top 1%. Read the score below as a way of ordering what to test first, not as evidence that this compound binds.
Aripiprazole binds CTSS: MM-GBSA dG=-35.11 kcal/mol, 2 ns MD stable RMSD=1.95 A, CTSS-selective over CTSB. CNS repurposing panel for smoldering MS (AU2026905146).
Method: MM-GBSA (GB-OBC2, 2 ns explicit-solvent MD, AMBER ff14SB + openff-2.0.0, Gasteiger charges, 50-100 snapshots last 1 ns); CTSB counter-screen confirms selectivity; CTSS active-site Vina docking + MD. · Result: supported · Confidence: 0%
Formal Verification
Z3 checks whether the hypothesis is internally consistent, not whether it is empirically true.
