Claim

On a pre-registered cytochrome-oxidase / COX-inhibitor amnestic retention assay where parent methylene blue restores memory, a selective MAO-B inhibitor (selegiline/rasagiline-class) fails to match that rescue — retention Δ ≤70% of MB (or outside a pre-registered MB-equivalence band).

Why it matters

Completes the isoform panel on the Gonzalez-Lima COX-amnestic assay after N10 (selective MAO-A-i): if metabolic-memory rescue were MAO-B-owned, a selective MAO-B-i should match parent MB; MB’s preferential MAO-A profile predicts MAO-B-i underperforms; if rescue requires parent redox / COX-facing chemistry, selective MAO-B-i should fail. Distinct from N10 (MAO-A arm), N5 (MAO-A-biased generic WM), N8 (Azure B), and N9 (redox-dead) — none ran a selective MAO-B drug on the COX-amnestic panel. Soft-claims: discussion — selective-MAO-B∩MB∩COX-amnestic H2H soft-complete 0; adjacent 40996208 / 22536538 / 41108933 are non-matches; H2H remains UNKNOWN. N5–N10 are not proof of this failure; N10 is the MAO-A complement, not a closed isoform panel.

Mechanism sketch

Redox-vs-MAO assumption-kill on the COX-amnestic / metabolic-memory class: parent MB restores retention after COX inhibition and is a preferential reversible MAO-A inhibitor; selegiline/rasagiline-class selective MAO-B-i improves aged-cognition / related cascades but has no published COX-amnestic retention H2H vs MB. If COX-amnestic rescue is MAO-B-driven, selective MAO-B-i should match MB; preferential MAO-A framing and redox-required rescue both predict selective MAO-B-i underperforms on the same retention panel. Competing caveats: MAO-B occupancy / exposure matching (underperformance could be under-dosing — assay occupancy without a dosing card); soft-complete empty ≠ demonstrated failure; do not collapse with N10’s MAO-A arm as already closed.

Baseline claimed

On a COX-inhibitor amnestic model where parent MB restores retention, a selective MAO-B-i fails to match that rescue (or N5–N10 already closed MAO ownership / isoform panel of metabolic memory).

Baseline measured

MB COX-amnestic / amnestic-network rescue LITERATURE (PMID 12384216; 21087672). MB preferential reversible MAO-A inhibition LITERATURE (PMID 17721552). Rasagiline selective MAO-B tool LITERATURE (PMID 26142126). Selective MAO-B-i vs parent MB on the same COX-amnestic rescue / retention panel UNKNOWN (soft-complete selective-MAO-B∩MB∩COX-amnestic H2H = 0; adjacent 40996208 / 22536538 / 41108933 non-matches). ≤70% MB-equivalence fail PREDICTION. N5–N10 do not already prove this — N10 is MAO-A complement (UNKNOWN there too); N5 generic WM; N8 Azure B; N9 redox-dead; soft-complete empty ≠ failure.

Actionable limitations

Do not treat N5–N10 as proving N11 — N10 left MAO-B open (MAO-A complement only); N5 was A-biased / generic WM; N8/N9 ran metabolite / redox-dead arms, not a selective MAO-B drug; soft-complete empty ≠ demonstrated selective-MAO-B failure on COX-amnestic.
MAO IC50 ≠ brain rescue PD — Ramsay is preferential MAO-A enzyme inhibition; Weinreb 26142126 is aged-cognition / molecular cascades; neither is COX-amnestic retention vs MB.
Occupancy matching — underperformance could be under-dosing relative to MB’s MAO profile; assay MAO-B occupancy / monoamine readout without a dosing card; use the same COX-inhibitor amnestic class where parent MB restores (not a new generic WM or scopolamine substitute); do not collapse N11 with N10 as already closed. No dosing.

Ablate

remove same COX-amnestic / retention contrast of selective MAO-B-i vs parent MB: Without the behavioral H2H on the Gonzalez-Lima class assay, MB rescue LITERATURE and MAO-B tool LITERATURE cannot show selective MAO-B-i fails to match MB rescue.
remove selective MAO-B identity (selegiline/rasagiline-class) with parent-MB preferential-MAO-A framing: Without a verified selective MAO-B tool, underperformance is just “weak monoaminergic drug,” not an assumption-kill of MAO-B-owned COX-amnestic rescue or of isoform-completeness after N10.
remove N5–N10≠proof + soft-complete-empty≠failure + MAO-IC50≠brain-PD + occupancy-matching + N10≠closed-isoform-panel discipline: Treating N5/N8/N9/N10 or empty/adjacent PubMed or Ramsay/Weinreb enzyme-disease priors as already deciding selective-MAO-B COX-amnestic failure would invent a negative result left UNKNOWN.

Refute if

On the pre-registered COX-inhibitor amnestic retention assay, the selective MAO-B-i matches parent MB within the MB-equivalence band (retention Δ >70% of MB or inside band) — especially under exposure/MAO-B-occupancy-matched conditions — so MAO-B-necessity for metabolic-memory rescue survives and redox-required / MAO-A-preferential framing fails.

Ask a human

Lock COX-inhibitor amnestic assay identity (spatial vs discrimination retention class where parent MB restores), selegiline/rasagiline-class selective MAO-B-i tool, exposure/MAO-B-occupancy readout, and optional N10 MAO-A arm before treating any MB metabolic-memory rescue as redox-owned vs MAO-isoform-owned; do not treat N5–N10 as already proving selective-MAO-B COX-amnestic failure; no dosing.
