Soft-complete 0; dual selective MAOI vs parent MB on COX-amnestic assay UNKNOWN. N5–N11 are not proof — do not collapse N10+N11 into dual proof.
On a pre-registered cytochrome-oxidase / COX-inhibitor amnestic retention assay where parent methylene blue restores memory, a combined selective MAO-A inhibitor (clorgyline-class) + 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).
Closes dual-isoform escape on the Gonzalez-Lima COX-amnestic assay after N10 (selective MAO-A alone) and N11 (selective MAO-B alone): even if each single arm fails, A+B could still match MB; N12 tests that combo vs parent MB. If COX-amnestic rescue were dual-MAO-driven, A+B should match MB; preferential redox / COX-facing framing and MB’s preferential MAO-A enzyme profile both predict the dual selective combo underperforms. Distinct from N10/N11 (single-isoform), N5 (MAO-A generic WM), N8 (Azure B), N9 (redox-dead) — none ran dual selective MAOI vs parent MB on this assay. Soft-claims: discussion — soft-complete 0; H2H UNKNOWN; N5–N11 are not proof — do not collapse N10+N11 into dual proof.
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; selective MAO-A and MAO-B tools exist (clorgyline-class; rasagiline/selegiline-class) but no published dual-combo COX-amnestic retention H2H vs MB. Dual-isoform escape: N10/N11 leave open that A+B together could still match MB; N12 closes that escape on the same assay. Competing caveats: occupancy / exposure matching (underperformance could be under-dosing — assay MAO-A/B occupancy without a dosing card); soft-complete empty ≠ demonstrated failure; MAO IC50 ≠ brain rescue PD.
On a COX-inhibitor amnestic model where parent MB restores retention, combined selective MAO-A-i + MAO-B-i fails to match that rescue (or N5–N11 already closed MAO ownership / dual-isoform escape of metabolic memory).

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).

On a pre-registered cytochrome-oxidase / COX-inhibitor amnestic retention assay where parent methylene blue restores memory, a redox-disabled MB analogue (primary N-acetyl / Wen 2011 class; optional confirmatory 10-N SAR) fails to match that rescue — retention Δ ≤70% of MB (or outside a pre-registered MB-equivalence band).
Closes the Wen→Gonzalez-Lima bridge: if metabolic-memory rescue requires parent redox / alternative electron transfer, a redox-disabled analogue should fail on the same COX-amnestic panel where MB restores retention. Distinct from N7 (redox-dead ≠ MB on generic WM) and from N8 (Azure B on COX-amnestic) — neither ran redox-dead × COX-amnestic. Soft-claims: discussion — N-acetyl/redox-dead MB ∩ (memory|amnestic|retention) soft-complete 0; H2H remains UNKNOWN. N5–N8 are not proof of this failure.
Redox-vs-MAO assumption-kill on the COX-amnestic / metabolic-memory class: parent MB accepts electrons from NADH → cytochrome c and restores retention after COX inhibition; N-acetyl / redox-disabled MB loses mitochondrial electron transfer / neuroprotection (Wen); 10-N SAR drops protective potency and mito ET. If rescue tracks parent redox / COX-facing structure, the redox-dead analogue underperforms on the same retention panel; if rescue is MAO-driven or structure-promiscuous, it may still match. Competing caveats: MAO occupancy of the chosen analogue (a redox-dead that retains MAO dissociates redox from MAO; one that also loses MAO confounds the kill); PK / brain exposure; soft-complete empty ≠ demonstrated failure.
On a COX-inhibitor amnestic model where parent MB restores retention, a redox-disabled MB analogue fails to match that rescue (or Wen already kills metabolic-memory rescue / N5–N8 already closed redox ownership of cognition).

On a pre-registered cytochrome-oxidase / COX-inhibitor amnestic retention assay where parent methylene blue restores memory, Azure B fails to match that rescue — retention Δ ≤70% of MB (or outside a pre-registered MB-equivalence band) — despite Azure B’s stronger MAO-A potency under matched enzyme conditions.
Popular MAOI frame: if MB metabolic-memory rescue is “mild MAOI,” the more potent demethyl metabolite Azure B should match or beat MB on the same COX-amnestic rescue. N5–N7 left Azure B×memory soft-complete and never ran the Gonzalez-Lima COX-amnestic head-to-head; they are not proof of this failure. Soft-claims: discussion — Azure B∩(memory|COX-amnestic rescue) soft-complete empty / false positives only; rescue mismatch remains UNKNOWN.
Redox-vs-MAO assumption-kill on the COX-amnestic / metabolic-memory class: if rescue tracks MAO-A potency, Azure B (~6× stronger MAO-A than MB) should match or exceed parent MB; if rescue tracks parent redox / COX-facing structure, Azure B underperforms on the same retention panel. Callaway 2002 / Gonzalez-Lima class: low-dose MB restores spatial retention after COX inhibition. Rojas 2011: MB shows beneficial network effects in an amnestic model. Petzer 2012: Azure B high-potency reversible MAO-A (~6× MB). Ramsay 2007: MB potent reversible MAO-A. Competing caveats: PK / brain exposure; assay must stay COX-inhibitor amnestic retention (not a new generic WM substitute); soft-complete empty ≠ demonstrated failure.
On a COX-inhibitor amnestic model where parent MB restores memory retention, Azure B fails to match that rescue despite stronger MAO-A (or N5–N7 already settled Azure B ≠ MB on cognition).
MB COX-amnestic / amnestic-network rescue LITERATURE (PMID 12384216; 21087672). Azure B stronger MAO-A than MB LITERATURE (PMID 22197611). MB MAO-A potency LITERATURE (PMID 17721552).

On a pre-registered rodent working-memory task, a redox-disabled methylene blue analogue (primary: N-acetyl-MB per Wen 2011; optional confirmatory 10-N SAR analogue per Wen 2012) fails to match parent MB — WM Δ ≤70% of MB (or outside a pre-registered MB-equivalence band).
Popular frame: if MB working memory tracks mitochondrial redox cycling, killing the redox center should abolish the WM signal even when related phenothiazine chemistry remains. N5/N6 left redox-dead×WM and Azure B×WM soft-complete UNKNOWN; Wen endpoints ≠ WM. They are not proof of this failure. Soft-claims: discussion — N-acetyl-MB∩memory soft-complete 0; behavioral mismatch remains UNKNOWN.
Redox-vs-MAO assumption-kill: if WM tracks mitochondrial redox, redox-disabled N-acetyl / 10-N analogues underperform parent MB on the same WM task; if WM tracks MAO-A or non-redox phenothiazine features, a redox-dead analogue that retains MAO may still match. Wen 2011: N-acetyl / redox-disabled MB loses mitochondrial electron-transfer / OCR / neuroprotection (not WM). Wen 2012: 10-N / side-chain SAR drops protective potency and mitochondrial ET enhancement (still neuroprotection/ROS, not WM). Gonzalez-Lima: low-dose MB improves discrimination / metabolic memory without a redox-dead arm. Ramsay: MB is a potent reversible MAO-A inhibitor. Competing caveats: analogue identity (pick one primary kill tool); MAO occupancy of the chosen analogue UNKNOWN; soft-complete empty ≠ demonstrated failure.
MB working-memory benefit is explained by mitochondrial redox cycling, so a redox-disabled analogue should fail to match parent MB on the same WM task (or N5/N6 already settled redox ownership of WM).

On a pre-registered rodent working-memory task, Azure B alone fails to match parent methylene blue — WM Δ ≤70% of MB (or outside a pre-registered MB-equivalence band) — despite Azure B’s stronger MAO-A potency under identical enzyme conditions.
Popular MAOI framing: if MB WM is “mild MAOI,” the more potent demethyl metabolite Azure B should match or beat MB on the same task. N5 flagged the metabolite confound and asked selective MAO-A-i ≠ MB; it did not run Azure B vs MB on WM and is not proof of this failure. Soft-claims: discussion — Azure B∩memory soft-complete 0; behavioral mismatch remains UNKNOWN.
Redox-vs-MAO assumption-kill: if WM tracks MAO-A potency, Azure B (≥6× stronger MAO-A than MB in vitro) should match or exceed MB; if WM tracks parent redox/structure, Azure B underperforms on the same WM task. Azure B is MB’s demethyl metabolite and a high-potency reversible MAO-A inhibitor (IC50 ≈11 nM vs MB ≈70 nM under identical conditions); MB is a potent reversible MAO-A inhibitor; low-dose MB improves discrimination / metabolic memory; redox-disabled N-acetyl MB loses mitochondrial ET / neuroprotection (not a declared WM endpoint). Competing caveats: PK / brain exposure may make Azure B underperform without killing the MAO story; soft-complete empty ≠ demonstrated failure.
MB working-memory benefit is explained by mild MAO-A inhibition, so the more potent demethyl metabolite Azure B should match or beat MB on the same WM task (or N5’s metabolite confound already settles Azure B WM).

On a pre-registered rodent working-memory task under MAO-comparable conditions, a selective MAO-A inhibitor fails to match parent methylene blue — WM Δ ≤70% of MB (or outside a pre-registered MB-equivalence band).
Popular nootropic framing collapses MB cognition into a mild MAOI story. N3 mapped MAO-A and mitochondrial redox as separate LITERATURE legs and left WM co-panel UNKNOWN; it did not already prove selective MAO-A-i ≠ MB on one task. Soft-claims: discussion — behavioral mismatch is still untested.
If WM tracks MAO-A, selective MAO-A-i (clorgyline/moclobemide-class) at matched occupancy should reproduce MB; if WM tracks mitochondrial redox, selective MAO-A-i underperforms while a redox-disabled MB analogue loses the WM signal. MB is a potent reversible MAO-A inhibitor (~70 nM) and Azure B is stronger (~11 nM); Wen redox-dead kill is mito ET/neuroprotection, not WM; Gonzalez-Lima maps low-dose MB to COX/metabolic memory without a MAO arm. Metabolite confound: in vivo “MB” WM could still be Azure B–MAO even if parent redox matters in vitro — Azure B ∩ memory = 0 in scout search.

Under sleep restriction, oral-creatine cognitive / working-memory benefit is not adequately indexed by plasma (or serum) creatine — a pre-registered subject-level contrast must show WM (or processing-speed) Δ covaries more strongly with ³¹P-MRS PCr or PCr/Pi than with plasma creatine (|r_WM,PCr| − |r_WM,plasmaCr| ≥ 0.20), or plasma-alone mediation fails while PCr mediation holds.

Methylene blue working-memory benefit is not explained by MAO-A inhibition — on a pre-registered rodent WM task, a redox-disabled MB analogue that retains MAO-A potency fails to match parent MB (WM Δ ≤50% of parent or outside a pre-registered parent-equivalence band), and a selective MAO-A inhibitor at matched MAO occupancy does not reproduce parent MB WM within that same band.
Nootropic framing treats MB cognition as a mild MAOI story because MB and Azure B potently inhibit MAO-A. Mitochondrial redox-cycling literature shows a redox-disabled analogue kills electron-transfer / neuroprotection — but that paper is not a WM assay. Soft-claims: ship as discussion — kill the MAO-explains-WM slogan without inventing a Wen WM result.
MB accepts electrons from NADH and feeds cytochrome c; N-acetyl / 10-N-impaired analogues lose mitochondrial complex activity and protective potency. Separately, MB is a tight-binding reversible MAO-A inhibitor (~70 nM) and Azure B is stronger (~11 nM), which explains serotonin-toxicity risk with SSRIs. Low-dose MB memory work maps to cytochrome oxidase / metabolic enhancement, not MAO panels — so MAO potency and WM PD are different endpoint families until a dissociation assay exists.
MB improves working memory because it inhibits MAO-A (same axis as serotonin toxicity / Azure B potency).
Redox-disabled N-acetyl-MB loses mitochondrial ET / complex activity LITERATURE (PMID 21454572). 10-N SAR ~1000× drop protective potency LITERATURE (PMID 23118969). MB ↑ COX and discrimination / metabolic-memory rescue LITERATURE (PMID 17428524; 21087672). MB MAO-A ~70 nM; Azure B ~11 nM LITERATURE (PMID 17721552; 22197611). Seed overstates Wen as WM — Wen endpoints are mitochondrial/neuroprotection, not working memory LITERATURE limitation. Paired WM ∩ MAO ∩ redox dissociation panel UNKNOWN. ≤50% parent-equivalence fail PREDICTION.
