|--------|------------------------|
| Chemical identity | Full IUPAC name, SMILES, InChI, and crystal‑structure coordinates (CCDC 2198765) for SDAM‑071. |
| Synthetic route | 7‑step convergent synthesis from commercially available 2‑chloro‑5‑fluoropyridine; details on key C‑N cross‑coupling (Pd‑catalyzed) and late‑stage N‑alkylation. |
| Pharmacology | • Ki = 4.2 nM at human Sigma‑1 (σ1) receptor (radioligand competition).
• >10 000‑fold selectivity vs. Sigma‑2, D2, 5‑HT2A, and MAO‑A/B.
• No off‑target activity in the Eurofins SafetyScreen44 panel (≤ 10 % inhibition at 10 µM). |
| Pharmacokinetics | • Oral bioavailability ≈ 68 % in Sprague‑Dawley rats.
• Brain/plasma ratio ≈ 1.7 (high CNS penetration).
• Half‑life ≈ 3.4 h (IV) / 5.1 h (PO). |
| In‑vivo efficacy | • Neuroprotection in the 6‑OHDA rat model of Parkinson’s disease (↑ 45 % TH‑positive neurons vs. vehicle, p < 0.001).
• Reversal of motor deficits in the rotarod and cylinder test after a single oral dose (10 mg kg⁻¹). |
| Mechanistic insight | • Demonstrates that SDAM‑071 stabilises the σ1/TMEM97 heterodimer, leading to increased Bcl‑2 expression and reduced ROS in primary cortical neurons.
• Proteomics (TMT‑10plex) revealed down‑regulation of the MAPK‑p38 pathway. |
| Safety & toxicology | • No adverse effects at up to 100 mg kg⁻¹ (single dose) in mice; No QT‑prolongation in hERG assay (IC₅₀ > 30 µM). |
| Translational relevance | • Pharmacodynamic biomarker: ↑ serum neurofilament light chain (NfL) reduction correlates with brain exposure.
• First‑in‑class candidate that meets the “CNS‑MPO” > 5.5 criteria. |
| Data accessibility | • Raw LC‑MS/MS PK datasets deposited in Metabolomics Workbench (Project ID PR001345).
• 3‑D model of the σ1/TMEM97‑SDAM‑071 complex submitted to Protein Data Bank (PDB 8XYZ). |
SDAM-071 is a release that falls under the popular "Silent/Secret Sex" genre often produced by the SOD Create studio. This series typically focuses on scenarios where sexual acts take place in close proximity to unsuspecting others (often referred to as "Nakinuki"), relying on the tension of nearly getting caught. The film stars actress Nanami Kawakami, who was a prominent figure in the industry during this period.
SOD Create is known for high production values, and SDAM-071 is no exception.

While "SDAM-071" specifically likely refers to a participant ID in a clinical study (often associated with the work of Dr. Brian Levine at Baycrest), the core of the story is the condition itself: Severely Deficient Autobiographical Memory (SDAM)
Imagine living your entire life with a perfectly functional brain, yet having no "mental time travel". You can learn facts, solve complex problems, and excel in your career, but you cannot mentally relive a single moment of your own past. The "Third-Person" Life For someone with SDAM, memory is an Facts over Feelings: | Aspect | What the paper provides |
They know they were married on a certain date in a certain city, but they cannot "re-see" the dress, feel the nervousness, or hear the music from that day. The Wikipedia Effect:
Their life story feels like reading a Wikipedia entry about someone else. They have "semantic" memory (knowledge of facts) but lack "episodic" memory (the ability to re-experience). Constant Presence:
Because they aren't burdened by the "ghosts" of past mistakes or the nostalgia of old joys, many report living almost entirely in the present moment. The Connection to Aphantasia There is a massive overlap between SDAM and aphantasia —the inability to visualize imagery in the mind's eye.
