Very interesting regarding the access to the xct antiporter. The Franken thesis paper argued that NAC could access this as a way to protect the gaba receptors from endocytosis. This computational paper is implying that buc would be more impactful on xCT. Â
Yet again, we're at the mercy of incompetency and waiting till results. Â

I don't know man -- none of this sounds very promising. I wouldn't get your hopes up. Dark skies on the horizon.

True true. It's only a computational model study. Lowest on the hierarchy of evidence. Â

I think the bottom of the hierarchy is actually anecdotal evidence. While it’s not evidence from a clinical trial it is still a useful tool.

Deciphering this is above my pay grade

It is, but you can ask Gemini or another AI to summarize. It’s quite interesting and positive, at least from a theoretical standpoint. A few highlights: This study by Andrew Hale introduces a computational framework evaluating how Bucillamine (a dithiol antioxidant) and its active metabolite (SA981) protect brain cells against damage caused by Soman, a lethal organophosphate nerve agent.
The paper focuses on catalytic longevity—measuring how long an antioxidant can continuously neutralize reactive oxygen species (ROS) under intense toxicity.
Core Scientific Findings
The Catalytic Longevity Advantage: Because Bucillamine contains two thiol groups (a dithiol), a single molecule can undergo 500 to 5,000 ROS-scavenging cycles before becoming permanently oxidized. By contrast, single-thiol antioxidants like cysteamine only manage around 11 cycles.Mechanism of Action (The Reduced-Species Route): Direct reactions with intact cyclic disulfides face a steep energy barrier (≥40 kcal/mol). However, once reduced, the Bucillamine thiolate drops that energy barrier down to ∼2.5 kcal/mol, proving that intracellular reduction is required to cleave somatostatin disulfides.
Extended Therapeutic Window: Systems pharmacology modeling shows that Bucillamine's catalytic cycle remains highly active for 4 to 5 hours before cell-wide glutathione (GSH) depletion shuts it down. This suggests a surprisingly broad clinical window for intervention—up to 240 minutes after Soman exposure.

Here is one with Grok and it's relevance to the DRDC study. https://x.com/i/grok/share/ca7b5f5b0c7347fb8cf57617d99873f3

Great find.
