Abstract

fetched live from OpenAlex

Several sulfur-containing compounds, isolated from garlic, have been implicated as highly active antithrombotic agents. We have prepared 10 new aromatic disulfides and an aromatic thiosulfonate in order to determine the in vitro response of human platelets to dosages of these compounds. The poor biological activity of PhSSCH3 was enhanced by the introduction of, inter alia, a nitro group onto the aromatic ring. The nitro group increased potency by activating the disulfide linkage. Anti-platelet aggregation activity was also enhanced by increasing the lipophilicity of one test compound. The ability of an aromatic disulfide to inhibit platelet aggregation can be enhanced by appending an electron-withdrawing group to the aromatic ring. The results presented establish that the aromatic thiosulfonate is a very effective inhibitor of platelet aggregation.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
