Abstract

fetched live from OpenAlex

Using a photosensitization-singlet oxygenation-dioxetane cleavage strategy, a photodynamic prodrug system has been developed, whereby drugs bearing carbonyl groups can first be attached to a photosensitizer to give a photosensitizer-drug complex and then released from the complex upon visible light irradiation. Visible light, which has good penetration through tissue, generates singlet oxygen via the photosensitizer, which then releases the prodrug when and where required. With this system, drug mimics and methyl esters of NSAIDs have been successfully incorporated with photosensitizers related to verteporfin and then released by visible light illumination in high to quantitative yields within minutes.

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.
