One-Pot Bioisosteric Replacement of Alkyl Carboxylic Acids via Organic Photoredox Catalysis.
Article in Organic letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Drug development is often hindered by the pharmacokinetic and physicochemical limitations of lead compounds. Bioisosteric replacement is commonly employed to bolster drug viability; however, methods for accessing drug analogs are often synthetically inefficient. To address this challenge, we disclose strategies to access carboxylic acid bioisosteres via organic photoredox catalysis. A one-pot method enables the direct conversion of carboxylic acids to their most common bioisostere, tetrazoles. Additional functionalization to an amidoxime intermediate affords access to three other bioisosteres: oxathiadiazolones, oxadiazolones, and oxadiazole thiones. HPLC lipophilicity measurements of carboxylic acids and bioisostere derivatives illustrate the synthetic value of these methods for improving lead compound viability.
