1 · What the graph read from it

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.

2 · The registry

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

The release of an active drug from the prodrug generates a pro-fragment that typically has no biological activity and could result in adverse effects. By combining two drugs, wherein each drug acts as a pro-fragment of the other drug will eliminate the pro-fragment in the prodrug. As they are prodrugs of each other and are symbiotic, we termed these as symbiotic prodrugs (SymProDs). To test this idea, we generated SymProDs using NFκB inhibitors that contain the reactive α-methylene-γ-butyrolactone moiety and CDK inhibitors with solvent exposed secondary nitrogen atoms. We show that secondary amine prodrugs of α-methylene-γ-butyrolactone containing NFκB inhibitors undergo slow release over a 72 hr period. Using an alkyne-tagged secondary amine prodrug of α-methylene-γ-butyrolactone containing NFκB inhibitor, we demonstrate target engagement. The NFκB-CDK SymProDs were ~20- to 200-fold less active against the corresponding CDK inhibitors in in vitro CDK kinase assays. Growth inhibition studies in a panel of ovarian cancer cell lines revealed potency trends of the SymProDs mirrored those of the single treatments suggesting their dissociation in cells. In conclusion, our results suggest that SymProDs offer a productive path forward for advancing compounds with reactive functionality and can be used as dual targeting agents.
