Synthesis and characterization of an anti-apoptotic immunosuppressive compound for improving the outcome of islet transplantation.
Article in Bioconjugate chemistry, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Mycophenolic acid (MPA) is a commonly used immunosuppressive drug for human islet transplantation. However, it is toxic to transplanted islets, causing primary nonfunction. We recently synthesized a quinic acid derivative, 1,3,4,5-tetrahydroxy-N-propylcyclohexanecarboxamide (KZ41), which has anti-inflammatory and anti-apoptotic effects. We hypothesized that the conjugate (E)-2,3,5-trihydroxy-5-(propylcarbamoyl) cyclohexyl 6-(4-ethoxy-6-methoxy-7-methyl-3-oxo-1,3-dihydroisobenzofuran-5-yl)-4-methylhex-4-enoate (JP-3-110), which is composed of KZ41 and MPA through esterification, can suppress the immune rejection while inducing less toxicity. Early characterization showed that the solubility of JP-3-110 was significantly higher than that of MPA, though JP-3-110 was still poorly water-soluble. The ester bond connecting KZ41 and MPA is stable for a limited duration (<4 weeks). Pharmacological studies demonstrated that JP-3-110 induced significantly less activated caspase 3 and apoptotic cell death of human islets than MPA, while maintaining an equally potent immunosuppressive effect. A similar immunosuppressive effect of JP-3-110 and MPA in humanized NOD.Cg-Prkdc(scid)Il2rg(tm1Wjl)/SzJ (NOD scid gamma, NSG) mice with adoptively transferred human immunity was observed. Taken together, our results demonstrated that JP-3-110 can be a safer immunosuppressive agent for human islet transplantation.
