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

background(-)-Cannabidiol (CBD) is a naturally occurring terpenoid belonging to the cannabinoid family, which is isolated from the Cannabis sativa L. plant. It possesses significant therapeutic potential, providing minimal side effects and no psychoactive activity. However, CBD applications are limited by a poor aqueous solubility and low bioavailability.

objectiveTo address these limitations and investigate the impact of structural modification on solubility, we plan in this work the synthesis of a series of CBD conjugates along with the evaluation of their antitumor activity.

methodsConjugates are characterized by Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS) techniques, along with the solubility in water, glycerine, n-hexane and isooctane evaluated by High-Performance Liquid Chromatography (HPLC). The antitumoral activity of the CBD conjugates has been tested using cytotoxicity (IC

resultsSpecifically, oligo(ethylene glycol)-, alkyl- and L-valine-functionalized CBD derivatives are synthesized via selective esterification of its phenolic groups in good yields. Solubility profiles revealed a marked improvement compared to CBD. Notably, oligo(ethylene glycol) derivatives significantly enhanced solubility in water and glycerine, with 1b exhibiting a 14-fold increase in water solubility. The L-valine bis-conjugated derivative 4 also exhibited substantially improved solubility across all tested solvents, reaching up to a 13-fold increase in glycerine. In contrast, alkyl conjugates 2a,b showed only modest improvements. In addition, the in vitro evaluation against A549 revealed improved cytotoxic activity for 1a, 1b and 4 compared to native CBD, and with 1a additionally displaying antimigratory and colony formation inhibitory effects.

conclusionsCollectively, our results highlight the critical role of conjugate structure in modulating physicochemical and biological properties of CBD and underscore the potential of these CBD conjugates as promising candidates for further pharmacological investigation and development.
