Quality by design based ecofriendly HPLC analytical method for simultaneous quantification of erastin and lenalidomide in mesoporous silica nanoparticles.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The aims of this work to optimize and validate a RP-HPLC method to quantify erastin (ERT) and lenalidomide (LND) in mesoporous silica nanoparticles (MSNs). The Design of Experiments (DoE) strategy optimized the RP-HPLC method. The independent variables were buffer ratio, buffer pH, flow rate and injection volume. The dependent variables were retention time (Rt), Peak area, and resolution between the peaks of the analytes. The optimized conditions were: buffer ratio 68% and methanol 32%, flow rate 0.8 mL/min, buffer pH 5.8, and injection volume 10 µL. The ICH Q2(R1) recommendations were followed in the validation of the optimized RP-HPLC method. The method demonstrated linearity of more than 0.99 for both ERT and LND. The LOD and LOQ were 0.75 and 1.62 ng/mL for ERT; for LND 31.25 and 50 ng/mL. The specificity of the established RP-HPLC method was unaffected by the MSNs matrix. The drugs-loaded MSNs were analyzed using the suggested RP-HPLC technique. The % entrapment efficiency of ERT and LND was found to be 72.65 and 79.50%, and drug loading of ERT and LND was found to be 14 and 17% in MSNs, respectively. The optimized RP-HPLC method was used to check the in-vitro drug release of the ERT and LND from the ERT-LND@MSNs. Surface properties of synthesized MSNs was checked through particle and SEM analysis. The developed analytical method was eco-friendly according to AGREE analysis and GAPI analysis.
