Pharmacophore derived 3D-QSAR, molecular docking, and simulation studies of quinoxaline derivatives as ALR2 inhibitors

Article

Author: Singh, Yogesh ; Kumar, Niraj ; Thareja, Suresh ; Singh, Satwinder ; Kulkarni, Swanand

Aldose Reductase 2 (ALR2), a key enzyme of the polyol pathway, plays a crucial role in the pathogenesis of diabetic complications. Quinoxaline scaffold-based compounds have been identified as potential ALR2 inhibitors for the management of diabetic complications. In the present work, molecular dynamic simulation studies in conjugation with pharmacophore mapping and atom-based 3D-QSAR were performed on a dataset of 99 molecules in comparison with Epalrestat (reference) to mark the desirable structural features of quinoxaline analogs to generate a probable template for designing novel and effective ALR2 inhibitors. The most potent compound 81 was subjected to MD simulation studies and found to be stable, with better interactions with the binding pocket as compared to Epalrestat. The MM-GBSA and MM-PBSA calculations showed that compound 81 possessed binding free energies of -35.96 and -4.92 kcal/mol, respectively. Atom-based 3D-QSAR yielded various pharmacophoric features with excellent statistical measures, such as correlation coefficient (R² value), F-value (Fischer ratio), Q² value (cross-validated correlation coefficient), and Pearson's R-value for training and test sets. Furthermore, the pharmacophore mapping provided a five-point hypothesis (AADRR) and docking analysis revealed the active ligand-binding orientations on the active site's amino acid residues TYR 48, HIE 110, TRP 111, and TRP 219. The results of this study will help in designing potent inhibitors of ALR2 for the management of diabetic complications.Communicated by Ramaswamy H. Sarma.

Oleogels for the ocular delivery of epalrestat: formulation, in vitro, in ovo, ex vivo and in vivo evaluation

Article

Author: Kattar, Axel ; Vivero-Lopez, Maria ; Chauhan, Anuj ; Mudakavi, Rajeev ; Concheiro, Angel ; Alvarez-Lorenzo, Carmen

Abstract:

The ocular administration of lipophilic and labile drugs such as epalrestat, an aldose reductase inhibitor with potential for diabetic retinopathy treatment, demands the development of topical delivery systems capable of providing sufficient ocular bioavailability. The aim of this work was to develop non-aqueous oleogels based on soybean oil and gelators from natural and sustainable sources (ethyl cellulose, beeswax and cocoa butter) and to assess their reproducibility, safety and efficiency in epalrestat release and permeation both ex vivo and in vivo. Binary combinations of gelators at 10% w/w resulted in solid oleogels (oleorods), while single gelator oleogels at 5% w/w remained liquid at room temperature, with most of the oleogels displaying shear thinning behavior. The oleorods released up to 4 µg epalrestat per mg of oleorod in a sustained or burst pattern depending on the gelator (approx. 10% dose in 24 h). The HET-CAM assay indicated that oleogel formulations did not induce ocular irritation and were safe for topical ocular administration. Corneal and scleral ex vivo assays evidenced the permeation of epalrestat from the oleorods up to 4 and 2.5 µg/cm2 after six hours, respectively. Finally, the capacity of the developed oleogels to sustain release and provide significant amounts of epalrestat to the ocular tissues was demonstrated in vivo against aqueous-based niosomes and micelles formulations loaded with the same drug concentration. Overall, the gathered information provides valuable insights into the development of oleogels for ocular drug delivery, emphasizing their safety and controlled release capabilities, which have implications for the treatment of diabetic neuropathy and other ocular conditions.Graphical abstract

Aldose reductase with quinolone antibiotics interaction: In vitro and in silico approach of its relationship with diabetic complications

Article

Author: Türkeş, Cüneyt

Aldose reductase (AR, EC1.1.1.21), a member of the aldo-keto reductase family, is critically implicated in the pathogenesis of chronic complications associated with diabetes mellitus, including neuropathy, nephropathy, and retinopathy. Hyperglycemia-induced AR overactivity results in intracellular sorbitol accumulation, NADPH depletion, and oxidative stress. Consequently, AR is recognized as a key mediator of oxidative and inflammatory signaling pathways involved in diverse human pathologies such as cardiovascular diseases, inflammatory disorders, and cancer. This has sparked renewed interest in developing novel AR inhibitors (ARIs) with enhanced therapeutic profiles. In this study, we evaluated the inhibitory potential of five quinolone antibiotics-gatifloxacin, lomefloxacin, nalidixic acid, norfloxacin, and sparfloxacin-as ARIs relevant to various physiological and pathological conditions. Through comprehensive in vitro and in silico analyses, we explored these antibiotics' binding interactions and affinities within the AR active site. Our findings reveal that these quinolones moderately inhibit AR at micromolar concentrations, with inhibition constants (K_Is) ranging from 1.03 ± 0.13 μM to 4.12 ± 0.51 μM, compared to the reference drug epalrestat (K_I of 0.85 ± 0.06 μM). The combined in vitro and in silico results underscore significant interactions between these drugs and AR, suggesting their potential as therapeutic agents against the aforementioned pathological conditions. Furthermore, these insights will aid in optimizing clinical dosing regimens and mitigating unexpected drug-drug interactions when these antibiotics are co-administered with other treatments.

Phase III clinical trial of pediatric subjects with PMM2-CDG begins crossover to open label epalrestat

STURGIS, Mich., March 18, 2024 /PRNewswire/ -- Maggie's Pearl, a collaboration between Perlara, Maggie's Cure, and the Mayo Clinic, announced that the Phase III trial of oral epalrestat therapy in pediatric subjects with PMM2-CDG (formerly, Congenital Disorder of Glycosylation Type 1a) has been green-lighted to transition to open label. All study subjects on placebo may transition to open label epalrestat at their 15-month study visit. The principal investigator, study team, participants, and their families remain blinded to original treatment assignments until all subjects reach their 15-month visit. The crossover recommendation was unanimous among an independent three-member data monitoring committee, comprising two physician scientists with PMM2 expertise and a biostatistician. The DMC concluded the planned interim analysis and determined that the trial can proceed safely. They recommended that each study participant continue with their randomly assigned treatment until the 15-month visit, when they can transition to open label epalrestat. Administered by the Mayo Clinic, the clinical trial is a prospective, single-center, randomized, double-blind, placebo-controlled study. In December 2021, the Food and Drug Administration notified Maggie's Pearl that the Phase III clinical trial in 40 patients with PMM2-CDG could proceed. The trial recruited 38 study subjects and closed enrollment in November 2023. The first 29 participants will complete their 15-month visits over the next 2-3 months. PMM2-CDG (phosphomannomutase-2-congenital disorder of glycosylation) is caused by mutations in a gene that supplies the instructions for making the PMM2 enzyme. The enzyme is involved in a process called glycosylation, in which sugar chains are created, altered, and chemically attached to specific proteins to form glycoproteins. Those proteins are key to normal growth and function of tissues and organs. No approved treatment options exist for patients with PMM2-CDG. "The DMC recommendation to allow study participants to receive epalrestat upon completing 15 months of randomized treatment is very encouraging," said Ethan Perlstein, CEO of Maggie's Pearl. "We can't thank participating families enough. They are medical pioneers and an example for all rare disease communities of what is possible despite the hardships of a placebo-controlled study. We look forward to opening discussions with FDA in the coming months to make epalrestat widely available for all PMM2-CDG families." The primary study objective is to evaluate the safety and probable benefit of oral epalrestat therapy in pediatric subjects with PMM2-CDG. More at: clinicaltrials.gov/ct2/show/NCT04925960. About Maggie's Pearl : Established in August 2020, Maggie's Pearl LLC is a joint venture between Perlara, Maggie's Cure, and the Mayo Clinic to identify potential drug therapies to treat and improve the lives of PMM2-CDG patients. Maggie's Pearl was inspired by Maggie Carmichael, a 10-year-old girl from Sturgis, Michigan, who was diagnosed with PMM2-CDG at eight months of age. At that time, Maggie's parents were told there was no treatment for the rare, and potentially fatal, genetic disease. Globally, roughly 1,000 people are known to have PMM2-CDG. More at .

Maggie's Pearl Initiates Phase III Clinical Trial for Treatment of Patients with PMM2-CDG

Phase III epalrestat clinical trial to evaluate safety, tolerability, and clinical and metabolic improvement of pediatric subjects with PMM2-CDG STURGIS, Mich., Jan. 9, 2023 /PRNewswire/ -- Maggie's Pearl, a joint venture between Perlara, Maggie's Cure, and the Mayo Clinic, has started a Phase III clinical treatment trial to evaluate safety, tolerability, and clinical and metabolic improvement of pediatric subjects with PMM2-CDG (formerly known as Congenital Disorder of Glycosylation Type 1a) on oral epalrestat therapy versus a placebo. Administered by the Mayo Clinic, the clinical trial is a prospective, single-center, randomized, double-blind, placebo-controlled study. Maggie's Pearl received Food and Drug Administration approval in December 2021 to begin the Phase III clinical trial in 40 patients with PMM2-CDG. Now, the study is actively recruiting, and the first two study subjects were dosed in December 2022. PMM2-CDG, or phosphomannomutase-2-congenital disorder of glycosylation — is caused by mutations in a gene that supplies the instructions for making the PMM2 enzyme, which is involved in a process known as glycosylation. In that process, sugar chains are created, altered, and chemically attached to specific proteins to form glycoproteins. Those proteins are key to normal growth and function of tissues and organs. "This trial is the culmination of five years of research attempting to identify a new treatment option for pediatric PMM2-CDG," said Ethan Perlstein, CEO of Maggie's Pearl. "The start of this trial is an inflection point in our research. If this study demonstrates epalrestat to be safe and effective, families could finally have a viable treatment option for children living with PMM2-CDG." The primary study objective is to evaluate the safety and probable benefit of oral epalrestat therapy in pediatric subjects with PMM2-CDG. Study outcomes include evaluating the metabolic improvement of pediatric subjects treated with oral epalrestat therapy compared to those receiving the placebo. Additional areas of evaluation are safety, clinical improvement, and pharmacokinetics (PK) of oral epalrestat therapy, as well as urine polyols, adverse events, laboratory data, and other measures.
