Abstract
Cdk5 regulatory associated protein 1-like 1 (CDKAL1) is one of the most reliable risk genes for type 2 diabetes mellitus (T2DM). Because CDKAL1 controls glucose-induced insulin secretion by KATP channel responsiveness and faithful decoding of Lys codons to prevent mistranslation in pancreatic β-cells, a rescuer of CDKAL1 defects is expected as a new antidiabetes drug. We found that eperisone analogs effectively rescued mistranslation in a MiaB-deficient Escherichia coli dual-luciferase reporter gene system (MiaB is a prokaryotic homologue of eukaryotic CDKAL1). Among them, compounds 1f and 1t demonstrated significant antihyperglycemic efficacy in an oral glucose tolerance test by subcutaneous administration in Wister rats, along with a significant enhancement of insulin secretion in the MIN6 insulinoma cell line without cytotoxicity. These results indicate that CDKAL1 could be a viable molecular target for a new anti-T2DM medication.
期刊介绍:
ACS Medicinal Chemistry Letters is interested in receiving manuscripts that discuss various aspects of medicinal chemistry. The journal will publish studies that pertain to a broad range of subject matter, including compound design and optimization, biological evaluation, drug delivery, imaging agents, and pharmacology of both small and large bioactive molecules. Specific areas include but are not limited to:
Identification, synthesis, and optimization of lead biologically active molecules and drugs (small molecules and biologics)
Biological characterization of new molecular entities in the context of drug discovery
Computational, cheminformatics, and structural studies for the identification or SAR analysis of bioactive molecules, ligands and their targets, etc.
Novel and improved methodologies, including radiation biochemistry, with broad application to medicinal chemistry
Discovery technologies for biologically active molecules from both synthetic and natural (plant and other) sources
Pharmacokinetic/pharmacodynamic studies that address mechanisms underlying drug disposition and response
Pharmacogenetic and pharmacogenomic studies used to enhance drug design and the translation of medicinal chemistry into the clinic
Mechanistic drug metabolism and regulation of metabolic enzyme gene expression
Chemistry patents relevant to the medicinal chemistry field.
