Abstract

The use of Targeted Covalent Inhibitors (TCIs) is an expanding strategy for the development of innovative drugs. It is driven by two fundamental steps: (1) recognition of the target site by the molecule and (2) establishment of the covalent interaction by its reactive group. The development of new TCIs depends on the development of new warheads. Here, we propose the use of Morita-Baylis-Hillman adducts (MBHAs) to covalently bind Lys strategically placed inside a lipophilic pocket. A human cellular retinoic acid binding protein II mutant (M2) was selected as a test bench for a library of 19 MBHAs. The noncovalent interaction step was investigated by molecular docking studies, while experimentally the entire library was incubated with M2 and crystallized to confirm covalent binding with the target lysine. The results, rationalized through covalent docking analysis, support our hypothesis of MBHAs as reactive scaffolds for the design of lysine-TCIs.

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.
