Once considered potential liabilities, the modern era witnesses a renaissance of interest in covalent inhibitors in drug discovery. The available toolbox of electrophilic warheads is limited by constraints on tuning reactivity and selectivity. Following our work on a class of ferroptotic agents termed CETZOLEs, we discovered new tunable heterocyclic electrophiles which are capable of inducing ferroptosis. The biol. evaluation demonstrated that thiazoles with an alkyne electrophile at the 2-position selectively induce ferroptosis with high potency. D. functional theory calculations and NMR kinetic studies demonstrated the ability of our heterocycles to undergo thiol addition, an apparent prerequisite for cytotoxicity. Chemoproteomic anal. indicated several potential targets, the most prominent among them being GPX4 protein. These results were further validated by western blot anal. and the cellular thermal shift assay. Incorporation of these heterocycles into appropriate pharmacophores generated highly cytotoxic agents such as the analog BCP-T.A (I), with low nM IC50 values in ferroptosis-sensitive cell lines. In the experiment, the researchers used many compounds, for example, 2-Ethynylpyrimidine (cas: 37972-24-0Product Details of 37972-24-0).
2-Ethynylpyrimidine (cas: 37972-24-0) belongs to pyrimidine derivatives. The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives. As nucleotides in DNA and RNA, pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Product Details of 37972-24-0
