The present disclosure provides compositions and methods for selectively killing senescent cells, wherein the composition comprises piperlongumine (PL) or derivative thereof. The selective killing of senescent cells may delay aging and/or treat age-related disorders.
olefin with an exocyclic methylene at C2 render PL analogues 47–49 with increased senolytic activity. These α-methylene containing analogues are also more potent than PL in inducing ROS production in WI-38 SCs. Similar to PL, 47–49 reduce the protein levels of oxidation resistance 1 (OXR1), an important oxidative stress response protein that regulates the expression of a variety of antioxidant enzymes

3-methylene 2-pyrrolidinone 1 ylide-lactame 6 is reported. Diels-Alder cycloadditions of 1 to cyclopentadiene exhibited very high exoselectivities, regardless of the experimental conditions. These results confirm the generality of exoselectivity for conformationally restricted s-cis dienophiles and indicate that the dienophile functionality and dipole moment have little influence on its magnitude.

reaction of targeted covalent inhibitors with nucleophilic residues in protein active sites. Herein, we present thiol reactivity studies that support α-methylene-γ-lactams as tunable surrogates for the highly reactive α-methylene-γ-lactones. The reactivity of the α-methylene is modulated via the N substituent, and the reaction rates toward glutathione were determined via mass spectrometry. Density

is readily polymerized via conventional free radical polymerization, and two reversible deactivation radical polymerization methods including reversible addition–fragmentation (chain) transfer and single-electron-transfer living radical polymerization. Poly(3M2P) has a high thermal stability and a very high glass transition temperature. Poly(3M2P) does not dissolve in most common organic solvents, but
