Controllable Carbon-Increasing Homologation of Electron-Deficient Alkenes via a Sew-and-Cut Strategy

This paper reports a photoinduced "sew-and-cut" strategy that enables controllable, tunable carbon-increasing homologation of electron-deficient alkenes by utilizing cycloalkyl hydroperoxides as carbon sources to directly insert (CH₂)ₙ units (n = 1–8) through a sequence of radical-mediated C–C bond cleavage, Giese-type addition, and Norrish type II reaction.

Human Myeloperoxidase-Driven Activation of Skin Sensitizing p-Phenylenediamine-related Aromatic Diamines and Phenylpropanoids – Insights from In Chemico and In Silico Approaches

This study demonstrates that human myeloperoxidase (MPO), released by neutrophils during skin sensitization, enzymatically oxidizes specific aromatic diamines and phenylpropanoids into protein-reactive metabolites, thereby revealing a previously unrecognized biological activation pathway that complements existing abiotic and epidermal metabolic mechanisms.
