Pharmacokinetic Tuning Redirects β‐Lapachone From NQO1 Bioactivation to Vimentin‐Targeted Oxidation in Cancer

open access: yesAdvanced Science, EarlyView.
Pharmacokinetic tuning acts as a programmable mechanistic switch for β‐lap. Sustained low‐concentration exposure redirects β‐lap from NQO1 bioactivation to direct oxidation of vimentin, driving disulfide crosslinking, proteasomal overload and ferroptosis.

Multi‐Property Machine Learning Models to Accelerate the Transition Toward Bio‐Based Emulsion Polymers

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...
