β‐galactosidase‐responsive molecular “Trojanhorse” was designed to selectively kill folate receptor‐positive tumorcells. The recognition of the folate membrane receptor is followed by the internalization and the subsequent enzymatic activation of the targeting assembly to release the cytotoxic agent in a stringently controlled fashion exclusively inside the targetedcells.
The rise of chemical biology has led to the development of sophisticated molecular devicesdesigned to explore and manipulate biological processes. Within this framework, we developed the first chemicalsystem programmed for the selective internalization and subsequent enzyme-catalyzed double release of bioactive compounds inside a targeted population of cells. This system is composed of five distinct

for reliableregulation of vascular senescence through hierarchicalrecognition of three types of senescence-related hallmarks. It can actively target and trigger cell-specific apoptosis in senescent endothelial cells caused by various stimuli, while keeping silent in non-senescent cells, contributing to effective inhibition effects on the senescence burden-induced progress of atherosclerosis.
