Radiation‐Responsive Benzothiazolines as Potential Cleavable Fluorogenic Linkers for Drug Delivery

Abstract

AbstractRadiosensitive compounds can be useful for the detection of radiations and also as prodrugs that can be activated during a radiotherapy. Herein we describe the use of benzothiazolines, which upon treatment with 137Cs produced γ‐irradiation in water give rise to fluorescent benzothiazoles and concomitant release of amines or carboxylic acids. In a proof of concept study, we showed that benzothiazolines may be used as new cleavable linkers that can be triggered upon irradiation.
