Abstract:
:Tumor hypoxia has been widely explored over the years as a diagnostic and therapeutic marker. Herein, we designed, optimized and synthesized a new multifunctional bioreductive linker (12) containing an alkynyl group (potential click chemistry fragment); the linker is based on 2-nitroimidazole which was expected to simultaneously overcome the drawbacks of hypoxia-activated prodrugs (poor selectivity and unsatisfactory water solubility). Furthermore, a hypoxia-activated, water-soluble SN-38 prodrug was obtained, and it was stable under physiological conditions and was rapidly released as an active drug under hypoxic conditions.
