Acid-triggered release of doxorubicin from a hydrazone-linked Gd3+-texaphyrin conjugate†
Abstract
The hydrazone-based Gd3+-texaphyrin doxorubicin conjugate 1, releases active doxorubicin at acidic pH values, allowing its components to be followed by two complementary imaging methods, namely Off–On fluorescence enhancement and MR imaging. It thus acts as a promising theranostic agent.
