الوصف: Immunogenic cell death (ICD) can activate the anticancer immune response and is highly attractive to improve cancer treatment efficacy. ICD is closely related to endoplasmic reticulum (ER) stress, and a series of ICD inducers has recently been reported based on ER-targeted photodynamic/photothermal agents or metal complexes. However, these ER-targeted ICD inducers suffer from complicated synthesis and heavy-metal cytotoxicity. Inspired by the promising clinical potential of small organic molecules, herein, an ER-targeted fluorescent self-reporting ICD inducer, SA-Cbl, is developed by simple conjugation of the chemotherapeutic drug chlorambucil (Cbl) with salicylaldehyde (SA). SA-Cbl can selectively accumulate in the ER to induce rapid ROS generation and an unfolded protein response process, which leads to a fast release of damage-associated molecular patterns and efficient dendritic cells maturation. Meanwhile, the ER-targeted accumulation and ER-stress-inducing process can be in situ monitored based on the turn-on fluorescence of SA-Cbl, which is highly pH- and polarity-sensitive and can selectively interact with ER proteins. Compared with the traditional chemotherapy drug doxorubicin, the superior anticancer immunity effect of SA-Cbl is verified via an in vivo tumor model. This study thus provides a new strategy for developing fluorescent self-reporting ICD inducers by decoration of chemotherapeutic drugs with pH and polarity-sensitive organic fluorophores.
