DYSP-C34, a potent ultrasound (US)-triggered multifunctional molecular machine, exhibits a favorable lipophilic/hydrophilic balance, enhanced US-induced reactive oxygen species (ROS) production, and improved cellular permeability. These properties contribute to its superior tumor-targeting efficiency and significant tumor regression when used in sonodynamic therapy (SDT). Additionally, DYSP-C34 demonstrates mild immunogenicity by directly stimulating antigen-presenting cells (APCs) [1].
