ABSTRACT
Artificial organelles (AOs) encapsulating enzymes are engineered to facilitate biocatalytic reactions for exerting therapeutic effects in various diseases. Exploiting the confinement effect, these catalytic properties exhibit significant enhancements without being influenced by the surrounding medium, enabling more efficient cascade reactions. In this study, we present a novel approach for synergistic tumor starvation therapy by developing multicomponent artificial organelles that combine enzymatic oncotherapy with chemotherapy. The construction process involves a microfluidic-based approach that enables the encapsulation of cationic cores containing doxorubicin (DOX), electrostatic adsorption of cascade enzymes, and surface assembly of the protective lipid membrane. Additionally, these multicomponent AOs possess multicompartment structures that enable the separation and sequential release of each component. By coencapsulating enzymes and chemotherapeutic agent DOX within AOs, we achieve enhanced enzymatic cascade reactions (ECR) and improved intrinsic permeability of DOX due to spatial confinement. Furthermore, exceptional therapeutic effects on 4T1 xenograft tumors are observed, demonstrating the feasibility of utilizing AOs as biomimetic implants in living organisms. This innovative approach that combines starvation therapy with chemotherapy using multicompartment AOs represents a promising paradigm in the field of precise cancer therapy.
