Abstract

Passive diffusion does not explain why many drugs are too large and/or too polar for rule-breaking membrane penetration, such as proteolysis-targeting chimeras (PROTACs, generally of a molecular weight > 800 Da). Here, using biotinylated chemical-probe-based target fishing and genetic knockdown/knockin approaches, we discovered that the membrane cluster of differentiation 36 (CD36) binds to and facilitates the uptake and efficacy of diverse PROTACs (e.g., SIM1-Me, MZ1, and clinical ARV-110) and large and/or polar small-molecule drugs (e.g., rapalink-1, rapamycin, navitoclax, birinapant, tubacin, and doxorubicin) via the CD36-mediated early endosome antigen 1 (EEA1)/Ras-related protein 5A (Rab5) endosomal cascade in vitro and/or in vivo. We then devised a novel chemical endocytic medicinal chemistry strategy to improve binding of PROTACs to CD36 using structural modifications via the prodrug approach, markedly enhancing PROTAC anti-tumor efficacy through spontaneously augmenting permeability and solubility.

期刊介绍： Cells is an international, peer-reviewed, open access journal that focuses on cell biology, molecular biology, and biophysics. It is affiliated with several societies, including the Spanish Society for Biochemistry and Molecular Biology (SEBBM), Nordic Autophagy Society (NAS), Spanish Society of Hematology and Hemotherapy (SEHH), and Society for Regenerative Medicine (Russian Federation) (RPO). The journal publishes research findings of significant importance in various areas of experimental biology, such as cell biology, molecular biology, neuroscience, immunology, virology, microbiology, cancer, human genetics, systems biology, signaling, and disease mechanisms and therapeutics. The primary criterion for considering papers is whether the results contribute to significant conceptual advances or raise thought-provoking questions and hypotheses related to interesting and important biological inquiries. In addition to primary research articles presented in four formats, Cells also features review and opinion articles in its "leading edge" section, discussing recent research advancements and topics of interest to its wide readership.
