Isocyanate-Modified Melatplatin(IV) Enhances Antitumor Efficacy via TCF4/COL6A3-Mediated Extracellular Matrix Remodeling and cGAS-STING Pathway Activation in Bladder Cancer. [PDF]

open access: yesAdv Sci (Weinh)
A series of melatonin‐conjugated platinum(IV) prodrugs was functionalized with isocyanate chains (compounds 5‒12). MP‐12C (compound 11) was identified as the lead candidate, with optimal potency and safety. MP‐12C exhibited greater efficacy than cisplatin by increasing intracellular uptake, reshaping the extracellular matrix, activating the cGAS‐STING ...
