Abstract:
:The objective of this research was to develop polymeric micellar formulations of inhibitors of signal transducer and activator of transcription 3 (STAT3) dimerization, i.e., S3I-1757 and S3I-201, and evaluate the activity of successful formulations in B16-F10 melanoma, a STAT3 hyperactive cancer model, in vitro and in vivo. STAT3 inhibitory agents were encapsulated in methoxy poly(ethylene oxide)-b-poly(ε-caprolactone) (PEO114-b-PCL22) and methoxy poly(ethylene oxide)-b-poly(α-benzyl carboxylate-ε-caprolactone) (PEO114-b-PBCL20) micelles using co-solvent evaporation. Polymeric micelles of S3I-1757 showed high encapsulation efficiency (>88%), slow release profile (<32% release in 24 h) under physiological conditions, and a desirable average diameter for tumor targeting (33-54 nm). The same formulations showed low encapsulation efficiencies and rapid drug release for S3I-201. Further studies evidenced the delivery of functional S3I-1757 by polymeric micelles to B16-F10 melanoma cells, leading to a dose-dependent inhibition of cell growth and vascular endothelial growth factor (VEGF) production comparable with that of free drug. Encapsulation of S3I-1757 in polymeric micelles significantly reduced its cytotoxicity in normal bone marrow-derived dendritic cells (DCs). Micelles of S3I-1757 were able to significantly improve the function of B16-F10 tumor-exposed immunosuppressed DCs in the production of IL-12, an indication for functionality in the induction of cell-mediated immune response. In a B16-F10 melanoma mouse model, S3I-1757 micelles inhibited tumor growth and enhanced the survival of tumor-bearing mice more than free S3I-1757. Our findings show that both PCL- and PBCL-based polymeric micelles have potential for the solubilization and delivery of S3I-1757, a potent STAT3 inhibitory agent.
