Purpose of the Study:
- To synthesize and characterize a novel dinuclear platinum(II) complex, di-DACH-Pt(II).
- To create a polymer-based micelle formulation, M(di-DACH-Pt), for enhanced drug delivery.
- To evaluate the in vivo systemic toxicity and antitumor efficacy of the M(di-DACH-Pt) micelles.
Main Methods:
- Synthesis and characterization of the dinuclear platinum(II) complex (di-DACH-Pt(II)).
- Tethering of di-DACH-Pt(II) to a biodegradable, amphiphilic copolymer.
- Preparation and characterization of the polymer-based micelle formulation (M(di-DACH-Pt)).
- Assessment of systemic toxicity and antitumor efficacy in relevant models.
Main Results:
- Successful synthesis and characterization of the di-DACH-Pt(II) complex.
- Formation of stable M(di-DACH-Pt) micelles.
- M(di-DACH-Pt) micelles exhibited significantly reduced systemic toxicity compared to the parent complex.
