Background: Angiogenesis is a natural and complex mechanism that is regulated by biomolecules formed by the body. Medicinal inorganic chemistry is increasing in popularity due to metal-based compounds, offering significant chances and possibilities for building novel anti-cancer medicines with promising anti-angiogenic effects.

Objective: This study aimed to examine the successful results obtained from treatments with nanoparticle formulations of active drug substances.

Methods: The nanoprecipitation/solvent displacement approach, with some changes, was used to make PLGA-based NPs.

Result: The particle size obtained in the blank formulation was 82.4-473.9 nm, while the particle size in the API-loaded NPs was 193.2-678.0 nm. Among the formulations, NP-950-P, NP-390-P, and NP-350- CSP2 were found to have significant antioxidant potentials with IC50 values of 3.025, 5.198, and 7.4242 μg.mL-1, respectively, when compared to Vit C. According to the microscopic evaluations, NP-950-P (including Pd(PyCrbx)2Cl2 as 50 μg.pellet-1) and NP-950-CSP2 (including Pd(PyCrbx)2Cl2 as 50 μg.pellet-1) showed strong anti-angiogenic effect whereas the other NP formulations showed weak antiangiogenic effect when compared with the positive control (±)-Thalidomide at the concentration of 50 μg.pellet-1.

Conclusion: When the results were examined, it was found that nanoscale drug carrier systems were prepared, and high antioxidant activity and anti-angiogenesis activity were detected, especially in nanoparticles prepared with 950. As per our knowledge, it is the first study in this field that will bring a new perspective to cancer treatment.
