Fabrication and appraisal of axitinib loaded PEGylated spanlastics against MCF- 7 and OV- 2774 cell lines using molecular docking methods and in-vitro study
Abstract
Axitinib is a second-generation tyrosine kinase inhibitor that works by selectively inhibiting vascular endothelial growth factor receptors (VEGFR-1, VEGFR-2, VEGFR-3). Through this mechanism of action, axitinib blocks angiogenesis, tumor growth and metastases and therefor it shows significant promise as a chemotherapeutic agent for various types of cancer. Nevertheless, the clinical efficacy of this substance is hindered by its restricted solubility in water and inadequate stability. To address these challenges, we developed spanlastics with polyethylene glycol (PEG) to improve the efficacy and stability of axitinib against breast and ovarian tumor malignancies in a targeted manner. Moreover, the study conducts a thorough examination of the interactions between the ligand Axitinib alone or after coating with PEG and a diverse array of protein types in breast (Dopamine, VEGFR) and ovarian cancer (EGFR, BCL-xL). The fabrication of axitinib- spanlastics was achieved through a thin-film hydration method. The evaluation of the impact of formulation factors on the features of nanovesicles was conducted using the I- optimal design. Subsequently, the optimum formulation was calculated. The optimal formulation was coated with polyethylene glycol (axitinib-PEG-spanlastics). An in vitro assessment was computed to evaluate the efficiency of the optimized axitinib-PEG-spanlastics against the MCF-7 breast cancer cell line and the OV-2774 ovarian cancer cell line. The optimized…
