A PREFORMULATION STUDY ON INTERACTIONS BETWEEN DOXORUBICIN HYDROCHLORIDE AND BOVINE SERUM ALBUMIN
International Journal of Applied Pharmaceutics
Objective: The objective was to study the effect of concentrations of doxorubicin hydrochloride (Dox) and bovine serum albumin (BSA) in a sample on fluorescence intensity, UV absorbance, refractive index and optical rotation.Methods: A circumscribed central composite statistical design with 2 factors, 5 levels, and 13 runs was selected for the study. According to that influence of both in interaction was measured by fluorescence intensity, UV absorbance, refractive index and optical rotation
... optical rotation and were analyzed by the design expert software.Results: It was observed that concentration of BSA alone was significantly affecting the fluorescence intensity and optical rotation of samples. Dox alone was having a significant effect on UV absorbance at 280 nm. In the case of a refractive index, both Dox and BSA were having a significant effect. But the effect of BSA was much pronounced than that of Dox on refractive index.Conclusion: Interaction studies between BSA and Dox would be beneficial as they are commonly used in combination with tumor-targeted delivery. The interaction was observed that in a linear model for a wide range of concentration of both. So it will be useful to determine the interaction of unknown concentration.
