Abstract:
The interaction between Ketaconazole (KTZ) an
anti-fungal drug, and Bovine serum albumin (BSA) was
investigated by voltammetric methods such as cyclic and
Differential Pulse Voltammetry and different
spectroscopic methods such as UV/visible
spectrophotometry, spectroflourimetry and viscometric
method were used to study the process. The voltammetric
study of KTZ on GCE, the anodic peak was appeared at
0.667 V versus SCE corresponding peak current is
-2.202×10-6A. The anodic peak currents were drastically
decreased in the presence of BSA. The peak potential
shift towards negative direction in CV and DPV suggested
an electrostatic interaction, whereas Fluorescence
spectra suggested that the quenching mechanism of the
interaction of BSA to KTZ was a static quenching type.
By the analysis of UV/Vis spectra, it was observed that
KTZ had a high affinity with BSA which was indicated by
the large binding constant.
