The binding characteristics of human serum albumin (HSA) with N-alkyl phenothiazines derivatives (NAP) viz., levomepromazine monomaleate (LMM) and propericiazine (PPC) have been studied by employing fluorescence, absorption, circular dichroism and FT-IR techniques. The Stern-Volmer quenching constant, K(SV) values were found to decrease with increase in(More)
The interaction between triprolidine hydrochloride (TRP) to serum albumins viz. bovine serum albumin (BSA) and human serum albumin (HSA) has been studied by spectroscopic methods. The experimental results revealed the static quenching mechanism in the interaction of TRP with protein. The number of binding sites close to unity for both TRP-BSA and TRP-HSA(More)
The binding of carbamazepine (CBZ) to human serum albumin (HSA) was investigated under simulative physiological conditions. In this study, intrinsic fluorescence of tryptophan-214 in HSA was monitored upon the addition of CBZ. Binding constant of CBZ-HSA was calculated by the remarkable static quenching effect of CBZ and found to be(More)
Adsorption or immobilization of proteins on solid surfaces promotes the biological responses to materials. Using immobilization technique, we have prepared human serum albumin (HSA) modified glassy carbon electrode (GCE) and employed it to probe the mode of interaction between antidepressant drug, buzepide methiodide (BZP) and HSA. At HSA modified GCE, the(More)
The binding of coomassie brilliant blue G (CBB) to bovine serum albumin (BSA) was investigated under simulative physiological conditions employing different optical spectroscopic techniques viz., fluorescence emission, UVâvisible absorption and FTIR. Fluorescence quenching data obtained at different temperatures suggested the presence of dynamic type of(More)
In the present study, a DNA-biosensor was prepared using immobilization technique to investigate the interaction between an antidepressant, buzepide methiodide (BZP) and calf thymus DNA. BZP showed a quasireversible peak in Britton-Robinson (BR) buffer of pH 5 at bare glassy carbon electrode (GCE). At DNA modified GCE, the peak potential of BZP was observed(More)
The interaction between human serum albumin (HSA) and fluoxetine hydrochloride (FLX) have been studied by using different spectroscopic techniques viz., fluorescence, UV-vis absorption, circular dichroism and FTIR under simulated physiological conditions. Fluorescence results revealed the presence of static type of quenching mechanism in the binding of FLX(More)
In this work, we have prepared nano-material modified carbon paste electrode (CPE) for the sensing of an antidepressant, buzepide methiodide (BZP) by incorporating TiO2 nanoparticles in carbon paste matrix. Electrochemical studies indicated that the TiO2 nanoparticles efficiently increased the electron transfer kinetics between drug and the electrode.(More)
