The interaction of isoxazolcurcumin (IOC), a synthetic derivative of curcumin, with calf thymus-DNA (ct-DNA) has been investigated by UV-Vis, fluorescence, circular dichroism spectroscopies, viscosity measurements and docking studies. From these analyses, the binding constant, number of binding sites and mode of binding of IOC to ct-DNA has been determined.(More)
The interaction of bovine serum albumin (BSA) with isoxazolcurcumin (IOC) and diacetylcurcumin (DAC) has been investigated. Binding constants obtained were found to be in the 10(5) M(-1) range. Minor conformational changes of BSA were observed from circular dichroism (CD) and Fourier transformed infrared (FT-IR) studies on binding. Based on Förster's theory(More)
The interaction of copper complexes of (-)-epicatechin gallate (ECG) and (-)-epigallocatechin gallate (EGCG) with calf thymus DNA (ct-DNA) was investigated by UV-visible (UV-Vis), fluorescence and circular dichroism along with melting studies. It was observed that both copper complexes quench the fluorescence intensity of ethidium bromide bound ct-DNA upon(More)
Curcumin is a nontoxic natural product with diverse pharmacological potencies. We report the interaction of a potent synthetic derivative of curcumin, isoxazolcurcumin (IOC) with human serum albumin (HSA) using various biophysical methods. The observed fluorescence quenching of HSA by IOC is due to a complex formation by a static quenching process with a(More)
Binding studies of 3'-O-carboxy esters of thymidine, reported inhibitors of ribonucleases, with bovine serum albumin (BSA) have been explored in this report. Fluorescence spectroscopy in combination with Fourier transform infrared (FTIR) and circular dichroism (CD) spectroscopy have been used to determine the nature and mode of binding. The binding and(More)
Curcumin is a natural product with diverse pharmacological activities. Studies of curcumin and its structural derivatives have been a subject of growing interest as a result of their diverse biological activities. We report the interaction of diacetylcurcumin (DAC) with Ribonuclease A (RNase A). The binding constant of DAC with RNase A was found to be of(More)
