Investigation of the Interaction of Sertraline with Calf Thymus DNA by Spectroscopic Methods
نویسندگان
چکیده
A interação entre a droga anti-depressiva, sertralina, com o DNA de fita dupla (dsDNA) de timo de vitelo em tampão fisiológico (pH 7,4) foi determinada por espectrofotometria de UV-Vis, espectrofluorimetria, dicroísmo circular, espectroscopia no infravermelho com transformada de Fourier (FTIR), medições da viscosidade e estudos de fusão de DNA. Os espectros de absorção da droga com o DNA mostraram um efeito hipercrômico. Ao usar o reagente Hoechst como uma sonda de fluorescência ocorreu a extinção do pico de emissão na mistura DNA-Hoechst após a adição da sertralina. Os espectros de FTIR revelaram o modo de ligação de menor sulco entre o fármaco e o dsDNA. A constante de ligação da sertralina ao DNA foi calculada utilizando os dados espectroscópicos. Os parâmetros termodinâmicos calculados sugeriram que as interações eletrostáticas são forças importantes na formação do complexo DNA-sertralina.

The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...
