Kev sib cuam tshuam ntawm cov tshuaj tiv thaiv kab mob ntshav qab zib, Metformin thiab calf thymus DNA (CT-DNA) hauv (50mM Tris-HCl) tsis tau raug kawm los ntawm UV-Visible absorption, fluorescence, CD spectroscopy thiab ntsuas viscosity.Hauv kev tshawb fawb fluorimetric, enthalpy thiab entropy ntawm cov tshuaj tiv thaiv ntawm cov tshuaj thiab CT-DNA qhia tau hais tias cov tshuaj tiv thaiv yog exothermic (ΔH = -35.4522 kJ mol(-1); ΔS = -49.9523 J mol(-1)K(-1) )).Cov kev tshawb fawb sib tw sib tw tau pom tias cov tshuaj tuaj yeem tso tawm Hoechst 33258 tag nrho.Lub complex pom tias nqus hyperchromism hauv nws UV-Vis spectrum nrog DNA.Qhov ntsuas qhov txuas tas mus li, K(b), tau los ntawm UV-Vis absorption kev tshawb fawb yog 8.3 × 10 (4) M (-1).Ntxiv mus, cov kev hloov hauv CD spectra nyob rau hauv lub xub ntiag ntawm cov tshuaj qhia stabilization ntawm txoj cai B daim ntawv ntawm CT-DNA.Thaum kawg, kev ntsuas viscosity tau qhia tias kev sib khi ntawm cov complex nrog CT-DNA tuaj yeem yog qhov sib khi, feem ntau yog vim qhov sib khi khi.Copyright © 2012 Elsevier BV All rights reserved.
