The binding interaction of novel podophyllotoxin derivative, (3R,4R)-4-((benzo[d][1,3]dioxol-5-yl)methyl)-dihydro-3-(hydroxy(3,4-dimethoxyphenyl) methyl) furan-2(3H)-one (PPT), with calf thymus DNA (ctDNA) has been examined using UV-Visible absorption spectrophotometry, fluorescence spectroscopy, viscosity measurement and molecular docking studies. UV-Vis absorption results showed hyperchromic ...
