应用光谱法研究了手性金属配合物[Fe(phen)_3] ̄(2+)与小牛胸腺DNA的作用,确定了△型异构体对B型右手螺旋DNA有优先键合的立体选择性.
The effect of the chiral metal complex [Fe (phen) 3] 2+ on calf thymus DNA was studied by spectroscopy and the stereoselectivity of the preferential bonding of the Δ isomer to the B-type right-handed helical DNA was determined .
