Abstract

Effect of millimeter range electromagnetic waves (MM EMW) with the frequency 51.8 GHz on the interaction of DNA-specific ligands-intercalators acridine orange (AO) and methylene blue (MB) with bovine serum albumin (BSA) has been studied. The measurements were implemented by the spectroscopic methods that open new opportunities for such goals. The methods of absorption, differential and fluorescence spectroscopies were applied. The obtained data permit revealing several peculiarities of MM EMW effect on the interaction of these ligands with BSA, as well as possible sites and modes for the binding. AO and MB were found out to bind to BSA by two modes, moreover, under the effect of MM EMW, one of these modes for MB disappears. The values of the quenching constant - KSV were determined for the types that compose 4.7⋅104 and 9.2⋅104 L/mole for non-irradiated and 4.6⋅104 and 11.0⋅104 L/mole for irradiated complexes AO-BSA, respectively. For the non-irradiated complexes MB-BSA the values of KSV were equal to 4.0⋅104 and 0.87⋅104 L/mole, respectively. Because of the irradiation, the first type of the binding disappears, while for the second type the value 0.43⋅104 L/mole was obtained. It was also revealed that MM EMW invokes structural transformations in BSA molecule that touch those sites to which AO and MB bind. Moreover, for AO it results in an increase of preferable binding to this site; though, for MB, vice versa, it leads to the disappearance of stronger (specific) binding mode, while the electrostatic interaction appears for both non-irradiated and irradiated protein.

毫米波作用下牛血清白蛋白与吖啶橙和亚甲基蓝配合物光谱特性的比较研究。
研究了51.8 GHz毫米波(MM EMW)对dna特异性配体吖啶橙(AO)和亚甲基蓝(MB)与牛血清白蛋白(BSA)相互作用的影响。这些测量是通过光谱方法实现的,为实现这一目标开辟了新的机会。采用了吸收光谱、微分光谱和荧光光谱等方法。所获得的数据揭示了MM - EMW对这些配体与BSA相互作用的影响的几个特点,以及可能的结合位点和模式。发现AO和MB以两种模式与BSA结合,且在MM - EMW的作用下,MB的其中一种模式消失。测定了未辐照AO-BSA为4.7⋅104和9.2⋅104 L/mol、辐照AO-BSA为4.6⋅104和11.0⋅104 L/mol的配合物的猝灭常数KSV值。未辐照配合物MB-BSA的KSV值分别为4.0⋅104和0.87⋅104 L/mol。由于辐照作用,第一类结合消失,第二类结合值为0.43⋅104 L/mol。研究还发现,MM - EMW可引起BSA分子的结构转化,从而触及AO和MB的结合位点。此外,对于AO,它导致与该位点的良好结合增加;然而,对于MB,反之亦然,它会导致更强(特异性)结合模式的消失,而对于未辐照和辐照的蛋白质都出现静电相互作用。
