研究了一系列26种3-羟基色酮,三种双黄酮醇和四种3-羟基喹诺酮,以评估它们在缓冲液中对与ATP相互作用的荧光响应。染料的总电荷,芳族单元的大小和数量以及其取代基的位置或给电子能力不同。建议所有这些化合物都形成化学计量比为1:1和1:2的ATP的复合物,这可以通过其明亮的荧光和其3000-6000 cm -1的红移激发带来证明。这些荧光复合物可以检测超过3个数量级的ATP浓度,而大多数其他已知的探针覆盖的数量最多不超过2个数量级。总体而言,这些染料可以检测0.001至57 m m的ATP。此外,大多数染料-ATP络合物都可以在可见光中被激发,并在光谱的红色区域中被监测。所描述的染料对ATP的响应幅度与最知名的探针一样高。考虑到络合发生在中性pH值下,所研究的染料形成了荧光探针工具箱,用于在较宽的浓度范围内对ATP浓度进行强度和比率测量。最后,获得的结果激发了这样的想法,即活细胞中的大多数天然3-羟基黄酮可能与ATP形成复合物。
Herein we report a feasible study concerning the design, syntheses and in vitro antimicrobial and antitumoral
activities of some novel compounds with dihydroxyacetophenone (DA) moiety. An efficient and general method for the
preparation of diazine with dihydroxyacetophenone (DDA) skeleton under conventional thermal heating (TH), microwave
(MW) and ultrasounds (US) irradiation is presented. Antimicrobial and antitumoral tests prove that some dihydroxyacetophenone
compounds (the brominated derivatives BrDA 3) have a significant biological activity. It is also to be pointed out
that, basically all the dihydroxyacetophenone derivatives proved to have a powerful antibacterial activity against drug resistant
Gram-negative strain Pseudomonas aeruginosa ATCC 27853. Of particular interest could be the excellent antibacterial
activity of our dihydroxyacetophenone compounds against drug resistant Gram-negative strain Pseudomonas aeruginosa.

complexes allow detection of ATPconcentrations over 3 orders of magnitude, whereas most other known probes cover no more than two orders. In total, the dyes allow ATP detection from 0.001 to 57 mm. In addition, most of the dye–ATP complexes can be excited in the visible and monitored in the red region of the spectrum. The response amplitude of the described dyes to ATP is as high as for the best known
