To study the mutagenicity of the new mutagen, glycidyl methacrylate (GMA). in mam malian cells, the binding between the mutagen and calf thymus DNA in vitro system was investigated. By using absorption spectrum shift method, it was found that the λmax 202 nm of DNA and λmax 208 nm of GMA shifted by more than 15nm toward longer wave length with decreased absorption intensity af ter the incubation at room temperature for 15 minutes or more. The results indicated that the binding between GMA and...

To study the mutagenicity of the new mutagen, glycidyl methacrylate (GMA). in mam malian cells, the binding between the mutagen and calf thymus DNA in vitro system was investigated. By using absorption spectrum shift method, it was found that the λmax 202 nm of DNA and λmax 208 nm of GMA shifted by more than 15nm toward longer wave length with decreased absorption intensity af ter the incubation at room temperature for 15 minutes or more. The results indicated that the binding between GMA and DNA occured. The binding force of GMA to DNA was strong and not affected by sodium chloride even at high concentration. It was slightly decreased in the presence of 8M urea. These results revealed that an ionic binding or hydrogen-bond binding between GMA and DNA is un likely, so it was considered to be a covalent bond binding.

运用吸收光谱移动法观察到甲基丙烯酸环氧丙酯Glycidyl Mcthacrylate,GMA与哺乳类基因组DNA具有强的结合作用。GMA浓度在0—2.8mmol/L范围内,DNA的吸收光谱随GMA浓度的增加而增加了向长波方向位移,并伴随吸收强度降低。若固定GMA浓度,改变DNA浓度,GMA吸收光谱也出现与上类似现象。实验还表明GMA与DNA的结合键型为共价型。

The authors explored the mechanism of porous β--TCP/HA biphase ceramic-induced osteogenesis in vitro.The capabicities of porous β--TCP/HA biphase ceramic to absorb bone morphogrnetic protein (BMP) were studied. Porous β--TCP/HA biphase ceramics absorb BMP by both bond--binding and physical absorption.In chemical absorption (bond--binding), the calcium of HA[Ga10(OH)2 (PO4)6] binds the carboxy1 group of BMP. During the ceramic--induced osteogenesis, β-TCP [βCa3(PO4)2] provides the...

通过体外实验,确定了骨形成蛋白因子BMP在多孔磷灰石陶瓷上的吸附位点,以及两者之间的吸附性能.在β-磷酸三钙/羟基磷灰石(β-TCP/HA)双相多孔磷灰石陶瓷诱导成骨中,HA为宿主骨及β-TCP降解提供钙、磷源的成骨机制.这些实验结果有助于增进对羟基磷灰石骨修复材料成骨作用的了解,并能较好地解释β-TCP/HA双相磷灰石陶瓷在体内非骨环境中的诱导成骨作用.

Comparative molecular field analysis of 3 (4 cholorbenzylamino) 2 cyano 3 alkyl acrylate inhibitors was studied. It was found that the side chain of ester might be a H bond binding area, and the stereo character of 3 alkyl is important for bioactivity of compounds.

在除草剂的分子设计中,抑制光合作用除草剂的研究一直受到极大的关注.其中,氰基丙烯酸酯类化合物对光合作用中电子传递(即希尔反应)抑制活性较高[1,2].研究表明,这类化合物在结构上的细微变化对希尔反应抑制活性的影响均很显著.因此,对这类抑制剂进行系统的...
