摘要:氨基氯化铵和胍基氯化铵均用于利用"t2弛豫水衰减"(watr)技术在80兆赫1H核磁共振谱中抑制水信号.在80兆赫下,磷酸盐缓冲液对抑制效果的影响在一系列ph值下进行了研究.发现在存在0.1摩尔磷酸盐缓冲液和1摩尔胍基氯化铵的条件下,80兆赫下水质子的自旋-自旋弛豫时间在ph 7.3时达到最小值;因此,这些条件被选择用于后续使用watr技术研究新斯的明溴化物水解动力学.该方法被发现非常适用于研究这种代表性酰胺的水解过程.

标 题 :Method for the synthesis of pyrrole and imidazole carboxamides on a solid support
发明人：DERVAN PETER B; BAIRD ELDON
权利人:CALIFORNIA INST OF TECHN
摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.
