摘要: 合成了光敏基团位于sn-1脂肪酰基上的光亲和标记磷脂酸(PA)类似物,选用了有较高C-H插入效率的全氟苯基叠氮化合物作为光敏基团.用酶化学方法在PA类似物中引入了同位素标记33P.初步实验表明,合成的PA类似物与天然PA一样对cAMP-磷酸二酯酶有激活作用,提示合成的PA类似物可进一步用于该酶的光亲和标记.

Abstract: Phosphatidic acid(PA)analogue for photoaffinity labeling was synthesized,which beats the photoactivable group on the sn 1 fatty acyl chain.The perfluorophenyl azide was selected as photoactivable group for it gaving more C-H insertion than that of nonfluorinated analogues.Isotope 33P was introduced into the PA analogue by enzymatic method.Primary test showed that the PA analogue was as efficient as naturally occurring PA in activating cAMP phosphodiesterases,suggesting that it could be proper candidate for farther enzymatic photoaffinity labeling.

Key words: photoaffinity labeling, phosphatidic acid, synthesis
