N6-Monoalkylated, N6-dialkylated and N6-acylated (RP)-adenosine 3′,5′-cyclic phosphorothioic acids have been prepared by stereoselective syntheses from cAMP for a study of protein kinase A antagonist activity. The antagonist activity of the parent primary 6-amino cAMP derivative was reduced after N-monoalkylation. No significant activity was detected in the N,N-dialkylated derivative. Mono N-acylation
Ñ 6单烷基化,Ñ 6二烷基化和Ñ 6 -acylated([R P)腺苷3',5'-环硫代磷酰氨基酸被由来自cAMP的立体选择性合成的蛋白质的研究激酶A拮抗剂活性。N-单烷基化后母体伯6-氨基cAMP衍生物的拮抗活性降低。在N,N-二烷基化衍生物中未检测到显着活性。单N-酰化作用对活性影响很小。涉及cAMPS中6-氨基的氢键似乎是活性所必需的。
