Competitive cAMP antagonists for cAMP-receptor proteins.
The two exocyclic oxygen atoms at phosphorus of cAMP have been replaced by a sulfur atom or by a dimethylamino group. These substitutions introduce chirality at the phosphorus atom; therefore, two diastereoisomers are known for each derivative: (SP)-cAMPS, (RP)-cAMPS, (SP)-cAMPN(CH3)2, and RP-cAMPN(CH3)2. We have investigated the agonistic and antagonistic activities of these compounds in four ...
متن کاملcAMP-dependent protein kinase activation lowers hepatocyte cAMP.
Rat hepatocyte protein kinase was activated by incubating the cells with various cAMP analogs. Boiled extracts were then prepared and Sephadex G-25 chromatography was carried out. The G-25 procedure separated the analogs from cAMP since the resin had the unexpected property of binding cyclic nucleotides with differing affinities. Separation was necessary because the analogs would otherwise inte...
متن کاملUnderpinning compartmentalised cAMP signalling through targeted cAMP breakdown.
It is becoming increasingly apparent that spatial regulation of cell signalling processes is critical to normal cellular function. In this regard, cAMP signalling regulates many pivotal cellular processes and has provided the paradigm for signal compartmentalization. Recent advances show that isoforms of the cAMP-degrading phosphodiesterase-4 (PDE4) family are targeted to discrete signalling co...
