The Assay of Cyclic AMP in Biological Material,ntrations normally present in most cells and to the presence of other structurally similar compounds in much higher concentrations. With the advent over the last decade of numerous analytical procedures, the investigator is now faced with an almost bewildering choice of assay techniques. It is clear震惊 发表于 2025-3-28 21:49:28

The Actions of Nucleotides on Adenylyl Cyclase Systems,osides. The original finding leading to this recognition (1, 2) was that under stringent assay conditions (using as substrate either low ATP or AMP-PNP) the liver plasma membrane adenylyl cyclase exhibited an almost total requirement for GTP (or ATP) to show activation by glucagon.

Cyclic AMP Metabolism of Some Fibroblastic and Epithelial Cells ,,sine 3′:5′-monophosphate (cyclic AMP) production. Cyclic AMP, in turn, interacts with the regulatory subunits of protein kinase, and also is degraded into 5’-AMP by cyclic nucleotide 3’:5’-phosphodiesterase (phosphodiesterase) (1). For these reasons it is common to use measurements of adenylate cycl机警 发表于 2025-3-29 10:35:01
Metabolism of Cyclic GMP in Vascular Smooth Muscle, Leukocytes, and Lung,clic AMP. Over the almost 20 years that cyclic AMP has been known, the methodology has been consistently improved and refined whereas experience in the extraction, purification and measurement of cyclic GMP from tissues is much less extensive.

Cyclic Nucleotide Analogues,with the biological properties of cyclic AMP has increased rapidly. Then research groups at universities, research institutes and especially in the laboratories of the pharmaceutical industry began to modify cyclic AMP and other cyclic nucleotides systematically.

The Actions of Nucleotides on Adenylyl Cyclase Systems,ems either positively or negatively. They appear to do so by affecting not only the degree of hormonal stimulation, but also the basal activity of the system and the receptor-hormone interaction. We shall review the experimental evidence relating to these effects and discuss the possibility that nucSEMI 发表于 2025-3-30 03:29:00
