Dibutyryl cyclic adenosine monophosphate inhibits pulmonary vasoconstriction
Lung, 1988The effects of the cell-permeable dibutyryl derivative of cyclic AMP on the vascular reactivity of isolated perfused rat lungs were examined. In lungs perfused with homologous blood, pulmonary arterial infusion of db-cAMP (30 micrograms/min) inhibited hypoxia-induced vasoconstriction (IC50 = 6.3 X 10(-5) M) and vasoconstriction due to bolus injection ...

Heterogeneity of antibodies to adenosine 5′-monophosphate
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976Antibodies to adenosine 5'-monophosphate were produced in rabbits by injecting a conjugate of the nucleotide (oxidized with periodate) with bovine serum albumin. AMP-specific antibodies were isolated by affinity chromatography. The antiserum was first applied on oligoadenylic acids-agarose column and then the unbound proteins on a morpholine derivative

Adenosine-5-monophosphate catabolism in frog liver
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19871. AMP catabolism in frog liver extract was found to proceed exclusively through the formation of IMP. Further metabolism of IMP is relatively slow. 2. Among the enzymes involved in AMP catabolism, AMP deaminase is most active and adenosine deaminase and AMP 5'-nucleotidase exhibit only 20 and 10% of AMP deaminase activity respectively.

A chronocoulometric aptamer sensor for adenosine monophosphate
Chemical Communications, 2007The selective recognition of adenosine monophosphate by a half-duplex aptamer-modified electrode leads to a simple chronocoulometric aptasensor based on the changes in surface charges.

Measurement of Plasma Adenosine 3',5'-Monophosphate*
The Journal of Clinical Endocrinology & Metabolism, 1978Currently used methods for plasma cAMP measurements are either tedious (chromatographic preparation of sample) or potentially inaccurate (direct assay of plasma samples). A rapid, simple, and accurate competitive binding assay for plasma cAMP, which does not require chromatographic preparation of the sample, has been developed.

Cyclic Adenosine Monophosphate and Hypertension in Rats
Science, 1973Aortas from spontaneously hypertensive and stress hypertensive rats contained significantly lower intracellular concentrations of cyclic adenosine monophosphate than did their respective controls. Adenylate cyclase activity was normal but was less responsive to stimulation, while phosphodiesterase activity (especially the low Michaelis-Menten constant ...

Cyclic Adenosine Monophosphate (CAMP) and Cyclic Guanosine Monophosphate (CGMP)
Abstract Human physiology is highly dependent on a well-coordinated system of communication between cells. A multitude of external signals, including hormones, neurotransmitters, and other molecules, interact with cells via specific cell-surface receptors.Dominika Lipowska James +1 more
