THE SYNTHESIS AND PROPERTIES OF ADENOSINE-2′ DIPHOSPHATE AND ADENOSINE-3′ DIPHOSPHATE

Canadian Journal of Biochemistry, 1967
Adenosine-2′ diphosphate (A2'DP) and adenosine-3′ diphosphate (A3′DP) have been prepared by reaction between the corresponding mononucleotides with phosphoramidic acid in formamide. The products were isolated by ion-exchange chromatography on DEAE-cellulose and characterized by enzymic and chemical methods. A major side reaction in the synthesis is the

Net adenosine diphosphate accumulation in mitochondria

Archives of Biochemistry and Biophysics, 1977
Abstract In addition to the adenine nucleotide exchange translocator, corn mitochondria possess a transport mechanism for the net accumulation of [3H]ADP. The accumulation is energy linked and requires the presence of phosphate and Mg2+. Inhibition of the adenine nucleotide exchange translocator with carboxyatractyloside does not block ADP ...

Poly(adenosine diphosphate ribose)

1982
Publisher Summary This chapter discusses the higher-order structure of poly(adenosine diphosphate ribose) [poly(ADPR)], poly(ADPR) polymerase purification and its properties, and molecular mechanisms of histone- and elongation-factor (EF-2)-ADP-ribosylation.

Platelet Reaction to Adenosine Diphosphate in vivo

Nature, 1965
ADENOSINE diphosphate (ADP) causes agglutination of human1–3, cat4 and rabbit3,5 platelets in vitro and has also been shown to produce a rapid though transient fall in the number of circulating platelets when injected intravascularly4–6. Born and Cross4 postulated that the intravenous injection of the nucleotide led to a drop in the platelet count ...

Selected cardiovascular effects of adenosine diphosphate

American Heart Journal, 1970
Abstract Six intact dogs were studied before, during, and after an 8 minute infusion of ADP, 0.4 mg./min./Kg. There was a significant decrease in aortic pressure, systemic vascular resistance and platelets, and an increase in cardiac output, central blood volume, stroke volume, heart rate, and pulmonary artery pressure.

Adenosine Diphosphate, Adenosine Triphosphate

1955
The increasing importance for animals and bacteria of adenosine diphosphate (ADP) and adenosine triphosphate (ATP) in energy-transfer mechanisms involving such widely diverse processes as muscular contraction, nerve conduction, fire fly luminescence, coenzyme syntheses, tumor growth, polysaccharide synthesis and many other key reactions (McElroy and ...

Magnesium, Adenosine Diphosphate and Blood Platelets

Nature, 1966
RECENTLY we reported1 a relative plasma magnesium deficiency in a group of forty male patients with acute myocardial infarction (mean of 2.3 mg per 100 ml.) compared with thirty-six normal healthy males (mean of 2.6 mg per 100 ml.) in the same age group. In addition it was shown that magnesium added to fresh whole blood delays the clumping of platelets

Synthesis and characterization of 2'-adenosine diphosphate and 3'-adenosine diphosphate

2011
2'-adenosine diphosphate and 3'-adenosine diphosphate were made from the corresponding unprotected nucleoside monophosphates using phosphoramidic acid. This synthesis of the pyrophosphate link was stimulated by pyridine. Both compounds were more labile than 5'-ADP, and they were shown to degrade by two separate routes.

Poly(adenosine diphosphate ribose)

1973
Publisher Summary This chapter discusses that incorporation of radioactivity of (adenine- 14 C) ATP into the acid insoluble material in a nuclear preparation from hen liver is enhanced at least 1000-fold by the presence of NMN. It is confirmed that this stimulation: using a nuclear preparation from rat liver.
