Abstract
Abstract The fluorescent 1, N 6 -ethenoadenosine derivatives of adenosine triphosphate, adenosine diphosphate, adenosine monophosphate, 3′:5′-cyclic adenosine monophosphate, adenosine and nicotinamide adenine dinucleotide have been prepared. Paper and thin layer chromatographic purification methods have been developed. Nuclear magnetic resonance and mass spectrum data indicate that only the purine ring has been modified. The 1, N 6 -ethenoadenosine triphosphate had about 70% of the activity of adenosine triphosphate as a substrate for total adenosine triphosphatase activity of hypophysectomized rat liver membranes. The 1, N 6 -ethenoadenosine diphosphate had about 86% of the activity of adenosine diphosphate as a substrate for adenosine diphosphatase of hypophysectomized rat liver membranes. The 1, N 6 -etheno derivative of nicotinamide adenine dinucleotide had about 8% of the activity of nicotinamide adenine dinucleotide as a substrate for nicotinamide adenine dinucleotide glycohydrolase and about 54% of the activity of nicotinamide adenine dinucleotide as a substrate for nicotinamide adenine dinucleotide pyrophosphatase of hypophysectomized rat liver membranes. K m 's for the ATPase, ADPase and yeast alcohol dehydrogenase using e-ATP and e-ADP and e-NAD as substrates are presented.
