Abstract

Novel analogues of P1,P4-bis(5'-adenosyl) tetraphosphate, Ap4A (1), have been prepared with sulphur substituents at P1 and P4 and either oxygen or methylene bridges at the P2,P3-position. Separation of three isomers of the ApspCH2ppsA species has been achieved by a combination of mplc and hplc and the Rp,Rp, Rp,Sp, and Sp,Sp diastereoisomers identified on the basis of selective enzymatic hydrolysis using snake venom phosphodiesterase. Each of these three isomers is a strong competitive inhibitor of the specific Ap4Aase from Artemia and is highly resistant to the asymmetric cleavage normally catalysed by this enzyme.
