Hydrolysis of phosphatidylnucleosides, 5'-(rac-1-hexadecyl-2-palmitoyl-sn-g
lycero-3-phosphoryl)-3'-azido-3'-deoxythymidine and -2',3'-didehydro-3'-deo
xythymidine, effected by phospholipases (PL) A(2), C, and D was studied to
reveal the metabolism of these derivatives. It was shown that PLA(2) deacet
ylates the glycerol residue at position 2. PLC is inactive, anti PLD hydrol
yzes the phosphatidylnucleosides to give free nucleosides.
