✦ Synopsis


boulevard d'Yvoy, 1205 Gcnbve (17 Xi 71) Smnwzary. The title compound, a n apionucleoside, has been synthesized and is shown by S M R . t o exist mainly in the conformation E3,. The reasons why this branched-chain nucleoside is not a substrate for-adenosine cleaminase are discussed. The compound inhibits the growth of Escherichia coli and Staphylococcus a w e u s in synthetic liquid media. Depuis la synthkse par Walton et coll. [Z] en 1966 du premier nuclkoside a sucre ramifik, un certain nombre d'exemples de ce type d'analogues de nuclkosides naturels ont ktk prkparks [3] (41 [5] et l'activitk antivirale ou anticandreuse de quelques-uns d'entre eux a Btk dkmontrke 141. L'intCr&t biologique de ces composks provient de leur analogie structurale avec les nucl6osides naturels et l'on peut, a p ~i o r i , penser que plus ktroite sera cette analogie, plus intkressants seront les composks prkparks.
