syntheses of N1- and N2-isopropylformycin (10, 11), formycin 3',5'-cyclic and 2',3'-cyclic phosphate (3,7) and their N-methyl and N-isopropyl derivatives (13, 15, 19, 23) are described. It was observed that substitution at N1 or N2 with a bulky alkyl group or cyclic phosphorylation of the ribose moiety made formycin resistant to adenosine deaminase.
N1-和N2-异丙基甲霉素(10,11),甲酸3',5'-环和2',3'-环磷酸酯(3,7)及其N-甲基和N-异丙基衍生物的合成(13, (图15、19、23)。观察到在N1或N2处被大体积烷基取代或核糖部分的环状磷酸化使得福霉素对腺苷脱氨酶具有抗性。
