الإجراء التجريبي

A mixture of 2,6-diamino-9-(2'-O-nonyl-β-D-ribofuranosyl)purine and 2,6-diamino-9-(3'-O-nonyl-β-D-ribofuranosyl)purine (≈80:20 mixture, 29 g) in 0.1M sodium phosphate buffer (50 ml, pH 7.4), 0.1M tris buffer (1800 ml, pH 7.4) and DMSO (1080 ml) was treated with adenosine deaminase (1.6 g) as per the procedure of Example 3 to yield 60 g of product as an oil. An analytical product was purified by silica gel chromatography and recrystallized from EtOAc. m.p. 258°-259° C. 1H NMR (DMSO-d6) δ0.96 (t, 3, CH3, J=7 Hz); 1.17 [m, 12, O--CH2 --CH2 --(CH2)6 ]; 1.42 [m, 2, O--CH2CH2 (CH2)6 ]; 3.27-3.61 (m, 4, H-5', O--CH2 (CH2)7 !; 3.95 (m, 1, H-4'), 4.10-4.13 (m, 2, H-2', H-3'); 5.13-6.06 (m, 2, 3'-OH5'-OH); 5.80 (d, 1, H-1', J=6.4 Hz); 6.47 (s, 2, 2-NH2); 7.98 (s, 1, 8-H) and 10.64 (s, 1, N1 amide). Anal. Calcd. for C19H31N5O5 : C, 55.73; H, 7.63; N, 17.10. Found: C, 55.67; H, 7.66; N, 17.02.
