N-(Polysaccharidyl) nitrogen-containing heterocyclic compounds, especially based on pyrimidine or purine.Some chemicals with cas registry numbers like 10457-14-4 and 18037-10-0 are also used. Vorbrueggen, Helmut; Niedballa, Ulrich (Schering A.-G., Ger.). Ger. Offen. DE 2514275 14 Oct 1976, 39 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C07H019-02. APPLICATION: DE 75-2514275 27 Mar 1975. DOCUMENT TYPE: Patent CA Section: 33 (Carbohydrates) Section cross-reference(s): 9, 80 Purine and pyrimidine bases were bound to cellulose derivs. for use in the affinity chromatog. sepn. of nucleosides. Thus, triacetylcellulose was treated with HOAc-Ac2O and the partially cleaved cellulose treated with O,N-bis(trimethylsilyl)cytosine to give I (n = 34, R = 1-cytosyl). I (R = 1-cytosyl, n = 43, 35, 36, 27, 100, 10; R = 1-uridyl, n = 35, 98, 10; R = 6-N-benzoyl-9-adenyl, n = 31; R = 6-N-(3-methyl-2-butenyl)-9-adenyl, n = 32; R = 6-N-octanoyl-9-adenyl, n = 97, 10; R = 9-adenyl, n = 30, 97, 10) were similarily prepd. Cytosine derivs. were also prepd. from starch triacetate and acetylated agarose. Guanosine was quant. retained from a mixt. with cytidine on I (R = 1-cytosyl, n = 34) and was eluted with Tris buffer-0.1N NaCl. .
