Isothiazolopyrimidines--new group of anticancer agents. II.

In reactions of 5-aminoisothiazolopyrimidines 1 with glycosilisothiocyanates and phenyl isocyano- or isocyanates, N-glycosilo-N-phenylo- and N-isothiazolopyrimidinothiocarbamides type II were obtained. The same compound--5-aminoisothiazolopyrimidine 1 in reaction with glucose, arabinose and ribose bromoderivatives was converted into N-glycosiloaminoisothiazolopyrimidies type 3. Some of the newly synthetized compounds appeared effective against L-1210 leukemia and Sa-180 sarcoma.
