    • 7-Deazapurine derivatives of the formula: ##STR1## wherein R.sup.1 is phenyl which has, at the ortho position and/or para position as substituents, at least one group represented by the formula --O--R.sup.3, --S--R.sup.4 or ##STR2## (wherein R.sup.3, R.sup.4, R.sup.5 and R.sup.6 are the same or different and each is hydrogen or an alkyl or phenyl group which may be substituted, whereby R.sup.5 and R.sup.6, together with the adjacent nitrogen atom, may form a cyclic amino group which may be substituted, and R.sup.3, R.sup.4, R.sup.5 and R.sup.6 each may represent a protective group), and may have a group or groups with a molecular weight of up to about 200 as a substituent at any position other than those having the said substituents introduced; R.sup.2 is an amino group which may be protected, or its salt, have a potent antitumor activity, and hence the compounds are useful as an antitumor agent.
    • 其中R 1是在取代基的邻位和/或对位具有至少一个由式-O-R 3,-S-R 4或(其中R 3,R 4,R 5和R 6相同或不同,各自为氢或可被取代的烷基或苯基,其中R 5和R 6与相邻的氮原子一起可形成环状氨基, 并且R 3,R 4,R 5和R 6各自可以表示保护基),并且可以具有除了引入了所述取代基的那些以外的任何位置具有至多约200的分子量的基团作为取代基的基团; R2是可被保护的氨基或其盐具有有效的抗肿瘤活性,因此该化合物可用作抗肿瘤剂。
