Novel 7-deazapurine derivatives of the formula:
wherein X is halogen, Y is hydroxyl or di-C1-3 alkylamino, Z is a -NH- or -NHC(=NH)- group, ℓ is an integer of 1 to 5, m is an integer of 0 to 2, and n is 1 when Z is a -NH- group or n is 0 or 1 when Z is a -NHC(=NH)- group, and salts thereof are selectively taken up by tumor cells.
