Heterosubstituted anthracene-9,10-dione analogs. The synthesis and antitumor evaluation of 5,8-bis[(aminoalkyl)amino]naphtho[2,3-b]thiophene-4,9-diones

Abstract
A number of 5,8-bis[(aminoalkyl)amino]naphtho[2,3-b]thiophene-4,9-diones have been synthesized and evaluated for antitumor activity against L1210 leukemia both in vitro and in vivo. Two of the congeners exhibited in vivo activities quite comparable to that of mitoxantrone.
