Synthesis and Anti-Proliferative Activity of Sulfanyltriazolylnaphthalenols and Sulfanyltriazolylnaphthalene-1,4-diones

A series of new sulfanyltriazolylnaphthalenols (10a–f and 13a–f) and sulfanyltriazolylnaphthalene-1,4-diones (14a–f) were synthesized and evaluated against a panel of cancer cell lines. Among the tested compounds, 10b and 10d showed the best anti-proliferative activity with GI values ranging from 2.72 to 10 and 3.13 to 13.1 µM, respectively, in several of the tumor cell lines tested. Compound 10d is highly selective toward leukemia cell lines and can be regarded as a good model for the development of new anti-leukemic agents.
