Photolysis of 2-dialkylamino-3-amino(or alkylamino)-1,4-naphthoquinones
摘要:
Using H-1 and C-13 NMR spectroscopy, naphthodihydroimidazolediols were identified as the primary products of photolysis of 2-dialkylamino-3-amino(alkylamino)-1,4-naphthoquinones. Their further non-photochemical (<>) transformations depend on their structure and on the photolysis conditions.
Provided herein are compounds of the formula (IV):
as well as pharmaceutically acceptable salts thereof, wherein the substituents are as those disclosed in the specification. These compounds, and the pharmaceutical compositions containing them, are useful as MITF inhibitors, MITF pathway inhibitors and for the treatment of cancer.
