Reversal of the regioselectivity of anthrapyrazole formation. A new synthesis of Losoxantrone (DUP941)

Losoxantrone, a potent anticancer agent, has been efficiently synthesized in a 6 step process from 5-hydroxy-1,4- dichloroanthracene-9,10-dione.

Anticancer anthrapyrazoles. Improved syntheses of clinical agents CI-937, CI-941, and piroxantrone hydrochloride

Improved processes for the synthesis of bulk quantities of the anthrapyrazole clinical agents CI-937, CI-941, and piroxantrone hydrochloride are reported. Reported also are detailed analytical and spectroscopic data for these agents and intermediates of t

Process for preparing substituted anthra[1,9-cd]pyrazol-6(2H)-ones

An improved process for producing anthra[1,9-cd]-pyrazol-6(2H)-ones from 1,4-dichloro-5,8-disubstituted 9,10-anthracenediones. The process produces higher yields by using a new combination of protecting groups on the compounds which allows for easier and cleaner chromatographic resolution. The compounds produced have antibacterial, antifungal, antileukemic, and antitumor activity.
