NCIt definition : The dihydrochloride salt of the 9-aminoacridine derivative quinacrine with potential
antineoplastic and antiparasitic activities. Quinacrine may inhibit the transcription
and activity of both basal and inducible nuclear factor-kappaB (NF-kappaB), which
may result in the induction of tumor suppressor p53 transcription, the restoration
of p53-dependent apoptotic pathways, and tumor cell apoptosis. Continuous NF-kappaB
signaling, present in many tumors and in chronic inflammatory processes, promotes
the expression of antiapoptotic proteins and cytokines while downregulating the expression
of proapoptotic proteins, such as p53.;
