CAS#: 69-05-6 (HCl)

Description: Quinacrine, aslo known as Mepacrine, is A 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.

Safety Data Sheet (SDS):

Biological target: Quinacrine dihydrochloride is an antimalarial agent which suppresses NF-κB and activates p53 signaling.
In vitro activity: Quinacrine (QA) demonstrates high degree of cytotoxicity against both immortalized and primary patient-derived cell lines with sub-micromolar 50% inhibitory concentration (IC50) values ranging from 1.2 µM (H2452) to 5.03 µM (H28). Further, QA also inhibited cellular migration and colony formation in MPM (malignant pleural mesothelioma) cells, demonstrated using scratch and clonogenic assays, respectively. Anti-angiogenic properties were also discovered for QA. Autophagy inhibition assay was performed, and results revealed that QA successfully inhibited autophagy process in MPM cells, which has been cited to be one of the survival pathways for MPM. Annexin V real-time apoptosis study revealed significant apoptotic induction in MPM cells following QA treatment. Western blots confirmed inhibition of autophagy and induction of apoptosis.

In vivo activity: The efficacy of quinacrine was assessed in an AML-PS (acute myeloid leukemia) mouse model. The in vivo use of quinacrine (100mg/kg three times per week for two consecutive weeks) significantly suppressed circulating blast cells at days 30/31 and increased the median survival time (MST) of the mice. Evaluation of circulating leukemic cells detected in blood samples (in percent of white blood cells (WBC)) at day 30/31 showed 72% human tumor cells in the control mice, whereas in mice treated with quinacrine, this was only 2.2% (Fig. 1a). In agreement with these data, the MST of control mice was 34 days whereas it was 46 days in quinacrine-treated mice (p < 0.0001, Fig. 1b).
