Definitions
- This invention relates to the use of CXCR4 antagonist 6- ⁇ 4-[1 -(Propan-2- yl)piperidin-4-yl]-1 ,4-diazepan-1 -yl ⁇ -N-(pyridin-4-yl)pyridine-2-carboxamide in the treatment of cancers of the breast, bladder, colon, rectum and liver.
- CXCR4 is a G-protein coupled receptor whose natural endogenous ligand is the cytokine SDF-1 (stromal derived factor-1 ; also referred to as CXCL12). CXCR4 was first discovered as a co-receptor, with CD4, for the entry of T-cell line-tropic (X4) HIV-1 into T-cells. CXCR4 manipulation (in combination with granulocyte colony stimulating factor (G-CSF)) has proven to improve the outcome of haematopoietic (Broxmeyer et al., 2005) and endothelial progenitor cell (Pitchford et al., 2009) stem cell mobilization.
- G-CSF granulocyte colony stimulating factor
- the CXCR4-SDF-1 interaction is also a master regulator of cancer stem cell trafficking in the human body (Croker and Allan, 2008) and plays a key role in the progression and metastasis of various types of cancer cells in organs that highly express SDF-1 (Zlotnik, 2008).
- CXCR4 has been shown to have a role in the formation of new blood vessels in experimental tumours (Kioi et al., 2010).
- SDF-1 is a chemokine overexpressed in many tumours which activates the CXCR4 receptor located on the surface of cancer stem cells as well as many immune cells (Kumar et al., Immunity. 2006 25(2):213-24). Activation of this receptor has been implicated in the metastatic spread of many cancers (Mukherjee et al., Am J Cancer Res. 2013; 3(1 ): 46-57), in the formation of the tumour vasculature (Kozin et al., 2010; Kioi et al., 2010), and in both the recruitment and exclusion of immune cells from tumours (Feig et al., Proc Natl Acad Sci U S A. 2013;1 10(50):20212-7).

DIPEA (14.6 mL, 83.8 mmol) and 4-aminopyridine (3.94 g, 41 .9 mmol) were added and the reaction was allowed to warm to room temperature then stirred for a further 0.5 h.
- the residue was purified by crystallisation from MeCN followed by reverse phase column chromatography.
- the residue was partitioned between DCM (300 mL) and sat aq Na 2 C0 3 solution (100 mL).
- the aqueous layer was extracted with DCM (50 mL) and the organic layers were combined, washed with brine (50 mL), dried (MgS0 4 ) and the solvents removed in vacuo.
- the residue was crystallised from MeCN to give the title compound (4.66 g, 67.3%) as a light yellow solid.
- the present invention is based at least in part on the following in vivo study.
- Study 1
- EMT-6 breast cancer
- MBT2 blade cancer
- CT26 colonal cancer
- B16F10small B16BL6
- A20 lymphoma
- LL/2 lung cancer
- Renca kidney cancer
- H22 liver cancer
- mice were treated with 6- ⁇ 4-[1 -(Propan-2-yl)piperidin-4-yl]-1 ,4-diazepan-1 - yl ⁇ -N-(pyridin-4-yl)pyridine-2-carboxamide (50mg/kg p.o. 5 days out of 7).
- Tumour growth was measured and inhibition of tumour growth reported in comparison to a vehicle treated group. All groups contained 8 mice. If the tumours in a group reached an average volume of 2000mm 3 , the experiment was terminated.
