Description: Bafetinib, also known as INNO-406 and NS187, is an orally bioavailable 2-phenylaminopyrimidine derivative with potential antineoplastic activity. Bafetinib specifically binds to and inhibits the Bcr/Abl fusion protein tyrosine kinase, an abnormal enzyme produced by Philadelphia chromosomal translocation associated with chronic myeloid leukemia (CML). This agent also inhibits the Src-family member Lyn tyrosine kinase, upregulated in imatinib-resistant CML cells and in a variety of solid cancer cell types.

Biological target: Bafetinib is a Lyn and Bcr-Abl tyrosine kinase inhibitor.
In vitro activity: Bafetinib (1–10 μM) concentration dependently inhibited PAR2-TRPV4 coupling. In TRPV4 HEKs, 10 μM bafetinib significantly inhibited the coupling response to SLIGRL (F340/F380 ratio 0.39 ± 0.04) and trypsin (0.52 ± 0.06) compared with vehicle control (0.66 ± 0.06 and 1.01 ± 0.11 respectively) (P < 0.05) (Figure 3). Conversely, bafetinib did not affect peak PAR2 or GSK1016790A responses (P > 0.05). Thus, bafetinib inhibits the signalling pathway leading to TRPV4 channel opening, downstream of PAR2 activation, most likely by blocking the activation of a tyrosine kinase. Reference: Br J Pharmacol. 2014 Aug;171(16):3881-94.
In vivo activity: To investigate whether tyrosine kinase activity mediates this hypersensitivity, C57BL/6 mice were treated with vehicle or bafetinib (10 mg·kg−1) by oral gavage 30 min prior to intraplantar injection of the PAR2 agonist SLIGRL into the left hind paw. von Frey mechanical pain threshold was subsequently measured at 0.5, 1, 2, 3 and 4 h after paw injection (for both the treated and non-treated paws). PAR2 activation caused marked mechanical hyperalgesia in the left paw of the vehicle-treated animals. Compared with vehicle controls, pretreatment of mice with bafetinib inhibited PAR2-induced mechanical hyperalgesia at all time points (P < 0.05) (Figure (Figure 7A). Unexpectedly, bafetinib also inhibited the GSK1016790A-mediated hyperalgesic response compared with controls (P < 0.05; Figure 6C). Reference: Br J Pharmacol. 2014 Aug;171(16):3881-94.

Additional Information

The inhibitory effect of bafetinib on these specific tyrosine kinases may decrease cellular proliferation and induce apoptosis in tumor cells that overexpress these kinases. CML patients may be refractory to imatinib, which sometimes results from point mutations occurring in the kinase domain of the Bcr/Abl fusion product. Due to its dual inhibitory activity, the use of bafetinib has been shown to overcome this particular drug resistance.
