생물학적 활성

설명 Bemcentinib (R428, BGB324)은 Axl의 억제제로 IC50은 14 nM이며, Abl보다 Axl에 대해 100배 이상의 선택성을 나타냅니다. 또한 이 화합물은 Mer 및 Tyro3에 비해 Axl에 대해 50~100배 이상의 선택성을 가지며, InsR, EGFR, HER2 및 PDGFRβ와 비교하여 100배 더 큰 선택성을 보입니다.
표적
Axl
(Cell-free assay)
14 nM
시험관 내(In vitro) Bemcentinib (R428) blocks the catalytic and procancerous activities of Axl. It inhibits Axl with low nanomolar activity and blocks Axl-dependent events, including Akt phosphorylation, breast cancer cell invasion, and proinflammatory cytokine production. In a recent study, this compound shows a mean IC50 dose of ∼ 2.0μM for the primary CLL B cells after 24 hours of treatment and normal B-, T-, and natural killer (NK) cells show no significant amount of cell death at this dose of R428 (2.5 μM) under similar experimental conditions.
생체 내(In Vivo) Pharmacologic investigations reveal favorable exposure after oral administration of Bemcentinib (R428), such that treated tumors display a dose-dependent reduction in expression of the cytokine granulocyte macrophage colony-stimulating factor and the epithelial-mesenchymal transition transcriptional regulator Snail. In support of an earlier study, it inhibits angiogenesis in corneal micropocket and tumor models. This compound also reduces metastatic burden and extends survival in MDA-MB-231 intracardiac and 4T1 orthotopic (median survival, >80 days compared with 52 days; P < 0.05) mouse models of breast cancer metastasis.

고객 제품 검증

Cetuximab-resistant cells are sensitive to therapeutic blockade of AXL activity with the AXL TKI R428. Cells were treated with vehicle (-) or indicated doses of R428 for 24 hours before harvesting whole-cell lysate and immunoblotting for the indicated proteins. α-Tubulin was used as a loading control.

Axl inhibitor promotes the apoptosis induced by ALK-TKIs. (A) After treated with crizotinib (100 nM), BGB324 (300 nM) or their combination for 48 h, cell apoptosis was determined by flow cytometry. (B) The induction of apoptosis by ceritinib (100 nM), BGB324 (300 nM) or their combination was examined. (C and D) Cells were treated with crizotinib (100 nM), BGB324 (300 nM) or their combination for 48 h, then whole-cell lysates were collected and the levels of indicated protein were analyzed by Western blot in (C) NB1643 and (D) SHSY5Y cells. *P < 0.05 for the indicated comparisons; ns, not significant.

<p>B) The processing of AXL is increased by an AXL kinase inhibitor. Panc-28 cells were incubated overnight with DMSO or 150 nM R428, a selective AXL kinase inhibitor, before examining by Western blot the levels of endogenous AXL-FL and AXL-CTF (C-20; left). Levels of AXL-CTF in DAPT-treated cells were quantified as described above and unpaired Student’s t test was employed for the analysis (right). Data are shown as means±SEM (n = 4). ***P<0.001.</p>
