Summary
WRG-28 is a selective, extracellularly acting DDR2 allosteric inhibitor, with an IC 50 of 230 nM. WRG-28 inhibits tumor invasion, migration and tumor-supporting effects of cancer-associated fibroblasts (CAFs). WRG-28 inhibits metastatic breast tumor cell colonization in the lungs. WRG-28 also shows good activity of relieving rheumatoid arthritis in CAIA model of mice [1] [2] .
IC50 & Target
|
DDR2 230 nM (IC 50 ) |
In Vitro
WRG-28 (1, 2 µM; 4 h) blunts collagen I-mediated DDR2 tyrosine phosphorylation and (1 µM; 7 h) ERK activation as well as SNAIL1 protein stabilization in HEK293 cells (expressing DDR2) (IC
50
=286 nM)
[1]
.
WRG-28 (1 μM; 48 h) blunts tumor cell invasion and migration by inhibiting DDR2 in BT549 and 4T1 breast cancer cells
[1]
.
WRG-28 (1 μM; 4 days) inhibits tumor-promoting effects of CAFs
[1]
.
WRG-28 (0.5, 1 μM; 4 h) maintains inhibitory action toward acquired DDR2 mutations that are resistant to TKIs
[1]
.
MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Viability Assay [1]
| Cell Line: | HEK293 cells (transfected with DDR2-Flag) |
| Concentration: | 0.25, 0.5, 1, 2 µM |

| Result: | Significantly inhibited collagen I-mediated DDR2 tyrosine phosphorylation at 1 or 2µM, and with an IC>sub>50 of 286 nM. |
Cell Viability Assay [1]
| Cell Line: | HEK293 cells (transfected with DDR2-Flag) |
| Concentration: | 1 µM |
| Incubation Time: | 7 h |
| Result: | Inhibited collagen I-mediated ERK activation and SNAIL1 protein stabilization (IC 50 =286 nM). |
Cell Viability Assay [1]
| Cell Line: | BT549 and 4T1 breast cancer cells (expressing endogenous DDR2) |
| Concentration: | 1 μM |
| Incubation Time: | 48 h |
| Result: | Inhibited DDR2 induced invasion and migration of tumor cells. |
Cell Viability Assay [1]
| Cell Line: | CAF cells (with tumor organoids) |
| Concentration: | 1 μM |
| Incubation Time: | 4 days |
| Result: | Inhibited the activity of DDR2 that supported invasion of primary tumor organoids in CAFs. |
Cell Viability Assay [1]
| Cell Line: | HEK293 cells (expressing DDR2 T654I ) |
| Concentration: | 0.5, 1 μM |
| Incubation Time: | 4 h |

| Animal Model: | Female BALB/cJ mice (8-week-old; 4T1-Snail-CBG tumor-bearing mice model) [1] . |
| Dosage: | 10 mg/kg |
| Administration: | Intravenous injection, single. |
| Result: | Reduced 60% SNAIL1-clic beetle green (SNAIL1.CBG) level within the tumor in mice. |
| Animal Model: | Female BALB/cJ mice (8-week-old; injected with 4T1 GFP-luc expressing cells) [1] . |
| Dosage: | 10 mg/kg |
| Administration: | Intravenous injection, single daily for 7 days. |
| Result: | Reduced lung colonization to a level comparable to shDDR2-depleted cells. |
| Animal Model: | Male DBA/1 mice (8-week-old; CAIA model) [2] . |
| Dosage: | 10 mg/kg |
| Administration: | Intravenous injection, single daily for 21 days. |
| Result: |
Significantly ameliorated arthritis in the mice (reduced production of IL-15 and Dkk-1), the hind- paw thickness of the mice was also reduced.
Inhibited inflammatory cell infiltration and destruction of cartilage in mouse ankle and serum. Significantly alleviated bone destruction, reduced the extent of joint space enlargement and bone mineral density, as well as decreased the severity of bone loss. |
