CA-170 is an orally bioavailable dual inhibitor of VISTA and PD-L1 that selectively restores T-cell proliferation and effector function suppressed by immune checkpoint signaling, while demonstrating minimal off-target activity across a broad receptor and enzyme panel, making CA-170 a valuable compound for immuno-oncology research and immune checkpoint modulation studies.

| Description | CA-170 is an orally bioavailable dual inhibitor of VISTA and PD-L1 that selectively restores T-cell proliferation and effector function suppressed by immune checkpoint signaling, while demonstrating minimal off-target activity across a broad receptor and enzyme panel, making CA-170 a valuable compound for immuno-oncology research and immune checkpoint modulation studies. |
| In vitro | PD-1 is a co-receptor that is expressed predominantly by T cells. The binding of PD-1 to its ligands, PD-L1 or PD-L2, is important for the physiological regulation of the immune system[1]. |
| In vivo | In preclinical studies using syngeneic mouse tumor models (e.g., colorectal cancer and melanoma), oral administration of CA-170 inhibits tumor growth [1]. |

DMSO
| |||||||||||||||||||||||||||||||
Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
