| Description | ADH-503 (GB1275) is an orally available, allosteric CD11b small molecule agonist that can lead to repolarization of tumor-associated macrophages, reduction in the number of tumor-infiltrating immunosuppressive myeloid cells, and enhancement of dendritic cell responses. |
| In vitro | METHODS: ADH-503 (GB1275) (4 μM, 10 days) was used to investigate the expression of macrophage markers in two syngeneic orthotopic models. RESULTS After treatment with ADH-503 (GB1275), macrophages expressed higher levels of MHCI, MHCII, CD80, and CD86, indicating improved antigen presentation properties of the remaining macrophages. [1] |
| In vivo | METHODS: ADH-503 (GB1275) (30, 100 mg/kg, oral) was administered to rats and C57/B6 mice to test the pharmacokinetics (PK) and safety. RESULTS The mean half-life of ADH-503 (GB1275) in rats and mice after administration was 4.68 and 3.95 hours, and the Cmax and AUC0-t in plasma were 1716 and 2594 ng/mL and 6950 and 13962 ng.h/mL, respectively.
