SCL-1 is an orally active anti-PD-1/PD-L1 inhibitor that disrupts the interaction between PD-1 and PD-L1. It enhances the numbers of T cells, B cells, and natural killer cells. SCL-1 exhibits potent tumor growth inhibitory effects by inducing effector T cells within the tumor and upregulating the expression of long non-coding RNAs as neoantigens, thereby activating cytotoxic T lymphocytes. SCL-1 is applicable in cancer research, including studies on triple-negative breast cancer.

| In vitro | SCL-1 (0.25-100 μM, 4 days) does not exhibit significant cytotoxicity to MDA-MB231 cells. At a concentration of 25 μM, SCL-1 shows moderate inhibitory activity for PD-1/PD-L1 binding, with an inhibition rate of 63%. Additionally, SCL-1 inhibits the proliferation of SCC3 and Jurkat cells, with IC 50 values both greater than 50 μM. |
| In vivo | SCL-1, administered orally at doses of 25-100 mg/kg, ten times over 14 days, inhibits tumor growth in MHC-dKO NOG mice with humanized MDA-MB231 tumor load. Similarly, SCL-1 at a dose of 50 mg/kg, given orally under the same schedule, reduces tumor growth in MHC-dKO NOG mice with humanized SCC-3 tumor load. |
