MS1-96
MS1-96 is an orally active PD-L1 (programmed death-ligand 1) degrader. MS1-96 effectively reduced PD-L1 protein levels across multiple colorectal cancer (CRC) cell lines. MS1-96 directly binds to PD-L1 (KD = 2.58 μM) and enhances the interaction between HIP1R and PD-L1, thereby altering the intracellular trafficking of PD-L1 within clathrin-coated vesicles. MS1-96 induces abnormal N-glycosylation of PD-L1, destabilizing the protein and hastening its lysosome-mediated degradation. MS1-96 can be used for the study of colorectal cancer.

PD-L1 2.58 μM (Kd) |
MS1-96 (10 μM, 48 h) significantly reduces PD-L1 protein levels in RKO cells but shows no reduction in PD-L1 mRNA levels in RKO cells[1].
MS1-96 (0-3 μM, 0-48 h) induces PD-L1 degradation in RKO cells in a time- and dose-dependent manner[1].
MS1-96 (1.5 μM, 24 h) reduces the level of PD-L1 on the surface of RKO and LoVo cells[1].
MS1-96 (1.5 μM, 24 h) disrupts the PD-1/PD-L1 interaction by downregulating PD-L1 in RKO and LoVo cells[1].
MS1-96 (1.5 μM, 24 h) enhances the killing effect of T cells on RKO cells and reduced the number of surviving cells[1].
MS1-96 (1.5 μM, 24 h) increases LDH release in RKO cells following co-culture with activated PBMCs, indicating enhanced cytotoxicity[1].
MS1-96 (1.5 μM, 0-12 h) promotes the degradation of PD-L1 in existing RKO cells, rather than inhibiting translation, thus reducing PD-L1 levels[1].
MS1-96 (1.5 μM) degrades PD-L1 in RKO cells via the lysosomal pathway, independent of proteasomes or autophagy[1].
MS1-96 induces aberrant N-glycosylation of PD-L1 at N35, N192, N200, and N219 sites in RKO cells[1].

Animal Model:C57BL/6 mice (female, 5 weeks old) were subcutaneously inoculated with 8 × 105 MC38 colorectal cancer cells[1].
-
Dosage:0 mg/kg, 100 mg/kg, 200 mg/kg, 400 mg/kg
-
Administration:P.o., once daily for 8, 10 days
-
Result:The drug significantly inhibited the growth of MC38 tumors in a dose-dependent manner.
Tumor volume and weight were significantly reduced.
No significant change in mouse body weight indicated good drug tolerance.
Western blot analysis showed a significant decrease in PD-L1 protein levels in tumor tissues.
Depletion of CD8+ T cells alone or simultaneous depletion of CD4+ and CD8+ T cells had no anti-tumor effect.
Depletion of CD4+ T cells alone did not affect the anti-tumor effect.
