(D)-PPA 1 is a hydrolysisresistant d-peptide antagonist. (D)-PPA 1 serves as a potent PD-1/PD-L1 inhibitor. (D)-PPA 1 binds to PD-1 with the affinity 0f 0.51 μM with in vitro and in vivo efficacy[1]. | [in vivo]
(D)-PPA 1 (2 mg/kg; s.c. or i.p.; once daily for 7 d) inhibits CT26 tumor growth in vivo in mice[1].
(D)-PPA 1 (40 μg/mouse in 200 μL; i.v.; single dose) has the ability to target to tumor tissue in CT26-tumor-bearing mice[1].
| Animal Model: | CT26-tumor-bearing Balb/c mice[1] | | Dosage: | 2 mg/kg | | Administration: | 1) Subcutaneous injection, for around the tumor once every day for 7 days
2) Intraperitoneal injection, once every day for 7 days
3) Intraperitoneal injection, once every day for 12 days; recorded the survival on day 13 | | Result: | Inhibited tumor growth, and prolonged the survival in mice. |
