Parsaclisib (INCB050465) 是一种有效，选择性和具有口服活性的PI3Kδ抑制剂，IC50值为 1 nM。Parsaclisib 相对于其他 PI3K I 类同工型的选择性约为 20000 倍。Parsaclisib 可用于研究复发或难治性 B 细胞恶性肿瘤。
| 生物活性 | Parsaclisib (INCB050465) is a potent, selective and orally active inhibitor ofPI3Kδ, with anIC50of 1 nM at 1 mM ATP. Parsaclisib shows approximately 20000-fold selectivity over otherPI3Kclass I isoforms. Parsaclisib can be used for the research of relapsed or refractory B-cell malignancies[1][2][3]. |

体外研究
(In Vitro) | Parsaclisib (0.1-3000 nM; 4 d) inhibits proliferation of MCL and DLBCL cell lines[2].
Parsaclisib (0.1-1000 nM; 2 h) inhibits anti-IgM-induced pAKT (Ser473) in the Ramos Burkitt’s lymphoma cell line, with an IC50of 1 nM[2].
Parsaclisib inhibits the proliferation of human, dog, rat, and mouse primary B cells after activation of these receptors, with IC50s ranging from 0.2 to 1.7 nM[2].
Cell Proliferation Assay[2] | Cell Line: | Jeko-1, Mino, JVM2, Rec-1, Pfeiffer, SU-DHL-5, SU-DHL-6, WSU-NHL, SU-DHL-4, SU-DHL-8, and WILL-2 cells | | Concentration: | 0.1-3000 nM | | Incubation Time: | 4 days | | Result: | Resulted in a maximal inhibition of 70-90%, with IC50s of ≤10 nM in the four MCL cell lines.
Pfeiffer, SU-DHL-5, SU-DHL-6, and WSU-NHL were highly sensitive, with IC50s from 2 to 8 nM. |

体内研究
(In Vivo) | Parsaclisib (10 mg/kg; oral gavage twice daily for 7-19 days) inhibits tumor growth in the BALB/c mice bearing the A20 murine lymphoma cells[2].
Parsaclisib (0.1-10 mg/kg; p.o. twice daily) slows Pfeiffer xenograft tumor growth in a dose-dependent manner. And Parsaclisib was well tolerated[2].
Parsaclisib (0.5-1 mg/kg; a single p.o.) inhibits pAKT (Ser473) in Pfeiffer subcutaneous mouse xenograft models[2].
| Animal Model: | Female BALB/c mice (5-9 weeks) were inoculated with A20 cells[2] | | Dosage: | 10 mg/kg | | Administration: | Oral gavage twice daily for 7-19 days | | Result: | Resulted in significant tumor growth inhibition (TGI).
Reduced the percentage of Tregs (CD4+CD25+FOXP3+) in tumors and spleens.
Increased the ratio of CD4+and CD8+T cells to Tregs in spleens and tumors.
Decreased the number of CD4+CD44highand CD8+CD44highT cells in both spleens and tumors. |
