RPT193 is an orally active inhibitor of CCR4, blocks the recruitment of Th2 inflammatory immune cells into inflamed tissues. RPT193 can be used for allergic inflammation in atopic dermatitis, asthma, and other diseases research[1].
RPT193 (1 nM-10 μM) inhibits Th2 cells chemotaxis or migration with IC50s of ~370 nM[2].
RPT193 (100 mg/kg; p.o.; once daily; 2 d, 1 d before OVA-challenge) reduces skin inflammation in an acute ovalbumin (OVA)-induced atopic dermatitis model in mice[2].
Animal Model: | Acute ovalbumin (OVA)-induced atopic dermatitis model in mouse[2] |
Dosage: | 100 mg/kg |
Administration: | Oral gavage; once daily; for 2 days, started 1 day before OVA-challenge (in mouse ear) |
Result: | Decreased the ear thickness significantly. |

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
