Ingemuva

I-Tofacitinib citrate, eyaziwa nangokuthi i-CP-690550 citrate, iyi-inhibitor enamandla ye-janus kinase 3 (JAK3), i-tyrosine kinase ekhawulelwe ngamaseli e-hematopoetic ehilelekile ekudlulisweni kwesignali elawula ukusinda kwe-lymphocyte, ukwanda, ukuhlukaniswa, kanye ne-apoptosis.Ukuvinjelwa kucaciswe nge-JAK3 ngokukhetha okuphindwe ka-1000 ngaphezu kwamanye ama-kinase omndeni angewona ama-JAK.Ngaphandle kokuvimbela i-JAKS (IC50 = 1 nM), i-tofacitinib citrate iphinde ivimbele i-janus kinase 2 (JAK2) kanye ne-janus kinase 1 (JAK1) enamandla angu-20- kanye ne-100 ngokulandelana.Nokho, ocwaningweni lwakamuva, izibopho ezibophezelayo (Ki) ze-tofacitinib citrate eziya ku-JAK1, JAK2, ne-JAK3 kubikwe ukuthi ziyi-1.6 nM, 21.7 nM, kanye ne-6.5 nM ngokulandelanayo.
