问题 1:
I was just wondering what the main differences between S2789 and S5001?
回答：
S2789(Tofacitinib (CP-690550)) is the base form of S5001 (Tofacitinib (CP-690550) Citrate). The biological activity of these two compounds are same. The S5001 (Tofacitinib (CP-690550) Citrate) is more suitable for oral administration.
