(3s,4s)tofacitinib

(3S,4S)-Tofacitinib, a less active enantiomer of tofacitinib, is a Janus kinases inhibitor.

Tofacitinib (Tasocitinib) 是一种 Janus 激酶抑制剂，抑制 JAK3/2/1 (IC50=1/20/112 nM)，具有口服活性。Tofacitinib 被用于治疗中度至重度类风湿性关节炎。

(3R,4S)-Tofacitinib is an less active enantiomer of Tofacitinib. Tofacitinib is a JAK3 inhibitor(IC50 : 1 nM).

(3S,4R)-Tofacitinib is an less active enantiomer of Tofacitinib. Tofacitinib is a JAK3 inhibitor(IC50 : 1 nM).

Tofacitinib Citrate (CP-690550 citrate) 是 JAK1/2/3抑制剂，IC50分别为112，20 和 1 nM。它具有抗菌，抗真菌和抗病毒活性。

Tofacitinib HCl, also known as tasocitinib, CP-690550, is a Janus kinase (JAK) inhibitor. Tofacitinib HCl modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through pairing of JAKs (e.g., JAK1/JAK3, JAK1/JAK2, JAK1/TyK2, JAK2/JAK2). Tofacitinib HCl inhibited the in vitro activities of JAK1/JAK2, JAK1/JAK3, and JAK2/JAK2 combinations with IC50 of 406, 56, and 1377 nM, respectively.

Tofacitinib maleate, also known as tasocitinib, CP-690550, is a Janus kinase (JAK) inhibitor. Tofacitinib maleate modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through pairing of JAKs (e.g., JAK1/JAK3, JAK1/JAK2, JAK1/TyK2, JAK2/JAK2). Tofacitinib maleate inhibited the in vitro activities of JAK1/JAK2, JAK1/JAK3, and JAK2/JAK2 combinations with IC50 of 406, 56, and 1377 nM, respectively.
