Actual (reported)ZL-82 is an oral janus kinase (JAK) inhibitor. In vitro biological mass spectrometry identification test proves that ZL-82 can selectively and irreversibly inhibit JAK3. It has obvious safety advantages, with a wide therapeutic window and controllable cardiotoxicity. This is also demonstrated from preliminary GLP-conditions of acute toxicity in SD rats and Beagle dogs. Results of 4-week long-term toxicity in Beagle dogs also support this notion. Therefore, ZL-82 has the potential to treat rheumatoid arthritis. It Used to relieve and heal swelling, pain, stiffness, and limited mobility that may be caused by rheumatoid arthritis.The drug is intended to be used in patients with RA to relieve and heal swelling, pain, stiffness, and limited mobility that may be caused by rheumatoid arthritis. Pharmacodynamic studies show that ZL-82 has a strong inhibitory effect on JAK3 with IC50 of 2.8 nM, and has no obvious inhibitory effect on JAK1, JAK2 and TYK2. Compared with the similar drug Tofacitinib, its inhibitory effect on JAK3 subtype is 1nM, but its inhibition IC50 for JAK1 subtype and JAK2 subtype are 112nM and 20nM, respectively.and its selectivity is 100-fold and 20-fold, respectively.Also, the selectivity multiples of ZL-82 were 100-fold and 20-fold than tofacitinib , respectively, which indicates that ZL-82 is more selective than the marketed Tofacitinib.This allows ZL-82 to precisely inhibit JAK kinase and block a series of cytokines in the downstream signaling pathway. And show significant effect on rheumatoid arthritis. The experimental results showed that in DTH and CIA models, 25, 50, 75, and 100 mg/kg of this variety could dose-dependently inhibit joint swelling in mice. Objectives of Study Main Purpose:
