Peficitinib hydrobromide is used in the treatment of Psoriasis and Rheumatoid Arthritis

Peficitinib (formerly known as ASP015K) is a pyrrolo[2,3-b]pyridine derivative orally administered once-daily JAK inhibitor in development for the treatment of Rheumatoid Arthritis. In preclinical studied Peficitinib inhibited JAK1 and JAK3 with IC50 of 3.9 and 0.7 nM, respectively. Peficitinib also inhibited IL-2-dependent T cell proliferation in vitro and STAT5 phosphorylation in vitro and ex vivo. Furthermore, Peficitinib dose-dependently suppressed bone destruction and paw swelling in an adjuvant-induced arthritis model in rats via prophylactic or therapeutic oral dosing regimens.In clinical trials, Peficitinib treatment prescribed at 50, 100 and 150 mg amounts each showed statistically significantly higher ACR20 response rates compared to the placebo and response…

ntibiotics are the most effective drugs for curing bacteria-infectious diseases clinically. They have a wide market due to their advantages of good antibacterial effect with limited side effects. Among them, the beta-lactam class of antibiotics (for example, penicillins, cephalosporins, and carbapenems) is widely used because they have a strong bactericidal effect and low toxicity.

[0005] To counter the efficacy of the various beta-lactams, bacteria have evolved to produce variants of beta-lactam deactivating enzymes called beta-lactamases, and in the ability to share this tool inter- and intra-species. These beta-lactamases are categorized as“serine” or“metallo” based, respectively, on presence of a key serine or zinc in the enzyme active site. The rapid…
