시험관 내(In vitro)

Baricitinib (LY3009104) inhibits IL-6–stimulated phosphorylation of the canonical substrate STAT3 (pSTAT3) and subsequent production of the chemokine MCP-1 with IC50 values of 44 nM and 40 nM, respectively, in PBMCs. This compound also inhibits pSTAT3 stimulated by IL-23 with IC50 od 20 nM in isolated naive T-cells.

키나아제 분석
Biochemical assays
Enzyme assays for Baricitinib (LY3009104) are performed using a homogeneous time-resolved fluorescence assay with recombinant epitope tagged kinase domains (JAK1, 837-1142; JAK2, 828-1132; JAK3, 718-1124; Tyk2, 873-1187) or full-length enzyme (cMET and Chk2) and peptide substrate. Each enzyme reaction is performed with or without this compound (11-point dilution), JAK, cMET, or Chk2 enzyme, 500 nM (100 nM for Chk2) peptide, ATP (at the Km specific for each kinase or 1 mM), and 2.0% DMSO in assay buffer. The calculated IC50 value is the concentration of it required for inhibition of 50% of the fluorescent signal.
생체 내(In vivo)

Baricitinib (LY3009104) inhibits IL-6–stimulated phosphorylation of STAT3 in whole blood with an IC50 of 128 nM. This compound (10 mg/kg p.o.) is expected to inhibit JAK1/2 signaling (by ≥50%) in rats for about 8 hours. It (10 mg/mL, p.o.) inhibits disease scores in dose-dependent manner in rats with established disease in the adjuvant arthritis model. This treatment, compared with vehicle, inhibits the increase in hind paw volumes during the 2 weeks of treatment by 50% at a dose of 1 mg/kg and >95% at doses of 3 mg/kg or 10 mg/kg. The compound, compared with vehicle, also inhibits composite score of immune infiltrate, edema, and periarticular tissue appearance by 27% at a dose of 1 mg/kg, 64% at doses of 3 mg/kg and 82% at doses of 10 mg/kg in rats with established disease in the adjuvant arthritis model. It reduces bone resorption by 15%, 61%, and 67% with increasing dose level (1, 3, and 10 mg/kg) in rats with established disease in the adjuvant arthritis model. This chemical (10 mg/kg, daily for 2 wk, p.o.) results in radiographic improvements with restoration of the normal architecture and appearance to the ankle and tarsals in rats with established disease in the adjuvant arthritis model. It reduces levels of pSTAT3 in a dose- and time-dependent manner in the peripheral blood of rAIA animals. This agent (10 mg/mL, p.o.) improves a composite score of joint damage by 47% in the murine CIA model. It (10 mg/kg) reduces pannus (74%) and bone damage (78%) and improves cartilage damage (43%) and signs of inflammation (33%), resulting in a 53% improvement in an aggregate score of disease in the collagen Ab-induced arthritis (CAIA) murine model. The compound (10 mg/kg) inhibits the delayed-type hypersensitivity response by 48% in both the CIA and CAIA models.

It is efficacious in active rheumatoid arthritis patients refractory to disease modifying drugs and biologics.

It preferentially inhibits JAK1 and JAK2, with 10-fold selectivity over Tyk2 and 100-fold over JAK3. The observed effects of GLPG-0634 on the ACR20, albeit in a smaller study, appear to be at least as good as that seen with tofacitinib and superior to that of baricitinib, since this chemical only moderately affect the ACR20 values in Phase IIa clinical studies.

It has the dose-limiting side-effect of inducing anaemia which has been attributed to its effects on JAK2 but has clearly shown efficacy.

자주 묻는 질문 (Frequently Asked Questions)

질문 1:
Do you know if it will dissolve directly into 0.5% methylcellulose (vehicle for oral gavage treatments) or is acid required to dissolve this compound?

답변:
It can be dissolved directly into 0.5% methylcellulose, as cited from the reference. We also tested dissolving it into 30% PEG400/0.5% Tween80/5% propylene glycol, and the solubility is about 30 mg/mL.
