1310726-60-3 Usage
Introduction
Upadacitinib (ABT-494) is a Janus kinase 1 (JAK1) inhibitor currently being developed by AbbVie for the treatment of rheumatoid arthritis (RA), Crohn’s disease, ulcerative colitis, atopic dermatitis, and psoriatic arthritis. It is also being investigated as a potential treatment for people with active ankylosing spondylitis (AS).
AS is an inflammatory, progressive autoimmune disease that affects the joints of the spine. As the disease progresses, calcium deposits form where ligaments attach to the bones that form the spine, leading to reduced flexibility of the back.
use
Upadacitinib is a potent and selective Janus kinase (JAK) 1 inhibitor with an IC50 of 43 nM.Upadacitinib is a JAK1 selective inhibitor being investigated to treat rheumatoid arthritis, Crohn's disease, ulcerative colitis, atopic dermatitis, psoriatic arthritis, axial SpA and Giant Cell Arteritis and Takayasu Arteritis.
Description
Different sources of media describe the Description of 1310726-60-3 differently. You can refer to the following data:
1. Upadacitinib is a JAK1 inhibitor (IC50 = 47 nM). It is selective for JAK1 over JAK3 and tyrosine kinase 2 (Tyk2; IC50s = 2,304 and 4,690 nM, respectively), as well as a panel of 83 additional kinases at 1 μM, but does inhibit JAK2, Rho-associated kinase I (ROCK1), and ROCK2 (IC50s = 120, 920, and 430 nM, respectively). Upadacitinib decreases cytokine-induced STAT phosphorylation in a variety of human cells with IC50 values ranging from 1.6 to 649 nM. It reduces M. tuberculosis-induced paw swelling and bone erosion in a rat model of arthritis when administered at doses of 1, 3, and 10 mg/kg twice per day for 17 days. Formulations containing upadacitinib have been used in the treatment of rheumatoid arthritis.
2. Upadacitinib (ABT-494) is a JAK1 selective inhibitor being investigated to treat rheumatoid arthritis, Crohn's disease, ulcerative colitis, atopic dermatitis, psoriatic arthritis, axial SpA Giant Cell Arteritis and Takayasu Arteritis.
Uses
Upadacitinib also known as ABT-494, is a potent and selective Janus kinase (JAK) 1 inhibitor being developed for the treatment of several autoimmune disorders, Janus kinase inhibitors for rheumatoid arthritis.
Mechanism of action
The Janus kinases (JAKs) are a family of cytoplasmic tyrosine kinases whose function is to transduce cytokine-mediated signals via the JAK-STAT pathway. There are four JAK subtypes, each of which has overlapping receptor responsibilities. Inhibitors of this enzyme family (jakinibs) have shown efficacy in treating certain inflammatory and autoimmune diseases such as rheumatoid arthritis and Crohn's disease. However, the first generation of these drugs, tofacitinib and ruxolitinib, lacked subtype selectivity, affecting JAK1/JAK3 and JAK1/JAK2 respectively. This has led to dose-limiting side effects in this otherwise promising class of drugs. Upadacitinib is a second generation Janus kinase inhibitor that is selective for the JAK1 subtype of this enzyme over the JAK2 (74-fold), JAK3 (58-fold) and tyrosine kinase 2 subtypes.
Clinical Use
Upadacitinib is indicated for the treatment of moderate to severe active rheumatoid arthritis in adults who have responded inadequately to, or who are intolerant to one or more disease-modifying antirheumatic drugs (DMARDs). Upadacitinib may be used as monotherapy or in combination with methotrexate.
Side effects
Common side effects are upper respiratory tract infections such as common cold and sinus infections (13.5% of patients in studies), nausea (3.5%), cough (2.2%), fever, and increased liver enzymes. Serious side effects include infections, including life-threatening ones, such as pneumonia, cellulitis, tuberculosis, as well as shingles and other herpes infections.
Synthesis
To a solution of (3S,4R)-3-ethyl-4-(3-tosyl-3H-imidazo[l,2-a]pyrrolo[2,3-e]pyrazin-8-yl)- N-(2,2,2-trifluoroethyl)pyrrolidine-l-carboxamide (10 g) in tetrahydrofurane (50 ml_), a 10% solution of sodium hydroxide in water (15 ml) was added and heated to 50°C. The reaction mixture was stirred for 5 hours and cooled to 25°C. A saturated solution of sodium chloride (100 ml_) was added to the reaction mixture and extracted with dichloromethane (100 ml). The organic phase was separated and washed with water (100 ml_). An 2.5 % aqueous solution of HCI (100 ml) was added and stirred for 30 minutes. The organic phase was removed and the resultant acid aqueous phase was extracted with dichloromethane (100 ml). The final aqueous phase was cooled down to 0/5 °C and a 10% solution of NaOH was charged until pH 10/12. The resultant suspension was filtered and washed with water (2 x 50 ml_). The cake was drained and dried at 30/40°C under vacuum to give an almost white amorphous solid. Yield: 80%. 1 H NMR (400MHz, d-DMSO) 612.27 (s,1H), 8.58 (s,1H), 7.47-7.43 (m,2H), 7.00-6.94 (m,2H), 4.38 -4.33 (m,1H), 3.92-3.67 (m,5H), 3.33-3.25 (m,1 H), 2.59-2.54 (m,1 H), 1.14-1.08 (m,1 H), 0.86-0.78 (m, 1H), 0.65-0.62 (m, 3H).
Check Digit Verification of cas no
The CAS Registry Mumber 1310726-60-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,0,7,2 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1310726-60:
(9*1)+(8*3)+(7*1)+(6*0)+(5*7)+(4*2)+(3*6)+(2*6)+(1*0)=113
113 % 10 = 3
So 1310726-60-3 is a valid CAS Registry Number.

Process development of a six-stage synthesis of upadacitinib, a JAK1 inhibitor, is described. It is highlighted by an enantioselective and diastereoselective hydrogenation of a tetrasubstituted olefin to set the two pyrrolidine stereocenters. Preparation of the main fragments and strategies to link them together, optimization of the imidazole cyclization, and in-depth understanding of the formation of the urea moiety at the final stage are discussed.

The synthesis method takes compound 1 as a starting raw material, is subjected to chlorination, coupling, hydrolysis and hydrogenation into a salt to obtain compound 4, and then derivatized with erucic acid and halogenated to obtain the intermediate compound 6. Next, we utilize 2 - bromo -5 - p tosyl - 555H-pyrrolo [2, 3 - b] pyrazine compound 7 as starting materials for aminolysis and amino protection to obtain the intermediate compound 9. Of Compound 6 and Compound 9 A Chemical Formula 10 was obtained, and then a key mother nucleus 11 was obtained by using trifluoroacetic anhydride to form a ring. Finally, the butt reaction of triethylamine is optimized, and the product is obtained by two methods.
