General Description

5-bromo-3-((trimethylsilyl)ethynyl)pyrazin-2-amine is a chemical compound with the molecular formula C9H11BrN4Si. It is a brominated pyrazine derivative that is commonly used in the synthesis of pharmaceuticals and organic compounds. The presence of bromine and trimethylsilyl ethynyl groups in the molecule makes it a valuable building block for the construction of various biologically active compounds. 5-bromo-3-((trimethylsilyl)ethynyl)pyrazin-2-amine is often employed in medicinal chemistry research and drug discovery programs due to its synthetic versatility and potential pharmacological properties. Additionally, the trimethylsilyl group in the molecule provides steric hindrance, which can affect its reactivity and influence its interactions with other chemical compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 875781-41-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,5,7,8 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 875781-41:
(8*8)+(7*7)+(6*5)+(5*7)+(4*8)+(3*1)+(2*4)+(1*1)=222
222 % 10 = 2
So 875781-41-2 is a valid CAS Registry Number.

Development of a Scalable Enantioselective Synthesis of JAK Inhibitor Upadacitinib

Rozema, Michael J.,Bhagavatula, Lakshmi,Christesen, Alan,Dunn, Travis B.,Ickes, Andrew,Kotecki, Brian J.,Marek, James C.,Moschetta, Eric,Morrill, Westin H.,Mulhern, Mathew,Rasmussen, Michael,Reynolds, Troy,Yu, Su

, p. 949 - 962 (2021/10/21)

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.

Discovery and Toxicological Profiling of Aminopyridines as Orally Bioavailable Selective Inhibitors of PI3-Kinase γ

Bellenie, Benjamin R.,Hall, Edward,Bruce, Ian,Spendiff, Matthew,Culshaw, Andrew,McDonald, Sarah,Ambarkhane, Ameet,Chinn, Colin,Thomas, Matthew,Rosner, Elisabeth,Bracher, Marguerite,Nicklin, Paul,Marshall, Stephen,Coote, Julie,Cullen, Eva,Tessier, Clemence,Wuersch, Kuno,Lal, Ajay,Wallis, Gillian,Hollingworth, Gregory J.,Neef, James

, p. 12304 - 12321 (2021/09/02)

Using a novel physiologically relevant in vitro human whole blood neutrophil shape change assay, an aminopyrazine series of selective PI3Kγinhibitors was identified and prioritized for further optimization. Severe solubility limitations associated with the series leading to low oral bioavailability and poor exposures, especially at higher doses, were overcome by moving to an aminopyridine core. Compound 33, with the optimal balance of on-target activity, selectivity, and pharmacokinetic parameters, progressed into in vivo studies and demonstrated good efficacy (10 mg/kg) in a rat model of airway inflammation. Sufficient exposures were achieved at high doses to support toxicological studies, where unexpected inflammatory cell infiltrates in cardiovascular tissue prevented further compound development.
