251549-38-9 Usage

General Description

Pyrazinamide, 5-(methylthio)- (9CI), is a chemical compound that is used as an antibiotic to treat tuberculosis. It works by inhibiting the growth of the bacteria that cause the disease. It is often used in combination with other antibiotics to effectively treat tuberculosis infections. Pyrazinamide is considered an essential component of the first-line treatment for tuberculosis and is included in the World Health Organization's list of essential medicines. It is typically administered orally and is generally well tolerated, with common side effects including digestive upset and liver toxicity. Despite these potential side effects, pyrazinamide is widely used and considered a crucial tool in the treatment of tuberculosis.

Check Digit Verification of cas no

The CAS Registry Mumber 251549-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,5,4 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 251549-38:
(8*2)+(7*5)+(6*1)+(5*5)+(4*4)+(3*9)+(2*3)+(1*8)=139
139 % 10 = 9
So 251549-38-9 is a valid CAS Registry Number.

BF3·SMe2 for Thiomethylation, Nitro Reduction and Tandem Reduction/SMe Insertion of Nitrogen Heterocycles

S?derstr?m, Marcus,Zamaratski, Edouard,Odell, Luke R.

, p. 5402 - 5408 (2019/06/27)

Herein, a general, solvent-free and straightforward thiomethylation of electron deficient heterocycles using BF3·SMe2 as a dual thiomethyl source and Lewis acidic activator is presented. A range of heterocycles including pyrimidine, pyrazine, pyridazine, thiazole and purine derivatives were successfully substituted using this method. An unexpected reductive property of BF3·SMe2 towards nitropyridines was also discovered including an intriguing tandem reduction/SMe insertion process in certain substrates. Notable features of the present work include its convenience and use of a non-malodorous reagent while the discovery of novel chemical transformations using BF3·SMe2 provides fundamental new insights into the reactivity of this commonly employed reagent.

Identification of RO4597014, a glucokinase activator studied in the clinic for the treatment of type 2 diabetes

Qian, Yimin,Corbett, Wendy L.,Berthel, Steven J.,Choi, Duk Soon,Dvorozniak, Mark T.,Geng, Wanping,Gillespie, Paul,Guertin, Kevin R.,Haynes, Nancy-Ellen,Kester, Robert F.,Mennona, Francis A.,Moore, David,Racha, Jagdish,Radinov, Roumen,Sarabu, Ramakanth,Scott, Nathan R.,Grimsby, Joseph,Mallalieu, Navita L.

supporting information, p. 414 - 418 (2013/07/25)

To resolve the metabolite redox cycling associated with our earlier clinical compound 2, we carried out lead optimization of lead molecule 1. Compound 4 showed improved lipophilic ligand efficiency and demonstrated robust glucose lowering in diet-induced obese mice without a liability in predictive preclinical drug safety studies. Thus, it was selected as a clinical candidate and further studied in type 2 diabetic patients. Clinical data suggests no evidence of metabolite cycling, which is consistent with the preclinical profiling of metabolism.
