Pyrazoles are synthesized by the reaction of \u03b1,\u03b2-unsaturated aldehydes with hydrazine and subsequent dehydrogenation. 2075-46-9, formula is C3H3N3O2, Name is 4-Nitro-1H-pyrazole. Substituted pyrazoles are prepared by condensation of 1,3-diketones with hydrazine (Knorr-type reactions). For example, acetylacetone and hydrazine gives 3,5-dimethylpyrazole.

Williamson, Douglas S.;Smith, Garrick P.;Mikkelsen, Gitte K.;Jensen, Thomas;Acheson-Dossang, Pamela;Badolo, Lassina;Bedford, Simon T.;Chell, Victoria;Chen, I-Jen;Dokurno, Pawel;Hentzer, Morten;Newland, Samantha;Ray, Stuart C.;Shaw, Terry;Surgenor, Allan E.;Terry, Lindsey;Wang, Yikang;Christensen, Kenneth V. research published \u300a Design and Synthesis of Pyrrolo[2,3-d]pyrimidine-Derived Leucine-Rich Repeat Kinase 2 (LRRK2) Inhibitors Using a Checkpoint Kinase 1 (CHK1)-Derived Crystallographic Surrogate\u300b, the research content is summarized as follows. Inhibitors of leucine-rich repeat kinase 2 (LRRK2) and mutants, such as G2019S, have potential utility in Parkinson’s disease treatment. Fragment hit-derived pyrrolo[2,3-d]pyrimidines underwent optimization using X-ray structures of LRRK2 kinase domain surrogates, based on checkpoint kinase 1 (CHK1) and a CHK1 10-point mutant. (2R)-2-Methylpyrrolidin-1-yl derivative I<\/strong> (LRRK2 G2019S cKi<\/sub> 0.7 nM, LE 0.66) was identified, with increased potency consistent with an X-ray structure of 18\/CHK1 10-pt. mutant showing the 2-Me substituent proximal to Ala147 (Ala2016 in LRRK2). Further structure-guided elaboration of I<\/strong> gave the 2-[(1,3-dimethyl-1H-pyrazol-4-yl)amino] deriv II<\/strong>. Optimization of II<\/strong> afforded diastereomeric oxolan-3-yl derivatives III<\/strong> and IV<\/strong>, which demonstrated a favorable in vitro PK profile, although they displayed species disconnects in the in vivo PK profile, and a propensity for P-gp- and\/or BCRP-mediated efflux in a mouse model. Compounds III<\/strong> and IV<\/strong> demonstrated high potency and exquisite selectivity for LRRK2 and utility as chem. probes for the study of LRRK2 inhibition.<\/p>\n

SDS of cas: 2075-46-9<\/a>, 4-Nitro-1H-pyrazole, also known as 4-Nitropyrazole, is a useful research compound. Its molecular formula is C3H3N3O2 and its molecular weight is 113.08 g\/mol. The purity is usually 95%.<\/p>\n

4-Nitropyrazole, is a building block for the synthesis of various pharmaceutical compounds, including inhibitors, and therapeutic agents. It can be used for the synthesis of highly selective, brain-penetrant aminopyrazole LRRK2 Inhibitor, as a potentially viable treatment for Parkinson’s disease., 2075-46-9.<\/p>\n
