And the article was included in Bioorganic & Medicinal Chemistry Letters in 2015.Quality Control of 1-Methyl-3-nitro-1H-pyrazole This article mentions the following:
A new series of 2,4-diamino pyrimidine derivatives with a sulfone-substituted pyrazole right side-chain were discovered as potent anaplastic lymphoma kinase inhibitors. Structure-activity relationship of the left side-chain on Ph substitutions were explored which delivered many potent ALK inhibitors. Among them, I showed favorable pharmacokinetic profiles in rats and dogs together with significant antitumor efficacy in EML4-ALK fusion xenograft model. In the experiment, the researchers used many compounds, for example, 1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1Quality Control of 1-Methyl-3-nitro-1H-pyrazole).
1-Methyl-3-nitro-1H-pyrazole (cas: 54210-32-1) belongs to pyrazole derivatives. As is the case with imidazoles, the pyrazole ring offers many opportunities to create new multiring systems that incorporate this heterocycle. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, antidiabetic and antibacterial activities.Quality Control of 1-Methyl-3-nitro-1H-pyrazole
