In 2006,Cole, Andrew G.; Stroke, Ilana L.; Brescia, Marc-Raleigh; Simhadri, Srilatha; Zhang, Joan J.; Hussain, Zahid; Snider, Michael; Haskell, Christopher; Ribeiro, Sofia; Appell, Kenneth C.; Henderson, Ian; Webb, Maria L. published 《Identification and initial evaluation of 4-N-aryl-[1,4]diazepane ureas as potent CXCR3 antagonists》.Bioorganic & Medicinal Chemistry Letters published the findings.Formula: C8H6FNO4 The information in the text is summarized as follows:
The identification and evaluation of aryl-[1,4]diazepane ureas as functional antagonists of the chemokine receptor CXCR3 are described. Specific examples exhibit IC50 values of ∼60 nM in a calcium mobilization functional assay, and dose-dependently inhibit CXCR3 functional response to CXCL11 (interferon-inducible T-cell α chemoattractant/I-TAC) as measured by T-cell chemotaxis, with a potency of approx. 100 nM.Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9Formula: C8H6FNO4) was used in this study.
Methyl 4-fluoro-3-nitrobenzoate(cas: 329-59-9) belongs to methyl benzoate. Methyl benzoate reacts at both the ring and the ester, depending on the substrate. Electrophiles attack the ring, illustrated by acid-catalysed nitration with nitric acid to give methyl 3-nitrobenzoate.Formula: C8H6FNO4Methyl 4-fluoro-3-nitrobenzoate is used to prepare dimethyl 3-nitro-3′,4-oxydibenzoate by reacting with 3-hydroxy-benzoic acid methyl ester.
