Studies have demonstrated a pos. correlation between inflammation, metastasis, or atherosclerosis and the unbalanced or culminated expression of matrix metalloproteinases (MMPs). The mol. imaging of locally upregulated MMP activity in vivo is a clin. challenge. Actually, radioligands based on nonpeptidyl MMP inhibitors (MMPIs) are currently in development as putative radiopharmaceutical agents for the noninvasive in vivo assessment of activated MMPs. Nonpeptidyl MMPIs bind to the zinc active site of the activated enzyme via mono- (e.g. carboxylate) or bidentate (e.g. hydroxamate) complexation thereby exhibiting a broad-spectrum MMP binding potency. Thus, these mentioned endopeptidase inhibitors should be useable lead compounds for the redevelopment as diagnostic MMPI radiotracers. Recently, the non-hydroxamate C-5-disubstituted pyrimidine-2,4,6-triones were disclosed as subgroup-selective MMP inhibitors. We here describe a set of fine-tuned barbiturates as a new class of MMPI radiotracers for the noninvasive in vivo visualization of activated MMPs using scintigraphic techniques such as SPECT or PET. In the experiment, the researchers used many compounds, for example, 1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8Application In Synthesis of 1-(4-(4-Methoxyphenoxy)phenyl)ethanone).
1-(4-(4-Methoxyphenoxy)phenyl)ethanone (cas: 54916-28-8) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Application In Synthesis of 1-(4-(4-Methoxyphenoxy)phenyl)ethanone
