In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthesis, Radiofluorination, and In Vitro Evaluation of Pyrazolo[1,5-a]pyridine-Based Dopamine D4 Receptor Ligands: Discovery of an Inverse Agonist Radioligand for PET, published in 2008-03-27, which mentions a compound: 56621-48-8, mainly applied to pyrazolopyridine arylpiperazinylmethyl preparation radiofluorination dopamine receptor radioligand, Synthetic Route of C10H14N2O.
A series of fluoro-substituted analogs structurally derived from the aminomethyl-substituted pyrazolo[1,5-a]pyridine lead compounds FAUC 113 and FAUC 213 were synthesized and evaluated as high-affinity D4 receptor (D4R) ligands (Ki = 1.3-28 nM). The para-fluoroethoxy-substituted derivatives I and II revealed an outstanding D4 subtype selectivity of more than 3 orders of magnitude over both congeners D2 and D3 combined with inverse agonism at D4R. The corresponding 18F-labeled radioligands revealed high serum stability in vitro and log P values of 2-3. In vitro rat brain autoradiog. showed specific binding of [18F]-II in distinct brain regions, including the gyrus dentate of the hippocampus, that were inhibited by both eticlopride (65-80%) and the selective D4R antagonist 10 (78-93%). The observed binding pattern was mainly consistent with the known D4R distribution in the rat brain. Thus, [18F]-II (FAUC F41) represents a potential radioligand for studying the D4R in vivo by positron emission tomog. (PET).
Although many compounds look similar to this compound(56621-48-8)Synthetic Route of C10H14N2O, numerous studies have shown that this compound(SMILES:OC1=CC=C(N2CCNCC2)C=C1), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
