Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 2495-37-6, Name is Benzyl methacrylate, molecular formula is , belongs to quinuclidines compound. In a document, author is Dolle, F, Product Details of 2495-37-6.
Synthesis and preliminary evaluation of a carbon-11-labelled agonist of the alpha 7 nicotinic acetylcholine receptor
The lead compound of a new series of azabicyclic carbamates described by Astra Laboratories as ligands for the alpha7 nicotinic acetylcholine receptor subtype, namely N-(4-bromophenyl)carbamic acid quinuclidin-3-yl ester, has been labelled with carbon-11 using no-carrier-added [C-11]phosgene and the isocyanate pathway. Typically, 25-35 mCi (0.92-1.29 GBq) of the tracer was obtained within 30 min of radiosynthesis (HPLC purification included) with specific radioactivities ranging from 500 to 800 mCi/mu mol (18.5-29.6 GBq/mu mol). Biodistribution studies demonstrated a relatively good brain uptake of the compound (0.8-1.2% I.D./g tissue in various brain regions), but without preferential concentration in brain regions rich in alpha7-subtype nicotinic receptor (e.g. hippocampus, pons and colliculi). No specific binding could be demonstrated in pre-saturation studies performed with both the cold compound and nicotine. Therefore, this ligand is not suitable for further exploration in PET imaging.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2495-37-6, in my other articles.
