In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Discovery of 8-azabicyclo[3.2.1]octan-3-yloxy-benzamides as selective antagonists of the kappa opioid receptor. Part 1, published in 2010-10-01, which mentions a compound: 23794-15-2, Name is 1-(2-chloropyridine-4-yl)ethanone, Molecular C7H6ClNO, Category: piperidines.
Initial high throughput screening efforts identified highly potent and selective kappa opioid receptor antagonist 3 (κ IC50 = 77 nM; μ:κ and δ:κ IC50 ratios >400) which lacked CNS exposure in vivo. Modification of this scaffold resulted in development of a series of 8-azabicyclo[3.2.1]octan-3-yloxy-benzamides showing potent and selectivity κ antagonism as well as good brain exposure. Analog 6c (I) (κ IC50 = 20 nM; μ:κ = 36, δ:κ = 415) was also shown to reverse κ-agonist induced rat diuresis in vivo.
There is still a lot of research devoted to this compound(SMILES：CC(=O)C1=CC(Cl)=NC=C1)Category: piperidines, and with the development of science, more effects of this compound(23794-15-2) can be discovered.
