Rigidified acetylcholine mimics: conformational requirements for binding to neuronal nicotinic receptors
摘要:
Rigidified derivatives have been designed and synthesized assuming the g + t conformer of acetylcholine (N-C-C-O = + 60degrees, C-C-O-C = 180degrees) as active conformation for binding to cytisine sensitive neuronal nicotinic receptors. The SAR of the compounds evaluated, along with those of more flexible analogues, support the g + t conformer hypothesis and highlight the stringent steric limitation of this nicotinic receptor sub-type. Compound 3e has low muM affinity for cytisine sensitive nicotinic receptor binding sites while being selective with regard to the a-bungarotoxin sensitive subclass. We also report few compounds with muM affinity for the a-bungarotoxin sensitive subclass. (C) 2003 Elsevier Ltd. All rights reserved.
The present invention relates to substituted 5-membered nitrogen containing heteroaryl compounds, such as sulfonyl triazoles, where the heteroaryl ring is further substituted, optionally via a linking group such as -NH-, with a cyclic group which in turn is substituted at the α-position. The present invention further relates to associated salts, solvates, prodrugs and pharmaceutical compositions, and to the use of such compounds in the treatment and prevention of medical disorders and diseases, most especially by NLRP3 inhibition.

The compounds are of the heterocyclic class of 2-phenethylpiperidines having an amido substituent in the ortho position of the phenethyl moiety. Substituents in the ortho position include formamido, benzamido, cinnamamido, 2-thiophenecarboxamido, alkanesulfonamido and alkanoylamido. They are useful as antiarrhythmic and/or antiserotonin agents. The novel compounds are prepared by reaction of appropriately substituted o-aminophenethylpiperidines and the carbonyl or sulfonyl halides or anhydrides. Typical embodiments of this invention are 4-methoxy-2'-[2-(1-methyl-2-piperidyl)ethyl]benzanilide and 2'-[2-(1-methyl-2-piperidyl)ethyl]cinnamanilide.

2D NMR (NOESY, COSY, HSQC and HMBC) spectra which enabled to distinguish the isomers and to exclude retro-Smiles rearrangement and the azine nitrogen atom alkylation pathways. This supposition was fully confirmed by X-ray analysis showing the quinobenzothiazine system to be folded and the substituent at the thiazine nitrogen atom in an equatorial position. Some compounds exhibited anticancer activity
