Structuren Medicinale Chemie
I. ACETYLCHOLINE EN DE CHOLINERGE RECEPTOREN




Nicotineagonisten:




1) Een kwaternair of sterk basisch N-atoom
2) Een carbonylgroep of zwak basisch N-atoom
3) 2 bindingsplaatsen in de buurt van de bindingsplaatsen van het kwaternair ammonium ion en
de carbonylgroep die toelaten om de binding te optimaliseren




Nicotineantagonisten:
 Ganglionblokkers




diethyldiisopropylammonium groep




 Neuromusculaire blokkers
o leptocurares




o Pachycurares

,  Lokale anesthetica:
o Esters




o Amiden




Muscarineagonisten:




 Positief geladen groep
 Teriaire aminen: rigide ringstructuur
 Lipofiele (alkyl)groep en electronrijk centrum (estergroep, driedubbele binding /// )

5-atoom model

Muscarinereceptor:
 Anionische bindingsplaats
 Plaats voor vorming van H-brug op  3 Å met ring O van muscarine
 Bindingsplaats op  5.7 Å voor interactie met OH van muscarine (~ C=O van acetylcholine)

Muscarineantagonisten:




 kationisch centrum
 aromatische of alicyclische ring
 aan elkaar gebonden zijn via een “linker”-groep (vb esterfunctie of polymethyleenketen).

 Solanaceae alkaloïden en synthetische analogen

,  Analogen met een gewijzigde tropaanring




 Analogen zonder esterfunctie




De ringen en OH kunnen ≠

 Andere muscarine antagonisten




Of met een fenothiazinering of met een thioxantheenring




Achesterase inhibitoren




Fosforzuurderivaten (malathion, parathion)
