Abstract
U okviru ove disertacije opisana je priprava 3-hidroksiimino-, 3-dodecilamino, 3- (N,N-dimetilkarbamoiloksi)-, 3-(N,N-dietilkarbamoiloksi), 3-(N-fenilkarbamoiloksi)-, te 3- (N,N-difenilkarbamoiloksi)kinuklidina, kao i 2-(kinuklidin-3-iliden)kinuklidin-3-ona i njegovog ketoksima. Spojevi su sintetizirani klasičnim postupcima organske sinteze, a ketoksim kinuklidina i mehanokemijskom sintezom. Ispitan je potencijal mehanokemijske sinteze oksima na nizu aldehida i ketona koji u svojoj strukturi imaju dušikove atome različite bazičnosti te je pokazano da su reakcije moguće uz katalitičku količinu otapala i bez dodatka baze. Nadalje, kvaternizacijom spojeva s metil-jodidom, but-3-en-1-il-bromidom i različito para i meta supstituiranim benzil-bromidima pripravljena su 42 derivata, od kojih 37 do sada nisu opisani u literaturi. Svi pripravljeni spojevi dobiveni su u zadovoljavajućem iskorištenju te im je struktura dokazana standardnim analitičkim metodama, a primjenjena je i spektroskopija nuklearne magnetske rezonancije za određivanje optičke čistoće kiralnih amina. Svi spojevi su pokazali bioaktivnost: oksimi i amini antibiotski potencijal, a karbamati inhibicijski potencijal prema kolinesterazama. Molekulskim modeliranjem određen je način vezanja N,N-dimetilkarbamata u aktivnom mjestu AChE.
Abstract (english)
In this thesis, the syntheses of 3-hydroxiimino-, 3-dodecylamino-, 3-(N,Ndimethylcarbamoyl) oxy-, 3-(N,N-diethylcarbamoyl)oxy-, 3-(N-phenylcarbamoyl)oxy-, 3- (N,N-diphenylcarbamoyl)oxyquinuclidine, as well as the condesation product of quinuclidine-3-on and its ketoxime are described. The possibility of mechanochemical synthesis (without the addition of external base and with catalytic amount of solvent) of oximes from carbonyl compounds that have nitrogen atoms of various bacisity was also determened. Furthermore, prepared compounds were quaternized with methyl iodide, but-3- en-1-yl bromide, and differently substituted meta and para benzyl bromides. 42 compounds were prepared in that manner, from which 37 for the first time. All compounds were prepared in good yields and were characterized by standard analytical methods. Bioactivity of compounds was tested. Oximes and amine derivatives showed antibacterial potential. The interaction of carbamates with cholinesterases was determined experimentaly and the mode of binding of 3-(N,N-dimethylcarbamates within the active site was determined.
