Abstract
U ovom radu opisana je sinteza novih derivata benzimidazola i strukturna karakterizacija 1H i 13C-NMR spektroskopijom s ciljem ispitivanja njihovog antitumorskog i antibakterijskog djelovanja. Ključni prekursori 4-O-alkilirani benzaldehidi (1-6) pripravljeni su reakcijom O-alkiliranja 4-hidroksibenzaldehida a odgovarajućim haloalkilirajućim reagensima u acetonitrilu, uz K2CO3 kao bazu. Reakcijom N-klormorfolina s natrijevim azidom priređen je N-azidoetilmorfolin (7). O-alkiliranjem 4-hidroksibenzaldehida s propargil-bromidom u suhom etanolu uz K2CO3 kao bazu sintetizirani su 4-O-propargilbenzaldehidi (8 i 9). Huisgenovom 1,3-dipolarnom ciloadicijom 4-O-propargilbenzaldehida (8 i 9) s N-azidoetilmorfolinom (7) uz Cu(OAc)2 kao katalizator pripavljeni su 1,2,3-triazolni derivati benzaldehida (10 i 11). Reakcijom ciklizacije potpomognutom ultrazvukom O-alkiliranih benzaldehida (1-6) uz K2CO3 kao bazu i Na2S2O5 priređeni su derivati benzimidazola s odgovarajućim arilnim supstituentima u položaju 2 benzimidazolnog prstena (12-14, 16-27, 29-35). Strukture svih pripravljenih spojeva potvrđene su 1H i 13C-NMR spektroskopijom. Farmakološki učinci i moguće biološke mete novopripravljenih spojeva predviđene su in silico analizom (PASS).
Abstract (english)
This paper describe the synthesis of novel benzaldehyde derivatives and structural characterization by 1H and 13C-NMR spectroscopy in order to examine their antitumor and antibacterial activities. Key precursors 4-O-alkylbenzaldehydes (1-6) were prepared by reaction of O-alkylation 4-hydroxybenzaldehyde with corresponding haloalkylating reagents in the presence K2CO3 as base. In reaction of N-chloromorpholine with sodium azide N-azidoethylmorpholine (7) was obtained. O-alkylation reaction of 4-hydroxybenzaldehyde with propargyl bromide in dry ethanol with K2CO3 as a base gave 4-O-alkylbenzaldehydes (8-9). 1,2,3-triazole benzaldehyde derivatives (10 i 11) were synthesized by Huisgen 1,3-dipolar cycloaddition of O-alkylbenzaldehydes (8 i 9) and N-azidoethylmorpholine (7) in the presence of Cu(OAc)2 as catalyst. Benzimidazole derivatives substituted with appropriate aril substituents in position 2 of benzimidaze ring (12-14, 16-27, 29-35) were prepared by cyclization reaction of O-alkylbenzaldehydes (1-6) with K2CO3 as base and Na2S2O5 supported with ultrasound of The structures of all newly prepared compounds were confirmed by 1H and 13C-NMR spectroscopy. Pharmacological effects and possible biological targets of novel compounds are predicted by in silico analysis (PASS).
