Abstract
U okviru ovog diplomskog rada ispitana su inhibitorna svojstva 11 novih heterocikličkih α-D-manopiranozida. Aktivnost liofilizirane butirilkolinesteraze izolirane iz konjskog seruma (EqBChE, akt. 0,08 U/mL) određena je spektrofotometrijskom metodom po Ellmanu. Mjerenja aktivnosti su vršena uz acetiltiokolin-jodid kao supstrat (u konc. rasponu 0,04 – 1 mM), tiolni reagens DTNB (0,3 mM) i spojeve 1 – 11 (10 – 300 μM). Povećanje apsorbancije TNB aniona praćeno je u kvarcnim kivetama (ukupni volumen reakcijske smjese 2 mL) u 0,1 M fosfatnom puferu (pH 7,4) pri 25 oC i valnoj duljini 412 nm kroz 90 sekundi na spektrofotometru AnalytikJena Specord 200. Od jedanaest ispitanih spojeva, šest je pokazalo inhibitornu aktivnost prema EqBChE, od kojih su dva relativno dobri inhibitori s konstantama inhibicije 12,40±1,226 μM (za spoj 7) i 37,28±3,982 μM (za spoj 4).
Abstract (english)
The aim of this thesis is to investigate inhibitory properties of 11 newly synthesized heterocyclic α-D-mannopiranosides towards BChE. Ellman's spectrophotometric method was used to determine activities of lyophilized butyrylcholinesterase from equine serum (EqBChE, act. 0,08 U/mL). Measurments were conducted with acetylthiocholine iodide as a supstrate (conc. range 0,04 – 1 mM), thiol reagent DTNB (0,3 mM) and compounds 1 -11 (10 – 300 μM). Increase in TNB anion absorbance was monitored in quartz cuvettes (total volume 2 mL) in 0,1 M phosphate buffer medium (pH 7,4) at 25 oC and wavelength 412 nm during 90 seconds on AnalytikJena Specord 200 spectrophotometer. Six out of eleven tested compounds have shown inhibitory effect on BChE and two of them are relatively good BChE inhibitors with constants of inhibition 12,40±1,226 μM (compound 7) i 37,28±3,982 μM (compound 4).
