AB  - Fourteen novel N-benzylpiperidine and N,N-diarylpiperazine conjugates were synthesized and pharmacologically evaluated as donepezil analogs, in a ligand-based drug design approach. All compounds possessed high to moderate in vitro inhibitory activity with IC50 in range 2.3–20 µM and selectivity towards acetylcholinesterase, while being inactive towards butyrylcholinesterase. Structure-activity relationship analysis revealed the influence of N,N-diarylpiperazine moiety and the linker connecting two pharmacophores on the inhibitory activity. Kinetic studies on the two most active compounds 7g and 8g (IC50 = 2.3 and 4 µM, respectively) revealed mixed type mode of inhibition, binding to both, free enzyme and enzyme-substrate complex. For further understanding of mechanism of action and binding orientations, molecular docking was performed for all compounds, while the ligand transport simulation and molecular dynamics simulations were performed for 7g and 8g. Computational results corroborated well with in vitro activities and kinetic studies.

AB  - The synthetic route toward novel tricyclic, nitrogen-containing system is disclosed. Three novel compounds possessing structural features of 1,2,3,4-tetrahydroquinoxaline and decahydropyrido[3,4-b]pyrazine are synthesized starting from readily available precursors in six or seven steps, of which the last three or four steps respectively are diastereoselective. Key reaction steps include N-acylation, Hofmann rearrangement and ring-closing Buchwald– Hartwig reaction. Compounds trans-8, cis-12 and trans-12 are synthesized in order to prove that this novel, tricyclic system can be functionalized with various groups. Synthetic significance of this heterocyclic system lies in the possibility for the orthogonal functionalization of three different amino groups, allowing fine structural tuning.
AB  - У овом раду представљена је синтеза новог трицикличног система који садржи азот.  Три нова једињења код којих су комбиноване структурне карактеристике 1,2,3,4-тетрахидрохиноксалина и декахидропиридо[3,4-b]пиразина, добијена су полазећи од лако доступних прекурсора, у шест или седам фаза од којих су последње три или четири,  редом, диастереоселективне. Кључне синтетичке трансформације укључују N-ациловање, Hofmann премештање и интрамолекулску Buchwald–Hartwig реакцију, као фазу у којој долази до циклизације. Једињења trans-8, cis-12 и trans-12 су синтетисана како би се представила могућност функционализације новог трицикличног система. Синтетички значај новог хетероцикличног система представљен је у могућности ортогоналне функционализације три различите амино групе, чиме се може постићи фино подешавање структуре.

AB  - Alzheimer’s disease (AD) is a neurodegenerative disease which affects over 50 milion people worldwide.1) AD
mainly affects people ages 65 and above. Symptoms are memory loss, decline in learning capacity, and language
problems. One of currently available treatments for Alzheimer's disease consists of Cholinesterase (ChEIs)
inhibitors, which raise acetylcholine levels in the brain. The drugs currently approved by the FDA for this
purpose are donepezil, rivastigmine and galantamine.
As a part of our research we designed and synthesized seven novel compounds (6a-g) as potential
acetylcholinesterase inhibitors (AChEIs). The compounds contain N-benzyl piperidine moiety, which is common
in many inhibitors including donepezil,2) and N-aryl piperazine moieties.
