Abstract
Biofilm je zajednica različitih vrsta mikroorganizama koji su uklopljeni u matriks. Matriks predstavlja fizičku barijeru koja otežava penetraciju antibiotika do ciljnih stanica, a s druge strane, zbog viskoelastičnosti otežano je mehaničko uklanjanje. Navedeno čini biofilm kako zdravstvenim, tako i industrijskim problemom s obzirom da se može formirati na bilo kojoj metalnoj ili plastičnoj površini. U ovom radu sintetizirana su tri potencijalna inhibitora biofilma (6-8). Sinteza se odvijala u četiri koraka, a kao početni spoj uzet je harmin. U prvom koraku sinteze Michaelovom adicijom dobiven je ester 1. U idućem koraku u reakciji hidrolize dobivena je kiselina 2. U trećem koraku sinteze reakcijom couplinga između kiseline 2 i odgovarajućeg amina (4-amino-1-Boc-piperidina, 4-(NBoc- amino)piperidina ili N-Bocetilendiamina), uz HATU/DIEA dobiveni su N-Boc zaštićeni amidi (3-5). Boc zaštitna skupina uklonjena je u kiselim uvjetima, uz TFA, te su dobiveni odgovarajući amidi (6-8). Spojevima su određena su tališta, a njihove strukture potvrđene su standardnim spektroskopskim i spektrometrijskim tehnikama (IR, 1H i 13C NMR, MS). U daljnjim istraživanjima, bit će ispitano njihovo inhibitorno djelovanje na bakterijski biofilm.
Abstract (english)
Biofilm is a community consisting of various types of microorganisms embedded in extracellular matrix, which represents a physical barrier that complicates antibiotic penetration to target bacteria. Furthermore, mechanical removal is complicated due to viscoelastic properties of biofilm. Aforementioned makes biofilm a major healthcare, as well as industrial problem, due to the fact that it can be formed on any metal or plastic surface. Three potential biofilm inhibitors have been synthetized (6-8). Synthesis was done in a four step procedure using harmine as a starting compound. The first step included Michael reaction resulting in esther 1, which was subsequently hydrolised to give acid 2. The third step included coupling reaction between acid 2 and corresponding amine (4- amino-1-Boc-piperidine, 4-(N-Boc-amino)piperidine or N-Boc-ethylenediamine), in the presence of HATU/DIEA, resulting in N-Boc protected amides (3-5). Boc protective group was removed under acid conditions, (TFA), to yield final compounds, amides (6-8). Melting points of new compounds were determined and their structures were confirmed using standard spectroscopic and spectrometric techniques (IR, 1H and 13C NMR, MS). Their inhibitory activity on bacterial biofilm will be tested in further studies.
