Abstract
Zbog svoje važne biološke aktivnosti promatran je i ispitivan vitamin B6 i njegovi derivati. Važnost vitamina B6 očituje se u normalnom funkcioniranju živčanog sustava te normalnom funkcioniranju metabolizma lipida, glukoze, aminokiselina. Bitnu ulogu ima i u brojnim enzimskim aktivnostima. Molekula piridoksala pruža široke mogućnosti za kemijske modifikacije i pripravu derivata sa značajnim farmakološkim djelovanjem. U radu se pripravljeni derivati piridoksal hidroklorida. Prvo su sintetizirani N-acilhidrazoni (1-8), reakcijom piridoksala sa N-acilhidrazinima aromatskih i heteroaromatskih spojeva. Reakcije su rađene klasičnim putem, miješanjem u etanolu na sobnoj temperaturi 24 sata. U drugom dijelu rada se dobiveni hidrazoni kvaterniziraju s ciljem dobivanja kvaternih soli. Za kvaternizaciju se koriste fenacil-bromidi i supstituirani fenacil-bromidi. Sinteza se izvodi klasičnim putem, miješanjem i zagrijavanjem pri temperaturi refluksa otapala. Svi dobiveni spojevi su pročišćeni i snimljeni su im IR, MS, 1H i 13C NMR spektri, te im je određena temperatura tališta.
Abstract (english)
Because of its important biological activity, vitamin B6 and its derivatives have been observed and investigated. The importance of vitamin B6 is manifested in the normal functioning of the nervous system and the normal functioning of the metabolism of lipids, glucose, and amino acids. It also plays an important role in numerous enzymatic activities. The pyridoxal molecule offers wide possibilities for chemical modifications and the preparation of derivatives with significant pharmacological activity. Pyridoxal hydrochloride derivatives are prepared in this work. First, N-acylhydrazones (1-8) were synthesized, by reacting piridoxal with N-acylhydrazines of aromatic and heteroaromatic compounds. The reactions were carried out in the classic way, by stirring in ethanol at room temperature for 24 hours. In the second part of the work, the obtained hydrazones are quaternized with the aim of obtaining quaternary salts. Phenacyl bromides and substituted phenacyl bromides are used for quaternization. The synthesis is carried out in the classical way, by mixing and heating at the reflux temperature of the solvent. All obtained compounds were purified and their IR, MS, 1H and 13C NMR spectra were recorded, and their melting point was determined.
