Abstract
Cisplatin je eno izmed osrednjih zdravil za raka, vendar njegovo uporabo omejuje njegova toksičnost. Naša predlagana substanca za blaženje stranskih učinkov cisplatina je galna kislina. V okviru diplomske naloge smo optimizirali postopek za pripravo aromatskega estra in ga uporabili na galni kislini. Postopek je služil kot modelna reakcija za pripajanje galne kisline kot aksialnega liganda na Pt(IV) kompleks. Ker galna kislina ni dobro topna v organskih topilih, smo najprej acilirali njene OH skupine, kar je pričakovano povečalo njeno topnost. Tako ester benzojske kisline in 4-cianofenola kot ester acilirane galne kisline in 4-cianofenola smo pripravili preko kislinskega klorida teh kislin. Kislinske kloride smo pripravili z uporabo oksalil in tionil klorida. Nastanke estrov smo potrdili z 1H NMR analizo.

Title:Preparation of activated aromatic acid derivatives as ligands in antitumor platinum complexes
Abstract:
Cisplatin is one of the most used cancer medicines, but its use is being limited by its toxicity. To mediate its side effects, we proposed the use of gallic acid. In this diploma thesis, we optimized the process for preparation of aromatic esters and used the aforementioned process for the preparation of gallic acid ester. This reaction served as an analogue for the addition of gallic acid to Pt(IV) complex as an axial ligand. Because of gallic acid’s poor solubility in organic solvents, we first acylated its OH groups and in this way increase its solubility. Both benzoic acid ester and gallic acid ester were prepared by first preparing acyl chloride derivatives of those acids. Acyl chlorides were prepared by using either oxalyl or thionyl chloride. Synthesized esters were confirmed by 1H NMR analysis.

Keywords:gallic acid, aromatic acid, antitumor activity, Pt(IV) complex
