Abstract:
The multiple drug resistance is a medical issue which creates today lots of clinical problems in the treatment of patients’ infections with antibiotics, particularly in post surgery stage. This is why a nowadays challenge in medicine is to identify new and possible unconventional ways to combat the failure of treatment of infectious diseases and cancer, induced by multidrug resistance [ Turk D. & all, 2009]. This regards not only the improvement of the medicines molecular and bactericide properties and the development of new and efficient molecular structures, but the development of new vectors to transport them to targets, as well. A group of chemicals whose anticancer properties were recently studied is represented by the hydantoin class. Hydantoin, an imidazolidine derivative is a heterociclyc organic compound which was initially obtained through the reduction of allantoin (an urine constituent). Depending on the nature of substitution on the hydantoin ring, its derivatives possess a wide range of pharmaceutical properties, including antitumor, anti-inflamatory, anti-HIV, hypolipidemic, anti-arrhythmic, and anti-hypertensive activities [Avendano C. & all, 2000]. Lately, the cytotoxic properties of spyrohydantoin derivatives were tested in ovarian and breast cancer cells [Rajic Z.& all, 2006]. The anti-cancer effect of Palladium(II) complex of thiohydantoin was studied on the human colon carcinoma cell lines [Smit B.& all, 2012], as well. Extensive research studies are carried out in order to minimize the side effects of these potential antitumor agents. For this purpose, newly synthesized hydantoin derivatives are proposed for spectroscopic characterization and molecular modeling.In this work, experimental and theoretical FTIR spectra of 5-(3-chlorobenzylidene)-2-thioxoimidazolidin-4-one (C10H7ClN2OS, M=238.69 g/mol), generically called SZ-2 were studied. Comparisons between the solid phase and the liquid phase molecular geometry optimization were also carried out. The UV absorption spectra of the compound in different solvents were examnined.
