We have synthesized two thiourea derivatives of methyl anthranilate (1, 2) and their complexes with nickel (3) and platinum(II) (4). We have also prepared the complexes of nickel(II) with two benzoylthiourea derivatives (5, 6). The obtained compounds were characterized by elemental analysis, spectroscopic methods (FT-IR, UV-vis, NMR), mass spectrometry and(More)
Many currently available antifungal and antibacterial agents have undesirable toxic effects, and a wide spread use of these drugs has lead to rapid development of drug resistant strains which are the leading cause for treatment failure in both clinical and agricultural applications. The present article provides a synopsis of recent progress in(More)
We have synthesized a series of ligands (1, 3, 4, 6 and 7) and some of their complexes with Ni(II), Cu(II) and Pt(II) (2, 5, 8 and 9). These compounds were studied and characterized by elemental analysis, IR and UV-Vis spectra, conductivity measurements in solution, FAB+/MS, 1H and 13C NMR, ESR, etc. Compound 7 crystallized in the orthorhombic space group(More)
The thiourea derivatives of N-butylmethylamine (3-benzoyl-1-butyl-1-methyl-thiourea) (1), N-ethylisopropylamine (3-benzoyl-1-ethyl-1-isopropyl-thiourea) (2) and the corresponding complexes of 1 and 2 with Ni(II), Co(III) and Pt(II) have been synthesized. The compounds obtained were characterized by elemental analysis, spectroscopic methods (FT-IR, UV-Vis(More)
Based on the ability of bile acids to vectorialize the cytostatic activity of other agents, we have designed and synthesized a new series of platinum and gold complexes. These compounds were studied and characterized by elemental analysis, FT-IR, FAB(+)/MS, 1H, 13C and 195Pt NMR, UV-Vis spectroscopy and conductivity measurements in solution, among other(More)
This article explores the potential cytotoxic activity of bile-acid cisplatin derivatives like bisursodeoxycholate(ethylenediamine)platinum(II), PtU2, when conjugated with gold nanoparticles, being a promising alternative to cisplatin in the treatment of cancer due to their lower toxicity. For our purpose we analyzed the intracellular delivery ability of(More)
With a view to using bile acids as shuttles for delivering platinum-related cytostatic drugs to liver tumors, a chenodeoxycholylglycinato(CDCG)-derivative of platinum(II) has been synthesized. The complex - named Bamet-M2- was chemically characterized by elemental analysis, FT-IR, NMR, FAB-MS, and UV spectroscopy. The results indicate the following(More)
Here, we present a two novel fluorescent dyes ethylenediaminechlorocholylglycinateplatinum(II), [Pt(CG)Cl(en)] complex 1 and bisursodeoxycholate(ethylenediamine)platinum(II), [Pt(UDC)(2)(en)] complex 2 based on well-known cis-platin chemistry. These platinum complexes contain cholylglycinate (CG) and ursodeoxycholate (UDC) as ligands. These compounds enable(More)
Cisplatin is one of the chemotherapeutic agents used the most for testicular, ovarian and several other cancers. In order to overcome cisplatin resistance, other platinum (Pt) compounds have been developed and, in the last ten years, Pt-derivatives with reporting activity have also been synthesized. The first generation of reporting Pt-compounds was based(More)
SUMMARY In this paper we present our experience in the development of a web-based business intelligence tool according to the Associative Query Logic paradigm, which can represent large amounts of data in a way that allows extremely fast queries. It has been developed as an open-source, multi-platform software, relying on data compression techniques for the(More)
