NOVEL ANTIOXIDANTS BASED ON SELECTED 3D METAL COORDINATION COMPOUNDS WITH 2-HYDROXYBENZALDEHYDE 4,S-DIALLYLISOTHIOSEMICARBAZONE
(2023) Graur, Vasilii; Mardari, Anastasia; Bourosh, Pavlina; Kravtsov, Victor; Usataia, Irina; Ulchina, Ianina; Garbuz, Olga; Gulea, Aurelian
2-Hydroxybenzaldehyde 4,S-diallylisothiosemicarbazone (HL) was synthesized and characterized by 1H, 13C NMR and FTIR spectroscopies. It exists in solution in two isomeric forms: cis (~25%) and trans (~75%). Six stable complexes were obtained by interaction of HL with copper(II), nickel(II), cobalt(III) and iron(III) salts: [Cu(L)Cl] (1), [Cu(L)NO3] (2), [Cu(3,4-Lut)(L)NO3] (3), [Ni(L)OAc] (4), [Co(L)2]Cl (5), [Fe(L)2]NO3 (6). The synthesized complexes have been studied by elemental analysis, FTIR, molar electrical conductivity and single crystal X-ray diffraction (6). For all compounds the antioxidant activity against cation radicals ABTS•+ was studied. All complexes and free ligand are more active than trolox that is used in medicine practice. Complex 4 (IC50=7.20µM) is the most active one. The introduction of heterocyclic amine did not improve the antioxidant activity. The introduction of S-allyl group into isothiosemicarbazone affected the activity of the synthesized substances, and in some cases the resulting complexes exhibit greater activity than complexes with isothiosemicarbazones with other S-radicals.

The new isothiosemicarbazones were characterized by NMR, FTIR spectroscopy, and X-ray crystallography ([H2L2]I). All copper(II) coordination compounds were characterized by elemental analysis, FTIR spectroscopy, and molar conductivity of their 1mM methanol solutions. Furthermore, the crystal structure of complex 3 was determined using single-crystal X-ray diffraction analysis. The studied complexes manifest antibacterial and antifungal activities, that in many cases are close to the activity of medical drugs used in this area, and in some cases even exceed them. The complexes 4 and 5 showed the highest indexes of selectivity (280 and 154) and high antiproliferative activity against BxPC-3 cell lines that surpass the activity of Doxorubicin. The complexes 1–3 also manifest antioxidant activities against cation radicals ABTS•+ that are close to that of trolox, the antioxidant agent used in medicine.

The new N-(4-methoxyphenyl)-2-oxopropanamide 4-phenylthiosemicarbazone (HL) and its 5 copper(II) coordination compounds [Cu(L)X] (X = Cl- (I); Br- (II); NO3- (III); CH3COO- (IV); Cl2CHCOO- (V)) have been synthesized and characterized by elemental analysis, FTIR and NMR spectra. Coordination of 4-phenylthiosemicarbazone HL with the copper(II) atom led to increased antibacterial activity against Staphylococcus aureus and Bacillus cereus. Non-coordinated 4-phenylthiosemicarbazone (HL) showed the highest activity in relation to ABTS•+ cation radicals; its activity is close to that of Trolox, which is used in medicine. The antibacterial and antioxidant activities of the synthesized complexes are influenced by the nature of the acidic residue in their composition.

Moreover, it manifests high antioxidant activity towards ABTS•+ radical cation that exceeds the activity of trolox.

New zinc(II), copper(II), nickel(II), iron(III), and cobalt(III) coordination compounds, [Zn(HL)I2] (1), [Cu(HL)Cl2] (2), [Cu(HL)Br2] (3), {[Cu(HL)NO3]NO3}n (4), [Ni(HL)2](NO3)2 (5), [Fe(L)2]NO3(6), [Co(L)2]NO3 (7), and [Co(L)2]Cl·H2O (8), were obtained with 2-acetylpyridine N4-allyl-S-methylisothiosemicarbazone (HL). The isothiosemicarbazone proligand was characterized by nuclear magnetic resonance (NMR) (1H and 13C), infrared (IR) spectroscopy, and X-ray diffraction. All the coordination compounds were characterized by elemental analysis, IR, UV–Vis spectroscopy, molar conductivity, and magnetic susceptibility measurements. Single-crystal X-ray diffraction analysis elucidated the structure of the cationic form of the proligand in the salt [H2L]I and compounds 1–4 and 8 and demonstrated an unusual way of coordination through methylated sulfur atom in 1 and 3. Nevertheless, the electron paramagnetic resonance (EPR) and UV–Vis investigations showed that this way of coordination quickly changes upon dissolution of coordination compounds in dimethyl sulfoxide (DMSO). The antiproliferative properties of these compounds towards human cervical epithelial HeLa, human epithelial pancreatic adenocarcinoma BxPC-3, human muscle rhabdomyosarcoma spindle, large multinucleated RD cancer cell lines, and normal kidney epithelial MDCK cell line have been investigated. Copper coordination compounds (2–4) show promising anticancer activity with high selectivity (selectivity index [SI] = 10–18) towards BxPC-3 cell line. They also possess significant antibacterial and antifungal activity, which is useful for cancer treatment.

2-Hydroxybenzaldehyde-4-allyl-S-methylisothiosemicarbazone and Cu (II), Co (III), Fe (III) and Cr (III) complexes were synthesized and characterized. The new obtained compounds were investigated by elemental analysis, magnetic susceptibility measurements, molar electric conductivity, IR, 1H NMR, 13C NMR, UV–Vis spectroscopy. In addition, the structure of the ligand and six complexes has been determined by single-crystal X-ray diffraction analysis. The Cu atom in complex 3 is penta-coordinated in a distorted square–pyramidal coordination geometry, while the metals in complexes 5–9 are in a distorted octahedral environment. For all compounds the antimicrobial activity was studied on a series of standard strains, such as Staphylococcus aureus, Escherichia coli, Enterococcus faecalis, Salmonella abony and Candida albicans. The in vitro antiproliferative activity of the ligand and complexes was screened on human leukemia HL-60 cells, human cervical epithelial HeLa cells, human epithelial pancreatic adenocarcinoma BxPC-3 cells, human muscle rhabdomyosarcoma spindle and large multinucleated RD cells. The primary screening on a wider series of cancer cells showed that copper coordination compound 2 manifests high activity towards HeLa, BxPC-3 and RD cancer cells, which is three–six times higher than the activity of doxorubicin. The selectivity index that is the ratio between the IC50 value for the normal MDCK cells and IC50 values for the cancer cells varies in the range 2.44–21.17. This index is 5.5–11 times higher for the copper coordination compound 2 than for the doxorubicin. Cr (III), Fe (III) and Co (III) coordination compounds 6–9 manifest high antioxidant activity towards ABTS•+ that exceeds 47–67 times the activity of Trolox.

N-(Prop-2-en-1-yl)hydrazonocarbothioamide reacts with iodoethane in methanol with further addition of 2-hydroxybenzaldehyde to form hydroiodide of carbamohydrazonothioate (HL·HI). The coordination compounds were obtained by interaction of HL or HL·HI with copper, nickel, cobalt and iron salts CuLХ·nH2O [X = Cl–, Br–, NO3–; n = 0–1], Ni(L)2·HI·CH3OH, Сo(L)2X [X = I–, NO3–] and Fe(L)2NO3. The structures of three complexes were established by single crystal X-ray analysis. The synthesized complexes exhibit selective antimicrobial and antifungal activity against a series of standard microorganisms and fungi in the concentration range of 30–500 μg/mL. In addition, nickel and iron complexes selectively inhibit the growth and proliferation of cancer cells and do not adversely affect normal cells.
