AB  - The anticancer drug cisplatin (CP) is loaded into SBA-15 mesoporous silica (SBA-15 vertical bar CP) and its release from the nanomaterial is studied. The CP-loaded SBA-15 is tested against four tumor cell lines: mouse malignant melanoma B16F10, human adenocarcinoma HeLa, colon HT-29 and prostate PC3. Most importantly, the superiority of this novel material in comparison to CP arises from the fact that the CP-grafted nanomaterial SBA-15 (-> SBA-15 vertical bar CP) is enhancing cessation of proliferation along with induction of senescence in B16F10 in approximately 3.5 times lower concentration. The control material loaded with therapeutically inactive K-2[PtCl4] (-> SBA-15 vertical bar TC) showed no antitumor activity. To a large extent, SBA15| CP-induced senescence might present a safe approach in tumor treatment. Such cells can be cleared by immune cells resulting in efficient tumor regression. So far only apoptotic agents are being exploited in clinics, thus an understanding of the chemotherapeutic-induced senescence will allow oncologists to explore this essential tumor suppressor mechanism.

AB  - Three novel complexes of platinum(II) with R(2)edda bidentate ligands [PtCl2(R(2)edda)] (R = Me, Et, n-Pr; edda = ethylenediamine-N,N'-diacetate; 1-3), are synthesized and characterized by IR and NMR spectroscopy and elemental analysis. All complexes exist in three stereoisomeric forms (R,R), (S,S) and (R,S)(S,R). In addition crystal structure of one platinum(IV) complex [PtCl4((n-Pr)(2)edda)], 4, is presented. Furthermore, in order to assign stereoisomers of 1-3, a reduction of racemic [PtCl4(Et(2)edda)] by ascorbic acid to [PtCl2(Et(2)edda)] (2) was performed and analyzed by H-1 NMR. Time-depending H-1 NMR spectroscopic experiments were implemented to study the stability of ethylenediamine-N,N'-diacetate diesters. Finally, the in vitro cytotoxic activity of complexes 1-3 was studied on 11 tumor cell lines, 518A2 (melanoma), 8505C (human thyroid carcinoma), A253 (head and neck tumor), A431 (cervix), A549 (lung), A2780 (ovarian), MCF-7 (breast) and HT-29, HCT-8, DLD-1, SW1736 (all colon) by the SRB colorimetric assay method. Complex 3 showed the highest action against ovarian (A2780) cells with an IC50 value 51 +/- 1 mu M.

AB  - Several new R(2)eddp (R = i-Pr, i-Bu; eddp = ethylenediamine-N,N'-di-3-propionate) esters and corresponding platinum(II) and platinum(IV) complexes of the general formula [PtCln(R(2)edda-type)] (n = 2, 4) were synthesized and characterized by spectroscopic methods (IR, H-1 and C-13 NMR) and elemental analysis. The crystal structure of platinum(IV) complex [PtCl4{(c-Pe)(2)eddip}] (3a) was resolved and is given herein. Ligand precursors, platinum(II), and platinum(IV) complexes were tested against eight tumor cell lines (CT26CL25, HTC116, SW620, PC3, LNCaP, U251, A375, and B16). Selectivity in the action of those compounds between tumor and two normal primary cells (fibroblasts and keratinocytes) are discussed. A structure-activity relationship of these compounds is discussed. Furthermore, cell cycle distribution, induction of necrosis, apoptosis, autophagy, anoikis, caspase activation, ROS, and RNS are presented on the cisplatin-resistant colon carcinoma HCT116 cell line.

AB  - The novel N,N-type bidentate ligand precursors, diethyl, dipropyl esters of ethylenediamine-N,N′-diacetic acid dihydrochloride (HOOCCH2NHCH2CH2NHCH2COOH • 2HCl, H2edda • 2HCl), and the corresponding tetrachloroplatinum(IV) complexes, [PtCl4(R2edda)] • H2O (ROOCCH2NHCH2CH2NHCH2COOR, R = Me, Et, n-Pr), were synthesized. The esters coordinated as bidentate ligands via both N donor atoms. The esters, as well as the complexes, have been characterized by infrared, 1H and 13C NMR spectroscopy and elemental analysis. Solid state structures of both dimethyl and diethyl ester platinum(IV) complexes have been determined by X-ray crystallography. Quantum chemical calculations were performed in order to investigate diastereoselectivity in the formation of the platinum(IV) complexes. The in vitro cytotoxic evaluation of the investigated complexes in human tumor cell lines 1411HP, H12.1 (both testicular germ cell tumors), DLD-1 (colon carcinoma), 518A2 (melanoma), A549 (lung carcinoma) and liposarcoma showed a dose-dependent antiproliferative effect in all cell lines. Remarkably, the highest cytotoxic activity was observed in the cisplatin-resistant cell line 1411HP. In addition, at higher concentrations the treatment with these complexes led to the induction of apoptosis in all cell lines except for DLD-1.

AB  - Four dipeptide complexes of the type [PtX2(dipeptide)] · H2O (X = Cl, I, dipeptide = l-methionylglycine, l-methionyl-l-leucine) were prepared. The complexes were characterized by 1H, 13C, 195Pt NMR and infrared spectroscopy, DTG and elemental analysis. From the infrared, 1H and 13C NMR spectroscopy it was concluded that dipeptides coordinate bidentately via sulfur and amine nitrogen donor atoms. Confirmed with 13C and 195Pt NMR spectroscopy, each of the complexes exists in two diastereoisomeric forms, which are related by inversion of configuration at the sulfur atom. The 1H NMR spectrum for the platinum(II) complex with l-methionylglycine and chloro ligands exhibited reversible, intramolecular inversion of configuration at the S atom; ΔG≠ = 72 kJ mol−1 at coalescence temperature 349 K was calculated. In vitro cytotoxicity studies using the human tumor cell lines liposarcoma, lung carcinoma A549 and melanoma 518A2 revealed considerable activity of the platinum(II) complex with l-methionylglycine and chloro ligands. Further in vitro cytotoxic evaluation using human testicular germ cell tumor cell lines 1411HP and H12.1 and colon carcinoma cell line DLD-1 showed moderate cytotoxic activity for all platinum(II) complexes only in the cisplatin-sensitive cell line H12.1. Platinum uptake studies using atomic absorption spectroscopy indicated no relationship between uptake and activity. Potential antitumoral activity of this class of platinum(II) complexes is dependent on the kind of ligands as well as on tumor cell type.

AB  - The reaction of solutions of tetraalkyl ethylenediamine-N,N,N′, N′-tetraacetate esters (alkyl = Me, 1a; Et, 1b) with H 2[PdCl4] led to the complexes [PdCl2(R 4EDTA)] (R = Me, 2a; Et, 2b). The coordination of R4EDTA ligands to palladium(II) ions occurs through the two nitrogen donor atoms, as confirmed by IR, 1H and 13C NMR spectroscopies and X-ray crystallography.
