Platinum(II)-oxalato complexes of seliciclib (CYC202) derivatives show different cellular effects and lesser adverse effects in mouse lymphoma model than cisplatin. J Biol Inorg Chem 2019; 25:67-73.

Abstract
This work presents a deeper pharmacological evaluation of two formerly prepared and characterized, and highly in vitro cytotoxic platinum(II) oxalato complexes [Pt(ox)(L1)2] (1) and [Pt(ox)(L2)2] (2), containing the derivatives of cyclin-dependent kinase inhibitor (CDKi) seliciclib ((R)-roscovitine, CYC202) coordinating as N-donor carrier ligands, i.e., 2-(1-ethyl-2-hydroxyethylamino)-N6-(4-methoxybenzyl)-9-isopropyladenine (L1) and 2-chloro-N6-(2,4-dimethoxybenzyl)-9-isopropyladenine (L2). The positive results of in vitro cytotoxicity screening on human cancer cell lines (HeLa, HOS, A2780, A2780R, G361 and MCF7 with IC50 at low micromolar levels) published previously, motivated us to perform extended preclinical in vitro experiments to reveal the mechanisms associated with the induction of cancer cell death. In addition, the in vivo antitumor activity was evaluated using the mouse lymphocytic leukaemia L1210 model. The obtained results revealed that complex 1 exceeds the antitumor effect of cisplatin (as for the extension of life-span of mice) and shows far less adverse effects as compared to reference drug cisplatin. The in vitro and ex vivo studies of cellular effects and molecular mechanisms of cell death induction showed that the mechanism of action of complex 1 is essentially different from that of cisplatin. The obtained results showed a possible way how to obtain antitumor active platinum(II) oxalato complexes with better therapeutic profile than contemporary used platinum-based therapeutics.

Abstract
Six novel platinum(II) complexes containing purine-mimetic ligands (5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine (dmtp), 7-isobutyl-5-methyl-1,2,4-triazolo[1,5-a]pyrimidine (ibmtp), 5,7-ditertbutyl-1,2,4-triazolo[1,5-a]pyrimidine (dbtp)) and dicarboxylato ligands (glutarato (glut) or cyclobutane-1,1-dicarboxylato (CBDC)) have been prepared and characterized with multinuclear magnetic resonance (1H, 13C, 15N, 195Pt) NMR, infrared (IR) and X-ray crystallography. Spectroscopic data in solid state and in solution unambiguously confirm the square-planar geometry of Pt(II) with two monodentate N3-bonded 5,7-disubstituted-1,2,4-triazolo[1,5-a]pyrimidine ligands and one O-chelating dicarboxylato ligand. Next, the effect of all the platinum(II) compounds on the viability of normal or cancer cells and their putative mechanisms of action have been investigated. Of the studied platinum(II) complexes, two ([Pt(glut)(dbtp)2] and [Pt(CBDC)(dbtp)2]) overcame the cisplatin resistance in human ovarian tumor cells (A2780cis or OVCAR-3) and arrested the cell cycle at S phase in mice mammary gland cancer cells (4T1), which indicates a mechanism of action different from that of cisplatin. Interestingly, preliminary in vivo toxicity assays revealed that both compounds tested in mice ([Pt(glut)(dbtp)2] 3 and [Pt(CBDC)(dbtp)2] 6) were less toxic in vivo than cisplatin or oxaliplatin. Additionally, compound 6 did not cause myelosuppression and showed over fivefold less accumulation in the liver than its glutarato analog 3.

Abstract
The platinum(II) oxalato complexes [Pt(ox)(naza)2] (1-3) were synthesized and characterized by elemental analysis (C, H, N), multinuclear NMR spectroscopy ((1)H, (13)C, (15)N, (195)Pt) and electrospray ionization mass spectrometry (ESI-MS); naza = 4-chloro-7-azaindole (4Claza; 1), 3-bromo-7-azaindole (3Braza; 2) or 4-bromo-7-azaindole (4Braza; 3). The prepared substances were screened for their in vitro antitumor activity on the osteosarcoma (HOS) and breast adenocarcinoma (MCF7) human cancer cell lines, where 2 showed moderate antitumor effect (IC50 = 27.5 μM, and 18.3 μM, respectively). The complex 2 was further tested on a panel of six others human cancer cell lines, including the malignant melanoma (G361), cervix carcinoma (HeLa), ovarian carcinoma (A2780), cisplatin-resistant ovarian carcinoma (A2780R), lung carcinoma (A549) and prostate adenocarcinoma (LNCaP). This substance was found to be moderate antitumor effective against G361 (IC50 = 17.3 μM), HeLa (IC50 = 31.8 μM) and A2780 (IC50 = 19.2 μM) cell lines. The complex 2 was also studied by NMR for its solution stability and by ESI-MS experiments for its ability to interact with biomolecules, such as cysteine, glutathione or guanosine 5'-monophosphate.

Abstract
A one-step synthetic procedure using the reaction of potassium bis(oxalato)platinate(II) with the corresponding N6-benzyladenosine derivative (nL) provided the [Pt(ox)(nL)₂]∙1.5H₂O oxalato (ox) complexes 1-5, involving the nL molecules as monodentate coordinated N-donor ligands. The complexes were thoroughly characterized by elemental analysis, multinuclear (¹H, ¹³C, ¹⁵N, 1¹⁹⁵Pt) and two dimensional NMR, infrared and Raman spectroscopy, and mass spectrometry, proving their composition and purity as well as coordination of nL through the N7 atom of the purine moiety. Geometry of [Pt(ox)(4FL)₂] (5) was optimized at the B3LYP/LANLTZ/6-311G** level of theory. The complexes were screened for their in vitro cytotoxicity against two human cancer cell lines (HOS osteosarcoma and MCF7 breast adenocarcinoma), but they did not show any effect up to the concentration of 50.0 µM (compounds 1, 2) or 20.0 µM (compounds 3-5).

Abstract
In the course of efforts to develop 17β-estradiol-linked to anticancer agents targeting estrogen-dependent tissue, we identified three estradiol-linked platinum(II) complex analogs to cisplatin (E-CDDP) derivatives namely: VP-128 (1), CD-38 (2) and JMP-39 (3) that exhibit potent in vitro and in vivo (for derivative VP-128) activity along with interaction with the estrogen receptor α (ERα). In this study, we prepared and biologically evaluated two novel classes of estradiol-linked platinum(II) complex analogs to carboplatin (E-CarboP, 1a-3a) and oxaliplatin (E-OxaP, 1b-3b). E-CarboP and E-OxaP were designed and based on the estradiol-linker scaffold of E-CDDP derivatives previously identified. Consequently, we assessed the importance of the nature of platinum(II) salt on the antiproliferative activity on MCF-7 and MDA-MB-231 human mammary carcinoma cell lines together with affinity for the ERα by replacing the dichloroplatinum(II) moiety by a cyclobutane-1,1-dicarboxylateplatinum(II) or an oxalateplatinum(II) moiety. Except for compound 3b which is inactive at the concentration tested, the antiproliferative activity of all compounds on both human mammary carcinomas cell lines are in micromolar range and are more active than carboplatin and oxaliplatin alone but less active that their E-CDDP counterparts (1-3). In addition, E-CarboP derivatives 1a-3a show very low affinity for ERα whereas E-OxaPs 1b and 2b show higher affinity for ERα than their parents E-CDDPs (1-2), suggesting that the nature of the platinum(II) salt involved in the vector complexes is extremely important to both retain significant antiproliferative activity and selectivity for the ERα and possibility to target estrogen-dependent tissues. Finally, E-OxaPs 1b and 2b are potentially promising alternatives vector complexes to target estrogen-dependent tissues.

Abstract
A series of seven platinum(II) cyclobutane-1,1-dicarboxylato (cbdc) complexes {[Pt(cbdc)(L(n))(2)], 1-7}, derived from carboplatin by a substitution of two NH(3) molecules for two 2,6,9-trisubstituted 6-benzylaminopurine-based N-donor ligands (L(n)), was studied by the MTT assay for their in vitro cytotoxic activity against seven human cancer cell lines, i.e. lung carcinoma (A549), cervix epithelioid carcinoma (HeLa), osteosarcoma (HOS), malignant melanoma (G361), breast adenocarcinoma (MCF7), ovarian carcinoma (A2780) and its cisplatin-resistant analogue (A2780cis), and against two primary cultures of human hepatocytes (LH31 and LH32). The prepared complexes were cytotoxic against several cancer cells, in some cases even more than cisplatin. The best results were achieved for complexes 1 (IC(50)=17.4 ± 2.0 μM) and 2 (IC(50)=14.8 ± 2.1 μΜ) against HOS cells, 1 (IC(50)=15.1 ± 6.8 μM), 2 (IC(50)=13.6 ± 5.2 μM) and 6 (IC(50)=19.0 ± 6.6 μM) against MCF7, 6 (IC(50)=6.4 ± 0.1 μM) against A2780, and 1-6 (IC(50)=15.6 ± 4.0, 12.9 ± 3.7, 15.8 ± 3.8, 16.6 ± 5.5, 22.1 ± 2.5, and 5.6 ± 1.7 μM, respectively) against A2780cis. Viability of human hepatocytes was not declined by the tested complexes up to the concentration of 50 μM (for 1, 3-7) and 20 μM (for 2; caused by lower solubility of this complex).

Abstract
The reactions of potassium bis(oxalato)platinate dihydrate with two molar equivalents of the potent adenine-based cyclin-dependent kinase inhibitor 2-(1-ethyl-2-hydroxyethylamino)-N6-(benzyl)-9-isopropyladenine (Roscovitine; Ros) and its benzyl-substituted analogues, i.e. 2-(1-ethyl-2-hydroxyethylamino)-N6-(2-methoxybenzyl)-9-isopropyladenine (2OMeRos), 2-(1-ethyl-2-hydroxyethylamino)-N6-(3-methoxybenzyl)-9-isopropyladenine (3OMeRos) and 2-(1-ethyl-2-hydroxyethylamino)-N6-(4-methoxybenzyl)-9-isopropyladenine (4OMeRos), were performed and the [Pt(ox)(Ros)(2)].(3/4)H(2)O (1), [Pt(ox)(2OMeRos)(2)].H(2)O (2), [Pt(ox)(3OMeRos)(2)].(1/2)H(2)O (3) and [Pt(ox)(4OMeRos)(2)].(3/4)H(2)O (4) platinum(II) oxalato complexes were obtained. The methods of the elemental analysis, IR, Raman and NMR spectroscopy, ESI + mass spectrometry, molar conductivity measurement and TG/DTA thermal analysis were performed to characterize the obtained products. The complexes 1-4 involve tetracoordinated central Pt(II) atom with one bidentate-coordinated oxalate dianion (ox) and two monodentate adenine-based molecules (nRos), thus giving the square-planar geometry around the metal centre with a PtN(2)O(2) donor set. In vitro cytotoxic activity of the complexes against ovarian carcinoma (A2780), cisplatin resistant ovarian carcinoma (A2780cis), malignant melanoma (G-361), lung carcinoma (A549), cervix epitheloid carcinoma (HeLa), breast adenocarcinoma (MCF7) and osteosarcoma (HOS) human cancer cell lines was evaluated. All the tested complexes exceeded the in vitro cytotoxicity of cisplatin and oxaliplatin against HeLa, A2780cis and, except for 2, also against HOS cancer cells. The complex 1 was also tested for its cytotoxicity in primary cultures of human hepatocytes and it was not found to be hepatotoxic up to the concentration of 50.0 microM.
