Abstract
In the current portfolio, there is a lot of interest in the 7-azaindole building block for drug discovery. The creation of synthetic, sophisticated methods for the modification of 7-azaindoles is a promising area of research. This review covers the structure-activity relationship of 7-azaindole analogs, which have been shown to be effective anticancer agents in the literature of the past two decades. Positions 1, 3 and 5 of the 7-azaindole ring are the most active sites. Disubstitution is used for the synthesis of a new analog of the 7-azaindole moiety. All positions are used to create novel molecules that are effective anticancer agents. The alkyl, aryl carboxamide group and heterocyclic ring are the most successful types of substitution.

Abstract
C-C reductive elimination from [PdL2(C6F5)2] to form polyfluorinated biaryls has been a challenge for over 50 years. Thus, palladium-catalyzed homocoupling of arylboronates (ArF-Bpin) containing two ortho-fluorine substituents is very difficult, as the reaction typically stops at the [PdL2(ArF)2] stage after two transmetalation steps. The transmetalated complexes cis-[Pd(MeCN)2(C6F5)2] (3a), cis-[Pd(MeCN)2(2,4,6-C6F3H2)2] (3b), and cis-[Pd(MeCN)2(2,6-C6F2H3)2] (3e) have been isolated from the reaction of ArF-Bpin with Pd(OAc)2 in acetonitrile solvent, with no homocoupling observed. However, catalytic homocoupling proceeds smoothly in a "weakly coordinating" arene solvent as long as no ancillary ligands or coordinating solvents are present. DFT computations reveal that the active catalyst formed by arene solvent coordination leads to an overall reduced barrier for the reductive elimination step compared to the formation of stable [PdL2(ArF)2] complexes in the presence of a donor ligand or solvent L.

Abstract
This report demonstrates that changing the position of the carbon-metal bond in a polypyridyl cyclopalladated complex, i.e. going from PdL1 (N^N^C^N) to PdL2 (N^N^N^C), dramatically influences the photodynamic properties of the complex in cancer cells.

Abstract
Homoleptic complexes of the anion of 7-azaindole (AzaIn) were synthesized and characterized for a series of 3d transition metals. For Mn(II), Fe(II), and Co(II), complexes of formula Na2[M(AzaIn)4]·2L (L = tetrahydrofuran (THF), 2-MeTHF, toluene, or benzene) were isolated by treatment of the corresponding metal chloride salts with 7-azaindole in the presence of sodium hexamethyldisilazide. The complexes adopt tetrahedral geometries with exclusive coordination to the transition metal ion through the pyrrolic N1 nitrogen atoms of the AzaIn ligands. Solid-state structures of the complexes demonstrate that the sodium cations remain tightly associated with the coordination entities through interaction with both the pyrrolic and pyridine nitrogen atoms of the azaindolide ligands. For Fe(II), replacement of the sodium cations by other alkali metal ions (Li or K) generates new complexes that demonstrate similar coordination geometries to the sodium salts. As a means of comparison, the Fe(II) complex of 4-azaindolide was also investigated. Na2[Fe(4-AzaIn)4]·2L adopts a similar solution structure to the 7-azaindolide complexes as judged by NMR spectroscopy and cyclic voltammetry. Density functional theory calculations were performed to investigate the bonding in the 7-azaindolide complexes. Results demonstrate that 7-azaindolide-κ(1)-N1 is a nearly pure sigma donor ligand that features a high degree of ionic character in its bonding to mid 3d transition metal ions.

Abstract
A series of novel C,N-cyclometalated benzimidazole ruthenium(II) and iridium(III) complexes of the types [(η(6)-p-cymene)RuCl(κ(2)-N,C-L)] and [(η(5)-C5Me5)IrCl(κ(2)-N,C-L)] (HL = methyl 1-butyl-2-arylbenzimidazolecarboxylate) with varying substituents (H, Me, F, CF3, MeO, NO2, and Ph) in the R4 position of the phenyl ring of 2-phenylbenzimidazole chelating ligand of the ruthenium (3a-g) and iridium complexes (4a-g) have been prepared. The cytotoxic activity of the new ruthenium(II) and iridium(III) compounds has been evaluated in a panel of cell lines (A2780, A2780cisR, A427, 5637, LCLC, SISO, and HT29) in order to investigate structure-activity relationships. Phenyl substitution at the R4 position shows increased potency in both Ru and Ir complexes (3g and 4g, respectively) as compared to their parent compounds (3a and 4a) in all cell lines. In general, ruthenium complexes are more active than the corresponding iridium complexes. The new ruthenium and iridium compounds increased caspase-3 activity in A2780 cells, as shown for 3a,d and 4a,d. Compound 4g is able to increase the production of ROS in A2780 cells. Furthermore, all the new compounds are able to overcome the cisplatin resistance in A2780cisR cells. In addition, some of the metal complexes effectively inhibit angiogenesis in the human umbilical vein endothelial cell line EA.hy926 at 0.5 μM, the ruthenium derivatives 3g (Ph) and 3d (CF3) being the best performers. QC calculations performed on some ruthenium model complexes showed only moderate or slight electron depletion at the phenyl ring of the C,N-cyclometalated ligand and the chlorine atom on increasing the electron withdrawing effect of the R substituent.

Abstract
The reactivity of the [Pt(dmba)(aza-N1)(dmso)] complex 1, (a potential antitumoral drug with lower IC50 than cisplatin in several tumoral cell lines) with different proteins and oligonucleotides is investigated by means of mass spectrometry (ESI-TOF MS). The results obtained show a particular binding behaviour of this platinum(II) complex. The interaction of 1 with the assayed proteins apparently takes place by Pt-binding to the most accessible coordinating amino acids, presumably at the surface of the protein -this avoiding protein denaturation or degradation- with the subsequent release of one or two ligands of 1. The specific reactivity of 1 with distinct proteins allows to conclude that the substituted initial ligand (dmso or azaindolate) is indicative of the nature of the protein donor atom finally bound to the platinum(II) centre, i.e. N- or S-donor amino acid. Molecular modeling calculations suggest that the release of the azaindolate ligand is promoted by a proton transfer to the non-coordinating N present in the azaindolate ring, while the release of the dmso ligand is mainly favoured by the binding of a deprotonated Cys. The interaction of complex 1 with DNA takes always place through the release of the azaindolate ligand. Interestingly, the interaction of 1 with DNA only proceeds when the oligonucleotides are annealed forming a double strand. Complex 1 is also capable to displace ethidium bromide from DNA and it also weakly binds to DNA at the minor groove, as shown by Hoechst 33258 displacement experiments. Furthermore, complex 1 is also a good inhibitor of cathepsin B (an enzyme implicated in a number of cancer related events). Therefore, although compound 1 is definitely able to bind proteins that can hamper its arrival to the nuclear target, it should be taken into consideration as a putative anticancer drug due to its strong interaction with oligonucleotides and its effective inhibition of cat B.

Abstract
The in vitro antitumour activity studies on a panel of human cancer cell lines (A549, HeLa, G-361, A2780, and A2780R) and the combined in vivo and ex vivo antitumour testing on the L1210 lymphocytic leukaemia model were performed on the cis-[PtCl2(naza)2] complexes (1–3) involving the 7-azaindole derivatives (naza). The platinum(II) complexes showed significantly higher in vitro cytotoxic effects on cell-based models, as compared with cisplatin, and showed the ability to avoid the acquired resistance of the A2780R cell line to cisplatin. The in vivo testing of the complexes (applied at the same dose as cisplatin) revealed their positive effect on the reduction of cancerous tissues volume, even if it is lower than that of cisplatin, however, they also showed less serious adverse effects on the healthy tissues and the health status of the treated mice. The results of ex vivo assays revealed that the complexes 1–3 were able to modulate the levels of active forms of caspases 3 and 8, and the transcription factor p53, and thus activate the intrinsic (mitochondrial) pathway of apoptosis. The pharmacological observations were supported by both the histological and immunohistochemical evaluation of isolated cancerous tissues. The applicability of the prepared complexes and their fate in biological systems, characterized by the hydrolytic stability and the thermodynamic aspects of the interactions with cysteine, reduced glutathione, and human serum albumin were studied by the mass spectrometry and isothermal titration calorimetric experiments.

Abstract
A series of potent C,N-cycloplatinated(II) phosphine antitumor complexes containing fluorous substituents in the cyclometalated or the ancillary phosphine ligands [Pt(C-N)(PR3)Cl] or both have been synthesized and characterized. The crystal structure of [Pt(dmba){P(C6H4CF3-p)3}Cl]·2CH2Cl2 (dmba = dimethylaminomethyl)phenyl) has been established by X-ray diffraction. Values of IC50 of the new platinum complexes were calculated toward a panel of human tumor cell lines representative of ovarian (A2780 and A2780cisR) and breast cancers (T47D). Complexes containing P(C6H4CF3-p)3 as ancillary ligand (with a bulky and electronegative CF3 substituent in para position) were the most cytotoxic compounds in all the tested cancer cell lines. In some cases, the IC50 values were 16-fold smaller than that of cisplatin and 11-fold smaller than the non-fluorous analogue [Pt(dmba)(PPh3)Cl]. On the other hand, very low resistance factors (RF) in A2780cisR (cisplatin-resistant ovarian carcinoma) at 48 h were observed (RF ≈ 1) for most of the new compounds. Analysis of cell cycle was done for the three more active compounds in A2780. They arrest cell growth in G0/G1 phase in contrast to cisplatin (S phase) with a high incidence of late-stage apoptosis. They are also good cathepsin B inhibitors (an enzyme implicated in a number of cancer related events).

Abstract
Two new steroidal 7-azaindole-based N-donor ligands 17-α-[7-azaindole-5-ethynyl]-17-β-testosterone (ET-Haza) (1) and 17-α-[7-azaindole-5-ethynyl]-19-nortestosterone (LEV-Haza) (2), and two new DNA damaging warheads with an enhanced lipophilicity [Pt(dmba)Cl(L)] (dmba=N,N-dimethylbenzylamine-κN,κC; L=ET-Haza (3) and LEV-Haza (4)) have been prepared and characterized. Values of IC50 were calculated for complexes 3 and 4 against a panel of human tumor cell lines representative of ovarian (A2780 and A2780cis) and breast cancers (T47D). At 48 h of incubation time 3 and 4 showed very low resistance factors (RF of 1) against an A2780 cell line which has acquired resistance to cisplatin, IC50 values of the new complexes towards normal human LLC-PK1 renal cells at 48 h being about double than that of cisplatin. 3 and 4 are able to react with 9-ethylguanine (9-EtG) yielding the corresponding monoadduct [Pt(dmba)(L)(9-EtG)](+) derivatives as followed by ESI-MS. Compound 3 interacts mainly with double-stranded (DS) oligonucleotides as shown by analysis with ESI-TOF-MS, being also able to displace ethidium bromide (EB) from DNA, as observed by an electrophoretic mobility study. 3 and 4 are good cathepsin B inhibitors. Theoretical calculations at the COSMO(CHCl3)/B3LYP-D/def2-TZVPPecp//B3LYP-D/def2-TZVPecp level and energy evaluations at the COSMO(CHCl3)/PWPB95-D3/def2-TZVPPecp level of theory on compound 4 and model systems have been done.
