Annotation:

The dipyrrin–metal complexes and especially the boron complex 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) have recently attracted considerable attention because of their interesting properties and possible applications. We have developed two unique and useful ways to extend versatility and usefulness of the dipyrrin complexes. The first one is the linear and macrocyclic oligomerization of the BODIPY units. These arrangements of the B–F moieties of the oligomerized BODIPY units provide sophisticated functions, such as unique recognition ability toward cationic guest, associated with changes in the photophysical properties by utilizing unprecedented interactions between the B–F and a cationic species. The second one is introduction of additional ligating moieties into the dipyrrin skeleton. The multidentate N2Ox dipyrrin ligands thus obtained form a variety of complexes with 13 and 14 group elements, which are difficult to synthesize using the original N2 dipyrrin derivatives. Interestingly, these unique complexes exhibit novel structures, properties, and functions such as guest recognition, stimuli-responsive structural conversion, switching of the optical properties, excellent stability of the neutral radicals, etc. We believe that these multifunctional dipyrrin complexes will advance the basic chemistry of the dipyrrin complexes and develop their applications in the materials and medicinal chemistry fields.1 Introduction2 Linear Oligomers of Boron–Dipyrrin Complexes3 Cyclic Oligomers of Boron–Dipyrrin Complexes4 A Cyclic Oligomer of Zinc–Dipyrrin Complexes5 Group 13 Element Complexes of N2Ox Dipyrrins6 Chiral N2 and N2Ox Dipyrrin Complexes7 Group 14 Element Complexes of N2O2 Dipyrrins8 Other N2O2 Dipyrrin Complexes with Unique Properties and Functions9 Conclusion

Annotation:

A new series of metal complexes with 1-(2-methylphenyl)-4,4,6-trimethyl pyrimidine-2-thione (2-HL1) and 1-(4-methylphenyl)-4,4,6-trimethyl pyrimidine-2-thione (4-HL2) ligands, [M(mppt)2(H2O)n] (M(II) = Cu, Mn, Co; n = 2 and M(II) = Ni, Zn; n = 0) have been synthesized using mechanochemical protocol. The complexes have been framed as [M(mppt)2(H2O)n] due to 1:2 (metal:ligand) nature of these metal complexs. Structures have been further confirmed on the basis of elemental analysis, Magnetic susceptibility measurements, electronic, infrared, far infrared, proton NMR, Mass spectral moment and thermogravimetric analysis studies. The infrared spectral data suggested that ligand behaves as a bidentate, coordinating through – N (endocyclic) and – S (exocyclic) donor atoms. All the compounds have also been screened for antibacterial and DNA photocleavage potential. Ligands complexed with Mn and Ni metals have shown the effect of substitution on their biological potentials. It was found that substitution at 4th or para position makes the ligand and its metal complexes have better antibacterial and DNA photocleaving agents.

Annotation:

Metal complexes are the effective therapeutic compound and it became more emerging field in the drug discovery and delivery. A novel ligand phenyl-glycine -o- carboxylic acid was synthesized and further complexed with the metal (II) chlorides. The synthesized metal complexes was interpreted by FT-IR spectroscopy, Ultra Violet- visible, 1H-NMR, molar conductance, magnetic susceptibility and thermogravimetric study. The electrochemical properties of the ligand and its complexes were inquired in DMF. Antibacterial and fungal activities of the phenyl-glycine -o- carboxylic acid (ligand) and metal complexes were analyzed by three fungal and four bacteria pathogens. The ligand has no activity against Aspergillus terreus, but nickel, copper and cobalt chloride complexes showed good activity against Aspergillus terreus. On anti-bacterial activity compare to ligands and other metal (II) complexes the cobalt (II) complex revealed greater inhibition effect on selected bacteria.

Annotation:

The importance of essential metal ions and their metal complexes in the creation of prospective medical therapies has long been recognized. In chemistry, molecular biology, and medicinal fields; the interaction of metal complexes with DNA has been a subject of study. The dithiocarbamate essential metal complex is described extensively in the literature for its various benefits and advantages. With proper use of ligands, it is proven to increase the cytotoxic activity of metal complexes against cancer cells. Some researches have shown significant progress regarding the biological activities of the dithiocarbamate essential metal complex as antimicrobial, antioxidant, and anticancer agents. Metal complexes form complexes with dithiocarbamate ligands with unique structural variations. In this study, we presented an overview of the cytotoxic effects of some dithiocarbamate essential metal complexes on cancer cells, as well as fresh approaches to the design of essential metal-based therapeutics containing dithiocarbamate and molecular targets in cancer therapy. This review may provide an update on recent developments in the medicinal use of essential metals with dithiocarbamate ligands, carried out to identify recent relevant literature. Finally, we predict that the essential metal complexed with dithiocarbamate can be a new breakthrough in the future development of cancer drugs.

Annotation:

New series of three bidentate N, O donor type Schiff bases(L1)–(L3)were prepared by using ethylene-1,2-diamine with 5-methyl furfural, 2-anisaldehyde, and 2-hydroxybenzaldehyde in an equimolar ratio. These ligands were further complexed with Co(II), Cu(II), Ni(II), and Zn(II) metals to produce their new metal complexes having an octahedral geometry. These compounds were characterized on the basis of their physical, spectral, and analytical data. Elemental analysis and spectral data of the uncomplexed ligands and their metal(II) complexes were found to be in good agreement with their structures, indicating high purity of all the compounds. All ligands and their metal complexes were screened for antimicrobial activity. The results of antimicrobial activity indicated that metal complexes have significantly higher activity than corresponding ligands. This higher activity might be due to chelation process which reduces the polarity of metal ion by coordinating with ligands.

Annotation:

The initial events (virus adsorption and fusion with the cells) in the replicative cycle of human immunodeficiency virus (HIV) can serve as targets for the antiviral action of metal-binding compounds such as polyanionic compounds (polysulfates, polysulfonates, polycarboxylates, polyoxometalates, and sulfonated or carboxylated metalloporphyrins), bicyclams and G-octet-forming oligonucleotides. The adsorption and fusion of HIV with its target cells depends on the interaction of the viral envelope glycoproteins (gp 120) with the receptors (CD4, CXCR4) at the outer cell membrane. We are currently investigating how the aforementioned compounds interfere with these viral glycoproteins and/or cell receptor.

Annotation:

New polysilane-metal complexes structures were obtained by the polycondensation reaction of α,ω-bis(chloromethyl)-polymethylphenylsilane with the Ni (II) complex of bis(salicylidene)ethylenedia-mine (salen). The chloro-functionalized polysilane was obtained by a modified Wurtz coupling procedure at low temperatures. To obtain the polymer-metal complex the resulted macroligand was complexed with metal cations. This structure is characterized by a highly localized electroactivitry in the redox moiety combined with a specific σ conjugative effect in the polysilane chain. Infrared, 1H NMR and UV-vis spectral analysis as well as gel permeation chromatography and thermogravimetric analysis were used to investigate the new chemical structures.

Annotation:

Schiff base derived from the reaction of 2-amino phenol and 2-hydroxy-1-naphthaldehyde and its Co (II), and Mn (II) complexes have been synthesized and characterized by solubility test, melting point/ decomposition temperatures, molar conductance, IR and magnetic susceptibility. The number of ligands coordinated to the metal ion was determined using Job’s method of continuous variation. Their molar conductance values indicate that all the complexes are non-electrolytes. Magnetic moment values of the complexes showed that both Mn (II) and Co (II) are paramagnetic. The spectroscopic data of metal complexes indicated that the metal ions are complexed with azomethine nitrogen and deprotonated oxygen atom. Corrosion inhibition of the schiff base and Mn (II) and Co (II) complexes were evaluated using the weight loss method in a 0.1MHCl solution for copper metal. The inhibition efficiency increased with increasing inhibitors concentration. The negative values of Gibb’s free energy of adsorption (ΔGads) confirmed the spontaneity and physical adsorption of the inhibition process which is inconsistent with Langmuir adsorption isotherm.

A new Schiff base ligand 2-((2-furylmethylene)amino)benzenethiol of the type ONS has been synthesized from 2- aminothiophenol and 2-furfuraldehyde and complexed with Co(II), Ni(II) and Cu(II) metal ions. The synthesized ligand and complexes [Co(II),Ni(II) 8Cu(II)] were characterized using various spectral techniques viz., IR, NMR, EI-MS and thermogravimetric analysis. The geometry of the synthesized complexes was confirmed by electronic spectra, magnetic moment measurements and EPR analysis. DNA cleavage studies were performed using Gel electrophoresis method. The antibacterial activity of all the metal complexes studied against Gram positive bacterial strains Bacillus substilis, Staphylococcus aureus, and also Gram negative bacteria Escherichia coli, Pseudomonas fluorescens and Klebsiella pneumoniae with comparison to Gentamycin. Antifungal activities were carried out against two fungal strains i.e. Aspergillus Niger and Candida albicans. Schiff base and its metal complexes were also screened for in vitro antioxidant activity and was observed that the Co(II) complex shows enhanced activity when compared to ligand and other metal complexes and was further substantiated by molecular docking studies.

This study focuses characterization of iron (II), iron (III), cobalt (II), copper (II) and nickel (II) complexes of Isoniazid (INH) and studying their spectroscopic as well as physiochemical properties. FTIR studies showed that INH binds the metal from oxygen of carbonyl group and nitrogen of amino group. The proton NMR spectra of the metal complexes confirmed the conversion of ligand molecules into their respective metal complexes. However, pattern of splitting and shapes of peaks was observed but the protons resonated in the expected region. XRD patterns may be concluded that the complexes are mostly comprised of nano-sized particles behaving like amorphous materials. Scanning electron microscopy (SEM) revealed marked changes in the morphology of complexes, and their degradation at higher temperature strengthens the hypothesis of the successful formation of complexes. The MTT cytotoxicity assay was used for the screening these complexes against four human cell lines but the results did not prove significant.

Annotation:

Of all properties of metal nucleobase complexes, formation of multinuclear species appears to be an outstanding feature. After a brief introduction into well known polymeric metal nucleobase complexes, three aspects recently Studied in our laboratory will be dealt with in more detail: (i) Heteronuclear complexes derived from trans-[(amine)2Pt(1-MeC)2]2+ (1-MeC=1-methylcytosine). They form, e. g. with Pd(II) or Hg(II), upon single deprotonation of the exocyclic amino group of each 1-MeC ligand, compounds of type trans-[(amine)2Pt(1-MeC-)2MY]n+, displaying Pt-M bond formation. (ii) Cyclic nucleobase complexes derived from cis-a2Pt(II). A cyclic compound of composition {[(en)Pt(UH-N1,N3)]4}4+ (UH=monoanion of unsubstituted uracil) is presented and the analogy with organic calix-[4]-arenes is pointed out. (iii) Cyclic nucleobase complexes from trans-a2Pt(II). Possible ways for the preparation of macrocyclic nucleobase complexes containing trans-a2Pt(II) linkages are outlined and precursors and intermediates are presented.

The condensation reaction between dimethyl tetraphthalate and hydrazine hydrate results in the formation of 4-formylbenzohydrazide, which was refluxed with malonic acid to obtain novel hydrazone ligand (FBH-L). The ligand was further subjected to coordinate with two metal salts viz. ZrCl4 and NiCl2 to synthesize respective transition metal(II) complexes. The ligand and its metal complexes were characterized by various spectral and analytical techniques like UV, FTIR, 1H NMR, 13C NMR, mass spectrometry, etc. The synthesized complexe were evaluated for their antibacterial and anti-angiogenic properties to determine their impact on microorganisms and the growth of blood cells, respectively and the results obtained were found to be satisfactory. Furthermore, all the metal-complexes demonstrated its efficacy as photocatalyst and also ability to remove metals from real water samples.

Annotation:

Metal induced stabilization of α-carbocations is well known for cobalt- and molybdenum complexed propargyl cations. The same principle also allows access to reactivity enhancement of metal coordinated halo- and hydrosilylalkynes. In a previous study, we have shown that coordination of oligosilanylalkynes to the dicobalthexacarbonyl fragment induces striking reactivity to the oligosilanyl part. The current paper extends this set of oligosilanylalkyne complexes to a number of new dicobalthexacarbonyl complexes but also to 1,2-bis(cyclopentadienyl)tetracarbonyldimolybdenum and (dippe)Ni complexes. NMR-Spectroscopic and crystallographic analysis of the obtained complexes clearly show that the dimetallic cobalt and molybdenum complexes cause rehybridization of the alkyne carbon atoms to sp3, while in the nickel complexes one π-bond of the alkyne is retained. For the dicobalt and dimolybdenum complexes, strongly deshielded 29Si NMR resonances of the attached silicon atoms indicate enhanced reactivity, whereas the 29Si NMR shifts of the respective nickel complexes are similar to that of respective vinylsilanes.

Annotation:

Medicinal applications of metals and their complexes are of elevating clinical importance especially during COVID-19 pandemic. Antibiotics like (Ceftriaxone "CFx"– Erythromycin"Ery") chemically complexes with different metals by using methanol and continuous stirring for 3 h and then the colored precipitates were obtained and then dried for further chemical analysis and confirming the chemical structure by TEM analysis and then measuring total antioxidant capacity of the complex and performing DPPH assay for the antibiotic drug and its different metal complexes like Se (II) , Mg(II) and Zn (II). complexes were studied and characterized based on transmission electron microscopy (TEM). Chemical data revealed that CFx and Ery have great ability to complexes with these metals and give different chemical structure. Antioxidant capacities , anti-inflammatory activities were carried out in vitro. The metal complexed with antibiotics "combination" exhibited potent antioxidant and ant inflammatory activities and suppressed oxidative stress that could adjust the pulmonary disturbances and alterations induced by pneumenia. In conclusion, Antibiotics/metal drug complexes could produce a high synergistic effects against oxidative stress and viral infection symptoms in some cases and can be considered potential ameliorative therapy against pulmonary dysfunction, which may benefit against COVID-19 pandemic.
