Binuclear dioxomolybdenum(VI) complexes of some tridentate ONS donor ligand containing [MoO2]2+ as the acceptor center: Synthesis, crystal structure, supramolecular architectures via hydrogen bonds, π-π Stacking and DFT calculations

A series of linear diimine and diamine-bridged binuclear dioxomolybdenum(VI) complexes having general formula [(MoO2L)2(B-B)] [where, B-B is a bridging linear N,N′-bidentate spacer 4,4′ bipyridine, 1,2 bis (4-pyridyl) ethene and 1,2

Synthesis, characterization, X-ray crystallography, and antimicrobial activities of Ni(II) and Cu(II) complexes with a salicylaldehyde-based thiosemicarbazone ligand

A new salicylaldehyde-based ONS tridentate salicylaldehyde-N(4)- diethylthiosemicarbazone (H2SANEt2) has been synthesized and characterized by elemental analyses mass, IR, and 1H NMR spectral parameters. The coordination m

Methyl-2-arylidene hydrazinecarbodithioates: Synthesis and biological activity

Methyl-2-arylidene hydrazine-carbodithioate has not been of particular interest to researchers even though its metal complexes are extensively reported on due to their biological activity. This study examined the cytostatic and antiviral activity of twelve methyl-2-arylidene hydrazinecarbodithioates reported by many researchers as intermediates for the synthesis of thiosemicarbazides and the preparation of their metal complexes. Compounds IIc, IIi, and IIl with tridentate ligand features were found to have the lowest IC50 value (6.5 μM, ≈ 1 μM, and 0.8 μM, respectively) against HL60 human promyelocytic leukemia cells. They were also most inhibitory to human embryonic lung (HEL) fibroblast proliferation (5.3 μM, 17 μM, and 2.6 μM). Compound IIc and IIl show antiviral activity against wild-type herpes simplex virus (HSV), varicella zoster virus (VZV), and acyclovirresistant HSV; however, these activities were observed at concentrations at which the compounds also markedly inhibit HL60 and HEL cell proliferation.

Synthesis, antimicrobial and anticancer activity of new thiosemicarbazone derivatives

Thiosemicarbazones of p-aminobenzoic acid (PABA) were synthesized and tested for their antimicrobial and anticancer activity. Hydroxamate derivatives 4a-4l were found to have better antimicrobial and anticancer activity than their acid counterpart. Compound 4d was found to have good antimicrobial activity against Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Vibrio cholerae, and Bacillus subtilis with IC50 value of about 1 aμM. Compound 4f showed potent antifungal activity against Candida albicans (IC50a=a1.29 aμM) and compound 4h showed potent anticancer activity (IC50a=a0.07 aμM). Hydroxamate derivatives 4a-4l were found to show better antimicrobial and anticancer activity in compariosn with their acid counterparts 3a-3l. Copyright

Design, synthesis and anticancer activity of piperazine hydroxamates and their histone deacetylase (HDAC) inhibitory activity

Six compounds were synthesized with piperazine in linker region and hydroxamate as Zinc Binding Group (ZBG). They were screened against three cancer cell-lines (NCIH460; HCT116; U251). Compounds 5c and 5f with GI50 value of 9.33 ± 1.3 μM and 12.03 ± 4 μM, respectively, were tested for their inhibitory potential on hHDAC8. Compound 5c had IC50 of 33.67 μM. Compounds were also screened for their anticancer activity against HL60 human promyelocytic leukemia cell line due to the presence of pharmacophoric features of RR inhibitors in them. Compound 5c had IC 50 of 0.6 μM at 48 h.

Synthesis and characterization of oxothiomolybdenum(VI) complexes of some ONS chelating ligands by in situ oxo removal and sulphido insertion in the corresponding dioxomolybdenum(VI) complexes

This work reports the synthesis, characterization and electrochemical studies of several [MoVIOS]2+ complexes of some tridentate ONS donor ligands obtained by the condensation of salicylaldehyde/2- hydroxyacetophenone with S-benzyl and S-methyl dithiocarbazates. In this work PPh3 and PPh3S mixture is used as the synthetic reagent. The general strategy of synthesizing the complexes of the [MoOSL] type with the [MoOS]2+ core from corresponding complexes with the [MoO 2]2+ core by in situ oxoremoval-sulphide addition process. Presence of the oxothio core in all the [MoOSL] complexes is established by their reaction with KCN resulting in the formation of the CNS- species. All the complexes are characterized by various spectroscopic (NMR, IR, UV-Vis) techniques and also by cyclic voltammetry. All the complexes exhibit an irreversible overall 2 electron reductive response probably by proton assisted loss of the sulphide group leading to the formation of the corresponding [MoOL] complex.

Synthesis and Ribonucleotide reductase inhibitory activity of thiosemicarbazones

Ribonucleotide reductase (RR) is an important therapeutic target for anticancer drugs. The structure of human RR features a 1:1 complex of two homodimeric subunits, hRRM1 and hRRM2. Prokaryotically expressed and highly purified recombinant human RR subunits, hRRM1 and hRRM2, were used for holoenzyme-based [3H]CDP reduction in vitro assay. Ten new thiosemicarbazones (7-16) were synthesized and screened for their RR inhibitory activity. Two thiosemicarbazones derived from p-hydroxy benzaldehyde (9 and 10) were found to be active but less potent than the standard, Hydroxyurea (HU). Guided by the activity of compounds 9 and 10, 11 new thiosemicarbazones (17-27) derived from p-hydroxy benzaldehyde were prepared and screened for their RR inhibitory activity. All the 11 compounds were more potent than HU.
