Half-Sandwich Nickelacarboranes Derived from [7-(MeO(CH2)2S)-7,8-C2B9H11]−

Half-sandwich iridium N-heterocyclic carbene anticancer complexes.

Half-sandwich pseudo-octahedral pentamethylcyclopentadienyl IrIII complexes of the type [(η5-Cpx)Ir(C^C)Cl]PF6, where Cpx is pentamethylcyclopentadienyl (Cp*), or its phenyl (Cpxph = C5Me4C6H5) or biphenyl (Cpxbiph = C5Me4C6H4C6H5) derivatives, and the C^C-chelating ligands are different N-heterocyclic carbene (NHC) ligands, have been synthesized and characterized. Three X-ray crystal structure...

New half sandwich Ru(II) coordination compounds for anticancer activity.

With the aim of expanding the structure-activity relationship investigation, the series of Ru(II) half sandwich coordination compounds of the type [Ru([9]aneS3)(chel)(L)](n+) previously described by us (where [9]aneS3 is the neutral face-capping ligand 1,4,7-trithiacyclononane, chel is a neutral or anonic chelating ligand, L = Cl(-) or dmso-S, n = 0-2) was extended to 1,4,7-triazacyclononane ([...

Major Anthraquinones Derived from Polygoni Multiflori Radix Alter Bile Acid Disposition in Sandwich Cultured Rat Hepatocytes

Terpenoids from the Marine-Derived Fungus Aspergillus fumigatus YK-7.

Two new β-bergamotane sesquiterpenoids, E-β-trans-5,8,11-trihydroxybergamot-9-ene (1) and β-trans-2β,5,15-trihydroxybergamot-10-ene (2), were isolated from the marine-derived fungus Aspergillus fumigatus YK-7, along with three known terpenoids 3-5. Their structures were determined by spectroscopic methods (1D and 2D NMR, HR-ESI-MS). Antiproliferative effects on human leukemic monocyte lymphoma ...

Self-assembled half-sandwich Ir, Rh-based organometallic molecular boxes for reversible trapping of halocarbon molecules.

Reactions of [Cp*MCl(mu-Cl)](2) (M = Ir or Rh) with 6,11-dihydroxy-5,12-naphthacenedione (H(2)DHNA) in the presence of base, gave the corresponding binuclear complexes [Cp*(2)M(2)(mu-DHNA)Cl(2)] (M = Ir (1a); M = Rh (1b)), respectively. Treatment of 1a or 1b with bidentate ligands (L) such as pyrazine, 4,4'-dipyridine (bpy), E-1,2-bis(4-pyridyl)ethene (bpe) or 2,5-bis(4-pyridyl)-1,3,5-oxadiazol...
