Two hexanuclear rhenium clusters containing azide ligands, [Re6Se8(PEt3)5(N3)]BF4 and [Re6Se8(PEt3)4(N3)2], were synthesized from the analogous pyridine complexes and fully characterized. Studies show that [Re6Se8(PEt3)5(N3)]BF4 reacts with activated alkynes, dimethyl acetylenedicarboxylate and methyl 4-hydroxyhex-2-yneoate, to form the triazolate cluster complexes [Re6Se8(PEt3)5(L1 or L2)]BF4 ...

Hexamethylene bisacetamide, a compound which in vitro induces differentiation in a wide variety of human and animal cancer cell lines, is being investigated in phase I clinical trials. After i.v. administration of hexamethylene bisacetamide to humans, urine contained the parent compound and at least five metabolites formed by deacetylation and oxidation pathways. Identification of urinary metab...

A series of inhibitors of the soluble epoxide hydrolase (sEH) containing two urea groups has been developed. Inhibition potency of the described compounds ranges from 2.0 μM to 0.4 nM. 1,6-(Hexamethylene)bis[(adamant-1-yl)urea] (3b) was found to be a potent slow tight binding inhibitor (IC50=0.5 nM) with a strong binding to sEH (Ki=3.1 nM) and a moderately long residence time on the enzyme (kof...

The structures of a series of complexes with general formula n[Pd(pza)X]Y·mH2O (n = 1, 2; X = Cl, Br, I, N3, NCS; Y = NO3, I, N3, [Pd(SCN)4]; m = 0, 0.5, 1) have been determined, where pza is the tridentate ligand bis-[2-(3,5-di-methyl-pyrazol-1-yl)eth-yl]amine, C14H23N5. In all complexes, {bis-[2-(3,5-di-methyl-pyrazol-1-yl-κN (2))eth-yl]amine-κN}chlorido-palladium nitrate, [Pd(pza)Cl]NO3, (1)...
