Do metal-metal multiply-bonded “ligands” have a trans influence? Structural and magnetic comparisons of heterometallic Cr=Cr…Co and Mo=Mo…Co interactions

Reported here are two new compounds containing either a Cr=Cr…Co [1, CrCrCo(dpa)4Cl2, dpa = 2,2?-dipyridylamide] or a Mo=Mo…Co [2, MoMoCo(dpa)4Cl2] framework both having a multiply-bonded unit (Cr=Cr in 1, Mo=Mo in 2) in close proximity to the Co2+ ion and trans to a Co-Cl bond. Variable temperature magnetic susceptibility measurements reveal 1 to have a temperature-dependent spin equilibrium between a low-spin (S = 1/2) and high-spin (S = 3/2) state, whereas the Co2+ ion in 2 exists solely in its high-spin state. The crystal structures of 1 and 2 were determined. Variable temperature crystallographic data of 1 at 100 K and at room temperature reveal that the spin-transition affects not only the Co-ligand bond lengths but also the terminal Cr-ligand bond lengths. Whereas the Cr…Co distance becomes shorter by 0.13 A in the low-spin form, the Co-Cl distance becomes longer by 0.2 A. These observations, along with the crystal structure of 2, suggest that the multiply-bonded M=M group has a trans influence on the Co2+ ion. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Controllable Synthesis of Lindqvist Alkoxopolyoxovanadate Clusters as Heterogeneous Catalysts for Sulfoxidation of Sulfides

In compounds 1-4 and 6, Cu or Co complexes and alkoxohexavanadate anions are assembled through electrostatic interactions. Differently, in compound 5, seven-methoxo-substituted Lindqvist-type [V6O12(OMe)7]2- are bridged to Cu complex via terminal O atoms by coordination bonds. All compounds 1-6 exhibit excellent heterogeneous catalytic performance in oxidative desulfurization and CEES ((2-chloroethyl) ethyl sulfide, a sulfur mustard simulant) abatement with H2O2 as oxidant. Among them, the catalytic activity of 6 [conv. of DBT (dibenzothiophene) up to 100% in 6 h; conv. of CEES reached 100% and selectivity of CEESO ((2-chloroethyl) ethyl sulfoxide) up to 85% after 4 h] outperforms others and can be reused without losing its activity.

3-oxoisoindoline-1-carboxamides: Potent, state-dependent blockers of voltage-gated sodium channel nav1.7 with efficacy in rat pain models

The voltage-gated sodium channel NaV1.7 is believed to be a critical mediator of pain sensation based on clinical genetic studies and pharmacological results. Clinical utility of nonselective sodium channel blockers is limited due to serious adverse drug effects. Here, we present the optimization, structure-activity relationships, and in vitro and in vivo characterization of a novel series of NaV1.7 inhibitors based on the oxoisoindoline core. Extensive studies with focus on optimization of Na V1.7 potency, selectivity over NaV1.5, and metabolic stability properties produced several interesting oxoisoindoline carboxamides (16A, 26B, 28, 51, 60, and 62) that were further characterized. The oxoisoindoline carboxamides interacted with the local anesthetics binding site. In spite of this, several compounds showed functional selectivity versus Na V1.5 of more than 100-fold. This appeared to be a combination of subtype and state-dependent selectivity. Compound 28 showed concentration- dependent inhibition of nerve injury-induced ectopic in an ex vivo DRG preparation from SNL rats. Compounds 16A and 26B demonstrated concentration-dependent efficacy in preclinical behavioral pain models. The oxoisoindoline carboxamides series described here may be valuable for further investigations for pain therapeutics.

Detection of metabolite changes in C6 glioma cells cultured with antimitotic oleyl glycoside by1H MAS NMR

The synthetic glycoside, oleyl N-acetyl-alpha-D-glucosaminide (1), was previously shown to exhibit antimitotic activity on rat (C6) and human (U-373) glioma lines. To obtain information about its mechanism of action, metabolite changes in C6 glioma cells were analyzed after treatment with 1 using high-resolution magic angle spinning 1H NMR. Compound 1 caused either a decrease or an increase in the intensity of the signal assigned to coenzyme A (CoA) metabolites depending on the concentration used. The data obtained from the 1H NMR spectra of cells cultured with 1, combined with those obtained after treatment with oleic acid (an inhibitor of acetyl-CoA carboxylase) and phenyl butyrate (a known antineoplastic agent), suggest that 1 may be altering the metabolism of fatty acids and induce apoptosis of C6 glioma cells. These results point to NMR spectroscopy as an efficient technique for monitoring the response of the cells to therapeutic agents.
