The activity of acetoacetyl-CoA (AcAc-CoA) ligase (E.C.6.2.1.16) in hepatocytes from rats was shown to be the same as the activity in homogenates of their livers. In hepatocytes treated with 25-hydroxycholesterol, AcAc-CoA ligase, 3-hydroxy-3-methyl-glutaryl-CoA (HMG-CoA) reductase and rates of sterol synthesis were substantially decreased. Hepatocytes treated with high density lipoprotein (HDL...

A well-defined amphiphilic core-shell polymer functionalized with bis(p-methoxyphenylphosphino)phenylphosphine (BMOPPP) in the nanogel (NG) core has been obtained by a convergent RAFT polymerization in emulsion. This BMOPPP@NG and the previously-reported TPP@NG (TPP = triphenylphosphine) and core cross-linked micelles (L@CCM; L = TPP, BMOPPP) having a slightly different architecture were loaded...

neutral bidentate n-o type complexe of vo(ii) has been synthesized through condensation of dpenicillamine,(d-h2pen), with bis(acetylacetonate)- oxovanadium(iv),[vo(acac)2], at neutralmedium . the established schiff base(no type) complex was characterized on the basis of ir andmass spectroscopy techniques.besides,d-h2pen binding behavior to[vo(acac)2] has been studiedin thermodynamic viewpoint u...

Chemical reaction of [Ru(III)(acac)(2)(CH(3)CN)(2)]ClO(4) (1) with 2-methylthioaniline, HL(1) in ethanol under basic conditions yielded three new complexes Ru(II)(acac)(2)(L(1b)) (1b), (L(1b) = 4-imino-3-(methylsulfanyl)cyclohexa-2,5-dien-1-one), Ru(III)(acac)(2)(L(1c)) (1c), (HL(1c) = N-(2-methylthiophenyl)formamide) and (acac)(2)Ru(II)(μ-L(1d))Ru(II)(acac)(2) (1d), (L(1d) = 1,4-bis(2-methylth...

Octahedral,cuboctahedral,branched and ‘rice-like’Pt NPs were synthesised using a seed-mediated growth route. Pt NPs (3 nm) were prepared and dispersed in oleyl amine to form a seed solution and then Pt(acac)2 was added. By adjusting the molar ratio of Pt from Pt(acac)2 and seed NPs, the seed diameter and the addition route of Pt(acac)2, the NPs growth could be controlled to fall into in a kinet...

The synthesis of tetraphenylporphyrin erbium(III) acetylacetonate (acac) complexes is realized and their properties studied at the nanoscale when adsorbed on a semi-insulating CaF2/Si(100) surface. Our findings reveal that ErTPP-(acac) molecules can adsorb in two main on-site conformations. Following precisely located dI/dV measurements various specific positions [phenyls, pyrroles, Er-(acac)],...
