The S alcohol in the benzylic position of compound 2, a key feature of a novel cholesterol lowering agent Ezetimibe, was introduced by the (R)-MeCBS catalyzed asymmetric carbonyl reduction of ketone 1 using borane tetrahydrofuran complex (BTHF) as the reducing agent. The chemo- and enantioselectivity was dramatically enhanced by using an acid as a scavenger of the stabilizer sodium borohydride present in the commercially supplied pure BTHF. The effect of the critical reaction parameters such as addition mode of reagent, temperature, acids as well as water content on the selectivity has been examined. This reaction has been successfully applied in the commercial process for the preparation of the key intermediate 2 for Ezetimibe.

Gene carriers made from polylysine are of interest in relation to gene therapy but suffer from the lack of transfection efficiency due to limited stability and endosomal escape ability. To address this problem, we designed and developed Schiff-base linked imidazole modified polylysine with a reversible-PEGylation catiomer (SL-ImPEG-SS-PLL) for high efficiency gene delivery. The reversible PEGylation was introduced for in vivo circulation, as well as selective PEG detachment to augment the cellular internalization, while introducing Schiff-base linked imidazole residues into polylysine was expected to accelerate the endosomal escape of the DNA payload, as well as facilitate intracellular DNA unpacking and release, thus significantly enhancing gene delivery efficiency. The size alteration of the SL-I15mPEG-SS-PLL/pDNA polyplexes in the presence of 10 mM GSH suggests stimulus-induced PEG detachment under tumor relevant reduction conditions. Acid-base titration assays indicate that imidazole residues confer on polylysine remarkable buffering ability. The agarose gel retardation assay suggests that the Schiff-base linkages provide an increased DNA binding ability to protect DNA against nucleases and timely intracellular DNA unpacking to permit DNA dissociation from polylysine and access to transcriptional machinery. Biological efficacy assessment of this multifunctional carrier, using pEGFP and pGL-3 as reporter genes, indicates comparable to or even higher transfection efficiencies than gold standard PEI and their transfection efficiencies are slightly affected by serum. More importantly, in vivo transfection of pEGFP reveals that GFP expression was found not only in some of the important organs, such as the liver, spleen, kidneys and lungs, but also in the transplanted carcinoma. These experimental results suggest that the reversible PEGylation and Schiff-base linked imidazole modification make SL-ImPEG-SS-PLL a great potential candidate for an effective and biocompatible gene delivery system.

Computed Properties of C15H18N2O5, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount.1676-86-4, Name is (S)-Benzyl (4-(2,5-dioxooxazolidin-4-yl)butyl)carbamate, molecular formula is C15H18N2O5.

This paper reports the pH-induced structural changes in the surface immobilized poly(l-lysine) (PLL) film. Two-dimensional (2D) correlation analysis was applied to the Fourier transform infrared (FTIR) spectra of the surface-immobilized PLL film to examine the spectral changes induced by the alternations of the protonation state of the amino group in the side chain. Significant spectral changes in the FTIR spectra of the PLL film were observed between pH 7 and 8. The decrease in the protonation state of the amino group in the side chain induced spectral changes in the amino group as well as conformational changes in the alkyl group in the side chain. From pH 1-8, the spectral changes in the amino and alkyl groups in the side chain occurred before those of the amide group in the main chain of the surface immobilized PLL film.

SAR studies of the substitution effect on the central phenyl ring of the biphenyl scaffold were carried out using anacetrapib (9a) as the benchmark. The results revealed that the new analogs with substitutions to replace trifluoromethyl (9a) had a significant impact on CETP inhibition in vitro. In fact, analogs with some small groups were as potent or more potent than the CF3 derivative for CETP inhibition. Five of these new analogs raised HDL-C significantly (>20 mg/dL). None of them however was better than anacetrapib in vivo. The synthesis and biological evaluation of these CETP inhibitors are described.
