1676-86-4, Name is (S)-Benzyl (4-(2,5-dioxooxazolidin-4-yl)butyl)carbamate, belongs to oxazolidine compound, is a common compound. Formula: C15H18N2O5In an article, once mentioned the new application about 1676-86-4.

Two thermo- and pH-sensitive polypeptide-based copolymers, poly(N-isopropylacrylamide-co-N-hydroxymethylacrylamide)-b-poly(L-lysine) (P(NIPAAm-co-HMAAm)-b-PLL, P1) and poly(N-isopropylacrylamide-co-N- hydroxymethylacrylamide)-b-poly(glutamic acid) (P(NIPAAm-co-HMAAm)-b-PGA, P2), have been designed and synthesized by the ring-opening anionic polymerization of N-carboxyanhydrides (NCA) with amino-terminated P(NIPAAm-co-HMAAm). It was found that the block copolymers exhibit good biocompatibility and low toxicity. As a result of electrostatic interactions between the positively charged PLL and negatively charged PGA, P1 and P2 formed polyion complex (PIC) micelles consisting of polyelectrolyte complex cores and P(NIPAAm-co-HMAAm) shells in aqueous solution. The thermo- and pH-sensitivity of the PIC micelles were studied by UV/Vis spectrophotometry, dynamic light scattering (DLS), and transmission electron microscopy (TEM). Moreover, fluorescent PIC micelles were achieved by introducing two fluorescent molecules with different colors. Photographs and confocal laser scanning microscopy (CLSM) showed that the fluorescence-labeled PIC micelles exhibit thermo- and pH-dependent fluorescence, which may find wide applications in bioimaging in complicated microenvironments.

1676-86-4, Career opportunities within science and technology are seeing unprecedented growth across the world, and those who study chemistry or another natural science at university now have increasingly better career prospects. In a article, 1676-86-4, molcular formula is C15H18N2O5, introducing its new discovery.

In this work we compare chemical and solution properties, like critical aggregate concentrations (CAC) and hydrodynamic radii of aggregates based on either poly(ethylene glycol) or poly(sarcosine) block copolymers in aqueous solution. The amine functionalized, hydrophilic polymers poly(sarcosine) (degree of polymerization, Xn = 100 and 200) and PEG (Xn = 121 and 242) of comparable hydrodynamic volume were used to initiate the ring opening polymerization of alpha-amino acid-N-carboxyanhydrides based on epsilon-benzyl-l-glutamate (Glu(OBn)) or epsilon-carboxybenzyl-l-lysine (Lys(Z)). The second, hydrophobic block was kept at a degree of polymerization of 25 and 50 to enable a direct comparison of solution properties of block copolymers. In both cases block length could be precisely adjusted and all synthesized block copolymers have narrow molecular weight distributions and dispersities between 1.1 and 1.2. Both types of block copolymers display critical aggregate concentrations in the range of 6?10-8-3?10-7 mol/L and aggregates possess hydrodynamic radii in a range of 40-100 nm. PEG based systems, however, have a slightly lower CAC and tend to form smaller micelles, while PSar based systems have commonly smaller mu2 parameter indication more uniform aggregates.

Having gained chemical understanding at molecular level, chemistry graduates may choose to apply this knowledge in almost unlimited ways, as it can be used to analyze all matter and therefore our entire environment. In a patent, 1676-86-4, name is (S)-Benzyl (4-(2,5-dioxooxazolidin-4-yl)butyl)carbamate, introducing its new discovery. Electric Literature of 1676-86-4

Amphiphilic block copolypeptides were prepared through transition-metal- mediated polymerization of amino acid N-carboxyanhydrides. In aqueous solution these materials form strong hydrogels at low concentrations. The self-assembly process that is responsible for gelation was investigated by measuring the rheological properties of the gels for a variety of molecular architectures: poly-L-lysine-&-poly-L-leucine diblock and poly-L-lysine-b-poly-L-leucine-b- poly-L-lysine triblock copolypeptides. Experiments showed that the rodlike helical secondary structure of enantionierically pure poly-L-leucine blocks was instrumental for gelation at polypeptide concentrations as low as 0.25 wt %. The hydrophilic polyelectrolyte segments have stretched coil configurations and stabilize the twisted fibril assemblies by forming a corona around the hydrophobic core. The self-assembly of hydrophobic blocks is highly specific and sensitive to the chirality of the helices. It was found that mechanical properties of the gels can be tuned through the molecular architecture of the block copolypeptides and also by carefully mixing different polypeptides in solution.

While the job of a research scientist varies, most chemistry careers in research are based in laboratories, where research is conducted by teams following scientific methods and standards.”name: (S)-3-((S)-5-(4-Fluorophenyl)-5-hydroxypentanoyl)-4-phenyloxazolidin-2-one

The (S) alcohol in the benzylic position of compound 2, a key intermediate in the synthesis of the cholesterol lowering agent Ezetimibe, was introduced by the (R)-MeCBS catalyzed asymmetric carbonyl reduction of ketone 1 using borane diethylaniline complex (BDEA) as the reducing agent. The latter was prepared in situ from sodium borohydride (NaBH4), diethylaniline (DEA) and dimethylsulfate (DMSO4). BDEA prepared in situ offers considerable advantages from the industrialization standpoint (cost and stability on storage of the reagents) over commercial solutions of BH3-THF (BTHF) or BH3-DMS (BMS). The effect of critical reaction parameters such as addition mode of reagent, temperature, solvent, reaction quenching as well as LiCl addition on the selectivity has been examined. This reaction has been successfully applied in the process for the preparation of key intermediate 2 for Ezetimibe.

Chemistry is traditionally divided into organic and inorganic chemistry. Electric Literature of 1676-86-4, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 1676-86-4

A near infrared fluorescent polymeric drug delivery system (NIRF DDS) with pH-responsive drug release properties has been designed and developed. This material was prepared by chemical conjugation of the anticancer drug doxorubicin and hydrophobic aminocyanine dye to triblock copolypeptide via hydrazone and amide bonds, respectively. Conjugation with aminocyanine shows almost no toxicity of the material, while conjugation with doxorubicin induces pronounced toxicity on the original biocompatible material. The pH sensitive drug release nature of the near infrared fluorescent polymeric drug (NIRF prodrug) was confirmed by accelerated drug release at pH of 5.0 via an in vitro drug release experiment and gradual drug cleavage from the NIRF prodrug during a confocal laser scanning microscopic (CLSM) experiment. The CLSM experiment also reveals that the released drug subsequently migrated to the nucleus, while the polymeric residue still remained in cytoplasm, indicating that the as-prepared polymer can be a promising candidate for theranosis of cancer.
