Chemistry can be defined as the study of matter and the changes it undergoes. category: oxazolidine. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.category: oxazolidine, Name is (R)-4-Benzyl-3-(3-methylbutanoyl)oxazolidin-2-one, molecular formula is C15H19NO3, introducing its new discovery.

We report a “macrocycle route” toward aliskiren, a drug presently marketed for the treatment of hypertension, using a highly stereocontrolled approach starting from a common “isopropyl chiron”. Highlights of the synthesis include a challenging RCM reaction to produce a nine-membered unsaturated lactone, a highly stereoselective catalytic Du Bois aziridination, and a regio- and diastereoselective aziridine ring-opening to a vicinal amino alcohol.

Novel nonpeptide small molecule renin inhibitors bearing an N-isopropyl P1 motif were designed based on initial lead structures 1 and aliskiren (2). (P3-P1)-Benzamide derivatives such as 9a and 34, as well as the corresponding P1 basic tertiary amine derivatives 10 and 35 were found to display low nanomolar inhibition against human renin in vitro.

The present invention is directed to compositions comprising lysophosphatidic acid analogs and methods of using such analogs as agonist or antagonists of LPA receptor activity. In addition the invention is directed to LPA receptor agonists that vary in the degree of selectivity at individual LPA receptors (i.e. LPA1, LPA2 and LPA3). More particularly the present invention is directed to LPA analogs wherein the glycerol is replaced with ethanolamine and a variety of substitutions have been linked at the second carbon atom.

PEG-based polyplex micelles, which can detach the surrounding PEG chains responsive to the intracellular reducing environment, were developed as nonviral gene vectors. A novel block catiomer, PEG-SS-P[Asp(DET)], was designed as follows: (i) insertion of biocleavable disulfide linkage between PEG and polycation segment to trigger PEG detachment and (ii) a cationic segment based on poly(aspartamide) with a flanking N-(2-aminoethyl)-2-aminoethyl group, P[Asp(DET)], in which the Asp(DET) unit acts as a buffering moiety inducing endosomal escape with minimal cytotoxicity. The polyplex micelles from PEG-SS-P[Asp(DET)] and plasmid DNA (pDNA) stably dispersed in an aqueous medium with a narrowly distributed size range of ?80 nm due to the formation of hydrophilic PEG palisades while undergoing aggregation by the addition of 10 mM dithiothreitol (DTT) at the stoichiometric charge ratio, indicating the PEG detachment from the micelles through the disulfide cleavage. The PEG-SS-P[Asp(DET)] micelles showed both a 1-3 orders of magnitude higher gene transfection efficiency and a more rapid onset of gene expression than PEG-P[Asp(DET)] micelles without disulfide linkages, due to much more effective endosomal escape based on the PEG detachment in endosome. These findings suggest that the PEG-SS-P[Asp(DET)] micelle may have promising potential as a nonviral gene vector exerting high transfection with regulated timing and minimal cytotoxicity.

Synthetic Route of 13590-42-6, Chemical engineers work across a number of sectors, processes differ within each of these areas, but chemistry and chemical engineering roles are found throughout in the manufacturing process of chemical products. 13590-42-6, Name is (S)-Benzyl 2-(2,5-dioxooxazolidin-4-yl)acetate, molecular formula is C12H11NO5

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.

Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations.

In view of the prominent role of the 1H-indol-3-yl side chain of tryptophan in peptides and proteins, it is important to have the appropriately protected homologs H-beta2-HTrp-OH and H-beta3-HTrp-OH (Fig.) available for incorporation in beta-peptides. The beta2-HTrp building block is especially important, because beta2-amino acid residues cause beta-peptide chains to fold to the unusual 12/10 helix or to a hairpin turn. The preparation of Fmoc- and Z-beta2-HTrp(Boc)-OH by Curtius degradation (Scheme 1) of a succinic acid derivative is described (Schemes 2 – 4). To this end, the (S)-4-isopropyl-3-[(N-Boc-indol-3-yl)propionyl]-1,3-oxazolidin-2-one enolate is alkylated with Br-CH2CO2Bn (Scheme 3). Subsequent hydrogenolysis, Curtius degradation, and removal of the Evans auxiliary group gives the desired derivatives of (R)-H-beta2-HTrp-OH (Scheme 4). Since the (R)-form of the auxiliary is also available, access to (S)-beta2-HTrp-containing beta-peptides is provided as well.

Dendritic polymers represent a class of materials for prospective drug delivery application. For that purpose we present the synthesis and characterization of hydrophilic, anionic core-shell architectures based on poly(ethylene imine) (PEI) as core molecule and polyamino acid chains (composed of glutamic acid or aspartic acid) as shell component. NCA polymerization is used for coupling polyamino acid chains to PEI scaffold. Modifying these structures with sugar molecules result in the formation of new core-shell architectures combining a mixture of binary and double shell. For their potential biomedical applications the solution properties of these anionic core-shell architectures at various pH values (3-9) were studied by different analytical tools (zeta potential, streaming potential pH titration, DLS, AFM, in-situ AFM, TEM and cryo-TEM). Especially, the sugar-decorated core-shell architectures mainly provide isolated macromolecules over a broad pH range. Furthermore, the anionic core-shell architectures are suited to interact with cationic molecules.

The unusual sphingoid base 5-hydroxy-3-sphingenine was identified in the hydrolysate of brain sphingolipids more than 40 years ago. We present here the first synthesis of the 5R and 5S diastereoisomers of the N-acyl derivatives of 5-hydroxy-3-sphingenine, 2 and 3, respectively, which represent regioisomers of (2S,3R)-ceramide (1). The key steps include the synthesis of a,beta-unsaturated ketone intermediates 4 and 5 from N-Cbz- and N-Boc -L-serine and diastereoselective reduction of the enones. The configuration at the new carbinol center was deduced by proton NMR analysis of (R)- and (S)-Mosher [methoxy(trifluoromethyl)phenylacetate] ester derivatives. Ceramide analogues 2 and 3 showed a markedly higher antiproliferative activity than 1 on MCF-7 cells.
