Highly Conformationally Restricted Cyclopropane Tethers with Three-Dimensional Structural Diversity Drastically Enhance the Cell Permeability of Cyclic Peptides

The conformation of cyclic peptides is closely related to their physicochemical and biological properties, but their rational design to obtain a conformation with the desired properties is difficult. Herein, we present a new strategy by using conformationally restricted cyclopropane tethers (CPTs) to control the conformation and improve the cell permeability of cyclic peptides regardless of the amino acid sequence. Newly designed cis- or trans-CPTs with three-dimensional structural diversity were introduced into a model cyclic peptide, and the relationship between the conformation of the cyclic peptides and their cell permeability was analyzed. Peptides containing a CPT exhibited conformational diversity due to the characteristic steric feature of cyclopropane, among which peptides containing a CPT, cis-NfCf had remarkably higher cell permeability than peptides containing other CPTs?even superior to that of cyclosporine A, a known permeable cyclic peptide.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, the role of 102029-44-7, and how the biochemistry of the body works.Electric Literature of 102029-44-7

Ethylene carbonate production by cyclocondensation of ethylene glycol and urea in the presence of metal oxides and metal acetylacetonates

A promising method for the production of ethylene carbonate is the cyclocondensation of ethylene glycol and urea in the presence of a catalyst. In this study, the catalytic effect of oxides and acetylacetonates of various metals on the occurrence of this reaction has been examined. It has been shown that cobalt acetylacetonate is the most effective catalyst. The effect of reaction conditions (temperature, pressure, contact time, and catalyst concentration) on the main parameters of catalytic conversion has been studied.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: Oxazolidin-2-one, you can also check out more blogs about497-25-6

One pot microwave-assisted synthesis of 3-benzyl-5-hydroxymethyl-1, 3-oxazolidin-2-one

Oxazolidinone is a five-member heterocyclic ring used as a privileged structure for the synthesis of ligands for different biological targets. Many synthetic approaches have been made available for oxazolidinone, however, they were found to be either time/energy consuming or multistep process. One of the approach is a one-pot method to synthesize 3-benzyl-5-hydroxymethyl-oxazolidin-2-one using reflux overnight (>12 h). The aim of the present work was to develop an improved method by the use of microwave irradiation to make 3-benzyl-5-hydroxymethyl-oxazolidin-2-one. Benzyl amine was reacted with the various carbonate salts and epichlorohydrin, in presence of bases and solvent and the reaction was carried out under open and sealed-vessel conditions. Various factors including the use of carbonate salts, base, solvent, time, temperature and power were optimized. Microwave-assisted synthesis of 3-benzyl-5-hydroxymethyl-1,3-oxazolidin-2-one gave yields of 69.59% and 77.0% in an open vessel and a closed vessel, respectively with reduction in reaction time from overnight (>12 h) to 1 h in the open vessel and to 30 min in closed vessel.

Discovery and preclinical pharmacology of a selective ATP-competitive Akt inhibitor (GDC-0068) for the treatment of human tumors

The discovery and optimization of a series of 6,7-dihydro-5H-cyclopenta[d] pyrimidine compounds that are ATP-competitive, selective inhibitors of protein kinase B/Akt is reported. The initial design and optimization was guided by the use of X-ray structures of inhibitors in complex with Akt1 and the closely related protein kinase A. The resulting compounds demonstrate potent inhibition of all three Akt isoforms in biochemical assays and poor inhibition of other members of the cAMP-dependent protein kinase/protein kinase G/protein kinase C extended family and block the phosphorylation of multiple downstream targets of Akt in human cancer cell lines. Biological studies with one such compound, 28 (GDC-0068), demonstrate good oral exposure resulting in dose-dependent pharmacodynamic effects on downstream biomarkers and a robust antitumor response in xenograft models in which the phosphatidylinositol 3-kinase-Akt-mammalian target of rapamycin pathway is activated. 28 is currently being evaluated in human clinical trials for the treatment of cancer.

Understanding the mechanism of procedure-controlled enantioselectivity switch in cinchona alkaloid thiourea catalyzed [3+2] cycloaddition: H-bonds controlled enantioselectivity

Density functional theory has been applied to the novel procedure-controlled enantioselectivity switch in the synthesis of chiral 2-oxazolidinone (3) through [3+2] cycloaddition between gamma-hydroxy-alpha,beta-unsaturated carbonyl compound (1) and isocyanate (2) catalyzed by a cinchona-alkaloid based aminothiourea catalyst. The study shows that three stages are involved in the whole process. In stage one, for Procedure A, 1 reacts with 2 to give carbamate intermediate. Then catalyst 4 is added. For Procedure B, catalyst 4 first activates 2 via quinuclidine N attacking isocyanate C. Then 1 is involved. In stage two, hydrogen is transferred from carbamate N to Ts O atom which is different from the quinuclidine N protonation mechanism. The last step is ring closure in which carbamate N attacks C atom of CC bond. From free energy profiles, the enantioselectivities of the reaction are determined by stage two. Further analysis shows that H-bond is the key in the procedure-controlled enantioselectivity switch. Different H-bonds (NAHA?OAC and NBHB?OAC in Procedure A vs NAHA?OAC and NBHB?OBS in Procedure B) lead to different relationships between thiourea and carbamate planes (vertical or parallel). In Procedure A, CC listing above carbamate plane is the favorable pathway to give R-3. However, in Procedure B, CC listing behind carbamate plane is more favorable to generate S-3.

Synthesis and absolute configuration of acanthodendrilline, a new cytotoxic bromotyrosine alkaloid from the Thai marine sponge acanthodendrilla sp.

Acanthodendrilline (1), a new bromotyrosine alkaloid, was isolated from the Thai marine sponge Acanthodendrilla sp. The structure of 1 was fully characterized by spectroscopic analysis, in agreement with the synthesized compound used to resolve the single chiral center at C-11. Total synthesis of the enantiomers of 1 allowed for the comparison of specific rotation values and hence the determination of the absolute configuration as 11-S. Cytotoxicity evaluation revealed that (S)-1 exhibited approximately three-fold more potent cytotoxicity against the human non-small cell lung cancer H292 cell line than (R)-1.
