Oxazolidinones have been synthesized by reacting glycerol carbonate or glycerol with urea in the presence of gamma-Zr phosphate as a catalyst. The conversion yield of the polyol or its carbonate depends on the temperature. Below 408 K the selectivity is 100 % with a conversion of up to 25 %, whereas increasing the temperature means that conversion yield grows, but the selectivity decreases, which makes the separation process more difficult. Starting from glycerol carbonate, two isomers, 6 and 6?, are formed with a quasi 1:1 molar ratio because urea can attack the carbonate moiety on both sides of the carboxylic CO moiety. From glycerol the formation of the 6? isomer is preferred: the ratio of 6?/6 is close to 7. The oxazolidinones formed act as templates because they interact through hydrogen bonding with glycerol. The intensity of the interaction depends on the 6 or 6? isomer: DFT calculations showed that the energy was 22.6 kcal mol-1 for 6-oxazolidinone and 25.7 kcal mol-1 for 6?-oxazolidinone. Copyright

Tumor targeting anticancer drug conjugates that contain a tumor recognition motif (homing device) are of high current relevance. Cryptophycins, naturally occurring cytotoxic cyclo-depsipeptides, have been modified by total synthesis to provide analogues suitable for conjugation to peptide-based homing devices. An array of functionalized beta2-amino acids was synthesized and incorporated into cryptophycins. All analogues proved to be highly active in the cytotoxicity assay using the human cervix carcinoma cell line KB-3-1 and its multidrug-resistant subclone KB-V1. Conformational analysis of cryptophycin-52 and two synthetic analogues was performed by NMR and MD methods to obtain information on the influence of the unit C configuration on the overall conformation. An azide-functionalized cryptophycin was connected by CuAAC to an alkyne-containing fluorescently labeled cyclic RGD-peptide as the homing device for internalization studies. Confocal fluorescence microscopy proved integrin-mediated internalization by endocytosis and final lysosomal localization of the cryptophycin prodrug.

The total synthesis of tambromycin (1), a recently isolated tetrapeptide, is reported. This unusual natural product possesses a highly modified tryptophan-derived indole fragment fused to an alpha-methylserine-derived oxazoline ring, and a unique noncanonical amino acid residue named tambroline (11). A convergent synthesis of tambromycin was achieved by a 13-step route that leveraged recent developments in the field of C-H functionalization to prepare the complex indole fragment, as well as an efficient synthesis of tambroline that featured a diastereoselective amination of homoproline.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 16251-45-9 is helpful to your research. Recommanded Product: (4S,5R)-4-Methyl-5-phenyloxazolidin-2-one

A topological virtual screening (tvs) test is presented, which is capable of identifying new drug leaders with anticonvulsant activity. Molecular structures of both anticonvulsant-active and non active compounds, extracted from the Merck Index database, were represented using topological indexes. By means of the application of a linear discriminant analysis to both sets of structures, a topological anticonvulsant model (tam) was obtained, which defines a connectivity function. On the basis of this model, 41 new structures with anticonvulsant activity have been identified by a topological virtual screening.

An improved synthesis of (2S, 4S)- and (2S, 4R)-2-amino-4-methyldecanoic acids was accomplished using a glutamate derivative as starting material and Evans’ asymmetric alkylation as the decisive step. The NMR data of the two diastereomers were measured and compared with those of the natural product. As a result, the stereochemistry of this novel amino acid unit in culicinins was assigned as (2S, 4R).

Herein, the first-generation process to manufacture Akt inhibitor Ipatasertib through a late-stage convergent coupling of two challenging chiral components on multikilogram scale is described. The first of the two key components is a trans-substituted cyclopentylpyrimidine compound that contains both a methyl stereocenter, which is ultimately derived from the enzymatic resolution of a simple triester starting material, and an adjacent hydroxyl group, which is installed through an asymmetric reduction of the corresponding cyclopentylpyrimidine ketone substrate. A carbonylative esterification and subsequent Dieckmann cyclization sequence was developed to forge the cyclopentane ring in the target. The second key chiral component, a beta2-amino acid, is produced using an asymmetric aminomethylation (Mannich) reaction. The two chiral intermediates are then coupled in a three-stage endgame process to complete the assembly of Ipatasertib, which is isolated as a stable mono-HCl salt.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.Read on for other articles about 102029-44-7Formula: C10H11NO2

A series of chiral lactam carboxamides of aminomethylpiperidine were synthesized and investigated for the collagen induced in vitro anti-platelet efficacy and collagen plus epinephrine induced in vivo pulmonary thromboembolism. The compound 31a (30 muM/kg) displayed a remarkable antithrombotic efficacy (60% protection) which was sustained for more than 24 h and points to its excellent bioavailability. The compounds 31a (IC50 = 6.6 muM) and 32a (IC50 = 37 muM), as well as their racemic mixture 28i (IC50 = 16 muM) significantly inhibited collagen-induced human platelet aggregation in vitro. Compound 34c displayed dual mechanism of action against both collagen (IC50 = 3.3 muM) and U46619 (IC50 = 2.7 muM) induced platelet aggregation. The pharmacokinetic study of 31a indicated very faster absorption, prolonged and constant systemic exposure and thereby exhibiting better therapeutic response.

Dravet syndrome is a rare and severe encephalopathy that first presents in infancy with seizures refractory to conventional antiepileptic drugs. Forty-five percent of patients report four or more tonic?clonic seizures per month despite multidrug regimens. Fenfluramine, an amphetamine derivative, was initially developed as an appetite suppressant with a serotonergic mechanism of action. Clinical observation of a potential antiepileptic activity in a small homogeneous cohort of patients combined with a genetic workup of these patients led to the hypothesis of fenfluramine as a treatment for seizures in Dravet syndrome. This concept was successfully evaluated in a zebrafish model and led to a Phase 3 trial of fenfluramine to treat seizures in children with Dravet syndrome. Preliminary results of the trial suggest that fenfluramine may be a highly effective, well-tolerated treatment for patients with Dravet syndrome. This short review summarizes the history of use of fenfluramine from the initial clinical observations followed by preclinical studies and subsequent successful clinical trial.

(Chemical Equation Presented) The type 2 intramolecular Diels-Alder (IMDA) reaction is a valuable method for synthesis of both carbocyclic and heterocyclic bridged bicyclo[5.3.1]undecane and bicyclo[4.3.1]decane ring systems. These structures are common to a number of biologically important natural products. Asymmetric variants of the type 2 IMDA reaction incorporating oxazolidinone chiral auxiliaries have been evaluated. This study has resulted in systems that deliver bridged bicyclic [5.3.1] and [4.3.1] ring systems in high diastereomeric (97-99% de) and enantiomeric purity.
