The rapid discovery of beta-glucocerebrosidase (GCase) inhibitors and pharmacological chaperones for Gaucher disease is described. The N-aminobutyl DNJ-based iminosugar was synthesized and conjugating with a variety of carboxylic acids to generate a N-diversely substituted iminosugar-based library. Several members of this library were found to be nanomolar-range inhibitors of GCase; the inhibition constant Ki of the most potent was found to be 71 nM. Although these new molecules showed reasonable chaperoning activity (1.5- to 1.9-fold) in the N370S fibroblast of Gaucher patient-derived cell line, this was accompanies by a concomitant decrease in the cellular alpha-glucosidase activity, which might limit their further therapeutic potential. Next, newly developed N-substituents were assembled with pyrrolidine-based scaffolds to generate new molecules for further evaluation. The new 2,5-dideoxy-2,5-imino-d- mannitol (DMDP)-based iminosugar 22 was found to exhibit a satisfactory chaperoning activity to enhance GCase activity by 2.2-fold in Gaucher N370S cell line, without impairment of cellular alpha-glucosidase activity.

Reference of 1679-47-6, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1679-47-6, 3-Methyldihydrofuran-2(3H)-one, introducing its new discovery.

Prior to detailed process design, it is vital to first generate a good flowsheet that meets particular objective. This is particularly the case in bio-based materials and products, where, given a range of chemistries, the synthesis problem is not about the best way to make a particular product but rather the best way to convert a specific feedstock. In order to do so, an optimisation-based framework, which can be used to identify the optimal configuration of a process network that consists of both reactions and separation systems to achieve maximum economic potential, is presented in this paper. A process superstructure, which includes the concept of master reaction stages and subsidiary separation stages, is introduced to facilitate the theory. The problem is formulated as a generalised mixed integer linear programming (MILP) model which accounts for the simultaneous selection of products and identification of the process configuration. The solution of the optimisation problem includes the best possible economic performance, identification of active reactions, reaction ordering and separation sequences along with the corresponding flowsheet of the optimal process. The economic criterion takes account of raw materials costs, product values and separation related costs. Two bio-based chemical case studies are presented to illustrate the applicability of the proposed methodology.

An efficient synthesis of low-covered polyrotaxanes grafted with poly(epsilon-caprolactone) and the mechanical properties of its cross-linked elastomers

Advanced polyrotaxane elastomers were fabricated by the synthesis of poly(epsilon-caprolactone)-grafted polyrotaxanes with significantly lower coverage than previously achieved. The time course for the complexation of alpha-cyclodextrin with an end-functionalized polyethylene glycol (PEG) was analyzed by subsequent end-capping and polyrotaxane isolation, which revealed that the bulkiness of the PEG end group affects the time required for complex nucleation and the resulting coverage. Low-coverage poly(epsilon-caprolactone)-grafted polyrotaxanes were synthesized in a facile and large-scale manner by optimizing the simultaneous hydrolysis of the end-capping groups and the solubility of the product during the ring-opening polymerization of epsilon-caprolactone. Cross-linking the thermoplastic graft polyrotaxanes yielded elastomers that are much more extensible than conventional elastomers with fivefold higher coverages. Elastomers with lower coverages behave as ideal elastic bodies due to chain sliding through the cross-links, which suggests that the arrangement entropy of the cyclic components, which counteracts chain sliding, is substantially decreased by reduced coverage.

Catalytic Friedel-Crafts Reactions on Saturated Heterocycles and Small Rings for sp3-sp2 Coupling of Medicinally Relevant Fragments

gem-Diarylheterocycles display a wide range of biological activity. Here we present a systematic study into the formation of 4- to 6-membered O- and N-heterocycles and cyclobutanes bearing the diaryl motif through a catalytic Friedel?Crafts reaction from the corresponding benzylic alcohols. 3,3-Diaryltetrahydrofurans, 4,4-diaryltetrahydropyrans, 3,3-diarylpyrrolidines, 4,4-diaryl-piperidines, as well as diarylcyclobutanes are examined, with results for 3,3-diaryloxetanes and 3,3-diarylazetidines presented for comparison. Three catalytic systems are investigated for each substrate [Ca(II), Li(I) and Fe(III)], across preinstalled aromatic groups of differing electronic character. In most cases examined, the diaryl product is obtained directly from the alcohol with good yields using the most appropriate catalyst system. In the absence of a nucleophile, the olefins from the 5- and 6-membered substrates by elimination of water are obtained under the same reaction conditions.

3-D-QSAR of N-substituted 4-amino-3,3-dialkyl-2(3H)-furanone GABA receptor modulators using molecular field analysis and receptor surface modelling study

We report the theoretical validation of the experimentally observed structure-activity relationships (SAR) of a set of N-substituted 4-amino-3,3-dialkyl-2(3H)-furanone GABA receptor modulators showing positive allosteric modulatory activity of the GABAA receptor similar to that shown by Loreclazole. Efforts were made to explain some of the conclusions drawn during this study based on a solitary instance of occurrence of the observation within the dataset. Some of the conclusions selected for study included (i) the enhanced activity for the R enantiomer of a compound, (ii) enhanced activity for a compound with an amide type functionality vis-a-vis an amine type functionality at C-4, (iii) enhanced activity for a compound with a carboxamide or carbamate type functionality linking the end group at C-4 over a compound with only the end group attached, provided the alkyl groups attached at C-3 are identical in both cases. The 3-D-QSAR method of molecular field analysis along with receptor-ligand complex stability studies were found to be the most suitable for explaining these activities. While the first conclusion was comprehensively proven, significant support was obtained in case of the latter two. Further comprehensive study is underway and we hope to report them shortly.
