Homochiral 2,4-Disubstituted 1,3-Dioxanes from (S)-(-)-Malic Acid: Stereoselective Synthesis and Investigation of the NMDA Receptor Affinity of All Four Stereoisomers

Starting from a single enantiomerically pure compound, (S)-(-)-malic acid, all four stereoisomeric 4-dimethylaminomethyl-2-phenyl-1,3-dioxanes (S,S)-15, (R,R)-15 (S,R)-16, and (R,S)-16 are prepared: Transacetalisation of benzaldehyde dimethyl acetal (6b) with (S)-(-)-methyl 2,4-dihydroxybutyrate (7a), which is obtained by chemoselective BH3 reduction of (S)-(-)-malic acid monoester 8b, yields the diastereomeric 1,3-dioxane derivatives (S,S)-10 and (R,S)-11 in a 85:15 ratio.LDA deprotonation of (S,S)-10 followed by protonation leads to C-4 epimerisation <(S,S)-10:(S,R)-11 = 30;70>.The thermodynamically controlled 88:12 equilibrium of (R,R)-10 and (S,R)-11 is reached by treatment of (S,R)-11 with acid.Aminolysis with dimethylamine and subsequent LiAlH4 reduction transform the four stereoisomeric esters (S,S)-10, (R,R)-10, (S,R)-11 and (R,S)-11 to give the amines (S,S)-15, (R,R)-15, (S,R)-16 and (R,S)-16, respectively.In the 3H-(+)-MK 801 displacement experiment (S,S)-15, (R,R)-15, (S,R)-16 and (R,S)-16 show a very little affinity to the phencyclidine binding site in the cation channel associated with the NMDA receptor. – Key Words: Butyric acid derivatives, (S)-(-)-24-dihydroxy-/ 1,3-Dioxanes/ NMDA antagonists, noncompetitive

A Fluorescence Polarization Activity-Based Protein Profiling Assay in the Discovery of Potent, Selective Inhibitors for Human Nonlysosomal Glucosylceramidase

Human nonlysosomal glucosylceramidase (GBA2) is one of several enzymes that controls levels of glycolipids and whose activity is linked to several human disease states. There is a major need to design or discover selective GBA2 inhibitors both as chemical tools and as potential therapeutic agents. Here, we describe the development of a fluorescence polarization activity-based protein profiling (FluoPol-ABPP) assay for the rapid identification, from a 350+ library of iminosugars, of GBA2 inhibitors. A focused library is generated based on leads from the FluoPol-ABPP screen and assessed on GBA2 selectivity offset against the other glucosylceramide metabolizing enzymes, glucosylceramide synthase (GCS), lysosomal glucosylceramidase (GBA), and the cytosolic retaining beta-glucosidase, GBA3. Our work, yielding potent and selective GBA2 inhibitors, also provides a roadmap for the development of high-throughput assays for identifying retaining glycosidase inhibitors by FluoPol-ABPP on cell extracts containing recombinant, overexpressed glycosidase as the easily accessible enzyme source.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 15833-61-1, help many people in the next few years.15833-61-1

A Comprehensive Study on Metal Triflate-Promoted Hydrogenolysis of Lactones to Carboxylic Acids: From Synthetic and Mechanistic Perspectives

Direct hydrogenolysis of lactone to carboxylic acid (i.e., hydrogenolysis of the Calkoxy-O bond with the carbonyl group untouched) is generally difficult, as the current strategies employing Br¡ãnsted acids as the catalyst usually require harsh conditions such as a high temperature and a high H2 pressure. Herein, we report a developed solvent-free catalytic transformation, in which W(OTf)6 is believed to promote the hydrogenolysis process. This strategy could efficiently hydrogenate lactones to carboxylic acids under extra mild conditions (e.g., a reaction temperature of <150 C and 1 atm of H2) and showed a broad substrate scope. In addition, the catalytic protocol can be further applied to the hydrogenolysis of polyhydroxyalkanoate, as a renewable polymer, to the corresponding straight-chain carboxylic acids. An extensive mechanistic study was subsequently performed, and the density functional theory calculations revealed a reaction pattern, including the complete cleavage of the C=O bond with the assistance of the W(OTf)6 catalyst. Moreover, the key intermediate created in the mechanism, as an oxonium with an OTf moiety, was successfully detected by electrospray ionization mass spectra. Through a comparison with the Br¡ãnsted acid-catalyzed system, the study confirmed that the existence of the OTf moiety can significantly lower the barriers associated with the rearrangement and elimination processes. Meanwhile, emphasis was placed on the critical role that the anion plays, as well as the fact that the anion effect is directly related to the chemoselectivity. 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.4344-84-7, you can also check out more blogs about4344-84-7

Discovery of 4-(((4-(5-chloro-2-(((1s,4s)-4-((2-methoxyethyl)amino)cyclohexyl)amino)pyridin-4-yl)thiazol-2-yl)amino)methyl)tetrahydro-2H-pyran-4-carbonitrile (JSH-150) as a novel highly selective and potent CDK9 kinase inhibitor

Through a structure-guided rational drug design approach, we have discovered a highly selective inhibitor compound 40 (JSH-150), which exhibited an IC50 of 1 nM against CDK9 kinase in the biochemical assay and achieved around 300?10000-fold selectivity over other CDK kinase family members. In addition, it also displayed high selectivity over other 468 kinases/mutants (KINOMEscan S score(1) = 0.01). Compound 40 displayed potent antiproliferative effects against melanoma, neuroblastoma, hepatoma, colon cancer, lung cancer as well as leukemia cell lines. It could dose-dependently inhibit the phosphorylation of RNA Pol II, suppress the expression of MCL-1 and c-Myc, arrest the cell cycle and induce the apoptosis in the leukemia cells. In the MV4-11 cell-inoculated xenograft mouse model, 10 mg/kg dosage of 40 could almost completely suppress the tumor progression. The high selectivity and good in vivo PK/PD profile suggested that 40 would be a good pharmacological tool to study CDK9-mediated physiology and pathology as well as a potential drug candidate for leukemia and other cancers.
