Enantio- and Diastereoselective, Complete Hydrogenation of Benzofurans by Cascade Catalysis

We report an enantio- and diastereoselective, complete hydrogenation of multiply substituted benzofurans in a one-pot cascade catalysis. The developed protocol facilitates the controlled installation of up to six new defined stereocenters and produces architecturally complex octahydrobenzofurans, prevalent in many bioactive molecules. A unique match of a chiral homogeneous ruthenium-N-heterocyclic carbene complex and an in situ activated rhodium catalyst from a complex precursor act in sequence to enable the presented process.

Immunoproteasome Inhibitor-Doxorubicin Conjugates Target Multiple Myeloma Cells and Release Doxorubicin upon Low-Dose Photon Irradiation

Proteasome inhibitors are established therapeutic agents for the treatment of hematological cancers, as are anthracyclines such as doxorubicin. We here present a new drug targeting approach that combines both drug classes into a single molecule. Doxorubicin was conjugated to an immunoproteasome-selective inhibitor via light-cleavable linkers, yielding peptide epoxyketone-doxorubicin prodrugs that remained selective and active toward immunoproteasomes. Upon cellular uptake and immunoproteasome inhibition, doxorubicin is released from the immunoproteasome inhibitor through photoirradiation. Multiple myeloma cells in this way take a double hit: immunoproteasome inhibition and doxorubicin-induced toxicity. Our strategy, which entails targeting of a cytotoxic agent, through a covalent enzyme inhibitor that is detrimental to tumor tissue in its own right, may find use in the search for improved anticancer drugs.

Method suitable for large-scale production of B-RAF kinase dimer inhibitor

The invention relates to a method for large-scale production of a B-RAF kinase dimer inhibitor 1-((1S, 1aS, 6bS)-5-((7-oxo-5, 6, 7, 8-tetrahydro-1, 8-diazanaphthalene-4-yl) oxy)-1a, 6b-dihydro-1H-cyclopropyl [b] benzofuran-1-yl)-3-(2, 4, 5- trifluorophenyl) urea (hereinafter sometimes referred to as a compound 1). The method enables impurities or by-products to be controlled to 0.05% or less without the use of expensive column chromatography operations. Thus, the method greatly reduces cost and is suitable for large-scale production.

Total Asymmetric Synthesis of (+)-Paroxetine and (+)-Femoxetine

Total, asymmetric synthesis of (+)-Paroxetine and (+)-Femoxetine, selective serotonin reuptake inhibitors, used for the treatment of depression, anxiety, and panic disorders is reported. The key step is organocatalytic Michael addition of aldehydes to trans-nitroalkenes realized in bath or continues flow. High efficiency and selectivity in the Michael addition was achieved by application of Wang resin-supported Hayashi–J?rgensen catalyst.

New heteroaryl carbamates: Synthesis and biological screening in vitro and in mammalian cells of wild-type and mutant HIV-protease inhibitors

New heteroaryl HIV-protease inhibitors bearing a carbamoyl spacer were synthesized in few steps and high yield, from commercially available homochiral epoxides. Different substitution patterns were introduced onto a given isopropanoyl-sulfonamide core that can have either H or benzyl group. The in vitro inhibition activity against recombinant protease showed a general beneficial effect of both carbamoyl moiety and the benzyl group, ranging the IC50 values between 11 and 0.6 nM. In particular, benzofuryl and indolyl derivatives showed IC50 values among the best for such structurally simple inhibitors. Docking analysis allowed to identify the favorable situation of such derivatives in terms of number of interactions in the active site, supporting the experimental results. The inhibition activity was also confirmed in HEK293 mammalian cells and was maintained against protease mutants. Furthermore, the metabolic stability was comparable with that of the commercially available inhibitors.

Dioxazolones as masked ester surrogates in the Pd(ii)-catalyzed direct C-H arylation of 6,5-fused heterocycles

A simple and effective Pd(ii)-catalyzed regioselective C(2)-H arylation of 6,5-fused heterocycles with dioxazolones as a masked ester surrogate under mild conditions is reported. The significance of the arylation is highlighted by the new reactivity demonstrated in dioxazolones via proximal C-H activation of the cyclic carbonate of the hydroxamic acid functionality under protic conditions.
