Dirigent Proteins Guide Asymmetric Heterocoupling for the Synthesis of Complex Natural Product Analogues

Phenylpropanoids are a class of abundant building blocks found in plants and derived from phenylalanine and tyrosine. Phenylpropanoid polymerization leads to the second most abundant biopolymer lignin while stereo- and site-selective coupling generates an array of lignan natural products with potent biological activity, including the topoisomerase inhibitor and chemotherapeutic etoposide. A key step in etoposide biosynthesis involves a plant dirigent protein that promotes selective dimerization of coniferyl alcohol, a common phenylpropanoid, to form (+)-pinoresinol, a critical C2 symmetric pathway intermediate. Despite the power of this coupling reaction for the elegant and rapid assembly of the etoposide scaffold, dirigent proteins have not been utilized to generate other complex lignan natural products. Here, we demonstrate that dirigent proteins from Podophyllum hexandrum in combination with a laccase guide the heterocoupling of natural and synthetic coniferyl alcohol analogues for the enantioselective synthesis of pinoresinol analogues. This route for complexity generation is remarkably direct and efficient: three new bonds and four stereocenters are produced from two different achiral monomers in a single step. We anticipate our results will enable biocatalytic routes to difficult-to-access non-natural lignan analogues and etoposide derivatives. Furthermore, these dirigent protein and laccase-promoted reactions of coniferyl alcohol analogues represent new regio- and enantioselective oxidative heterocouplings for which no other chemical methods have been reported.

NOVEL BIAROMATIC COMPOUNDS THAT ACTIVATE PPAR TYPE RECEPTORS, AND USE THEREOF IN COSMETIC OR PHARMACEUTICAL COMPOSITIONS

The invention relates to novel biaromatic compounds that correspond to the general formula (I) and also to the method for preparing them, and to their use in pharmaceutical compositions for use in human or veterinary medicine (in dermatology, and also in the field of cardiovascular diseases, immune diseases and/or lipid metabolism-related diseases), or alternatively in cosmetic compositions.

TRICYCLIC COMPOUNDS USEFUL AS SEROTONIN INHIBITORS AND 5-HT1A AGONISTS AND ANTAGONISTS

3-Amino chroman and 2-amino tetralin derivatives and compositions containing such compounds are disclosed. Such compounds are useful for modulating activity of a 5-HT1A receptor (agonizing or antagonizing) in a patient. These compounds are further useful for inhibiting binding to a serotonin receptor. Methods of using the 3-amino chroman and 2-amino tetralin compounds and compositions containing such compounds in the treatment of serotonin disorders, such as depression and anxiety, are also disclosed.
