The present invention relates to a compound having the following formula (I): (I) wherein: - R is a (C1-C6)alkyl group;- R'' is preferably H;- Ar is a (C5-C12)arylene radical;- X1 is -C(=O)- or -SO2-; and- R' is chosen from the group consisting of possibly substituted (C1-C6)alkyl, heteroaryl, (C5-C12)aryl, and (hetero)cycloalkyl groups, or a pharmaceutically acceptable salt and/or tautomeric form thereof, or its racemates, diastereomers or enantiomers.
Identification of human T2R receptors that respond to bitter compounds that elicit the bitter taste in compositions, and the use thereof in assays to identify compounds that inhibit (block) bitter taste in compositions and use thereof

Page/Page column 145, (2016/02/26)
The present invention relates to the discovery that specific human taste receptors in the T2R taste receptor family respond to particular bitter compounds present in, e.g., coffee. Also, the invention relates to the discovery of specific compounds and compositions containing that function as bitter taste blockers and the use thereof as bitter taste blockers or flavor modulators in, e.g., coffee and coffee flavored foods, beverages and medicaments. Also, the present invention relates to the discovery of a compound that antagonizes numerous different human T2Rs and the use thereof in assays and as a bitter taste blocker in compositions for ingestion by humans and animals.

A practical and scalable route to the Wnt inhibitor SEN461 1 is described herein. The optimized route consists of nine chemical steps. The intermediates are solids and were isolated by filtrations. Critical reactions steps in the medicinal chemistry route were modified for an initial scale-up process, and as a result, we developed a synthetic procedure for the preparation of multihundred gram quantities of the final product. A further process development for the phase 1 clinical batch campaign is reported.

A series of amino acid methyl ester hydrochlorides were prepared in good to excellent yields by the room temperature reaction of amino acids with methanol in the presence of trimethylchlorosilane. This method is not only compatible with natural amino acids, but also with other aromatic and aliphatic amino acids.
