  • Patent number: 5977117
    Abstract: Methods, compositions, and compounds for modulating the activity of an endothelin peptide are provided. The methods use compositions that contain compounds of formula (I): ##STR1## where X and Y are selected from groups that include O, S, and NH; and Ar.sup.1, Ar.sup.2 and Ar.sup.3 are independently selected from substituted or unsubstituted groups that include 5 to 6 membered aryl groups and heteraryl groups that contain one or two heteroatom(s). The methods are effected by contacting endothelin receptors with one or more of the compounds or with compositions containing one or more of the compounds prior to, simultaneously with, or subsequent to contacting the receptors with an endothelin peptide.

  • Patent number: 5786507
    Abstract: Process for the preparation of 3-phenylpropionic acid in which 3-phenylpropanal is subjected to an oxidation, at elevated temperature, in particular at a temperature of between 40.degree. and 80.degree. C., using a medium containing molecular oxygen. A high degree of conversion and a high selectivity are obtained. The starting material 3-phenylpropanal can be prepared in a suitable manner through the hydrogenation of cinnamaldehyde in the presence of a Pd-containing catalyst, after which the reaction mixture obtained can without intermediate further processing be used in the oxidation reaction. The combination of the two process steps constitutes a simple, commercially attractive process for the preparation of 3-phenylpropionic acid using cinnamaldehyde as a starting material. 3-phenylpropionic acid can be used in particular in the preparation of pharmaceuticals such as HIV protease inhibitors.
