Design of Selective Peptidomimetic Agonists for the Human Orphan Receptor BRS-3
摘要:
New tool substances may help to unravel the physiological role of the human orphan receptor BRS-3 and its possible use as a drug target for the treatment of obesity and cancer. In continuation of our work on BRS-3, the solid- and solution-phase synthesis of a library of low molecular weight peptidomimetic agonists based on the recently developed short peptide agonist 4 is described. Functional potencies of the compounds were determined measuring calcium mobilization in a fluorometric imaging plate reader (FLIPR) assay. Focusing on the N-terminus, the D-Phe-Gln moiety of 4 was modified in a combinatorial. SAR-oriented medicinal chemistry approach. With the incorporation of N-arylated glycine and alanine building blocks azaglycine, piperazine, or piperidine and the synthesis of semicarbazides and semicarbazones, a number of highly potent and selective compounds with a reduced number of peptide bonds were obtained, which also should have enhanced metabolic stability.

Antitumour compounds have the five membered fused ring ecteinascidin structure of the formula (XIV). The present compounds lack a 1,4-bridging group as found in the ecteinascidins. They have at the C-1 position a substituent selected from an optionally protected or derivatised aminomethylene group or an optionally protected or derivatised hydroxymethylene group.

The invention is directed to a method for the production of taxanes by culturing suspension cells of
Taxus
sp. in a nutrient medium that comprises an indanoyl amino acid. The indanoyl amino acid may be added in batch mode or in a feed stream at any time of the culturing. In particular, synthetic compounds 6-Ethyl-indanoyl-isoleucine, 6-Bromoindanoyl isoleucine and 1-oxo-indane-carboxy-(L)-Isoleucine-methyl ester amide (1-OII) have been found to increase taxane production from
Taxus
cell cultures.
