  The First Potent Inhibitor of Mammalian Group X Secreted Phospholipase A₂:  Elucidation of Sites for Enhanced Binding

  摘要：

  Using the X-ray structure of human group X secreted phospholipase A(2) (hGX), we carried out structure-based design of indole-based inhibitors and prepared the compounds using a new synthetic route. The most potent compound inhibited hGX and the mouse orthologue with an IC50 of 75 nM. This compound is the most potent hGX inhibitor reported to date and was also found to inhibit a subset of the other mouse and human sPLA(2)s.

  An acid-catalyzed indole formation reaction previously reported by us was successfully applied to the preparation of variously substituted 4-hydroxy-1H-indoles 11a-g having carbon and/or heteroatom substituents at the benzene portion of the indole ring, using as substrates 3-(4, 4-dialkoxy-1-oxobutyl)-1H-pyrroles 10a-g, which are readily available from simple pyrroles in several steps. Employing one of these indoles, 11g, as a starting intermediate, an enantiospecific synthesis of the mitosene analogues 8, 9a and 9b related to antitumor antibiotics FR 900482 (1) and FR 66979 (2) was achieved by i) condensation of 20 with a chiral aldehyde 21, ii) transformation of 22a and 22b into the tricyclic compounds 29a and 29b, iii) introduction of the additional one-carbon unit as a formyl group, iv) formation of the aziridine ring, and v) removal of the benzyl protecting group. Elimination of the tert-butyloxycarbonyl group was also examined to provide the basis for a future project to synthesize 5a, the cross-linkage product of 2 and DNA.
