Metabolite Identification
Common NameBMS-192548
DescriptionBMS-192548 is a tetracyclic compound classified as a metabolite derived from the filamentous fungus Aspergillus niger WB2346. This compound has garnered attention for its role as a binding inhibitor of neuropeptide Y (NPY) receptors, which are implicated in various physiological processes, including appetite regulation and stress response. The structure of BMS-192548 was elucidated through spectroscopic methods, confirming its tetracyclic nature (PMID:7490207 ). In pharmacological studies, BMS-192548 exhibited significant inhibitory activity against the binding of 125I-peptide YY (PYY) to NPY receptors, with IC50 values of 24 µM and 27 µM for NPY1 and NPY2 receptors, respectively (PMID:7490206 ). Furthermore, during the screening of microbial fermentation extracts, BMS-192548 was isolated through bioassay-guided fractionation, highlighting its potential as a neurokinin-1 receptor antagonist (PMID:21866960 ). Although it demonstrated weak cytotoxicity against the murine tumor cell line M-109, with an IC50 value of 240 µM (PMID:7490206 ), its primary interest lies in its receptor binding properties, making it a candidate for further research in neuropharmacology.
