Herbimycin A
0 ImagesHerbimycin A is an antibiotic and protein tyrosine kinase inhibitor. Herbimycin A directly inhibits the autophosphorylation of p210 BCR-ABL with an IC50 of approximately 5 μM, and reduces Src kinase activity. Herbimycin A also induces the degradation of receptor tyrosine kinases such as insulin-like growth factor 1 receptor (IGF-1R), insulin receptor (IR) and epidermal growth factor receptor (EGFR) via the ubiquitin-20S proteasome pathway. Herbimycin A directly modifies NF-κB p50, with the main target site involving Cys62, thereby blocking the DNA binding of p50 and NF-κB-driven gene expression. Herbimycin A can be used in studies related to tyrosine kinase signaling, chronic myeloid leukemia, NF-κB signaling, osteoclast function, apoptosis and cellular stress.
