WebbThe Hsp90 inhibitors, geldanamycin (GA) and radicicol, reduced fluconazole resistance in Saccharomyces cerevisiae strains with mutations in the ergosterol biosynthesis pathway . Thus, this work laid the foundations by showing that Hsp90 mediates the mechanisms that allow cells to cope with abnormal conditions such as drug-induced stress.
WebbSeveral other small molecule Hsp90 inhibitors have been reported in clinical settings including AUY922, AT13387, STA9090, and MPC3100. In a phase I dose escalation … WebbHSP90 inhibitors can enhance the radiosensitivity of multiple tumor cell lines. This is because many HSP90 clients such as Raf-1, AKT, and HER2 are associated with radio response, albeit in a cell type–dependent manner. HSP90 inhibitors can cause degradation of these proteins thus increasing apoptosis and G2 arrest (Yin et al., 2010 ).
Webb3 juni 2024 · Hsp90 (Heat shock protein 90) is involved in various processes in cancer occurrence and development, and therefore represents a promising drug target for … Webb13 feb. 2010 · The first known inhibitors of N terminus of Hsp90 were the naturally occurring products geldanamycin and radiciol [].Early experiments demonstrated that the binding of these agents to Hsp90 resulted in the degradation of the client protein v-src [].Further experiments using these agents have shown that it is the result in the …
WebbHSP90 inhibitors mainly bind to the ATP binding site of HSP90 and inhibit HSP90 activity, and these inhibitors can be distinguished as ansamycin and non-ansamycin depending on the structure. In addition, the histone deacetylase inhibitors inhibit the activity of HSP90 through acetylation of HSP90.
