nz-28

NZ28, also known as NSC134754, is potent HSF1 inhibitor, which induced inhibition of HSF1, SP1 and NF-κB triggers the loss of the natural killer cell-activating ligands MICA/B on human tumor cells. Heat-shock transcription factor HSF1 has a critical role in human epidermal growth factor receptor-2-induced cellular transformation and tumorigenesis.

Isothiafludine (NZ-4) is an orally active anti-HBV compound that acts by blocking the encapsulation of pre-genomic RNA (pgRNA) and interfering with nucleosome capsid assembly, and is used in the study of HBV infections.
