Technical Data
Kijanimicin (Antibiotic Sch 25663)
Biochemicals Storage: -20CShipping: Blue Ice
Kijanimicin is a tetronic acid related to saccharocarcin, chlorothricin, versipelostatin and tetrocarcin. Like the tetrocarcins, kijanimicin contains an unusual nitro-aminoglycoside. Kijanimicin is a potent antibacterial, antimalarial and antitumor activity. However, several members of this class have received considerable literature focus. Versipelostatin was shown to inhibit transcription from the promoter of GRP78, a gene that is activated as part of a stress signaling pathway under glucose deprivation resulting in unfolded protein response (UPR). The UPR-inhibitory action was seen only in conditions of glucose deprivation and caused selective and massive killing of the glucose-deprived cells. While tetrocarcin A appears to target the phosphatidylinositide-3'-kinase/Akt signaling pathway.
