Description of:LW6(cas:934593-90-5)
LW8 was found to inhibits the accumulation of HIF-1alpha. LW6 decreased HIF-1alpha protein expression without affecting HIF-1beta expression. It was further found that LW8 promoted the degradation of wild type HIF-1alpha, but not of a DM-HIF-1alpha with modifications of P402A and P564A, at hydroxylation sites in the oxygen-dependent degradation domain (ODDD). LW6 did not affect the activity of prolyl hydroxylase (PHD), but induced the expression of von Hippel-Lindau (VHL), which interacts with prolyl-hydroxylated HIF-1alpha for proteasomal degradation. In the presence of LW8, knockdown of VHL did not abolish HIF-1alpha protein accumulation, indicating that LW8 degraded HIF-1alpha via regulation of VHL expression. In mice carrying xenografts of human colon cancer HCT116 cells, LW8 demonstrated strong anti-tumor efficacy in vivo and caused a decrease in HIF-1alpha expression in frozen-tissue immunohistochemical staining. These data suggest that LW8 may be valuable in the development of a HIF-1alpha inhibitor for cancer treatment. (source: Biochem Pharmacol. 2010 Oct 1;80(7):982-9.) LW6 decreases HIF-1α protein expression without affecting HIF-1β expression. LW6 affects the stability of the HIF-1α protein. LW6 promotes the degradation of wild type HIF-1α, but not of a DM-HIF-1α with modifications of P402A and P564A, at hydroxylation sites in the oxygen-dependent degradation domain. LW6 induces the expression of von Hippel-Lindau (VHL), which interacts with prolyl-hydroxylated HIF-1α for proteasomal degradation. In the presence of LW6, knockdown of VHL does not abolish HIF-1α protein accumulation, indicating that LW6 degraded HIF-1α via regulation of VHL expression[2]. In MDCKII-BCRP cells overexpressing BCRP, LW6 enhances significantly the cellular accumulation of mitoxantrone, a BCRP substrate. LW6 also down-regulates BCRP expression at concentrations of 0.1-10 µM[3]. LW6 inhibits the expression of HIF 1α induced by hypoxia in A549 cells at 20 mM, independently of the von Hippel Lindau protein. LW6 induces hypoxia selective apoptosis together with a reduction in the mitochondrial membrane potentia Quality control data: Quality control by 1H-NMR, 13C-NMR, HPLC and LCMS.
