Cat.No. 6156 - VH 298 | C27H33N5O4S | CAS No. 2097381-85-4
Description: High-affinity inhibitor of VHL
Chemical Name: (2S,4R)-1-((S)-2-(1-cyanocyclopropanecarboxamido)-3,3-dimethylbutanoyl)-4-hydroxy-N-(4-(4-methylthiazol-5-yl)benzyl)pyrrolidine-2-carboxamide
Purity: ≥98% (HPLC)

Biological Activity

High-affinity inhibitor of E3 ubiquitin ligase VHL (Kd = 80-90 nM). Blocks interaction between VHL and HIF-α downstream of HIF-α hydroxylation, initiating hypoxic response. Results in time- and concentration-dependent accumulation of hydroxylated HIF-α, and upregulates mRNA and protein levels of HIF target genes. Cell permeable. Negative control cis VH 298 also available.

Programmed Cell Death

Programmed Cell Death Poster

There are two currently recognized forms of programmed cell death: apoptosis and necroptosis. This poster summarizes the signaling pathways involved in apoptosis, necroptosis and cell survival following death receptor activation, and highlights the influence of the molecular switch, cFLIP, on cell fate.
