MedKoo Cat#: 571063 | Name: HLI98C

Description:

WARNING: This product is for research use only, not for human or veterinary use.

HLI98C is a HDM2 ubiquitin ligase inhibitor. HLI98C exhibits cytotoxic activities and HDM2 E3 ligase inhibitory activities. In cells, HLI98C allows the stabilization of p53 and HDM2 and activation of p53-dependent transcription and apoptosis. The p53 tumor suppressor protein is regulated by its interaction with HDM2, which serves as a ubiquitin ligase (E3) to target p53 for degradation. HLI98C may demonstrate anti-tumor activity by inhibiting recognition of the E3 enzyme and substrate.

More Info
The tumor suppressor protein p53 plays an important role in preventing cancer development by inhibiting the proliferation of cells undergoing tumorigenic stress, such as DNA damage or oncogene activation One of the principal E3s responsible for targeting the degradation of p53, and keeping p53 levels low during normal growth and development, is HDM2. In response to oncogenic stress, the degradation of p53 by HDM2 is inhibited, leading to a rapid increase in p53 protein levels in the cell, which is then controlled by degradation of normal p53 levels. The binding of HLI98 to HDM2 does not inhibit the interaction of HDM2 with p53, but appears to block the ubiquitylation and degradation of p53. In the protein ubiquitination cascade, ubiquitin (Ub) conjugation to a lysine residue on the target protein is catalyzed three enzymes: ubiquitin-activating enzyme (E1), ubiquitin conjugating enzyme (E2), and ubiquitin ligase (E3). In recent years, a variety of small-molecule inhibitors for ubiquitination have been discovered.
