PNC-27

Product Details: PNC-27 (10mg)

PNC-27 is a lab-made peptide. It is a synthetic p53-derived peptide containing an HDM-2 binding domain. It is being studied in experimental and preclinical models for its interaction with membrane-associated HDM-2 proteins expressed in abnormal cell lines. 

These interactions play a significant role in regulating various cellular pathways, including necrotic membrane disruption and cell membrane integrity in laboratory settings.

Originally investigated for its role in tumor suppressor-related pathways, PNC-27 has gained research interest due to its selective activity on HDM-2-expressing cell membranes. 

Its defined peptide structure and receptor selectivity make it an excellent compound for studying peptide-membrane interactions and necrotic membrane disruption mechanisms in controlled experimental environments.

Mechanism of Action

In preclinical and experimental settings, PNC-27 is characterized as an HDM-2-targeting peptide. It demonstrates notable affinity for membrane-bound HDM-2 proteins overexpressed in abnormal cell models within in vitro systems. Activation of this interaction is studied for its effects on membrane destabilization and downstream necrosis.

Through targeted binding, PNC-27 is used in laboratory research to investigate HDM-2-mediated membrane disruption, apoptotic pathway activation, and peptide-driven cell regulatory mechanisms. Its selectivity for HDM-2-expressing membranes allows researchers to examine receptor-specific responses and downstream biochemical processes in controlled systems.

Importantly, published preclinical studies consistently characterize PNC-27-induced cell death as necrosis, not apoptosis. Necrosis was confirmed via LDH release assays and the absence of apoptotic markers in HDM-2-expressing cancer cell lines. This mechanistic distinction is documented in all primary published references for this compound." [Sarafraz-Yazdi et al., 2010; Fenelus et al., 2020]
