LYP-8
Based on 1 Customer Validation
LYP-8 is an intracellular nicotinamide phosphoribosyltransferase (iNAMPT) inhibitor with an IC50 of 0.76 μM, a reducing agent, and a tumor growth inhibitor. LYP-8 recruits VHL E3 ligase to induce iNAMPT polyubiquitination and proteasome-dependent degradation, and inhibits iNAMPT enzymatic activity. LYP-8 reduces eNAMPT levels by degrading iNAMPT to decrease eNAMPT secretion. LYP-8 reduces intracellular NAD+ levels in cancer cells and proinflammatory cytokine levels (IL-6, TNF-α) in tumor tissue and serum. LYP-8 can be used for the research of colon cancer.

Biological Activity
|
iNAMPT 0.76 μM (IC50) |
LYP-8 (0.5-5 μM; 24 h) potently degrades iNAMPT in human ovarian cancer cell line SKOV-3, with degradation rates reaching 97% and 96% at concentrations of 0.5 μM and 5 μM respectively after 24 h of treatment[1].
LYP-8 (0.01-5 μM; 24 h) induces dose-dependent degradation of iNAMPT in SKOV-3, MKN-45 and CT-26 cells, with DC50 values of 26 nM, 6.8 nM and 520 nM respectively after 24 h of treatment[1].
LYP-8 (50 nM-5 μM; 2-24 h) induces time-dependent degradation of iNAMPT in SKOV-3, MKN-45 and CT-26 cells. Downregulation of iNAMPT expression is detectable as early as 2 h in SKOV-3 cells, and iNAMPT is almost completely depleted after 24 h[1].
LYP-8 (50-100 nM; 24 h) induces iNAMPT degradation in SKOV-3 and MKN-45 cells via a mechanism that depends on binding to VHL and NAMPT and is mediated by the proteasome pathway[1].
LYP-8 (60 min) potently inhibits NAMPT enzymatic activity in cell-free biochemical assays, with an IC50 value of 0.76 μM[1].
Treatment with LYP-8 (0.1-5 μM; 24 h) induces dose-dependent degradation of intracellular iNAMPT and secreted eNAMPT in mouse colorectal cancer CT-26 cells and human ovarian cancer SKOV-3 cells[1].
LYP-8 exhibits cytotoxicity against murine colorectal cancer CT-26 cells (IC50 = 25.8 μM) and human ovarian cancer SKOV-3 cells (IC50 = 1.02 μM) following 72 h of treatment[1].
LYP-8 (100 nM; 24 h) significantly reduces intracellular NAD+ levels in SKOV-3 human ovarian cancer cells in a dose-dependent manner, with a treatment duration of 24 h[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
