MDM-2/p53 Agonist

Beta-Sitosterol (purity>98%) is orally active. Beta-Sitosterol exhibits multiple activities, including anti-inflammatory, anticancer, antioxidant, antimicrobial, antidiabetic, antioxidant enzyme, and analgesic. Beta-Sitosterol inhibits inflammation and impaired adipogenesis in bovine mammary epithelial cells by reducing levels of ROS, TNF-α, IL-1β, and NF-κB p65 and restoring the activity of the HIF-1α/mTOR signaling pathway. Beta-Sitosterol induces apoptosis in cancer cells through ROS-mediated mitochondrial dysregulation and p53 activation. Beta-Sitosterol exerts its anticancer effects in cancer cells by activating caspase-3, caspase-8, and caspase-9, mediating PARP inactivation, MMP loss, altered Bcl-2-Bax ratio, and cytochrome c release. Beta-Sitosterol modulates macrophage polarization and reduces rheumatoid inflammation in mice. Beta-Sitosterol inhibits tumor growth in multiple mouse cancer models. Beta-Sitosterol can be used in the research of arthritis, lung cancer, breast cancer and other cancers, diabetes, etc.

Homoeriodictyol is an orally active, bitter-tasting flavanone that can penetrate the blood-brain barrier. Homoeriodictyol enhances synaptic-related protein expression through NCOA4-mediated ferritin autophagy. Homoeriodictyol improves memory impairment in mice by inhibiting the NLRP3 inflammasome. Homoeriodictyol protects human endothelial cells from oxidative damage by activating Nrf2 and inhibiting mitochondrial dysfunction. Homoeriodictyol enhances ROS activity and induces apoptosis, exhibiting anticancer effects. Homoeriodictyol inhibits the survival and migration of androgen-resistant prostate cancer cells in vitro. Homoeriodictyol exerts antinociceptive activity in mice in vivo.

Hdm2 E3 ligase inhibitor 1 (Compound 1) is a reversible inhibitor for Hdm2 (an E3 ubiquitin ligase)-mediated ubiquitination of the p53 protein with an IC₅₀ of 12.7 μM. Hdm2 E3 ligase inhibitor 1 binds Hdm2, blocks Hdm2-catalyzed ubiquitin transfer from preligated Ub-Ubc4 to p53, inhibits p53 ubiquitination, stabilizes p53 protein in tumor cell and exhibits antitumor efficacy.

X15695 is selective and orally active estrogen receptor (ERα) degrader. X15695 is an aryl hydrocarbon receptor (AHR) ligand. X15695 enables AHR to form a complex with the ERα, promoting its proteasomal degradation. X15695 inhibits the breast cancer cells proliferation, promotes cell cycle block and induces apoptosis. X15695 can be used for the study of breast cancer.

VEGFR-2-IN-70 is a potent VEGFR-2 inhibitor with an IC₅₀ of 18.04 nM. VEGFR-2-IN-70 exhibits cytotoxicity against A549 and MCF-7 cancer cells with IC₅₀ values of 0.43 μM and 3.8 μM, respectively. VEGFR-2-IN-70 induces G1 cell cycle arrest and apoptosis in lung cancer cells. VEGFR-2-IN-70 is useful in cancer research.

L14-8 is a potent ferroptosis inducer. L14-8 promotes PLK1 degradation via ubiquitination, increasing TP53 phosphorylation to enhance SAT1 transcription, thereby triggering ferroptosis and cancer cell death. L14-8 can be used for the study of advanced prostate cancer.

Stigmast-5-en-3-ol induces cancer cell apoptosis and inhibits proliferation by increasing the production of Bax, Caspase-9, p53, and PARP cleavage and reducing Bcl-xl expression. Stigmast-5-en-3-ol exhibits potent inhibitory activity against glucoamylase and α-amylase and possesses high antioxidant activity. Stigmast-5-en-3-ol can be used in the research of diseases such as leukemia, breast cancer, type 2 diabetes, and obesity.

LLQ-45 is a covalent p53^Y220C mutant protein agonist with an EC₅₀ of 24.97 μM. LLQ-45 activates the anti-tumor function of p53^Y220C through covalent modification, restores its DNA-binding ability and enhances its thermal stability. LLQ-45 selectively inhibits the proliferation of p53^Y220C mutant tumor cells, suppresses cell growth and upregulates the expression of CDKN1A. LLQ-45 can be used in studies related to p53^Y220C mutant cancers.
