ATM/ATR Activator

FEN1-IN-1 (compound 1) is a small molecule flap endonuclease 1 (FEN1) inhibitor with antitumor activity. FEN1-IN-1 binds to the active site of FEN1 and partly achieves inhibition by the co-ordination of Mg²⁺ ions. FEN1-IN-1 initiaties a DNA damage response and activates the ATM checkpoint signalling pathway, the phosphorylation of histone H2AX and the ubiquitination of FANCD2 in mammalian cells. FEN1-IN-1 is promising for research of cancers.

Adefovir dipivoxil is an orally active adenosine analog and Adefovir prodrug. Adefovir dipivoxil inhibits DNA synthesis, activates the ATR signaling pathway, and disrupts the KCTD12-CDK1 interaction. Adefovir dipivoxil has antiviral activity against PRV, HBV, and orthopoxviruses. Adefovir dipivoxil has inhibitory effects on both lamivudine-resistant and wild-type strains. Adefovir dipivoxil has antitumor activity against lung and colon cancer.

Garcinone C, a xanthone derivative, is a natural compound extracted from Garcinia oblongifolia that is used as an anti-inflammatory, astringency and granulation-promoting medicine, and has potential cytotoxic effects on certain cancers. Garcinone C stimulates the expression levels of ATR and 4E-BP1, arrests the cell cycle, inhibits cell viability of the human Nasopharyngeal carcinoma (NPC) cell lines CNE1, CNE2, HK1 and HONE1 in a time‑ and dose‑dependent manner through inhibition of Hedgehog signaling pathway. Garcinone C is orally active.

Theasaponin E1 is an orally effective tea saponin. Theasaponin E1 inhibits the proliferation of cancer cells by activating apoptosis. Theasaponin E1 inhibits angiogenesis in ovarian cancer cells and HUVECs by reducing the expression of VEGF. Theasaponin E1 upregulates the phosphorylation level of ATM protein and the expression level of PTEN protein in cancer cells, decreases the phosphorylation levels of Akt, mTOR, p70S6K and 4E-BP1 proteins, downregulates the expression of HIF-1α and NF-κB, and reduces the protein expression of Notch ligands Dll4 and Jagged1. Theasaponin E1 exerts neuroprotective effects by inhibiting the activity of acetylcholinesterase, activating α-secretase and neprilysin, reducing the concentration of Aβ, and inhibiting the activities of β-secretase and γ-secretase. Theasaponin E1 exhibits toxic effects on cancer cells and quinone reductase-inducing activity, and inhibits tumor growth in vivo. Theasaponin E1 induces ferroptosis in Pomacea canaliculata by synergistically disrupting cholesterol homeostasis and sphingolipid metabolism. Theasaponin E1 possesses anti-biofilm activity against Candida albicans. Theasaponin E1 can be used in the research of ovarian cancer, obesity, Alzheimer's disease and fungal infections.

GJ071 oxalate induces ATM kinase activity in ataxia telangiectasia (A-T) cells carrying homozygous TGA or TAG stop codons.

Murabutide is an immunomodulator and also a NOD2 receptor agonist. Murabutide enhances the signal transduction of ATR and NOD2, mediates the activation of the DDR pathway, and thereby repairs radiation-induced DNA double-strand breaks. Murabutide inhibits radiation-induced cell apoptosis and protects cells and mice from radiation-induced toxic damage. Murabutide induces the expression and DNA-binding activity of Oct-1 in macrophages, thereby inhibiting the transcription and replication of HIV-1. Murabutide reduces the expression levels of CD4 and CCR5 on the surface of macrophages, and induces the secretion of β-chemokines, TNF-α and IL-6. Murabutide enhances non-specific viral resistance and targets reticuloendothelial cells. Murabutide can be used in research related to radiation-induced damage and human immunodeficiency virus type 1 infection.

Garcinone C (Standard) is the analytical standard of Garcinone C. This product is intended for research and analytical applications. Garcinone C, a xanthone derivative, is a natural compound extracted from Garcinia oblongifolia that is used as an anti-inflammatory, astringency and granulation-promoting medicine, and has potential cytotoxic effects on certain cancers. Garcinone C stimulates the expression levels of ATR and 4E-BP1, arrests the cell cycle, inhibits cell viability of the human Nasopharyngeal carcinoma (NPC) cell lines CNE1, CNE2, HK1 and HONE1 in a time‑ and dose‑dependent manner through inhibition of Hedgehog signaling pathway. Garcinone C is orally active.

Americanin A is a Neolignan. Americanin A can be isolated from the seeds of Phytolacca americana. Americanin A activates ATM and ATR, initiating the subsequent signal transduction cascades that include Chk1, Chk2, and tumor suppressor p53. Americanin A targets selectively Skp2 for degradation and thereby stabilizes p27. Americanin A suppresses the activity of Cyclin B1 and its partner cdc2 to prevent entry into Mitosis. Americanin A induces Apoptosis by producing excessive ROS. Americanin A has anti-cancer activity against colorectal cancer.
