S6885 Ailanthone Ailanthone (AIL, Δ13-Dehydrochaparrinone), a natural anti-hepatocellular carcinoma (HCC) component in Ailanthus altissima, induces G0/G1-phase cell cycle arrest by decreasing expression of cyclins and CDKs and increases expression of p21 and p27. Ailanthone triggers DNA damage characterized by activation of the ATM/ATR pathway. Ailanthone induces apoptosis which is mitochondrion-mediated and involves the PI3K/AKT signaling pathway in Huh7 cells. Ailanthone is also a potent inhibitor of both full-length Androgen Receptor (AR-FL) and constitutively active truncated AR splice variants (AR-Vs, AR1-651) with IC50 of 69 nM and 309 nM, respectively.

S3224 Cinobufagin Cinobufagin (Cinobufagine), an active ingredient of Venenum Bufonis, inhibits tumor development. Cinobufagin increases ATM and Chk2 and decreases CDC25C, CDK1, and cyclin B. Cinobufagin inhibits PI3K, AKT and Bcl-2 while increases levels of cleaved caspase-9 and caspase-3. Thus, Cinobufagin induces cell cycle arrest at the G2/M phase and apoptosis.
S6885 Ailanthone Ailanthone (AIL, Δ13-Dehydrochaparrinone), a natural anti-hepatocellular carcinoma (HCC) component in Ailanthus altissima, induces G0/G1-phase cell cycle arrest by decreasing expression of cyclins and CDKs and increases expression of p21 and p27. Ailanthone triggers DNA damage characterized by activation of the ATM/ATR pathway. Ailanthone induces apoptosis which is mitochondrion-mediated and involves the PI3K/AKT signaling pathway in Huh7 cells. Ailanthone is also a potent inhibitor of both full-length Androgen Receptor (AR-FL) and constitutively active truncated AR splice variants (AR-Vs, AR1-651) with IC50 of 69 nM and 309 nM, respectively.

E1989New ART0380 ART0380 (IACS-030380) is a potent and selective, orally bioavailable inhibitor of ATR kinase, with an IC50 of 51.7 nM effectively inhibiting the enzyme activity of the ATR-ATRIP complex. It functions as an ATP-competitive inhibitor, binding to the ATP pocket of ATR, where ATP would typically bind. It interacts with the hinge through its morpholine oxygen and occupies the ribose pocket with a sulfoximine group. It also exhibits antitumor activity.
E1512New M3541 M3541 is a potent and selective inhibitor of ATM kinase activity with an IC50 value of 0.25 nM in cell-free assays. M3541 suppresses double-strand breaks (DSB) repair, clonogenic cancer cell growth and potentiates antitumor activity of ionizing radiation in cancer cell lines.
