SR15006 is Krüppel-like factor 5 (KLF5) inhibitor (IC50 = 41.6 nM).

Aminopurvalanol A is a competitive, selective and cell-permeable inhibitor of cyclin-dependent kinase (CDK) that potently inhibits Cyclin A cdk2, Cyclin B cdk1, Cyclin E cdk2, and P35 cdk5 with IC50 of 33 nM, 33 nM, 28 nM and 20 nM, respectively.

1. Crebanine iv 5mg/kg can eonvert BaCl_2-induced arrhythmia into sinus rhythm in rats, and can significantly increase the tolerant dose of aconitine to produce ventrieular fibrillation(VF) and cardiac arrest (CA) in rata. 2. Crebanine can also decrease t

XK489 is a synthetic quinoxaline phenoxypropionic acid derivative with proapoptotic and antiproliferative activities. R(+)XK469 selectively inhibits topoisomerase II-beta, blocks activation of MEK MAPK signaling kinases, stimulates caspases, and upregulates p53-dependent proteins, including cyclins A and B1, thereby arresting cancer cells in the G2 M phase of the cell cycle. Both R(+) and S(-) isomers of this agent are cytotoxic, although the R-isomer is more potent.

Aurora kinase-IN-1, a potent aurora kinase inhibitor, modulates cell cycle progression and induces apoptosis by upregulating G1 cell cycle inhibitory proteins (including p21 and p27), elevating G1 progressive cyclin D1, and downregulating G1-to-S progressive cyclins, thereby arresting the cell cycle at the G1 S boundary. It stands as a promising lead compound for the development of chemotherapeutic agents.

Ailanthone (AIL) is a natural compound derived from the tree Ailanthus altissima and has anti-hepatocellular carcinoma (HCC) properties. It can induce G0/G1 phase cell cycle arrest by downregulating the expression of cyclins and CDKs, while upregulating the expression of p21 and p27. Additionally, Ailanthone is a potent androgen receptor (AR) inhibitor, capable of inhibiting both the full-length androgen receptor (IC50: 69 nM) and constitutively active splice variants (IC50: 309 nM).
