Astragaloside IV (AS-IV), an active component isolated from Astragalus membranaceus, suppresses the activation of ERK1/2 and JNK, and downregulates matrix metalloproteases (MMP)-2, (MMP)-9 in MDA-MB-231 breast cancer cells. Astragaloside IV is a bioactive saponin first isolated from the dried plant roots of the genus Astragalus, which is used in traditional Chinese medicine.1 It dose-dependently inhibits human adenovirus type 3 (HAdV-3) in A549 cells (IC50 = 23 μM; LC50 = 865 μM).It inhibits replication of HAdV-3 and decreases HAdV-3-induced apoptosis. It has diverse protective effects for the cardiovascular, immune, digestive, and nervous systems. In particular, it reduces myocardial infarct size in dogs when administered prior to coronary ligation and reduces reperfusion arrhythmias in isolated rat hearts.

Y-27632 dihydrochloride (Y-27632 2HCl) is an orally potent, ATP-competitive inhibitor of ROCK-I and ROCK-II. Y-27632 dihydrochloride also inhibits isolation-induced apoptosis in mouse prostate stem or progenitor cells.

Thiazovivin, a ROCK inhibitor (IC50: 0.5 μM), increases the survival rate of hESC.

Y-27632 is an orally potent, ATP-competitive inhibitor of ROCK-I and ROCK-II. Y-27632 also inhibits isolation-induced apoptosis in mouse prostate stem or progenitor cells.

Notoginsenoside R1 (Sanchinoside R1) has been shown to exhibit antioxidant, antiapoptotic, anti-inflammatory, and immune-stimulatory properties.

Honokiol (NSC-293100) is the active principle of magnolia extract. It inhibits the activation of Akt and enhances the phosphorylation of ERK1/ERK2.

RKI-1447 is a potent inhibitor of ROCK1 and ROCK2. It has anti-invasive and antitumor activities.

Selumetinib (AZD6244) is a MEK1/2 inhibitor that inhibits MEK1 (IC50=14 nM) with potent selectivity and is non-ATP-competitive. Selumetinib has antitumor activity and is used for the treatment of neurofibromatosis type 1 (NF1).
