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.
Calycosin (Cyclosin) acts as a selective estrogen receptor modulator. Calycosin induces apoptosis in human ovarian cancer SKOV3 cells by activating caspases and Bcl-2 family proteins. Calycosin suppresses breast cancer cell growth via ERβ-dependent regulation of IGF-1R, p38 MAPK and PI3K/Akt pathways. Calycosin has antineoplastic effects against osteosarcoma through inducing apoptosis showing in vitro and in vivo investigations. Calycosin was shown to induce angiogenesis in human umbilical vein endothelial cell cultures (HUVEC) in vitro. Calycosin may be an effective skin-lightening agent that regulates the expression of melanogenic enzymes. Calycosin exhibited tyrosinase inhibitory activity with an IC(50) value of 38.4 microM.
Astragaloside may protect against brain contusion and neuronal apoptosis after TBI by attenuating microglia activation in male rats. Astragalosides-induced apoptosis in NB4 cells may be associated with down-regulation of the expression of BCL-2 and NF-κB,
Astragaloside III has cardioprotective effects as well as causing improvement in cognitive function. It can be used in the prevention of cardio-cerebral vascular diseases. It also is antioxidant.
Astragaloside II (Astrasieversianin VIII) is an effective MDR reversal agent and may be a potential adjunctive agent for hepatic cancer chemotherapy. Astragaloside II also induces osteogenic activities, differentiation, proliferation, and mineralization, through the bone morphogenetic protein-2/MAPK and Smad1/5/8 pathways.
Glycerol Tridecanoate is an orally active precursor (DA precursor) of caprylic acid that can be hydrolyzed to caprylic acid. It is a major component of medium chain triglycerides (MCT) and has antiandrogenic and antihyperglycemic properties. It can be used as an additive in food, pharmaceuticals and cosmetics.
Methylnissolin is a natural product isolated from Astragalus membranaceus that inhibits platelet-derived growth factor (PDGF)-BB-induced cell proliferation with an IC50 of 10 μM. It inhibits PDGF-BB-induced vascular smooth muscle cell proliferation by inhibiting the ERK1/2 MAP kinase cascade. It also inhibits PDGF-BB-induced phosphorylation of extracellular signal-regulated kinase 1/2 (ERIC1/2) mitogen-activated protein (MAP) kinases and has antibacterial and anticancer effects.
Isoastragaloside II (Astrasieversianin VII) is a derivative Astragaloside I, an ingredient in Astragalus membranaceus which is reported to have osteogenic properties.
Astragaloside I (Cyclosieversioside B) is a natural product isolated from Astragalus membranaceus. It can stimulate osteoblast differentiation through the Wnt/β-catenin signaling pathway and can be used to study osteogenic activity.
Calycosin-7-O-β-D-glucoside (calycosin-7-O-beta-D-glucopyranoside) possesses a protective effect on rat hepatocytes, an inhibitory effect on COX-2 activity. Calycosin 7-O-β-D-glucoside has antimicrobial activity. Calycosin 7-O-β-D-glucoside is a promising anti-HIV agent. It shows scavenging activity to DPPH radicals and superoxide anion. Calycosin 7-O-β-D-glucopyranoside possesses an alleviating effect on osteoarthritis and can increase the fluidity of brain cell membrane in ischemia-reperfusion rats.
Cholesteryl linoleate is the major cholesteryl ester in LDL and atherosclerotic lesions. It is present in LDL as a cholesteryl ester that is oxidized to form cholesteryl linoleate hydroperoxides using LDL receptor-associated proteins that are transferred to the plasma membranes of macrophages and CHO cells expressing 15-lipoxygenase.
Astramembrangenin (Cycloastragenol (Astramembrangenin)) is a triterpenoid saponin compound and a hydrolysis product of the main active ingredient in Astragalus membranaceus. Cycloastragenol (CAG) may have a novel therapeutic role in depression
