• 説明

  Cycloastragenol is the genuine sapogenin of astragaloside IV, a major bioactive constituent of the Chineseherbal medicine Astragali Radix (Huang-Qi). Astragaloside IV exhibits various pharmacological properties, suchas anti-viral, anti-inflammatory, anti-aging,and antioxidant activities.Cycloastragenol is a telomerase activator,which delays the onset of cellularaging. Thus, cycloastragenol is considered as a newgeneration of anti-aging agent.

• 使用

  Cycloastragenol, a saponin and aglycone found in Astragalus, is a natural triterpenoid. It has anti-aging properties and can also act as an adjuvant therapy for cancer by enhancing the effectiveness of anti-cancer drugs, reducing their toxicity, and preventing/treating leukopenia caused by these treatments.

• 定義

  ChEBI: Cycloastragenol is a sapogenin that is the aglycone derivative of astragaloside IV, a major saponin extracted from the root of Astragalus membranaceus. It has a role as a metabolite. It is a sapogenin, a pentacyclic triterpenoid, a tetrol and a member of oxolanes. It derives from a hydride of a 5alpha-gonane.

• 利点

  Cycloastragenol has a steroidal skeleton of tetracyclic triterpene and possess diverse pharmacological activities such as anti-aging, anti-inflammatory, anti-fibrosis, pro-wound healing, liver protection and endothelial protection.

• 生物活性

  Cycloastragenol(78574-94-4), a natural tetracyclic triterpenoid, was first identified when screening Astragalus membranaceus extracts for active ingredients with antiaging properties. IC50 value:Target:In vitro: In the study of Cycloastragenolon the treatment of degenerative diseases, the result showed that first-pass intestinal metabolism of cycloastragenol might occur upon passage through the intestinal epithelium. Cycloastragenol underwent extensive metabolism in rat and human liver microsomes with only 17.4% and 8.2%, respectively, of the starting amount of Cycloastragenol remaining after 30 min of incubation [1]. The present study demonstrates that cycloastragenol stimulates telomerase activity and cell proliferation in human neonatal keratinocytes. In particular, cycloastragenol promotes scratch wound closure of human neonatal keratinocyte monolayers in vitro [3]. In vivo: Rats were treated with Cycloastragenol (40 mg·kg- 1·d- 1) for 7 days to induce hepatic microsomal enzyme. The result showed that compared with the control, cycloastragenol obviously activated CYP2E1, and remarkably inhibited CYP3A4 [2].

• Biochem/physiol Actions

  Cycloastragenol is used as a nutraceutical (e.g. TAT2) and seems to moderately increase the telomerase activity and proliferative capacity of both CD4 and CD8 T-cells. Cycloastragenol possesses antiviral, antimicrobial, anti-inflammatory, anti-hepatotoxic, anti-leukemia, antitumor and antinociceptive activity. It also acts as an immunomodulator.

• 副作用

  Cycloastragenol is a telomerase activator. Fortunately, the experimental results did not show an increased risk of cancer and other adverse effects.

• Dosage

  As a dietary supplement, take one 100mg capsule of Cycloastragenol daily.
