AS-IV

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.

Doxofylline (Doxophylline) is a methylxanthine derivative with the presence of a dioxolane group in position 7. As a drug used in the treatment of asthma, doxofylline has shown similar efficacy to theophylline but with significantly fewer side effects in animal and human studies.

Chlorin E6 (CE6) is a second-generation photosensitizer with antitumor activity when used in combination with irradiation. In a mouse model of implanted fibrosarcoma, Chlorin E6 (2.5-10 mg kg, i.v., 50-200 J cm2 irradiation) resulted in complete tumor disappearance after varying degrees of irradiation. Agents including Chlorin E6 were tested in a Phase I clinical study in patients with early superficial squamous cell carcinoma of bronchial origin with favorable results (40 mg m2, IV, 100 J cm2 laser irradiation). In a Phase II clinical trial in patients with early stage lung cancer, the same mode of administration resulted in a complete response in 82.9% of patients. Chlorin E6 has been investigated as a nanotechnology drug delivery tool.

Batatasin IV is identified from Dioscorea opposita which is a a type of homologous medicinal plant and is commonly used as food in daily life.

Arvenin IV is a natural product that can be used as a reference standard. The CAS number of Arvenin IV is 69312-48-7.

Isochromophilone IV is a natural product that can be used as a reference standard. The CAS number of Isochromophilone IV is 167173-90-2.

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

Lo Han Kuo extract is a high intensive sweetening agent with desirable health benefits, such as prevention of dental caries through specific antibacterial properties, no-calorie levels related to obesity, and a low glycemic index to help manage blood suga

Kaempferol 3-O-alpha-L-(2, 3-di-Z-p-coumaroyl) rhamnoside (compound 42), a flavonol extracted from Platanus Occidentalis, functions as an inhibitor of alpha-amylase and DPP IV [1].

Demethylbatatasin IV is a naturally occurring compound found in the yam species known as Dioscorea alata.
