The polysaccharide fraction from the root of Angelica acutiloba Kitagawa showed a potent antitumor activity against ascitic form of Sarcoma-180, IMC carcinoma, and Meth A fibrosarcoma as well as the solid form of MM-46 tumor. An active polysaccharide, AR-4E-2, was purified by precipitation with

BACKGROUND Despite diagnostic and therapeutic advancements, the burden of cancer is still increasing worldwide. Toxicity of current chemotherapeutics to normal cells and their resistance to tumor cells highlights the urgent need for new drugs with minimal adverse side effects. The use of natural

The Kampo-prescription, Shi-un-kou, and its constituent crude drugs [Lithospermum erythrorhizon (1), Macrotomia euchroma (2) and Angelica acutiloba (3)] were assayed for their inhibitory effects on Epstein-Barr virus activation induced by the tumor promoter, 12-O-tetradecanoylphorbol-13-acetate

The antimutagenic activity of Angelica archangelica L. aqueous and alcohol extracts of thio-TEPA against mutagenicity was examined by the micronucleus test in murine bone marrow cells. The reduction of Thio-TEPA's mutagenic activity was more profound when the extracts were injected 2 hours before

The antimutagenic activity Angelica archangelica L. water and alcohol extracts thio-tepa against mutagenicity was investigated by the micronucleus test in mouse bone marrow and peripheral blood cells. The reduction of thio-tepa mutagenic activity was more prominent when the extracts were injected

BACKGROUND The purpose of this study was to examine the effect of a leaf extract from A. archangelica on the growth of Crl mouse breast cancer cells in vitro and in vivo. METHODS The antiproliferative activity of the extract was measured by 3H-thymidine uptake in the Crl cells in vitro. Twenty mice

We recently demonstrated that two chalcones isolated from Angelica keiskei roots have anti-tumor and anti-metastatic activities through the inhibition of tumor-induced angiogenesis, but the anti-tumor substances of Angelica japonica roots are unknown. We attempted to clarify the anti-tumor action

We prepared hybrids consisting of Angelica gigas Nakai (AGN) root or flower extract and layered double hydroxide (LDH) for potential anticancer nanomedicine, as decursin species (DS) in AGN are known to have anticancer activity. Dimethylsulfoxide solvent was determined hybridization reaction media,

Ninety-five extracts prepared from 14 kinds of Umbelliferous materials were studied to determine their effects on tumor-promoter-induced phenomena in vitro. Of the materials, 5 Chinese crude drugs, two Bai-Hua Qian-Hu classified as Q-I and Q-II types, the root of Peucedanum praeruptorum Dunn.,

Despite advances in medical treatments for colon cancer, it remains one of the leading causes of cancer-related mortality among men. Thus, more efficacious treatment strategies for colon cancer are needed. Imperatorin is one of the major ingredients present in the root of Angelica dahurica, and has

We have reported that a 10-herbal traditional formula containing Korean Angelica gigas Nakai (AGN) exerts potent anti-cancer efficacy and identified decursin and decursinol angelate (DA) from AGN as novel anti-androgens. Here, we determined whether AGN would exert in vivo anti-cancer activity and

BACKGROUND The polysaccharide component of Angelica gigas induces immuno-stimulatory effects on innate immune cells. However, it is unclear whether A. gigas' adjuvant activity on the immune system can elicit anti-cancer responses. METHODS A water-soluble immuno-stimulatory component of A. gigas was

We isolated a coumarin compound decursin (C(19)H(20)O(5); molecular weight 328) from Korean angelica (Angelica gigas) root and characterized it by spectroscopy. Here, for the first time, we observed that decursin (25-100 micromol/L) treatment for 24 to 96 hours strongly inhibits growth and induces

Korean Angelica gigas Nakai (AGN) is a major medicinal herb used in Asian countries such as Korea and China. Traditionally, its dried root has been used to treat anemia, pain, infection and articular rheumatism in Korea, most often through boiling in water to prepare the dosage forms. The

The in vivo anti-tumor activities of decursinol angelate (1) and decursin (2) isolated from the roots of Angelica gigas were investigated. These two compounds, when administered consecutively for 9 days at 50 and 100 mg/kg i.p. in mice, caused a significant increase in the life span and a
