hypericum androsaemum/抗癌藥

We studied antitumor effects of peptide extracts from plants on slowly growing mammary adenocarcinoma in CBRB-Rb(8.17)1Iem mice used as a model of breast cancer in humans. The antitumor effect of a single injection of the test peptides was evaluated by the delay of the appearance and growth of

Hyperforin, a natural product of St. John's wort (Hypericum perforatum L.), has a number of pharmacological activities, including antidepressive and antibacterial properties. Furthermore, hyperforin has pronounced antitumor properties against different tumor cell lines, both in vitro and in vivo.

Hypericin, a naturally occurring pigment, is found in certain species of plants from the genus Hypericum, the most common of which is Saint John's Wort (Hypericum perforatum). Recent interest in hypericin is provoked by the discovery that it possesses extremely high toxicity towards certain viruses

Different antidepressant drugs are currently used for the treatment of depression in cancer patients, such as second-generation antidepressants and, recently, the extracts of Hypericum perforatum. These agents are susceptible to metabolically-based drug interactions with anticancer drugs. The aim of

OBJECTIVE To identify the pharmacologic interactions of oral anti-cancer drugs provided at an outpatient clinic. METHODS Anti-cancer drugs included in the Phamacotherapeutic Guideline of the Hospital were identified. A literature search was carried out on the pharmacologic interactions in MEDLINE®

Hypericum perforatum (St. John's wort) is well-established for its antidepressant activity throughout the world and also various other species within this genus are used in different folk medicines. Hyperforin of St. John's wort inhibited growth of cancer cell lines and the use of hypericin (another

In the present study we have investigated the in vitro antitumor effects of three benzopyrans, 6-isobutyryl-5,7-dimethoxy-2,2-dimethylbenzopyran (1), 7-hydroxy-6-isobutyryl-5-methoxy-2,2-dimethylbenzopyran (2) and 5-hydroxy-6-isobutyryl-7-methoxy-2,2-dimethylbenzopyran (3) isolated from Hypericum

The methanol extracts of the aerial parts of Hypericum mysorense and Hypericum patulum were tested for in vitro cytotoxicity on HEp-2, RD and Vero cell lines and antitumour activity using DLA and HEp-2 cell lines. The cell viability and morphological changes were assessed. Of these extracts,

A large number of plants belonging to the genus Hypericum and their phytoconstituents are known to possess potent anticancer nature. Earlier studies from our laboratories indicated a strong cytotoxic nature of the methanol extract of Hypericum hookerianum stem (MEHH). In the present study, the in

A large number of plants belonging to the Hypericum family are known to possess strong antitumor properties. The methanol extract of H. hookerianum Wight and Arnott stem (MEHH) exhibited potent in vitro cytotoxic activity against various cancerous cell lines. In the present study, the high

A series of dearomatized isoprenylated acylphloroglucinols derivatives, hyperhenols A-E (1-5), as well as seven known analogues (6-12), were characterized from Hypericum henryi. Their structures were determined by combination of NMR, ECD spectroscopy, and X-ray diffraction analysis. Compounds 1 and

BACKGROUND Cancer is an unnatural type of tissue growth in which the cells exhibit unrestrained division, leading to a progressive increase in the number of dividing cells. It is now the second largest cause of death in the world. The present study concerned antioxidant, anticancer and

The genus Hypericum is one of the most popular genera in both traditional medicine and scientific platform. This study is designed to provide conceptual insights on the biological potential and chemical characterization of H. salsugineum, which is endemic to Turkey. The qualitative and quantitative

OBJECTIVE Interest in the use of herbal products has grown dramatically in the Western world. Recent estimates suggest an overall prevalence for herbal preparation use of 13% to 63% among cancer patients. With the narrow therapeutic range associated with most anticancer drugs, there is an increasing
