BACKGROUND
Alpinia scabra, locally known as 'Lengkuas raya', is an aromatic, perennial and rhizomatous herb from the family Zingiberaceae. It is a wild species which grows largely on mountains at moderate elevations in Peninsular Malaysia, but it can also survive in the lowlands like in the states
Eight ethanolic extracts of indigenous Taiwanese plants of the genus Alpinia were tested for tumor cytotoxicity against AGS, Hep G2, HeLa, KB, and HL-60 cells. Among the 50 % and 95 % EtOH extracts of eight Alpinia species, the cytotoxic effects of Alpinia intermedia leaves were the strongest. When
The purpose of this study was to evaluate the enhancing potency of tectochrysin, a flavonoid isolated from Alpinia oxyphylla Miquel by combining cetuximab, an anti-EGFR monoclonal antibody, on human colon cancer cell growth through further inhibition of EGFR pathway. HCT116 and SW480 colon cancer
Vascular endothelial growth factor (VEGF) is a glycoprotein vital to the regulation of vascular endothelial cells proliferation, migration and angiogenesis. The expression of VEGF is required for the formation of new blood vessels critical in supplying oxygen and nutrition in the course of
Alpinia pricei has been shown to induce apoptosis in human squamous carcinoma (KB) cells. In this study, we report the effectiveness of the ethanol (70%) extracts of A. pricei rhizome (AP extracts) in terms of tumor regression as determined using both in vitro cell culture and in vivo athymic nude
BACKGROUND
Alpinia nantoensis (Zingiberaceae) is an aromatic plant endemic to Taiwan, which is used as food flavoring and traditional herbal medicine. The biological activities of compounds isolated from this plant are rarely investigated.
OBJECTIVE
The present study was aimed to investigate the
Cancer therapeutic agents that are safe, effective and affordable are urgently needed. We describe that 1'-acetoxychavicol acetate (ACA), a component of Siamese ginger (Languas galanga), can suppress prostate tumor growth by largely abrogating angiogenesis. ACA suppressed vascular endothelial growth
There have been considerable efforts to search for naturally occurring substances for the intervention of carcinogenesis. Many components from dietary or medicinal plants have been identified that possess substantial chemopreventive properties. An example is curcumin (Curcuma longa Linn.,
BACKGROUND/AIM
Plants play an important role in anti-
cancer drug discovery, therefore, the current study aimed to evaluate the biological activity of
Alpinia zerumbet (
A. zerumbet) flowers.
METHODS
The phytochemical and biological criteria of
1'-(S)-1'-Acetoxychavicol acetate (ACA) isolated from the Malaysian ethno-medicinal plant Alpinia conchigera Griff. was investigated for its potential as an anticancer drug. In this communication, we describe the cytotoxic and apoptotic properties of ACA on five human tumour cell lines. Data from
Medicinal plants containing active natural compounds have been used as an alternative treatment for cancer patients in many parts of the world especially in Asia (Itharat et al. 2004). In this report, we describe the cytotoxic and apoptotic properties of 1'S-1'-acetoxyeugenol acetate (AEA), an
Signal transducer and activator of transcription 3 (STAT3) is implicated breast cancer metastasis and represents a potential target for developing new anti-tumor metastasis drugs. The purpose of this study is to investigate whether the natural agent 1'-acetoxychavicol acetate (ACA), derived from the
This study was carried out to isolate ingredients from the seeds of a Chinese spice (Alpinia galangal) and to evaluate their cytotoxic activity on cancer cell lines. Isolation and purification of the phytochemical constituents were conducted using silica gel, Sephadex LH-20 and ODS columns. After
From a viewpoint of cancer chemoprevention, possible anti-tumour promoting properties of daily food items and some of their active constituents have been investigated by a convenient in-vitro assay, the Epstein-Barr virus (EBV) activation test. In a screening test for the inhibitory activity toward
In recent years, there have been considerable efforts to search for naturally occurring substances for intervention of carcinogenesis. Many components from medicinal or dietary plants have been identified to possess potential chemopreventive properties. For instance, curcumin, a yellow colouring
