BACKGROUND Chemotherapy of cholangiocarcinoma (CCA), a devastating cancer with increasing worldwide incidence and mortality rates, is largely ineffective. The discovery and development of effective chemotherapeutics is urgently needed. METHODS The study aimed at evaluating anticancer activities,

OBJECTIVE This study screened for anthelmintic and/or antitumour bioactive compounds from Thai indigenous plants and evaluated effectiveness against three different worm species and two cancer cell lines. METHODS Methylene chloride and methanol extracts of 32 plant species were screened for in vitro

Scientists are constantly searching for phytochemical compounds with anti-cancer activity. In this study, activity of plant extract NPB001-05 from Piper betle was tested on human chronic myelogenous leukemia (CML) xenograft models. NPB001-05 was active when dosed orally (500 mg/kg) once or twice a

Kava is a beverage made from the ground roots of the plant Piper Methysticum. Active compounds of Kava have previously been demonstrated to exert an antiproliferative effect through cell cycle arrest and promotion of apoptosis. Our aim was to investigate the in vitro effects of the main constituents

Since antiquity, Piper betel Linn (betel vine; family Piperaceae) has been an important medicinal agent in the various traditional and folk systems of medicine in Southeast Asia countries. The leaves are the most valued plant part and in the past were routinely used as a chewing agent to prevent

Despite the advances in anticancer drug discovery field, the worldwide cancer incidence is remarkable, highlighting the need for new therapies focusing on both cancer cell and its microenvironment. The tumor microenvironment offers multiple targets for cancer therapy, including inflammation.

Tumour reducing activity of extracts of eight commonly used spices in India were studied in mice transplanted intraperitoneally with Ehrlich ascites tumour. Oral administration of extracts of black pepper, asafoetida, pippali and garlic could increase the percentage of life span in these mice by

BACKGROUND Piper sarmentosum, locally known as kaduk is belonging to the family of Piperaceae. It is our interest to evaluate their effect on human hepatoma cell line (HepG2) for the potential of anticarcinogenic activity. RESULTS The anticarcinogenic activity of an ethanolic extract from Piper

(-)-Cubebin, isolated from the seeds of Piper cubeba, and its five different types of derivatives (a total of 17), with varying functionalities, were tested for their in vitro anticancer activity against six human cancer cell lines (A549, K562, SiHa, KB, HCT116 and HT29) using MTT assay. Cubebin as

Piper nigrum (P. nigrum) is commonly used in traditional medicine. This current study aimed to investigate the anticancer and cancer preventive activity of a piperine-free P. nigrum extract (PFPE) against breast cancer cells and N-nitrosomethylurea (NMU)-induced mammary tumorigenesis in rats. The
