OBJECTIVE
To study the chemical constituents from the crop pathogenic fungus active fraction of Wisteria sinensis tumor.
METHODS
The chemical constituents were extracted of different concentrations and isolated by silica gel and Sephadex LH-20 column. The chemical structures of components were
We previously found that dibutyl phthalate (DBP) had a pharmacological activity in eliminating tumor cells and could be used as a purging agent in autologous bone marrow transplantation. In this study, we show that DBP can induce apoptosis in MO7e and U937 leukemia cell lines. Treatment of these
The effects of dimethyl phthalate, diethyl phthalate, diisobutyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, di-2-ethylhexyl phthalate were investigated on human prostate cancer cell lines DU145 and PC3 in vitro.
Standards of dimethyl phthalate, diethyl phthalate, di-isobutyl phthalate,
This study is the first to demonstrate that parathyroid hormone-related protein (PTHrP), produced by human breast cancer cells after exposure to phthalate esters, contributes to bone metastasis by increasing osteoclastogenesis. This is also the first to reveal that obtusifolin reverses phthalate
Objective: Despite advanced treatment options available, drug resistance develops in breast cancer (BC) patientsrequiring novel effective drugs. Stylissa carteri, a marine sponge predominantly living in Indonesia territories, hasnot been extensively studied as anti-cancer. Therefore, this study
A new sesquiterpenoid quinone, Acyl hibiscone B (1), together with five known compounds, (R)-lasiodiplodin (2), (R)-de-O-methyllasiodiplodin, (3) dibutyl phthalate (4), (R)-9-phenylnonan-2-ol (5) and hibiscone B (6), was obtained from the stem tuber of Abelmoschus sagittifolius. The structure of
Over the last decade, the consumption of water bottled in polyethylene terephthalate (PET) has considerably increased, raising concerns over water quality and packaged materials. This study aims to investigate the levels of the anti-androgenic phthalates including bis-(2-ethylhexyl) phthalate
BACKGROUND
Carcinogenesis in the larynx and oropharynx is often associated with excessive exposure to tobacco smoke and alcohol. However, attention is increasingly being focused on genetically determined mutagen sensitivities and on the mutagenic impact of xenobiotics. The purpose of this study was
A variety of so-called innocuous chemicals can have insidious and long lasting effects on the developing male reproductive system. Developmental exposures of male rabbits to common industrial contaminants in drinking water (a mixture of arsenic, chromium, lead, benzene, chloroform, phenol, and
Due to its ability to cross blood brain barrier and placenta, dibutyl phthalate (di-n-butyl phthalate, DBP) is expected to cause severe side effects to the central nervous system of animals and humans. A little data is available about the potential DBP neurotoxicity; therefore, this work was
The phthalates are ubiquitous industrial plasticizers and include agents such as di(2-ethylhexyl) phthalate (DEHP), dibutyl phthalate (DBP), and butyl benzyl phthalate (BBP), which are classified as endocrine disruptors because of their anti-androgenic or pro-estrogenic effects. A recent study
BACKGROUND
Typhonium blumei Nicolson & Sivadasan is a traditional Chinese medicinal herb endowing with detumescence, detoxification, anti-inflammation activities, and has been used as a folk prescription on anticancer in Taiwan.
OBJECTIVE
The purpose of this study is to investigate the inhibitory
Despite the fact that the estrogenic effects of bisphenols were first described 80 years ago, recent data about its potential negative impact on birth outcome parameters raises a strong rationale to investigate further. The adverse health effects of plastics recommend to measure the impacts of
Environmental exposure to phthalates during intrauterine development might increase susceptibility to neoplasms in reproductive organs such as the prostate. Although studies have suggested an increase in prostatic lesions in adult animals submitted to perinatal exposure to phthalates, the molecular
During the development of an individual from a single cell to prenatal stages to adolescence to adulthood and through the complete life span, humans are exposed to countless environmental and stochastic factors, including estrogenic endocrine disrupting chemicals. Brain cells and neural circuits are
