benzopyrone/悪性腫瘍

We report the modulatory effect of coumarin (1,2-benzopyrone) on potassium bromate (KBrO(3)) mediated nephrotoxicity in Wistar rats. KBrO(3) (125 mg/kg body weight, i.p.) enhances gamma-glutamyl transpeptidase, renal lipid peroxidation, xanthine oxidase and hydrogen peroxide (H(2)O(2)) generation

In this study, we report the modulatory effect of coumarin (1,2-benzopyrone) on Ferric nitrilotriacetate (Fe-NTA) induced renal oxidative stress and tumor promotion response in rats. Fe-NTA (9 mg Fe/kg body weight, intraperitoneally) enhances renal lipid peroxidation, xanthine oxidase,

Coumarin is a naturally occurring sweet-smelling benzopyrone that may be extracted from plants or synthesized for commercial uses. Its uses include as a flavoring agent, fragrance enhancer, and odor-masking additive. We reviewed and evaluated the scientific evidence on the carcinogenicity of

Coumarins are a member of the benzopyrone family of compounds with diverse and interesting pharmacological properties. In the present study, we report the in vitro cytotoxicity evaluation of 7,8-Diacetoxy-3-arylcoumarin derivatives (5a-h) in human prostate (PC-3) and breast (MDA-MB-231) cancer cell

Cancer is the second major cause of mortality worldwide, losing only to cardiovascular disease. Nowadays, around 50% of antineoplastic drugs were discovered and isolated by indications of plants in folk medicine. In Brazilian flora there are many species of plants which have great therapeutic

Curcumin has been well studied for its anti-oxidant, anti-inflammatory, and anti-cancer action. Its potential as a therapy is limited due to its low bioavailability and rapid metabolism. To overcome these challenges, investigators are developing curcumin analogs, nanoparticle formulations, and

We have demonstrated in a pilot study that the combination of coumarin (1,2-benzopyrone) and cimetidine is capable of producing objective antitumor responses in patients with advanced renal cell carcinoma. In a previous study, we used monoclonal antibody labeling techniques to monitor peripheral

Forty-five patients with metastatic renal cell carcinoma were treated with coumarin (1,2-benzopyrone) and cimetidine. Patients received coumarin, 100 mg orally daily; cimetidine administration, 300 mg orally four times daily, was initiated on day 15 of therapy, and treatment with both drugs was

Chronic inflammation is known to facilitate carcinogenic transformation in various tissues. 5-iodo-6-amino-1,2-benzopyrone (INH2BP), a novel inhibitor of the nuclear enzyme poly(ADP-ribose) polymerase (pADPRT) has recently been shown to regulate a variety of cellular signal transduction pathways and

Structurally diverse compounds can confer resistance to aflatoxin B1 (AFB1) hepatocarcinogenesis in the rat. Treatment with either phytochemicals [benzyl isothiocyanate, coumarin (CMRN), or indole-3-carbinol] or synthetic antioxidants and other drugs (butylated hydroxyanisole, diethyl maleate,

INH2BP (5-iodo-6-amino-1,2-benzopyrone), a poly-ADP ribose polymerase inhibitor, has been shown to possess anti-cancer, anti-viral, and anti-inflammation properties. The aim of this study was to investigate the protective effect of INH2BP against oxidative stress-induced apoptosis in H9c2

The Benzopyrones are a group of compounds whose members include coumarins and flavonoids. Dietary exposure to benzopyrones is quite significant, as these compounds are found in vegetables, fruit, seeds, nuts, coffee, tea and wine. It is estimated that the average western diet contains approximately

Coumarin class of organic compounds consists of 1,2-benzopyrone ring system as a basic parent scaffold. These benzopyrones are subdivided into alpha-benzopyrones and gammabenzopyrones; with coumarin class of compounds belonging to alpha-benzopyrones. Since the last few years, coumarins were

Sanggenon C is a well-known, major active agent of the flavonoid derivative of benzopyrone with valuable biological properties, including anticancer, anti-inflammatory, antimicrobial, antiviral, antithrombotic, and immune-modulatory activities. In this study, we investigated the molecular mechanisms

Angiogenesis, the process of formation and recruitment of new blood vessels from pre-existing vessels, plays an important role in the development of cancer. Therefore, the use of antiangiogenic agents is one of the most critical strategies for the treatment of cancer. In addition, the complexity of
