Umbelliprenin is a sesquiterpene coumarin with vitro anti-carcinogenic activities. The aim of this study was to investigate the antitumor effects of umbelliprenin in animal models of colorectal cancer. The cytotoxic effects of umbelliprenin were explored on CT26 and L929by MTT assay. In this study, colorectal tumors developed in mice by intradermal injection of CT26 cell line. Tumor size, serum...

Objective: A number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. It has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (NO) production. These data suggest that the cytotoxic effect of saffron extra...

Berberine, an isoquinoline alkaloid isolated from several traditional Chinese herbal medicines (TCM), exhibits a strong antimicrobial activity in the treatment of diarrhea. However, it causes human as well as animal toxicity from heavy dosage. The present study was conducted to investigate the cytotoxicity of berberine and its possible trigger mechanisms resulting in cell cycle arrest, DNA dama...

Methods: Three concentrations of carbamide peroxide (10%, 16%, and 22%) used in home bleaching techniques were evaluated regarding their cytotoxic effect on gingival tissues. The materials were divided into three groups as follows: Group C10 (White Gold Home 10%, Dentsply), Group C16 (White Gold Home 16%, Dentsply, and Group C22 (Nite White 22%, ACP Discus Dental). The cytotoxicity essay was ca...

In this study, we present initial data for the potential anti-cancer effects of standardized Bulgarian Petasites hybridus root extract against breast cancer cells. The results showed that Butterbur (BE) caused a dose-dependent selective reduction in viability with concomitant increase apoptosis human cells after 72 h treatment. We found highest cytotoxicity BE to MDA-MB-231 (IC50 – 520 ?g/mL), ...

Autophagy has diverse biological functions and is involved in many biological processes. The L929 cell death induced by the pan-caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp-(OMe)-fluoromethyl ketone (zVAD) was shown to be an autophagy-mediated death for which RIP1 and RIP3 were both required. It was also reported that zVAD can induce a small amount of TNF production, which was shown to be re...

Objective: To investigate the in vitro antioxidant, antimicrobial, anticancer, and wound healing properties of leaf extracts Acanthus ilicifolius.
 Methods: ilicifolius leaves were dried prepared using different solvents cold extraction method. The preliminary phytochemical analysis quantitative methods carried out standard procedures. In antioxidant activity was evaluated DPPH assay. Disc...
