Better preventive strategies are required to reduce ultraviolet (UV)-caused photodamage, the primary etiological factor for non-melanoma skin cancer (NMSC). Accordingly, here we examined the preventive efficacy of silibinin against UVB-induced photodamage using mouse epidermal JB6 cells and SKH1 hairless mouse epidermis. In JB6 cells, silibinin pretreatment protected against apoptosis and accel...

Recently, we reported that silibinin inhibits primary lung tumor growth and progression in mice and down-regulates inducible nitric oxide synthase (iNOS) expression in tumors; however, the mechanisms of silibinin action are largely not understood. Also, the activation of signaling pathways inducing various transcription factors are associated with lung carcinogenesis and their inhibition could ...

Sunscreens partially filter UVB and, therefore, could partially prevent skin cancer; however, efficient approaches are desired to effectively prevent photocarcinogenesis. It is hypothesized that nontoxic pharmacologically active natural compounds can increase photoprotective effects. Our completed studies suggest that silibinin, a bioactive phytochemical, strongly prevents photocarcinogenesis; ...

objective: this study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (hcc) cell line (hepg2). materials and methods: in this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with hepes buffer and sonication at 60% amplitu...

Silibinin, an active constituent of silymarin possesses several medicinal properties. Although, the poor water solubility and less bioavailability restrict clinical utility silibinin, complex silibinin phosphatidylcholine manifested outstanding biological activities in vivo. Thereby, was prepared with (1:2, w/w) for better therapeutic efficacy their physicochemical properties were analyzed. The...

− This study was designed to investigate the effects of silibinin on the pharmacokinetics of carvedilol after oral administration of carvedilol in rats. Carvedilol was administered orally (3 mg/kg) with oral silibinin (0.3, 1.5 or 6 mg/ kg) and intravenously (1 mg/kg) to rats. The effects of silibinin on P-glycoprotein (P-gp) and cytochrome P450 (CYP) 2C9 and CYP2D6 activity were also evaluated...

BACKGROUND AND PURPOSE Accumulated evidence suggests that oxidative stress is involved in amyloid beta (Abeta)-induced cognitive dysfunction. Silibinin (silybin), a flavonoid derived from the herb milk thistle (Silybum marianum), has been shown to have antioxidative properties; however, it remains unclear whether silibinin improves Abeta-induced neurotoxicity. In the present study, we examined ...

Objective: The present study was aimed to develop a high performance liquid chromatographic method for simultaneous estimation of curcumin and silibinin and to implement the developed method for the estimation of curcumin and silibinin encapsulated in polymeric nanoparticles. Methods: Method development for simultaneous estimation of curcumin and silibinin was performed using various solvent, b...

The acute and cumulative dose-related toxicity and drug resistance, mediated via nuclear factor B (NF B), of anthracycline anticancer drugs pose a major problem in cancer chemotherapy. Here, we report that oral silibinin (a flavanone) suppresses human non–small-cell lung carcinoma A549 xenograft growth (P 0.003) and enhances the therapeutic response (P < 0.05) of doxorubicin in athymic BALB/c n...

OBJECTIVE This study aimed to evaluate a co-encapsulated pegylated nano-liposome system based on two herbal anti-tumor drugs, silibinin and glycyrrhizic acid, for delivery to a hepatocellular carcinoma (HCC) cell line (HepG2). MATERIALS AND METHODS In this experimental study, co-encapsulated nano-liposomes by the thin layer film hydration method with HEPES buffer and sonication at 60% amplitu...
