Synthesis, characterization and anti-breast cancer potential of an incensole acetate nanoemulsion from Catharanthus roseus essential oil; in silico, in vitro, and in vivo study.

The characteristics of phytocompounds and essential oils have undergone extensive research in the medical and pharmaceutical sectors due to their extensive usage. In spite of the fact that these molecules are widely used, terpenes, terpenoids, and their derivatives have not yet been well characterized. This study intends to evaluate the prospective activity of incensole acetate (IA), a compound identified and isolated from Catharanthus roseus essential oil by GC/MS analysis and column chromatography, and to analyze the anticancer effect of an IA biosynthesized nanoemulsion against breast cancer. The in silico activity of IA against breast cancer targets was observed by molecular docking, ADMET assessment and molecular dynamics simulations. The IA-mediated nanoformulation exhibited cytotoxicity against breast cancer cell lines at an effective concentration when analyzed by MTT and crystal violet assay. The increased interleukin serum indicators were significantly improved as a result of nanoemulsion treatment in a DMBA-induced rat model. In addition, the anticancer properties of IA biosynthesized nanoemulsion are supported due to their potential effects on biochemical parameters, oxidative stress markers, proinflammatory cytokines, and upon tumor growth profiling in cancer-induced rats.

Vitamin C supplementation ameliorates liver function profile and antiviral treatment response in Hepatitis C patients.

An imbalance between oxidative stress and antioxidative defence mediates a variety of diseases pathogenesis. The present study aims to assess the possible outcome of supplementation of oral vitamin-C (VC), an antioxidant, in Viral Hepatitis C (HCV) treatment as an adjuvant therapy. 200 HCV-patients were selected, 100 were given Vitamin-C (1000 mg/day) along with anti HCV treatment (sofosbuvir plus daclatasvir) while the other 100 took only anti-HCV treatment for 4weeks. The serum ascorbic acid (Vitamin-C) levels and functions of the liver were tested before and after the VC supplementation. HCV patients with relatively low serum ascorbic acid showed significant improvement after the intake of vitamin C. After 4 weeks of treatment, AST, ALP, albumin, and total, direct and indirect bilirubin were improved significantly in the VC group; whereas only ALT and indirect bilirubin were improved in both groups when associated with the control subjects. Comparing the two treatment groups at 4weeks; more effective and significant improvement was observed in ALT (p<0.01), AST (p<0.001), direct (p<0.01) and indirect bilirubin (p<0.001), total proteins (p<0.001) and albumin (p<0.05) in patients with VC supplementation on anti-viral treatment compared to only anti-viral treatment group. Thus, VC supplementation improves the antiviral therapy outcome by bestowing a beneficial effect in minimizing liver damage in HCV cases.
