The aim of the present investigation is to assess the sublethal toxicity of biologically synthesized silver nanoparticles (Ag NPs) in Indian major carp Labeo rohita. Ag NPs used in the study were synthesized by using AgNO3 with aqueous leaf extract of Piper nigrum. Median lethal concentration (LC50)
BACKGROUND
Piperine, a main component of Piper longum Linn. and Piper nigrum Linn., is a plant alkaloid with a long history of medicinal use. Piperine exhibits antidepressant, hepatoprotective, anti-metastatic, anti-thyroid, immunomodulatory, antitumor and anti-inflammatory activities, However its

Effect of piperine which is an alkaloid present in plants such as Piper nigrum and Piper longum on the production of nitric oxide (NO) and tumor necrosis factor-alpha (TNF-alpha) level was analyzed using in vitro as well as in vivo systems. The level of nitrite in the LPS stimulated Balb/C mice
Piperine, a main component of Piper longum Linn. and Piper nigrum Linn., is a plant alkaloid with a long history of medical use. Piperine exhibits anti-inflammatory activity; however, the underlying mechanism remains unknown. We examined the effects of piperine on lipopolysaccharide (LPS)-induced
Aging-related cholinergic dysfunction, extensive neuroinflammation and oxidative stress in brain are predominant pathogenic factors for dementia. In the present study, we aimed to evaluate the protective effects of piperine, an alkaloid nutrient component of Piper nigrum, against cognitive
Piperine is a phenolic component of black pepper (Piper nigrum) and long pepper (Piper longum), fruits used in traditional Asian medicine. Our previous study showed that piperine inhibits lipopolysaccharide-induced inflammatory responses. In this study, we investigated whether piperine reduces the
Thymoquinone (TQ) and piperine, the active ingredients in cumin (Nigella sativa) and black pepper (Piper longum), respectively, exhibit various bioactivities including anticancer effects. The aim of the present study is to investigate the antineoplastic activity of a combination of TQ and piperine
Extensive research within the past two decades has revealed that obesity, a major risk factor for type 2 diabetes, atherosclerosis, cancer, and other chronic diseases, is a proinflammatory disease. Several spices have been shown to exhibit activity against obesity through antioxidant and
