One hundred fifty-two methanol and water extracts of different parts of 71 plants commonly used in Sudanese traditional medicine were screened for their inhibitory effects on hepatitis C virus (HCV) protease (PR) using in vitro assay methods. Thirty-four extracts showed significant inhibitory
Effects of depetiolation on protein metabolism during senescence of detached betel (Piper betle L.) leaves have been studied. In normal petiolated leaves, the level of chlorophyll and proteins and extent of protein synthesis declined, while the protease activity registered manifold increase with the
OBJECTIVE
To isolate, fermentatively evaluate and identify black pepper (Piper nigrum L.)-associated bacteria for the microbial decortication of fresh ripened berries and dried black pepper for preparation of off-odour-free white pepper.
RESULTS
Among 45 bacterial isolates obtained from black
The complete genome of the Piper yellow mottle virus (PYMoV), a Badnavirus belonging to the family Caulimoviridae, was sequenced from three naturally infected hosts namely, black pepper, betelvine, and Indian long pepper. The genome length of the three virus strains (one from each of the three host
BACKGROUND
Piper betle, a tropical creeper plant belongs to the family Piperaceae. The leaves of this plant have been well known for their therapeutic, religious and ceremonial value in South and Southeast Asia. It has also been reported to possess several biological activities including
Urinary tract infections are the utmost common bacterial infections caused by Proteus mirabilis, Pseudomonas aeruginosa, Escherichia coli, and Serratia marcescens. These uropathogens resist the action of several antibiotics due to their ability to form biofilms. Most of these bacterial pathogens use
Piperine is an exact of the active phenolic component from Black pepper. It has been reported to have many biological activities including anti-oxidant, anti-inflammatory and anti-tumor effects. Intervertebral disc degeneration (IDD) is a degenerative disease closely relate to inflammation of
OBJECTIVE
The antitumoural properties of grandisin, a tetrahydrofuran neolignan from Piper solmsianum, were investigated by in-vitro and in-vivo assays using the Ehrlich ascites tumoural (EAT) model.
METHODS
Viability of the tumour cells was evaluated by Trypan blue exclusion and MTT methods, after
A new Piper nigrum cysteine proteinase inhibitor, PnCPI, belonging to group I of phytocystatins, with inhibitory activity against papain and growth of Fusarium solani f. sp. piperis, was isolated and characterized. Previous studies (de Souza et al. 2011) have identified a partial cDNA sequence of
