Picrosides, the terpenoids synthesized by Picrorhiza kurroa, have ample usage in medicine. Identification of the regulatory enzymes involved in picroside biosynthesis needs to be explored for improving the level of these secondary metabolites. Current efforts are based on the analysis of secondary metabolism in picroside biosynthesis but its interpretation(More)
Urinary stone disease is an ailment that has afflicted human kind for many centuries. Nephrolithiasis is a significant clinical problem in everyday practice with a subsequent burden for the health system. Nephrolithiasis remains a chronic disease and our fundamental understanding of the pathogenesis of stones as well as their prevention and cure still(More)
This paper reports the optimum conditions for the extraction of picrosides from Picrorhiza kurroa using response surface methodology (RSM). A central composite design (CCD) was used to investigate the effects of four independent variables, namely methanol concentration (%), solid-to-liquid ratio (g/mL), incubation time (min) and temperature (°C) on the(More)
Picroside-I (P-I) is a member of the iridoid glycosides family of natural products, which are used to treat liver disorders. The growing medicinal need for this benign compound has stimulated the present study to identify genes important for the biosynthesis of P-I. In this study, molecular screens have been generated using gene expression patterns obtained(More)
PURPOSE Kidney stone is one of the most prevalent diseases worldwide. Calcium oxalate (CaOx) has been shown to be the main component of the majority of stones formed in the urinary system of the patients with urolithiasis. The present study evaluates the antilithiatic properties of Terminalia chebula commonly called as ″harad ″ which is often used in(More)
Picrorhiza genus is emerging as an important paradigm for herbal drug formulations due to its versatile iridoid glycosides exhibition and robustness in the treatment of diverse infections including hepatic amoebiasis, cancer, malaria, ulcerative colitis and cerebral ischemia reperfusion injury. Owing to the superiority of these bioactivities, iridoid(More)
The purpose of this current study was to justify the incorporation of complementary and alternate medicine (CAM) in current cancer treatments. The major drawback of anticancer drugs is their nonselective killing, which ultimately leads to attrition of normal cells. Keeping this as the foundation of our study, we made an effort to compare the cytotoxicity(More)
Picrorhiza kurroa grown in the Northwestern Himalayan region is used in various herbal formulations but extensive harvesting of this plant has led it to near extinction. The active constituents responsible for the medicinal properties of P. kurroa have been identified as picroside-I and picroside-II which are present in a particular ratio (1:1.5) in herbal(More)
Kidney stone formation during hyperoxaluric condition is inherently dependent on the interaction between renal epithelial cells and calcium oxalate (CaOx) crystals. Although modern medicine has progressed in terms of removal of these stones, recurrence and persistent side effects restricts their use. Strategies involving plant based agents which could be(More)
BACKGROUND The increasing number of patients suffering from urolithiasis represents one of the major challenges which nephrologists face worldwide today. For enhancing therapeutic outcomes of this disease, the pathogenic basis for the formation of renal stones is the need of hour. Proteins are found as major component in human renal stone matrix and are(More)
