Database for vegetable phytochemicals and their mechanism of action.

ABSTRACT:

Unlabelled

In an endeavor to screen bioactive compounds present in vegetables with effective mechanism using in silico method lead us to develop a vegetable phytochemicals and their target database (VPTD). The VPTD is a unique bioinformatics resource that compiles information about phytochemicals from vegetables and their mechanism. VPTD contains 2496 phytochemicals from 27 vegetables, their 3D images and their 1337 possible biological mechanism. Each phytochemical contain records of seven data fields providing detailed information on name, source, amount present, structure and mechanistic information. This information has been manually extracted and manually verified from numerous sources, including other electronic databases, textbooks and scientific journals. VPTD is fully searchable and supports extensive text search. The main focus of the VPTD is on providing possible mechanism of phytochemicals, which will help in discovery of potential drugs from one of the common bioresource-vegetable. VPTD is freely available.

Availability

The database is available for free at http://www/vptd.in.

Project description:Background:Fumaria officinalis (F. officinalis, FO) has been used in many inflammatory and painful-ailments. The main aim of this work is to perform an in-depth bio-guided phytochemical investigation of F. officinalis by identifying its main-active ingredients. Optimizing pharmacokinetics via niosomal-preparation will also be done to enhance their in vivo antineuropathic and anti-inflammatory potentials, and to explore their possible-mechanism of actions. Methods:Bio-guided phytochemical-investigations including fractionation, isolation, chromatographic-standardization, and identification of the most active compound(s) were done. Optimized niosomal formulations of F. officinalis most active compound(s) were prepared and characterized. An in vivo biological-evaluation was done exploring acute, subchronic, and chronic alloxan-induced diabetes and diabetic-neuropathy, and carrageenan-induced acute inflammatory-pain and chronic-inflammatory edema. Results:In-vivo bio-guided fractionation and chromatographic phytochemical-analysis showed that the alkaloid-rich fraction (ARF) is the most-active fraction. ARF contained two major alkaloids; Stylopine 48.3%, and Sanguinarine 51.6%. In-vitro optimization, analytical, and in vivo biological-investigations showed that the optimized-niosome, Nio-2, was the most optimized niosomal formulation. Nio-2 had particle size 96.56?±?1.87 nm and worked by improving the pharmacokinetic-properties of ARF developing adequate entrapment-efficiency, rapid-degradation, and acceptable stability in simulated GI conditions. FO, ARF, and Nio 2 were the most potent antidiabetic and anti-inflammatory compounds. The reduction of the pro-inflammatory tumor necrosis factor-alpha (TNF-alpha) and Interleukin 6 (IL-6), and elevation the anti-inflammatory factor IL-10 levels and amelioration of the in vivo oxidative-stress might be the main-mechanism responsible for their antinociceptive and anti-inflammatory activities. Conclusions:Fumaria officinalis most-active fraction was identified as ARF. This study offers an efficient and novel practical oral formulation ameliorating various inflammatory conditions and diabetic complications especially neuropathic-pain.

Project description:Prunus cerasus (P. cerasus) is an alternative-medicine used traditionally for amelioration of chronic-ailments marked by elevation in oxidative-stress like neuropathy. The oxidative-stress control was reported to ameliorate the inflammatory-process. This study aimed to phytochemically-investigate P. cerasus most-active phytochemicals utilizing in-vivo biological models to explore their gastroprotective, anti-inflammatory, and antinociceptive potentials and their possible mechanisms of action. Sonication with EtAc was used to extract P. cerasus fruit (Scf), and seed (Scs). The phytochemical-investigation of Scf was performed by RP-HPLC, while that of Scs was explored utilizing GC-FID. A bio-guided-fraction and isolation method was done utilizing column-chromatography, and have shown that cyanidin-3-glucoside (Cy3G) was the most-active constituent in Scf, while linoleic-acid (LA) was the most-active constituent in Scs. Scf, Scs, Cy3G, and LA significantly (p ? 0.05) protected the gastric-mucosa against HCl/EtOH-induced gastric-lesions. Scs (200?mg/kg) has shown the most gastroprotective-potentials, and had comparable-results to ranitidine (50?mg/kg). Scf, Scs, Cy3G, and LA have shown significant anti-inflammatory and antinociceptive potentials against carrageenan induced-edema and nociceptive-pain, respectively, where Scs (200?mg/kg) has shown the most anti-inflammatory and antinociceptive potentials, and had comparable results to ibuprofen (100?mg/kg). Scf, Scs, Cy3G, and LA have counter-acted carrageenan-induced oxidative-stress markers, with increased serum-catalase and reduced-glutathione levels, and decreased lipid-peroxidation. Histopathological-studies demonstrated gastroprotective potentials, regeneration and improvement of the spleen-structural architecture when treated with highest doses of Scs and Scf. The reduction of the pro-inflammatory TNF-alpha and IL-6, and elevation the anti-inflammatory factor IL-10 levels, spleen regenerative-capacity and oxidative-stress amelioration might be the main-mechanism responsible for P. cerasus anti-inflammatory potentials. P. cerasus appears to aid in ameliorating the inflammatory process, and reducing pain-thresholds while preserving the stomach.
