DESIGN AND MOLECULAR DOCKING OF SULFONAMIDE DERIVATIVES

Objective: Sulfonamides are a sulfa-related group of antibiotics, which are used to treat bacterial infections and some fungal infections. Some sulfonamides are also devoid of antibacterial activity, such as thiazide diuretics, etc. In this study, an effort was made to find out some novel and potent Sulfonamide derivatives as diuretic agents. Methods: Here, 30 three-dimensional sulphonamides are designed and docking simulation with PDB ID 1AZM which was downloaded from www. rcsb. org. All the molecules were also screened through a preliminary property filter (Molinspiration Property Calculator). Results: Among the 30 different molecules designed, 5 molecules were found to have a very good affinity towards the target protein. Conclusion: These molecular properties define if a molecule can be orally active in our body.

Chemical Composition, Diuretic, and Antityrosinase Activity of Traditionally Used Romanian Cerasorum stipites

Cherry stems (CS) represent a by-product intensively used in Eastern European countries as a traditional remedy for urinary tract disorders. Ethnopharmacological evidences sustain the use of CS as aqueous preparations (infusion and decoction), but few data were previously reported about phytochemical profile and pharmacological potential of CS hydroalcoholic extracts. In this regard, we aimed to evaluate the phenolic profile, in vitro antioxidant and tyrosinase inhibitory potential, and in vivo diuretic activity of 70% hydroethanolic cherry stems extract and cherry stems decoction (CSD). LC-DAD-ESI/MSn analysis revealed the presence of flavonoid-type compounds as main constituents for both preparations, especially flavanones (naringenin glycosides). Antioxidant activity evaluated through DPPH, ABTS, and FRAP methods was superior for cherry stems extract, probably due to the presence of phenolic-derived compounds in higher amounts than CSD. On the other hand, tyrosinase inhibitory potential and diuretic effect exerted by CSD were stronger, highlighting that other types of hydrophilic secondary metabolites are responsible for this bioactivity. Overall, our findings indicate that CS preparations could be used as promising mild diuretic agents and encourage further investigations regarding the correlation between their chemical composition and bioactive potential.

Diuretic Activity of Indian Medicinal Plant: A Review

Diuretics are commonly defined as drugs that increase the amount of urine produced by kidney. A precise definition is that diuretics are the agent which augment the renal excretion of sodium and either chloride or bicarbonate primarily, and water excretion secondarily. The term “saluretic” is sometime used to describe a drug that increase the renal excretion of sodium and chloride ion Diuretics are responsible for increase the rate of urine flow, sodium excretion and to maintain the volume and composition of body fluids in a various clinical Disorders. But drug-induced diuresis is very much beneficial in such type of life-threatening disorders like CHF, hypertension, renal failure, Liver cirrhosis and often pregnancy toxaemia.[1] Diuretics relieve pulmonary congestion and peripheral edema. This decreases cardiac workload, oxygen demand and plasma volume, thus decreasing blood pressure. Thus, diuretics play an important role in hypertensive patients.[2] Plant medicine is commonly used in the traditional treatment of some renal diseases, and many plants are reported to possess significant diuretic activity. The diuretic activity of a number of plants used in ethno medicine as diuretic agents has been confirmed in experimental animal. [3]The progress of a polyherbal formulation is a tough job because of the large number of different chemical compounds present in the different medicinal plants.

Acute and chronic toxicity studies on Polygonum glabrum in experimental animals

Polygonum glabrum is being used in traditional and folklore medicine to treat pneumonia and jaundice. Plant roots are used in ayurvedic preparations to treat fever and colic. The leaves are used as diuretic agents and process vermifuge action. Plant decoction is also used in the treatment of Rheumatism. Besides having many uses and folklore claims, herbal medicines are to be thoroughly investigated for their toxicity also. Therefore this work is being carried out to examine the toxicity of the drug and established dose is safe to use in the clinical stage. The current research studied the acute and chronic toxicity of Polygonum glabrum root extract in rats. It is proved that there was no change in any parameter tested both in acute and chronic toxicity, which means the extract is safe and non-toxic at the dose of 2g/kg also.

Comparison of pharmacological activity of hawthorn fruits preparations

Objectives - a comparative study of antidepressant activity and diuretic action of water and water-alcohol preparations of the fruits of Crataegus sanguinea Pall. and Crataegus submollis Sarg. Materials and methods. The study covers the water and alcohol-water extracts from the fruits of hawthorn blood-red (Crataegus sanguinea Pall.) and Quebec hawthorn (Crataegus submollis Sarg.). The comparative study of the antidepressant activity and the diuretic action of the preparations was carried out on white mongrel rats of both sexes. Results. The liquid extracts of fruits Crataegus sanguinea Pall. and Crataegus submollis Sarg. at a dose of 100 μl/kg revealed an antidepressant activity. Decoctions of Crataegus sanguinea Pall. and Crataegus submollis Sarg. at a dose of 100 μl/kg had a pronounced diuretic and saluretic activity. Pharmacotherapeutic effects of the studied preparations can be explained by the presence of flavonoids in them. Conclusion. The preparations of the fruits of Crataegus sanguinea Pall. and Crataegus submollis Sarg. can be recommended as antidepressant and diuretic agents. The fruits of Crataegus submollis Sarg. are the promising medicinal plant raw materials.

PENETAPAN KADAR FENOLIK TOTAL EKSTRAK ETANOL DAUN SERUNAI (Chromolaena odorata L.) DENGAN METODE SPEKTROFOTOMETRI UV-Vis

Serunai (Chromolaena odorata L.) is a medicinal plant, including the Asteraceae family. Serunai is used to treat wounds, mouthwash to treat sore throats, coughs, malaria drugs, headache medications, antidiarrheals, antimicrobials, antispasmodics, antihypertensive, anti-inflammatory and diuretic agents. Serunai plants contain chemical compounds tannins, phenols, flavonoids, saponins and steroids. The purpose of this study was to determine the total phenolic content of the leaves of serunai using the UV-Vis spectrophotometric method. The stages of the research include plant determination, sampling, making of simplicia leaf of serunai, making extract by maceration method, phenolic compound test, determination of total phenolic levels by UV-Vis spectrophotometry with Folin-Ciocalteu reagent, comparing gallic acid. The results obtained by an average of total phenolic levels of ethanol extract of serunai is 171.30368 ± 1.9694 mg GAE / g means that in every gram of ethanol extract of flattened leaves is equivalent to 171,30368 mg gallic acid.
