Pyrazoline, among the various 5-membered heterocyclic compound derivatives has drawn attention towards it because of its various pharmacologically activities associated with it. Pyrazolines are a five membered heterocyclic having two adjacent nitrogen atoms within the ring with only one endocyclic double bond and is basic in nature. A lot of research work has been done on synthesis and biological activities of various pyrazoline derivatives over the years. Pyrazolines derivatives display tremendous biological activities such as antimicrobial, anti-inflammatory, analgesic, antipyretic, antidepressant, antitubercular, antiamoebic, anthelmintic, anticonvulsant, antihypertensive, antidiabetic, antitumor, anti-HIV, local anaesthetic, antioxidant, insecticidal, tranquilizing and receptor selective biological activity. The history of pyrazoline shows that it attracted many chemists to explore pyrazoline as a biologically active molecule. The study of biological evaluation of pyrazoline derivatives has been an interesting field of pharmaceutical chemistry. This review article focuses on the pharmacological profile of pyrazoline with various activities and examples in form of...

Solubility is considered as the important parameters to achieve desired concentration of drug in systemic circulation for achieving required pharmacological response. Olmesartan medoxomil (OLM) is poorly soluble belongs to BCS class II. The drug is rapidly absorbed following oral administration, with a bioavailability approximately 26%. Liquisolid technique was used to enhance the aqueous solubility and dissolution rate to obtain faster on set of action, minimize the variability in absorption, and improve its oral bioavailability. The aim of the present study was to develop Olmesartan medoxomil liquisolid tablets using Quality by Design (QbD) approach to screen the effect of four formulation and process factors on the formulation. OLM liquisolid tablets were prepared by Liquisolid technique. Plackett-Burman (PB) design was used to screen the effect of four formulation and process factors to improve solubility and bioavailability. The liquisolid formulation were characterized by pre and post compression parameters, DSC, XRD, SEM, and in-vitro drug release. Excipients like Neusilin US2, Aerosil 200, PEG 400 and Primojel showed an influential effect on the selected...

Aim of the present study was a comparative evaluation of antianxiety activity of three traditionally used medicinal plants — Argyreia speciosa (Roots), Caesalpinia digyna (Roots) and Sphaeranthus indicus (Flowers). The activity of various extracts (petroleum ether, chloroform, ethanol and water) of all the three plants was evaluated using elevated plus-maze model. The studies were conducted on lacca mice, and the test materials were administered per oral route. Results indicate that the ethanol extract of C. digyna roots exhibited maximum and significant dose dependent effect at 200 and 400 mg/kg on elevated plus-maze, the results were comparable to the standard antianxiety drug diazepam (2...

The pharmacological activity of Withenia somnifera commonly called Ashwagandha, a herb having multi-medicinal properties, was investigated against carbofuran exposed hepatic anomalies in the air breathing fish Clarias batrachus. Fishes were exposed to 1 mg/L carbofuran for three weeks to induce the toxic effects. These fishes were then fed with Withenia somnifera root extract mixed pelleted feed @ 10% of the total feed ingredients for the next 6th and 8th week respectively. The histopathological examination of hepatic tissues was done on light microscopy and transmission electron microscopy. Major changes attributed to the hepatic cells after carbofuran treatment showed irregular shape of hepatic cells, increased sinusoidal spaces, rough endoplasmic reticulum, secretary granules, dilated mitochondrial cristae and presence of kupffer cells. Amoeboid nucleus with increased heterochromatin material, granular nucleoplasm and enlargement of nucleolus, were some of the prominent histopathological alteration in the liver tissue after carbofuran toxicity at transmission electron microscope (TEM) level. The histopathological examination of liver cell of carbofuran exposed fish followed by administration of W.somnifera root extract mixed pelleted...

Objective: To evaluate hypoglycemic responses of Kasni (Cichorium intybus) seed preparations in combination with oral hypoglycemic agent in treatment of patients of newly diagnosed type2DM. Methods: Newly diagnosed 90 patients of type2DM, age 35-65years, of either sex were divided into 3 groups. Each group had 30 patients (19 male and 11 females) matched with each other in terms of age and sex. In group A, only Glycomet SR once a day and in group B/C 6 grams crude seed powder or 50 ml decoction of crude seed powder twice a day in combination with Glycomet SR once in a day, was given for 90 days. FBG and PPBG were measured across 7 time periods and HbA1c levels were measured at zero and 90th day. Results: All the three groups shown a significant reduction in FBG and PPBG across the seven time periods. Post hoc TukeyHSD test shown that there was a significant difference between group A&B (p=0.027) and group A&C (p=0.000) for FBG and group A&B (p=0.019) and group...
