Pomegranate extracts (PGEs) exhibit antioxidative, antiproliferative, and antineoplastic activities. 2-Methoxyestradiol (2-ME), the end metabolite of 17β estradiol (E2), an antiangiogenic agent, inhibits tumor growth. Our earlier investigations demonstrated that aqueous PG extract (PGE) in combination with 2-ME showed antineoplastic effect on Sarcoma-180 tumor cells. The present paper has been oriented to evaluate the antimutagenic or anticlastogenic effect of PGE in combination with 2-ME on normal Swiss albino mice. A comparative evaluation of the antioxidant potential and free radical scavenging activity of ethanolic and aqueous extracts of PG was evaluated by total phenol, flavonoidand Ferric reducing antioxidant power assay (FRAP) content as well as 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity. Ethanolic extract showed more amounts of phenolic compounds, which is a good sign of high antioxidative potentiality. The aqueous extract has high flavonoid content, which dominates the phenolic activity of the ethanolic extract. The aqueous extract has high Ferric reducing power with more scavenging activity in DPPH assay, which promotes the extract to give a protective property. Present results demonstrated that combination...

Present study was aimed to search bioactive functional groups and compounds in the whole animal extract of a marine cnidarians Zoanthus sansibaricus by FT-IR and GC-MS. The methanol extract was used to detect bioactive functional groups and compounds. GC-MS of the animal extract was done, and FTIR analysis was thereafter used to identify the functional groups. The bioactive components were identified based on peak values in the region of infrared radiation. Results of GC-MS revealed eight major compounds like Undecane (13.16%), 2,6-Diisopropylnaphthalene (3.47%), Cyclohexasiloxane, dodecamethyl (6.33%), 6, 11-Undecadiene, 1-acetoxy-3, 7-dimethyl (2.84%), n-Hexadecanoic acid (19.91%), Triphenylphosphine oxide (4.34%), beta. -Sitosterol acetate (43.32%) and Dihydroartemisinin,6-deshydro-5-deshydroxin (6.64%). These are bioactive compounds may act as antimicrobial, antiviral, anti-inflammatory, and antioxidant agents. FT-IR analysis results also indicated the presence of functional groups like N-H (amide group), O-H (carboxylic acid and alcohol), C-H (carboxylic acid and alkanes), and C-F (alkyl halide group) in the...

The novel human coronavirus which has been designated as SARS-CoV2 initially appeared in December 2019 in Wuhan, China causing a respiratory illness called COVID-19. The SARS-CoV2 is a β coronavirus belonging to the family Coronaviridae is a global public health emergency infecting many people all around the world, especially in India with more than 10.8 million cases. Henceforth there is an urgent requirement for a novel drug that counters SARS-CoV2. The present study was intended to evaluate the therapeutic potential of natural products in plants as a potential inhibitor of SARS-CoV2 Mpro (6Y2F, 6Y2G, 6YB7). Molecular docking was performed by Autodock version 4.2, by means of the Lamarckian Genetic Algorithm, to evaluate the possibility of docking. SARS-CoV2 Mpro was docked with twenty-two compounds namely Apigenin, Coriandrin, Curcumin, Catechin, Quercetin, Oleanolic acid, Rosmarinic acid, Ursolic acid, Glucobrassicin, Kaempferol, Gingerol, Naringenin, Carvacrol, Limonene, Eucalyptol, Berberine, Luteolin, Gallic acid, Gedunin, and Nimocinol, and docking was analyzed by Autodock 4.2 and Pymol. HIV drugs, Nelfinavir and Saquinavir, were used as standards for comparison....

Deracoxib is a coxib class of Non Steroidal Anti-Inflammatory Drug (NSAID). Like other NSAIDs, its effects are caused by inhibition of Cyclooxygenase (COX) enzymes. Deracoxib causes greater inhibition of COX-2 than of COX-1. The aim of this proposed method was to develop and validate the UV spectrophotometric method for the routine quality control check of API containing 25 mg Deracoxib intablets dosage form. To investigate the most preferable dissolution method includes dissolution media as pH 6.8 sodium phosphate buffer + 1 % Sodium Lauryl Sulphate, 900ml, temperature as 37±0.5°C, RPM as 75, time 45 min. The absorbance maximum of Deracoxib was found to be 255nm. The concentration range of the proposed method was 5-15µg/ml and linearity as r2 = 0.9959.The result of intraday &interday precision was 0.1458% and 0.1214% RSD respectively. The results of the percentage recoveries were 99.2%, 99.3%, and 99.1%. The effective dissolution method was developed and validated by UV spectrophotometer which used to be more applicable in various pharmaceutical...

The present study was aimed to formulate and evaluate floating microspheres of Baclofen. The research work’s objective was to retain Baclofen in the stomach for a prolonged period of time, which has absorption window in the upper gastrointestinal tract. The microspheres were prepared by solvent evaporation technique. A 32 full factorial was applied to investigate the combined effect of the two independent variables, i.e., the concentration of Eudragit RL100 (X1) and concentration of Eudragit RS 100 (X2) on the dependent variables particle size (Y1), percentage drug entrapment efficiency (Y2), percentage buoyancy (Y3), in-vitro drug release at 1 h (Y4), in-vitro drug release at 6 h (Y5). Results of the multiple regression analysis revealed that in-vitro drug release decreased and particle size, percentage drug entrapment efficiency, percentage buoyancy was increased with increasing the concentration of Eudragit RL100 and Eudragit RS100. The optimized formulation has a particle size of 115.96 µm, percentage drug entrapment of 90.06%, and buoyancy of 90.76%. In-vitro drug release of Baclofen floating microspheres showed a sustained release...
