Objective: This dissertation work aimed to prepare Levocetirizine HCL (LCH) nasal in-situ gel, a second-generation antihistamine, to improve its retention time, sustain release, enhance the bioavailability, and avoid first-pass metabolism. Process: The in-situ nasal gel was prepared to consume Carbopol as a gelling agent, Hypromellose (HPMC) as a thickening or thickness-imparting agent, and buffering agents to maintain pH. An assessment was conducted to determine the solubility, pH, rheological characteristics, consistency of content, adhesive properties to mucous membranes, gel strength, in-vitro release characteristics, the kinetics of release date, isotonicity, and sterility of the sample. Results: All formulations had a clear appearance with good gelling capacity, and drug content was found to be >87%. The pH values of the formulations were found to be acceptable, ranging from 6.2 ± 0.10 to 6.4 ± 0.44, and no irritation of the mucosal membranes was observed. The shearing character was found between 200-1400 at pH 6.4 and 2000-5500 cps at pH 7.4 when measured at 20 rpm. They also showed adequate gel strength of...

Optimizing the cultural conditions to enhance bioactive metabolite production by Streptomyces rubrus VLK-24 isolated from mangrove sediments as well as characterizing these compounds, has been taken up in this study. The culture broth inoculated in Yeast extract, Malt extract, and Dextrose broth and extracted with ethyl acetate exhibited high antimicrobial activity against test microorganisms, including Gram-negative and Gram-positive bacteria as well as fungi. The crude ethyl acetate extract exhibiting high antimicrobial activity was analyzed by Gas Chromatography-Mass Spectroscopy, which evidenced the presence of 39 compounds according to the available library data, NIST MS Search (ver. 2.0). The results of the study revealed the production of diversified metabolites by the strain; hence it could be a possible source for novel antimicrobial...

For the present study, 10 bacterial strains were isolated from agriculture field soils collected from Guntur, Andhra Pradesh, India, and thereafter screened for amylase activity. Among them, the strain DS5 showed a maximum zone of clearance on the starch hydrolysis test was selected for this study. Identification of bacterial strain DS5 was confirmed by 16S rRNA sequencing analysis. The phylogenetic tree constructed on the basis of 16S rRNA sequences revealed that it clustered with the closest members of Bacillus pumilus DS5 and the sequences were deposited in NCBI Gen bank along with accession number MK430437. Further the effect of incubation period, temperature, pH, carbon and nitrogen sources was optimized. Highest amylase production was found after 48 h of incubation at pH 7.0 and 40 ⁰C temperature. Starch proved to be the best carbon source and peptone as nitrogen source for the highest production of amylase by Bacillus pumilus DS5. Supplementation with different nitrogen and carbon source favoured the increased enzyme yield by submerged...

Diabetes mellitus is a complex disorder where oxidative stress plays a crucial role in the development and progression of the disease. In the present work, the rat model evaluated pancreas and liver tissue damage caused by a high-fat diet and diabetic complications. Male Wistar rats were administered with HFD- corn oil orally for 28 days followed by streptozotocin (STZ) injection to induce diabetes on 29th day. The drug treatment groups were given low dose (250mg/kg) and high dose (500mg/kg) of hydroalcoholic extract of Achyranthes aspera (HEAA), and its therapeutic efficacy in HFD + diabetes model was compared with the standard drug metformin. Various antioxidant parameters were measured, including MDA, protein, GSH levels, SOD, and CAT activities. The histology of pancreas tissues was also analyzed using Haematoxylin, Eosin, and Masson-trichrome staining. The expression of insulin protein in the pancreas was studied by immunohistochemical technique. The effect of drugs on GLUT-2 and PPAR-α gene expression showed considerable improvement in the liver tissues of different groups. From the results, it can be...

Background: Our study aims to document the use of ethnomedicinal plants reported by herbalists in treating ailments that are becoming more prevalent. Using an ethnobotanical approach and in-silico studies, will advise further prevalence and give precedence to future pharmacological studies. Methods: The application of the plants was reported by 75 informants. From the 51 reported plants, 20 plants were frequently cited as having high potential anti viral and anti-inflammatory activity and were validated in in-silico approach. PASS was used for compound prediction, and AMT was calculated with the help of ADMET lab 2.0. Results: Out of the 20 plants validated in in-silico, the results of reported compounds revealed that Aeginetia indica could best act as an antiviral agent with Pa (0.939) and Pi (0.003), followed by Bacopa monnieri with Pa (0.880) and Pi (0.002) and Blumea balsamifera with Pa (0.743) and Pi (0.004). Subsequently, the plant which can act as the best anti-inflammatory ailment is Andrographis paniculata with Pa (0.845) and Pi (0.005), followed by Pisum sativum with Pa...
