Thirty-three pyridazine-based compounds (compounds 1 to 33) were designed. The in silico studies were conducted to predict their toxicity, docking scores (DS), pharmacokinetic parameters, and drug-likeliness properties compared to celecoxib. Based on the safety and efficacy data obtained by in silico studies, four compounds (7, 12, 16, and 24) were synthesized, and the spectral analysis confirmed their chemical structures. Additionally, the in vitro COX-2 inhibitory activity of these four compounds was evaluated. Eleven compounds were predicted as non-toxic compounds. The DS of four compounds, 7 (DS = -9.72 kcal/mol), 12 (DS = -10.48 kcal/mol), 16 (DS = -9.71 kcal/mol), and 24 (DS = -9.46 kcal/mol), was better than celecoxib (DS = -9.15). These compounds (7, 12, 16, and 24) also demonstrated better oral absorption (83.53% each) than celecoxib (79.20%) in addition to their promising drug-likeliness properties. The compounds 7 (101.23%; p < 0.05), 12 (109.56%; p < 0.05), 16 (108.25%; p < 0.05), and 24 (103.90%; p < 0.05) also exhibited superior COX-2 inhibition to celecoxib (100%; p < 0.05). Compounds 7, 12, 16, and 24 are useful lead compounds in developing drugs for various diseases in which high levels of COX-2 are implicated.","PeriodicalId":19599,"journal":{"name":"Oriental Journal Of Chemistry","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136069186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The linear regression coefficients (R-square) of the methods range from 0.998 to 0.999, and the Limit of Detection (LOD) and Limit of Quantification (LOQ) are 1.56 to 25.23 ng/mL and 4.72 to 76.47 ng/mL, respectively. Recoveries of all spiked pesticides range from 82.6 to 117.6%, with a RSD (Relative Standard Deviation) less than 11.2%. The results show that 42 out of 45 pesticides were detected in whole citrus fruit pulp (with peel) samples. Fenthion, bifenthrin, and fenvalerate were not detected. In the collected citrus samples, phorate (21.71 µg/kg), and ethion (51.47 µg/kg) insecticides are present above the Maximum Residue Level (MRL), but cypermethrin (25.89 µg/kg) was detected below the MRL. 13 out of 45 pesticides were detected in edible parts of citrus fruit (without peel) samples, with ethion having the highest residue. All pesticides were within the MRL limits prescribed by the European Union (EU) and Codex regulations for MRL in citrus fruits, and peeling was found to be one of the best ways to get rid of pesticide residues.","PeriodicalId":19599,"journal":{"name":"Oriental Journal Of Chemistry","volume":"58 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136069783","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Kanakasava, Kanakasava distillate and Kanakasava nebulizer solution were prepared accordingly and standard GC-MS analysis was performed on the samples. Results: The GC-MS analysis indicated the presence of 6, 13 and 10 important phytochemicals in Kanakasava, Kanakasava distillate and Kanakasava nebulizer solution respectively. Many chemicals acting on the respiratory system were found in all three forms of Kanakasava and some of the chemicals were having similar actions.

Here a hydrophobic associated polymer (HPA) by introducing a nonionic hydrophobic monomer (AO) was designed as the acid thickener. The experimental results demonstrated that HPA suggests excellent acid resistance, shear resistance, and thermal stability attributing to the gradual exposure of hydrophobic chain to H2O circumstances that enhances the strength of hydrophobic association. The square radius of gyration of HPA raises with the introduction of AO confirming the unfold of HPA by intermolecular hydrophobic association, which strengthens the network structure. The decrease of mean square displacement and diffusion coefficient of H2O and H3O+ molecules suggest the enhancement for network structure by hydrophobic chain owing to HPA hindered the diffusion of H2O and H3O+ molecules.
