It is caused by blood fluke, and the rate at which it causes death is alarming in some areas of America, Asia as well as in African countries. It is a neglected tropical disease (NTD) with grave impact on social and economic situation of countries with low sanitation awareness. Thus, the search for lasting solution to this menace, has drawn the attention of many global researchers using phytochemicals from Scilla natalensis via in silico approach. The studied compounds were optimized using Spartan 14. Docking study was executed via Pymol, Autodock tool, Auto dock vina and discovery studio. Compound 9 with –8.2 kcal mol–1 and –9.4 kcal mol–1 as binding affinity proved to possess highest ability to inhibit glutathione S-transferase and thioredoxin-glutathione reductase than other compounds. Also, ADMET properties for compound 9 and praziquantel were explored and reported. Our findings may open the door for the design of novel drug-like molecules with better efficiency.","PeriodicalId":35894,"journal":{"name":"Ecletica Quimica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76142218","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 contribution of the CIRC approach was measured by investigating whether the improvement in scientific literacy and regulated learning of the CIRC students are more significant than the improvement for students with the Direct Instructional Teaching Method (DITM) after experiencing two different teaching approaches. Two groups of students (experiment and comparison) from a public senior high school in East Java, Indonesia, were involved. The experimental group experienced the colligative properties of solution with the CIRC teaching approach, while the comparison group experienced the DITM one. We found that scientific literacy and self-regulated learning of students with CIRC are higher than students with DITM, implying the potency of this approach to be applied to other chemistry topics. This study indicates that CIRC could be used to improve students’ scientific literacy and self-regulated learning for other chemistry topics. The implication of this study for teaching colligative properties of solution is also discussed.","PeriodicalId":35894,"journal":{"name":"Ecletica Quimica","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78256093","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}

Firstly, the quinolinic acid was treated with acetic anhydride and acetic acid to form furo[3,4-b]pyridine-5,7-dione (1); the resulting compound was heated with urea to form 5H-pyrrolo[3,4-b]pyridine-5,7(6H)-dione (2). After that, it was treated with potassium hydroxide to give potassium 5,7-dioxo-5,7-dihydropyrrolo[3,4-b]pyridin-6-dione, which was directly and easily converted to 6-(2-([1,1'-biphenyl]-4-yl)-2-oxoethyl)-5H-pyrrolo[3,4-b]pyridine-5,7(6H)-dione (3) by the reaction with 1-([1,1'-biphenyl]-4-yl)-2-bromoethan-1-one. Finally, the resultant compound reacted with substituted aniline to give imines (4, 5). Secondly the quinolinic acid converted to 4-(5,7-dioxo-5,7-dihydro-6H-pyrrolo[3,4-b] pyridin-6-yl) benzenesulfonyl chloride according to our previous work, then treated with p-hydroxy acetophenone or p-hydroxy benzaldehyde to form 4-substituted bezyloxy 4-(5,7-dioxo-5,7-dihydro-6H-pyrrolo[3,4-b] pyridine-6-yl) benzenesulfonate (6, 7), which were finally treated with substituted aniline to form new substituted imines (8–12).","PeriodicalId":35894,"journal":{"name":"Ecletica Quimica","volume":"331 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75479227","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 obtained compounds were characterized by different physicochemical studies such as elemental analysis, atomic absorption, molar ratio analysis, electronic absorption (UV-Vis spectroscopy), magnetic properties, FTIR spectroscopy, 1H�NMR, 13C-NMR, conductance measurements and XRD. Antimicrobial and antioxidant activities were also calculated. The antibacterial activity was evaluated by the diffusion method against two Gram-positive and two Gram-negative bacteria, while antifungal activity was assessed against two fungal strains by using the agar method. The ligand with Schiff base and hydrazide groups and its complexes showed better biological activity. The results showed that the most metal complexes have much higher antibacterial and antifungal activity compared to the parent ligand. The antioxidant activity of 3.7453 mg of the ligand exhibited excellent activity as the activity of 1 mg of ascorbic acid which is used as a standard antioxidant.","PeriodicalId":35894,"journal":{"name":"Ecletica Quimica","volume":"93 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80216160","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}
