They represent a big group of structurally diverse compounds with intriguing physical, chemical and biological properties, which enabled them to be used in therapy, medicine in general, material science and industry. With the goal of broadening the set of potentially applicable hydantoin derivatives, we have synthesized a series of 2-thiohydantoins from vanillin and its derivatives, which themselves posses interesting biological properties. All compounds were fully characterized by NMR and IR spectroscopy. The compounds will be subjected to intensive biological screening to determine their biological properties and application opportunities.","PeriodicalId":20537,"journal":{"name":"Proceedings of The 23rd International Electronic Conference on Synthetic Organic Chemistry","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86435679","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}

On treatment with TFA, the oxazine closed form gets open in conjugation with the 1, 3, 3-Trimethylindoline species. This molecular change produces a bathochromic shift of 140nm directly from UV to Visible region in association with intense pink color. This molecule can be used as molecular ink to print a different colored decoration on paper. Upon addition with TEA, the colored open forms of the receptor revert to its original colorless form to rub the printed impression. Thus, the simple paper can be used for multiple times to achieve the write-read-erase strategy. This photoswitchable molecular motif can evolve many opportunities in the industry for printing purpose and huge paper consumption.","PeriodicalId":20537,"journal":{"name":"Proceedings of The 23rd International Electronic Conference on Synthetic Organic Chemistry","volume":"116 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87811412","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 catalytic efficiency of the SiO 2 /H 2 SO 4 was discussed through their utilization in the synthesis of biologically active substituted polycyclic quinoline derivatives ( 3 & 5 ) and the mechanism has been proposed. The SiO 2 /H 2 SO 4 was found as a effective catalyst for the Friedlӓnder reaction and gave considerable isolated yield of the targeted products under the mild reaction condition. The synthesized polycyclic quinolines ( 3 & 5 ) were characterized through diverse analytical techniques like FT-IR, NMR spectroscopy and single crystal X-ray diffraction studies.","PeriodicalId":20537,"journal":{"name":"Proceedings of The 23rd International Electronic Conference on Synthetic Organic Chemistry","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90772360","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}

Cancer is the uncontrolled proliferation of the body’s own cell. The cancer cells are dedifferentiated and lose their normal function. Cancer may be of two types metastatic and benign, out of which metastatic cancer is serious form. We are aware of the fact that the cancer cells differ from normal cells in many aspects. One such aspect is pH of cancer cells. The cancer cell has a pH lower than that of the normal cells of the body. In this research, we have prepared target-specific and pH-sensitive bioactive polymer using a combination of different natural polymer like polyvinyl alcohol, sodium alginate in a different ratio. Since, these polymers are pH sensitive, they will release the loaded drug only at the cancer site thus reducing the various side effects of the drug and drug toxicity.","PeriodicalId":20537,"journal":{"name":"Proceedings of The 23rd International Electronic Conference on Synthetic Organic Chemistry","volume":"54 3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89686654","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}

Molecular docking of the aurones was done successfully into the catalytic position of lipase (Pdb: 1LPB) using AutoDock Vina software 1.5.7.rc1. The results showed that 62 compounds interacted well with residues in the catalytic trial Ser152-Asp176-His263 and Phe77 of protein 1LPB. In particular, A32 was selected as the best binding compound (docking score: -10.6 kcal.mol-1) and suitable for oral drug following the 5-Lipinski rule. Combining the results of docking and molecular dynamics simulation of A32protein complex during 10 ns, this study performed that the A32 compound bound well and formed a stable complex with 1LPB protein. Therefore, the A32 compound was considered as the lead compound which could be synthesized and tested for pancreatic lipase inhibitor.","PeriodicalId":20537,"journal":{"name":"Proceedings of The 23rd International Electronic Conference on Synthetic Organic Chemistry","volume":"125 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82249696","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}
