For the synthesis of this class of compounds, glucose, galactose, arabinose, maltose, and lactose were used as aldehyde component in the reaction with barbituric acid and malononitrile to produce pyrano[2,3-d]pyrimidine derivatives. By use of 1,3-cyclohexanedione instead of barbituric acid, chromene derivatives incorporating carbohydrate moieties were obtained. Also, the four-component condensation reaction between d-glucosamine, aldehyde, malononitrile, and barbituric acid was efficiently provided polyhydroxy-substituted pyrido[2,3-d]pyrimidine derivatives. This new combinatorial approach gave a range of carbohydrate-derived heterocycles in good to excellent yields with high potential biological applications. The antioxidant activities were evaluated using 2,2\u2032-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) antioxidant measuring system, and the data were expressed as Trolox equivalent antioxidant capacity. All of these compounds display significant antioxidant activity. The maximum and minimum antioxidant activities were observed for 4j and 6b, respectively. Our results indicated encouraging perspectives for the improvement and usage of this type of synthetic compounds, indicating significant levels of antioxidant activity.<\/jats:p>","DOI":"10.1021\/acsomega.8b01124","type":"journal-article","created":{"date-parts":[[2018,8,31]],"date-time":"2018-08-31T13:54:42Z","timestamp":1535723682000},"page":"10341-10350","source":"Crossref","is-referenced-by-count":44,"title":["Synthesis and Antioxidant Activity\nEvaluation of Some Novel Aminocarbonitrile Derivatives Incorporating\nCarbohydrate Moieties"],"prefix":"10.1021","volume":"3","author":[{"given":"Soheila","family":"Khajeh Dangolani","sequence":"first","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0420-4409","authenticated-orcid":true,"given":"Farhad","family":"Panahi","sequence":"additional","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zohreh","family":"Tavaf","sequence":"additional","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryam","family":"Nourisefat","sequence":"additional","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reza","family":"Yousefi","sequence":"additional","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ali","family":"Khalafi-Nezhad","sequence":"additional","affiliation":[{"name":"Shiraz University , , ,","place":["Shiraz, Iran, 71454"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2018,8,31]]},"reference":[{"key":"2026090321074498700_cit1","doi-asserted-by":"publisher","first-page":"4267","DOI":"10.1021\/cr990374e","article-title":"Toward a carbohydrate-based chemistry: progress in the development\nof general-purpose chiral synthons from carbohydrates","volume":"100","author":"Hollingsworth","year":"2000","journal-title":"Chem.
