These novel N-substituted tetrahydropyrimidines based on phenylthiourea showed good inhibitory action against acetylcholinesterase (AChE), α-glycosidase, and human carbonic anhydrase (hCA) isoforms I and II. K i values of AChE enzyme were in the range of 0.48 to 7.46 nM. The hCA I and II were effectively inhibited by the compounds, with K i values in the range of 502.44 to 923.11 nM for hCA I and 400.32 to 801.57 nM for hCA II, respectively. The antioxidant activity of the novel N-substituted tetrahydropyrimidines based on phenylthiourea was investigated by using different in vitro antioxidant assays; including 1,1-diphenyl-2-picrylhydrazyl (DPPH·) radical scavenging, Cu 2+ and Fe 3+ reducing activities. © 2018 Wiley Periodicals, Inc.</dc:description><dc:publisher>John Wiley and Sons Inc.</dc:publisher><dc:date>2018</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/14355</dc:identifier><dc:identifier>https://doi.org/10.1002/jbt.22221</dc:identifier><dc:identifier>1095-6670</dc:identifier><dc:language>en</dc:language><dc:relation>Journal of Biochemical and Molecular Toxicology</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14355</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
