摘要

A series of cis-and trans-4-carboxy-3, 4, 5, 6-tetrahydropyrimidin-2 (lH)-ones possessing either a carboxy, hydroxymethyl, or mercaptomethyl substituent at C-6 were prepared and tested for their ability to inhibit mammalian dihydroorotase. Of these compounds, only the cis- 6-mercaptomethyl compound, cis-1, was found to be a potent competitive inhibitor of the enzyme (Ki= 140 nM at pH 7.4 and 8.5) when assayed in the direction of dihydro-L-orotate ...
