  Structure−Activity Relationships for Inhibition of Inosine Monophosphate Dehydrogenase by Nuclear Variants of Mycophenolic Acid

  摘要：

  Structure-activity relationships in the region of the phthalide ring of the inosine monophosphate dehydrogenase inhibitor mycophenolic acid have been explored. Replacement of the lactone ring with other cyclic moieties resulted in loss of potency, especially for larger groups. Replacement of the ring by acyclic substituents also indicated a strong sensitivity to steric bulk. A phenolic hydroxyl group, with an adjacent hydrogen bond acceptor, was found to be essential for high potency. The aromatic methyl group was essential for activity; the methoxyl group could be replaced by ethyl to give a compound with 2-4 times the potency of mycophenolic acid in vitro and in vivo.

• Synthesis of Tetra- and Pentasubstituted Benzenes from Dimedone and Derivatives

  DOI：10.1055/s-1992-26360

  日期：——

  Treatment of dimedone (5,5-dimethylcyclohexane-1,3-dione) and derivatives with one molar equivalent of sulfuric acid in trifluoroacetic anhydride leads, via sulfonation and a 1,2-methyl group migration, to a variety of dimethylresorcinol derivatives. The reaction has been performed on substrates bearing ester, alkoxy, halo and amino substituents to produce a variety of polysubstituted benzenes. Transient sulfonated intermediates were observed by NMR.
