- The discovery of 1,2,3,9b-tetrahydro-5H-imidazo[2,1-a]isoindol-5-ones as a new class of respiratory syncytial virus (RSV) fusion inhibitors. Part 1
-
Respiratory syncytial virus (RSV) is a major cause of respiratory tract infections in infants, young children and adults. Compound 1a (9b-(4-chlorophenyl)-1-(4-fluorobenzoyl)-1,2,3,9b-tetrahydro-5H-imidazo[2,1-a]isoindol-5-one) was identified as an inhibitor of A and B strains of RSV targeting the fusion glycoprotein. SAR was developed by systematic exploration of the phenyl (R1) and benzoyl (R2) groups. Furthermore, introduction of a nitrogen at the 8-position of the tricyclic core resulted in active analogues with improved properties (aqueous solubility, protein binding and log D) and excellent rat pharmacokinetics (e.g., rat oral bioavailability of 89% for compound 17).

- 5H-imidazo[2,1-a]isoindol-5-one compounds
-
A new class of chemical compounds whose members exert an appetite suppressant and mood elevating effect in man has been invented. This class is defined as being composed of those compounds having the 1-substituted-2,5-benzodiazocine structure, fully saturated in the nonbenzenoid portion, and whose nitrogens are tervalent. Members of this class are prepared by condensing an orthobenzoylbenzoic acid or ester thereof with an ethylenediamine and reducing with a metallic alkaline hydride the product thus obtained.
