substituent (R) attached at the N-6 position of 9. This study describes the syntheses and anti-HIV-1 testing of analogues with variations of the five-membered urea ring of the 4,5,6,7-tetrahydro-5-methylimidazo[4,5,1-jk] [1,4]benzodiazepin-2(1H)-one (TIBO) structures. Although many different rings were synthesized to replace the cyclicurea of TIBO, most were found to be inactive in inhibiting the replication

Substituted heteroaryl fused pyridine, pyrazine, and pyrimidine compounds that act as selective modulators of CRF 1 receptors are provided. These compounds are useful in the treatment of a number of CNS and periphereal disorders, particularly stress, anxiety, depression, cardiovascular disorders, and eating disorders. Methods of treatment of such disorders and well as packaged pharmaceutical compositions are also provided. Compounds of the invention are also useful as probes for the localization of CRF receptors and as standards in assays for CRF receptor binding. Methods of using the compounds in receptor localization studies are given.
