  • Patent number: 6194437
    Abstract: The compounds of the instant invention are novel compounds of Formula I or a pharmaceutically acceptable salt thereof wherein Ar is phenyl or pyridyl unsubstituted or substituted. Ar1 can be independently selected from Ar and can also include pyridyl-N-oxide, indolyl, imidazole, and pyridyl; R3 can be independently selected from Ar or is hydrogen, hydroxy, NMe2, N-methyl-pyrrole, imidazole, tetrazole, thiazole (a), (b), (c), or (d), wherein Ar2 is phenyl or pyridyl. The instant compounds antagonize the bombesin receptors in mammals and are therefore effective in treating and/or preventing depression, psychoses, seasonal affective disorders, cancer, feeding disorders, gastrointestinal disorders, inflammatory bowel disease, sleep disorders, and memory impairment.

  • Patent number: 5726200
    Abstract: Novel pro-drugs to new and unnatural dipeptoids of .alpha.-substituted Trp-Phe derivatives useful as agents in the treatment of obesity, hypersecretion of gastric acid in the gut, gastrin-dependent tumors, or as antipsychotics are disclosed. Further, the dipeptoids are antianxiety agents and antiulcer agents. They are agents useful for preventing the response to the withdrawal from chronic treatment or with use of nicotine, diazepam, alcohol, cocaine, caffeine, or opioids. The pro-drugs are also useful in treating and/or preventing panic attacks. Also disclosed are pharmaceutical compositions and methods of treatment using the pro-drugs as well as processes for preparing them and novel intermediates useful in their preparation. An additional feature of the invention is the use of the subject pro-drug compounds in diagnostic compositions.
