COMPOUNDS AND COMPOSITIONS AS INHIBITORS OF CANNABINOID RECEPTOR 1 ACTIVITY

The invention provides compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with the activity of Cannabinoid Receptor 1 (CB1).

Facile synthesis of 1-substituted 4,5-diaminopyrazoles and its application toward the synthesis of pyrazolo[3,4-b]pyrazines

1-Substituted 5-aminopyrazole-4-carbonylazides were prepared from the appropriate 5-aminopyrazole-4-carboxylates. The acyl azides undergo a Curtius rearrangement followed by quenching with alcohols to form the corresponding carbamates. The 1-substituted 5

A new efficient route to imidazo[4,5-c]pyrazol-5-ones

The synthesis of imidazo[4,5-c]pyrazol-5-ones (6) is reported. 5-Amino-4-ethoxycarbonylaminopyrazoles 3a-g when heated at 200°for 2 hours afford 6a-g. In a similar manner imidazo[4,5-c]pyrazol-5-one (6a) is readily obtained from 4-amino-5-ethoxycarbonylaminopyrazole (5a).
