[PAR] [TLE] Bentley compounds [SEP] The Bentley compounds are a class of semi-synthetic opioids that were first synthesized by K. W. Bentley by Diels-Alder reaction of thebaine with various dienophiles.  The compounds are also known as thevinols, orvinols, or bridged oripavine derivatives, due to the characteristic 6,14-"endo"-etheno- bridge and substitution at the 7α position.  Buprenorphine and etorphine are perhaps the best known of the family, which was the first series of extremely potent μ-opioid agonists, with some compounds in the series having over many thousands of times the analgesic potency of morphine. [PAR] [TLE] Buprenorphine [SEP] Buprenorphine, sold under the brand name Subutex, among others, is an opioid used to treat opioid addiction, moderate acute pain and moderate chronic pain.  The combination buprenorphine/naloxone is also used for opioid addiction.
