Application

Application Comment Organism
additional information a potent inhibitor of phenylethanolamine N-methyltransferase, which exhibits a minimal affinity for the alpha-adrenoceptor, would be a useful pharmacological tool for clearly defining the connection between central epinephrine concentrations and blood pressure. Homo sapiens

additional information the series of 3-fluoromethyl-7-sulfonyl-1,2,3,4-tetrahydroisoquinolines is more lipophilic but less potent than the correspnding sulfonamides. The interaction of the human phenylethanolamnie N-methyltransferase main chain carbonyl oxygen of Asn39 with the sulfonamide -NH- is likely responsible for much of the enhanced inhibitory potency of the sulfonamides versus the sulfones.
