The rate of transfer between the central compartment ( i . e . , blood ) and the peripheral compartment ( e . g . , tissue ) for each brevetoxin differed substantially , with dihydro - BTX - B exchanging rapidly with the peripheral compartment , and S - desoxy - BTX - B2 eliminating rapidly from the central compartment and N - palmitoyl - S - desoxy - BTX - B2 eliminating slowly from the central compartment .
 Chemical: brevetoxin; Chemical: dihydro - BTX - B; Chemical: S - desoxy - BTX - B2; Chemical: N - palmitoyl - S - desoxy - BTX - B2
