Resumo(s)
The encapsulation of odorants by the synthetic receptor
cucurbit[7]uril (CB[7]) reduces the response of olfactory receptors in
Mozambique tilapia (Oreochromis mossambicus) in vivo. For example, the
olfactory receptor response to the odorant adamantan-1-amine, as
measured by electro-olfactography, was suppressed by 92% in the
presence of CB[7]. A reduction in olfactory response of 88% was
observed for pentane-1,5-diamine (cadaverine), an odorant associated with
carrion avoidance in some fish. The results reveal how the association
constants and the concentrations of natural and synthetic receptors play a
determinant role and show that synthetic receptors can be used to remove
bioactive molecules from fish olfaction.
