iap ( islet-activating protein , pertussis toxin ) is capable of uncoupling the receptor stimulation to activation of ni and/or n0 , thus resulting in the inhibition of negative inotropic and chronotropic responses to muscarinic receptor agonists , and to adenosine and its derivatives such as n6-phenylisopropyladenosine and n6-methyladenosine .
