Dear Stephan and Joshoua.
I think that if you look in the RBI catalog, you will notice that selective
5-HT1B agonists or antagonist are NOT comercially available.
There are some agents that might be used:
- TFMPP is not selective for 1B but has a slightly higher
preference for this recepor than others
- RU 24969 similar
-CGS 12066 has reasonable selectivity for 1B
-The newly introduced agonist from Pfizer CP 93129
has reportedly good selectivety and potency at 1B receptors.
This is NOT comercially available.
-No selcetive antagonists available to date,
use cyanopindolol for example, although this is also equipotent at 1A
in addition to being a beta-adrenergic receptor antagonist.
