Functionally Biased Agonists. Conversely, a compound presenting as an agonist in 5-HT2B functional assays does not necessarily pose a risk for valvulopathy. In 5-HT2B calcium flux assays, certain known VHD-associated compounds displayed an agonist profile comparable to that of ropinirole, an approved treatment for Parkinson's disease (PD) and restless leg syndrome.122 Because ropinirole is not known to be associated with VHD or similar cardiopathies, it is thought that calcium flux may not be the optimal assay for screening 5-HT2B agonists for potential VHD-related risks. In additional readouts of 5-HT2B receptor activation (calcium-sensitive NFAT-mediated transcription of a β-lactamase reporter gene, accumulation of InsPs in LiCl-treated cells, recruitment of β-arrestin to agonist-occupied receptors, and phosphorylation of the extracellular signal-regulated kinase ERK2), ropinirole was found to be "distinct from the seven known valvulopathic 5- HT2B receptor agonists [studied] in that it is much less potent, albeit not less efficacious, than the VHD-associated drugs in all but one of the 5-HT2B receptor functional assays employed." 66
