The previously disclosed spirohydantoin-based CGRP receptor antagonists were optimized for potency through modification of the benzimidazolone substituents. Compounds were identified which had minimal shift in the cAMP functional assay containing 50% human serum. Blockade of CGRP-mediated vasodilation was observed with these compounds in a rhesus pharmacodynamic assay and the in vivo potency correlated with the in vitro activity in the serum-shifted functional assay.
先前公开的基于螺环乙内酰脲的降钙素基因相关肽（CGRP）受体拮抗剂通过对苯并咪唑酮取代基进行修饰来优化其效力。鉴定出的化合物在含有50%人血清的cAMP功能测定中显示出最小的变化。在恒河猴药效学试验中观察到这些化合物对CGRP介导的血管舒张具有阻断作用，并且体内效力与血清转移功能测定中的体外活性相关。
