Input: Consider Input:  Following replicate control measurements , test ramps were repeated in the presence of sodium nitroprusside ( 1 microM ) and phentolamine ( 1 microM ) to eliminate potential smooth muscle and alpha 1 - adrenoceptor effects , respectively .

Output: alpha 1


Input: Consider Input:  These data suggest that reduction in PRA may have contributed to the hemodynamic effects of this peak III PDE inhibitor .

Output: peak III PDE


Input: Consider Input:  An in vitro Raf - 1 kinase assay , however , failed to detect LPS - induced Raf - 1 kinase activity in RAW 264 . 7 cells , suggesting that in RAW 264 . 7 cells , Raf - 1 kinase is not an activating component of the LPS signaling pathway regulating MAPK activity or sIL - 1Ra promoter activity .


Output: Raf - 1
