      Drug Name Alfuzosin Riociguat
      Mechanism Antihypertensive agent
Alpha-1 adrenergic receptor  Antagonist
Hypotensive effects
Soluble guanylyl cyclase  Agonist
      Key Mechanism Factor 1
Factor Name Adrenergic receptor alpha-1 Structure Sequence
Protein Family G-protein coupled receptor 1 family
Protein Function
This alpha-adrenergic receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. Its effect is mediated by G(q) and G(11) proteins. Nuclear ADRA1A-ADRA1B heterooligomers regulate phenylephrine(PE)-stimulated ERK signaling in cardiac myocytes.
