      Drug Name Nimodipine Pentoxifylline
      Mechanism 1 Antihypertensive agent
Calcium channel unspecific  Blocker 		Antihypertensive agent
      Key Mechanism Factor 1
Factor Name Voltage-dependent L-type calcium channel Structure Sequence
Protein Family Calcium channel beta subunit family
Protein Function
Regulatory subunit of L-type calcium channels (PubMed:1309651, PubMed:8107964, PubMed:15615847). Regulates the activity of L-type calcium channels that contain CACNA1A as pore-forming subunit (By similarity). Regulates the activity of L-type calcium channels that contain CACNA1C as pore-forming subunit and increases the presence of the channel complex at the cell membrane (PubMed:15615847). Required for functional expression L-type calcium channels that contain CACNA1D as pore-forming subunit (PubMed:1309651). Regulates the activity of L-type calcium channels that contain CACNA1B as pore-forming subunit (PubMed:8107964).
