Yet, the precise mechanism by which TTX blocks voltage-gated sodium (Na V) channels is not fully understood. Here molecular dynamics simulations are used to elucidate how TTX blocks mammalian voltage-gated sodium (Nav) channels and why it fails to be effective for the bacterial sodium channel, Na V Ab.1B) in TTX block of Na V channels [5] and [8] . Thus, the guanidine group of TTX may interact with the outer charged ring more intimately, rather than protruding into the filter. Here the inhibition of Na V Ab and Na V 1.4 by TTX is examined in atomic detail using molecular dynamics (MD) simulations.
Calcium channel blockers: Calcium channel blockers prevent calcium from penetrating muscle tissue in the heart and blood vessels. Since muscles need calcium to contract, calcium channel blockers cause blood vessels to relax and dilate, thereby lowering blood pressure. ARBs: These drugs prevent angiotensin from entering cells of the heart and blood vessels, dilating blood vessels and reducing the pressure the heart must work against. Direct-acting vasodilators: Unlike ACE inhibitors and ARBs, vasodilators directly relax the muscles in the walls of blood vessels.
