smaller objects, such as a potassium ion attempting to fit into a sodium channel. Conversely, some objects are too small to be properly stabilized by certain channel pores, such as a sodium ion attempting to pass through a potassium channel. In both cases, channel flux is not permitted. However, as long as a particular compound possesses adequate chemical affinity to a channel, that compound may be able to bind and block the channel pore. For example, TTX can bind and inactivate voltage-gated sodium channels, despite the fact that TTX is much larger and chemically different than sodium ions. Given the disparities in size and chemical properties between TTX and a sodium ion, this is an example of structure being used to block usually specific channels.
81: 253:. Local anesthetics work by inducing a phasic block state in the targeted neurons. Initially, open channel blockers do not effectively prevent action potentials, as few channels are blocked and the blocker itself can be released from the channel either quickly or slowly depending on its characteristics. However, phasic blocks occur as repeated depolarization increases blockers’ affinity for channels in the neuron. The combination of an increase in available channels and the change in channel conformation to increase blocker binding affinity are responsible for this action. 342:, as they can inhibit the hyper-excitable tissues in a patient. Introducing specific sodium channel blockers into a tissue allows for the preferential binding of the blocker to sodium channels, which results in an ultimate inhibition of the flow of sodium into the tissue. Over time, this mechanism leads to an overall decrease in tissue excitation. Prolonged hyperpolarization interrupts normal channel recovery and allows for constant inhibition, providing dynamic control of the anesthetics in a given setting. 86: 85: 82: 87: 204: 84: 306:
treatment, memantine has been shown to allow excitatory post-synaptic currents to remain unaffected while decreasing the incidence and amplitude of inhibitory post-synaptic currents. Evidence supports the hypothesis that both the strong voltage dependency and fast kinetics of memantine may be responsible for the decreased side effects and cognitive progress.
282:, as a treatment option for neurotoxicity. They have hypothesized that the faster blocking and unblocking rates, and overall kinetics, of memantine could be the underlying reason for the clinical tolerance. As an uncompetitive antagonist, memantine should bring NMDA levels close to normal despite high 60:
Molecules that act as channel blockers are important in the field of pharmacology, as a large portion of drug design is the use of ion channel antagonists in regulating physiological response. The specificity of channel block molecules on certain channels makes it a valuable tool in the treatment of

These ion channels are most often gated, meaning they require a specific stimulus to cause the channel to open and close.

Various types of substances have been known to block CFTR chloride ion channels. Some of the best-known and studied substances include sulfonylureas, arylaminobenzenoates, and disulfonic stilbenes. These blockers are side-dependent as they enter the pore exclusively from the cytoplasmic side,

Blockage of this channel by certain cytoplasmic, negatively-charged substances results in reduced chloride ion and bicarbonate anion transport, as well as reduced fluid and salt secretion. This results in a buildup of thick mucus, which is characteristic of cystic fibrosis. 31: 182:
also provides clues to the chemical makeup of the molecule and why it binds to a certain region. For example, if a protein binds to a hydrophobic region of the channel (and therefore, has a transmembrane region), the molecule in question might be composed of the amino acids

Electrophysiology is also an important tool in identifying channel structure, as analyzing the ionic factors that lead to channel activation can be critical to understanding the inhibiting actions of open channel block molecules. 161:(TTX), a toxin found in pufferfish, completely blocks sodium ion transportation by blocking the selectivity filter region of the channel. Much of the structure of the pores of ion channels has been elucidated from studies that used toxins to inhibit channel function. 107:

CFTR channels mediate bicarbonate anion entry which is essential for sperm 278:. Researchers have examined many different NMDA antagonists and their therapeutic efficacy, none of which have concluded to be both safe and effective. For years, researchers have been investigating the effects of an open channel block, 248:
