Dofetilide (UK 68789) is a sulfonamide class III antiarrhythmic agent and potassium channel blocker. Dofetilide selectively blocks cardiac ion channels of the rapid component of the delayed rectifier potassium current Ikr. This antiarrhythmic agent prolongs cardiac action potential duration and effective refractory period due to delayed repolarization without affecting conduction velocity. This results in a normal sinus rhythm. Dofetilide is used in the treatment of atrial fibrillation and flutter.

Nadolol is a non-selective beta-adrenergic antagonist with antihypertensive and antiarrhythmic activities. Nadolol competitively blocks beta-1 adrenergic receptors located in the heart and vascular smooth muscle, inhibiting the activities of the catechola

Etripamil (MSP-2017) hydrochloride is a fast-acting L-type calcium channel blocker used in the study of paroxysmal supraventricular tachycardia (PSVT). By inhibiting calcium ion influx through slow calcium channels, etripamil hydrochloride slows atrioventricular nodal conduction and extends the atrioventricular nodal refractory period.

Dimephosphon is an anti-inflammatory agent exhibiting both antihistamine and antiserotonin activities. It aids in maintaining spinal cord conduction function and reduces the excitability of motor neurons around lesion areas. Additionally, Dimephosphon directly stimulates lymph vessel movement, enhancing lymph circulation. This compound is useful for studying inflammatory edema, acute spinal cord injuries, and lymphatic circulation disorders.

NGI-189 is a selective OST-A inhibitor. Its main mechanism is to inhibit the activity of the STT3A catalytic subunit in the OST complex, thereby reducing the N-glycosylation level of target glycoproteins. It effectively blocks the conduction of oncogenic and bypass signaling pathways, significantly downregulates the phosphorylation levels of EGFR, AKT, p70S6K and S6RP proteins, and induces cell cycle arrest and apoptosis. In non-small cell lung cancer (NSCLC) xenograft models, NGI-189 significantly inhibits tumor growth and induces tumor regression, making it a potential tool molecule for mechanism and efficacy research of EGFR-mutant non-small cell lung cancer.

Spinetoram J belongs to the macrolide class of insecticides. Spinetoram J acts on nicotinic acetylcholine receptors (nAChR) and GABA receptors in the insect nervous system, disrupting nerve conduction and leading to insect paralysis and death. Spinetoram J is typically one of the active components in spinetoram mixtures and exhibits high potency in agricultural pest control research.

Gonyautoxin III (GTX-III) is a paralytic shellfish toxin. It inhibits voltage-gated sodium channels at the axonal level, with an IC50 value of 14.9 nM, thereby disrupting the conduction of nerve impulses. Gonyautoxin III also exhibits cytotoxic activity against mouse neuroblastoma cells and is applicable in research on cancer and neurological diseases.

CVT-2759 is A potential partial agonist for A(1)-ADORs, and it may be useful to slow atrioventricular node conduction to reduce ventricular rate without causing the atrioventricular block, bradycardia, atrial arrhythmias, or vasodilation.

Ropivacaine mesylate, a long-acting amide local anaesthetic, is used for spinal block and effectively mitigates neuropathic pain. It achieves analgesia by reversibly inhibiting sodium ion influx in nerve fibers, thus blocking impulse conduction. Additionally, Ropivacaine acts as an inhibitor of the K2P (two-pore domain potassium channel) TREK-1, exhibiting an IC50 of 402.7 μM in COS-7 cell membranes.

Ibutilide Fumarate (U70226E) is the fumarate salt form of ibutilide, a class III antiarrhythmic agent. Ibutilide exerts its effect by activating a slow, inward, predominately sodium current rather than by blocking outward potassium currents. This results in prolongation of atrial and ventricular action potential duration and refractory periods. Ibutilide slightly decreases the sinus rate and atrioventricular (AV) conduction and produces a dose-related prolongation of the QT interval.

Mesotrin is a calcium antagonist that influences atrial and ventricular conduction, but has been linked with side effects of euphoria, ventigo and heavyheadedness.

Hexylcaine HCl also called cyclaine or osmocaine, is a short-acting local anesthetic. It acts by inhibiting sodium channel conduction. Overdose can lead to headache, tinnitus, numbness and tingling around the mouth and tongue, convulsions, inability to breathe, and decreased heart function.
