Field of application
BL-1249 is a nonsteroidal anti-inflammatory drug (NSAID) and a potassium channel activator. BL-1249 exhibits more selective for the bladder (EC50 of 1.26 μM) than vascular tissue (EC50 of 21.0 μM). BL-1249 extracellular application activates all TREK subfamily members but has no effect on other K2P subfamilies. BL-1249 potently activates K2P2.1 (TREK-1) and K2P10.1 (TREK-2) with EC50 values of 5.5 μM and 8.0 μM, respectively

Description: BL-1249 is a nonsteroidal anti-inflammatory drug (NSAID) and a potassium channel activator. BL-1249 potently activates K2P2.1 (TREK-1) and K2P10.1 (TREK-2) with EC50 values of 5.5 μM and 8.0 μM, respectively. BL-1249 extracellular application activates all TREK subfamily members but has no effect on other K2P subfamilies. BL-1249 exhibits more selective for the bladder (EC50 of 1.26 μM) than vascular tissue (EC50 of 21.0 μM)[1][2].
Target: EC50: 5.5 μM (TREK-1) and 8.0 μM (TREK-2)[1]
In Vivo: BL-1249 (1 mg/kg) inhibits isovolumic bladder contractions in vivo. The short duration of the effect of BL-1249 on bladder contraction ( 30 min) is likely due to a fast elimination half-life of the compound after i.v. administration (0.69 h)[1]. BL-1249 (1 mg/kg) has little effect on mean arterial blood pressure, an observation again consistent with the in vitro bladder to vascular relaxant selectivity[1].
In Vitro: BL-1249 produces a concentration-dependent membrane hyperpolarization of cultured human bladder myocytes, assessed as either a reduction in fluorescence of the voltage-sensitive dye bis-(1,2-dibutylbarbituric acid)trimethine oxonol (EC50 of 1.26 μM) or by direct electrophysiological measurement EC50 of 1.49 μM). BL-1249 produced a concentration-dependent hyperpolarization with an EC50 of 21.0 μM in human aortic smooth muscle cells[1]. In in vitro organ bath experiments, BL-1249 produces a concentration-dependent relaxation of 30 mM KCl-induced contractions in rat bladder strips (EC50 of 1.12 μM), yet has no effect on aortic strips up to the highest concentration tested (10 μM). The bladder relaxation produced by BL-1249 is partially blocked by Ba2+ (1 and 10 mM)[1]. BL-1249 is a selective agonist of the TREK subfamily when applied extracellularly, having preferential action on K2P2.1(TREK-1) and K2P10.1(TREK-2) over K2P4.1(TRAAK) and establish that its mechanism of action relies on gating at the selectivity filter C-type gate[2].

DC73675 VU0546110 VU0546110 (VU 0546110) is a potent, selective inhibitor of the sperm-specific potassium channel SLO3 with IC50 of 1.29 uM, impairs sperm function.
DC73665 KCNQ2 activator Ebio1 Ebio1 is a selective voltage-gated potassium channel KCNQ2 activator. Ebio1 activates KCNQ2 by generating an extended channel gate with greater conductance at a saturation voltage (+50 mV).
DC70574 Lu AA41178 Lu AA41178 is a potent, pan-selective Kv7.2-7.5 opener with EC50 of 1.5, 0.6 20.5, and 37.0 uM for Kv7.2, Kv7.2/7.3, Kv7.4 and Kv7.5, respectively.Lu AA41178 displays no activity at Kv7.1 channels, has no potentiating impact on currents through GABAA ion channels, and a clean off-target profile against common cardiac ion channels.Lu AA41178 significantly increased the seizure thresholds in mice, demonstrating anticonvulsant efficacy in the maximum electroshock seizure threshold test and PTZ seizure threshold test.Lu AA41178 demonstrated antipsychotic-like activity by reducing amphetamine-induced hyperlocomotion in mice as well as lowering conditioned avoidance responses in rats, significantly reduced immobility in mouse model with antidepressant predictivity.
DC70426 GAT1508 GAT1508 (GAT-1508) is a potent, specific activator for brain-expressed GIRK1/2 channels (EC50=75 nM), specifically activates the brain GIRK1/2 over the cardiac GIRK1/4; GAT1508 is an allosteric modulator of channel–phosphatidylinositol 4,5-bisphosphate interactions. GAT1508 effectively extinguished conditioned fear in rodents and lacked cardiac and behavioral side effects, suggesting its potential for use in pharmacotherapy for post-traumatic stress disorder.

DC39089 H3B-120 H3B-120 is a competitive, selective and allosteric inhibitor of carbamoyl phosphate synthetase 1 (CPS1) with IC50 of 1.5 μM and Ki of 1.4 μM. H3B-120 exhibits anti-tumor activity.
DC28951 A2764 dihydrochloride A2764 dihydrochloride is a highly selective inhibitor of TRESK (TWIK-related spinal cord K+ channel, K2P18.1), which has moderate inhibitory effects on TREK-1 and TALK-1. A2764 dihydrochloride is more sensitive to the activated mTRESK channels (IC50=6.8 μM) than the basal current. A2764 dihydrochloride can lead to cell depolarization and increased excitability in native cells, it has the potential for probing the role of TRESK channel in migraine and nociception.
