sodium channel blocker, analgesic, ASN008, ASN 008, EN 3427, 0M9Q318030

Olisutrigine bromide (also known as ASN-008 or EN3427) is an investigational, permanently charged sodium channel blocker being studied for its potent, long-lasting analgesic (pain-relieving) properties.

Key Characteristics

  • Mechanism of Action: It acts as a membrane-impermeant sodium channel blocker. Because it carries a permanent cationic charge, it cannot easily cross healthy cell membranes on its own.
  • Targeted Delivery: It often requires a "vehicle" or a combination drug (like lidocaine) to activate specific channels (such as TRP channels), allowing olisutrigine entry into pain-sensing neurons where it becomes entrapped and blocks pain signaling.
  • Efficacy: Rodent pain models demonstrate that its analgesic effects are significantly longer-lasting than lidocaine alone.
  • Chemical Profile: Its molecular formula is C₂₅H₃₅BrN₂ with a molecular weight of 443.5 g/mol, and its CAS registry number is 1393836-45-7.

Current Status

  • Investigational Drug: It is not approved for human or veterinary medical use and remains in the research and development phase.
  • Availability: It is strictly available as a reference standard compound for laboratory and preclinical research through chemical suppliers like MedChemExpress and BenchChem.

Example 43: General Procedure M - Preparation of (R)-1,1 -dimethyl-2-[2-((indan-2-yl)(2-methylphenyl)amino)ethyl]piperidinium bromide

Alcohol 37b was synthesized as previouslydescribed (Tetrahedron 2007, 63, 3000-3005)

To a 250 mL round bottom flask was charged 2-(2-hydroxyethyl)piperidine-1-carboxylic acid tert-butyl ester 37b (5.0 g, 21.80 mmol), dichloromethane (7.50 mL), a solution of KBr (0.52 g, 4.36 mmol) in 2.0 mL of water and TEMPO (0.1 g, 0.64 mmol). The mixture was cooled to about -5 °C. A solution of NaOCl (31.1 mL, 5.25%, 24.1 mmol) was added slowly over 20 minutes while maintaining the temperature at 0 °C. The mixture was further stirred at 0°C for 20 minutes. The organic layer was separated, and the aqueous layer was extracted with

dichloromethane. The combined dichloromethane extract was washed with water (50 mL), followed by brine. After drying over MgSO4, the mixture was filtered and concentrated. The crude was purified with silica gel column chromatography to give product 38b (4.1 g, 83%) as colorless oil.

O

To a clean and dry 250 mL round bottom flask was charged sodium triacetoxyborohydride (5.59 g, 26.40 mmol), 4 A molecular sieves (10.0 g), amine 7e (7.37 g, 33.00 mmol) and dichloromethane (20.0 mL). The mixture was stirred and cooled to about 0 °C, and a solution of aldehyde 38b (5.0 g, 22.00 mmol) in 40 mL of dichloromethane was added. The mixture was then stirred further at 0 °C for about 1 hour and at ambient temperature for an additional 40 minutes. The reaction mixture was quenched with aqueous saturated NaHCO3 (100 mL). After separation of organic layer, the mixture was extracted with dichloromethane. After drying over MgSO4, the organic layer was concentrated. The crude product was purified by silica gel column chromatography to give product 40f (7.2 g, 75.3%) as colorless oil.

To a clean and dry 250 mL round bottom flask was charged lithium aluminum hydride (1.53 g, 40.27 mmol) and THF (30.0 mL). The mixture was heated to reflux. A solution of carbamate 40f (7.0 g, 16.11 mmol) in THF (40.0 mL) was added dropwise over 5 minutes. After refluxing for 15 h, the reaction mixture was cooled to 0 °C, and water (1.55 mL) was added slowly and carefully, followed by THF (100 mL) and 15% NaOH (1.55 mL). After stirring the mixture at room temperature for 1.0 h, MgSO4 was added, and the mixture was stirred further for 15 minutes. The mixture was filtered and concentrated to obtain the crude product, which was purified by silica gel column chromatography to afford product 11e (4.7 g, 84%) as pale yellow oil. Optical purity by chiral HPLC: 99.3% ee.

To a clean and dry 250 mL round bottom flask was charged diamine 11e (4.70 g, 13.49 mmol) and 1.07 M bromomethane in MTBE (126.0 mL, 134.8 mmol). After stirring at room temperature for 20 h, the reaction mixture was filtered. The solid cake was washed with MTBE to give the product (4.40 g, 73%) as white powder. Optical purity by chiral HPLC: 99.3% ee.

potassium channel activator, antiepileptic, BHV-7000; BHV7 000, BPN-25203, BPN 25203, KB-3061, KB 3061, 73H9J7RBA2

BHV-7000 is under investigation in clinical trial NCT06419608 (Efficacy and Safety Study of BHV-7000 Monotherapy in Major Depression).

Opakalim (also known as BHV-7000) is an investigational, small-molecule medication that acts as a selective activator of Kv7.2 and Kv7.3 potassium channels. Developed by Biohaven Pharmaceuticals, it targets a clinically validated pathway to regulate neuronal hyperexcitability, primarily for the treatment of epilepsy and focal seizures.

Key Characteristics

  • Mechanism of Action: It opens Kv7.2/7.3 potassium channels. This stabilizes electrical activity in the brain. Unlike older class drugs, it has minimal to no (GABA_A) receptor activity.
  • Safety Benefit: Its precision prevents typical central nervous system side effects. Patients experience much lower rates of somnolence, fatigue, and severe dizziness compared to other anti-seizure medications.
  • Administration: It is taken orally once a day. It requires no titration period before reaching therapeutic dosing.

Current Clinical Status

  • Refractory Focal Epilepsy: The drug is undergoing phase 2/3 clinical evaluation. The pivotal RISE 3 study completed patient enrollment, with high-profile top-line efficacy data anticipated in the second half of 2026.
  • Idiopathic Generalized Epilepsy (IGE): Recent clinical data highlights a three-fold prolongation in the time to a second generalized tonic-clonic seizure compared to a placebo.
  • Other Explored Indications: While it is actively tested for conditions like bipolar disorder and erythromelalgia (pain), an exploratory phase 2 trial for major depressive disorder failed to meet its primary goals.

Opakalim (INNTooltip International Nonproprietary Name, USANTooltip United States Adopted Name; developmental code names BHV-7000, BPN-25203, and KB-3061) is a highly selective Kv7.2 and Kv7.3 potassium channel opener which is under development for the treatment of bipolar disorders, epilepsy, partial epilepsies, major depressive disorder, erythromelalgia, pain, infantile spasms, and mood disorders.[1][2][3][4] It is taken orally.[1] The drug was originated by Channel Biosciences and was under development by Biohaven Pharmaceuticals or Biohaven Therapeutics.[1][2] As of April 2026, it is in phase 2/3 clinical trials for bipolar disorders, epilepsy, and partial epilepsies, phase 2 trials for major depressive disorder, and phase 1 trials for erythromelalgia and pain, whereas no recent development has been reported for infantile spasms and mood disorders.[1][2] A phase 2 trial for major depressive disorder failed to meet its primary efficacy endpoint, resulting in focus more on epilepsy instead.[3]

Abstract

The PI3K/Akt signaling pathway is a key pathway in cell proliferation, growth, survival, protein synthesis, and glucose metabolism. It has been recognized recently that inhibiting this pathway might provide a viable therapy for cancer. A series of bis(morpholino-1,3,5-triazine) derivatives were prepared and optimized to provide the highly efficacious PI3K/mTOR inhibitor 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea 26 (PKI-587). Compound 26 has shown excellent activity in vitro and in vivo, with antitumor efficacy in both subcutaneous and orthotopic xenograft tumor models when administered intravenously. The structure−activity relationships and the in vitro and in vivo activity of analogues in this series are described.

Abstract

A new, practical, and convergent synthetic route of gedatolisib, an antitumor agent, is developed on a hectogram scale which avoids the Pd coupling method. The key step is adopting 6-(4-nitrophenyl)-1,3,5-triazine-2,4-diamine and 2,2′-dichlorodiethyl ether to prepare the key 4,4′-(6-(4-nitrophenyl)-1,3,5-triazine-2,4-diyl)dimorpholine in 77% yield and 98.8% purity. Gedatolisib is obtained in 48.6% yield over five simple steps and 99.3% purity (HPLC). Purification methods of the intermediates and the final product involved in the route are given.
