Product name:HBT1 Other name:YDL223C CAS No.:489408-02-8 Molecular formula:C16H17F3N4O2S Molecular weight:386.40 Purity:99.0% Appearance:Light yellow solid Packing :1kg per bag 25kg per drum Application:nootropics 3.Product introduction HBT1 binds to the ligand-binding domain of the α-amino-3-hydroxy-5-methyl-4- isoxazolepropion , ic acid receptor (AMPA-R) in a glutamate-dependent manner. This means that HBT1 is a molecule that can only bind to specific sites on the AMPA-R protein when glutamate is present, and that this binding helps regulate the protein's activity. AMPA receptors are expressed throughout the central nervous system and play important roles in neuronal communication, sensory processing, and learning, memory, and synaptic plasticity. AMPA receptors are major contributors to excitatory neurotransmission, mediate rapid, rapid desensitized excitation of many synapses, and are involved in early responses of synaptic regions to glutamate. AMPA receptors are often coexpressed with NMDA receptors at synapses, and together they promote synaptic plasticity processes involved in learning, memory, excitotoxicity, and neuroprotection. Brain-derived neurotrophic factor (BDNF) is a neurotrophic factor that plays an important role in the maintenance and expansion of neurons, and has potent and numerous effects on the proliferation, differentiation, survival and death of neuronal and non-neuronal cells, Acts as a neurotransmitter modulator and contributes to neuronal plasticity for learning and memory. It is therefore essential to the health and well-being of the nervous system. An increase in BDNF may prove helpful in the treatment and prevention of many diseases. 4.Applications HBT1 is a novel AMPA receptor enhancer with lower agonism compared with LY451395 and OXP1, it induces the production of brain-derived neurotrophic factor (BDNF), and it shows little effect in primary neurons Agitation. HBT1 binds to the ligand- binding domain of AMPA-R in a glutamate-dependent manner. Together, they promote synaptic plasticity processes involved in learning, memory, excitability and neuroprotection. It can improve the cognitive ability and memory of the brain, and enhance people's learning ability.

In animal models, it has a variety of central nervous system effects. Experiments on rats demonstrate that nooglutyl exhibits pronounced vestibular- protective properties and by its antimotion activity does not rank below classic vestibular protectors, such as scopolamine and diprazine. Electrophysiological experiments on cats show that nooglutyl alters spontaneous activity in 80% of cortical neurons (somatosensory zone I and area 5 of the parietal association cortex) and considerably weakens effects caused by motion sickness: activation of single unit activity of somatosensory zone I and inhibition of neuron responses to somatic stimulation. This property of the preparation is believed to form the basis of its antimotion effect. 4.Features (1) High purity: Nooglutyl preparation can obtain high-purity products through natural extraction and fine manufacturing process. High purity means better bioavailability and fewer adverse reactions. (2) Safety: Nooglutyl is a natural product that has been proven to be safe to humans. Within the dosage range, it has no toxicity or side effects. (3) Stability: Nooglutyl preparation has good stability and can maintain its activity and effect under different environmental and storage conditions. (4) Easy to absorb: Nooglutyl preparation can be quickly absorbed by the human body, enter the blood circulation through the intestinal tract, and distribute to different tissues and organs. 5.Applications The neuroprotective properties of the positive modulator of AMPA subtype of glutamatergic receptors Nooglutyl （N－（5－oxynicotinoyl）L－glutamic acid）－the agent with nootropic and anti-hypoxic activities, were studied in the models of intracerebral post－ traumatic hematoma（hemorrhagic stroke，HS）and occlusion of the middle cerebral artery （ischemic stroke）in rats. Nooglutyl at a dose of 10 mg ／kg diminished HS-induced neurological deficit，movement coordination disturbances improved the memory in conditioned passive avoidance task and increased the survival in HS model. The volume of ischemic damage caused by the occlusion of distal fragments of the left middle cerebral artery （OMCA）was shown to be 22.51％ of ipsilateral hemisphere volume in the saline treated rats. Mexidol at adose of 50 mg/kg injected i.v. during OMCA diminished the volume of the damage up to 6.5％. These findings suggest the neuroprotective profile of Nooglutyl action.
