Product Description
Picamilon is an orally bioactive gamma-aminobutyric acid analogue with nootropic properties. Picamilon can improve rat epilepsy models and promote the correction of pancreatic dysfunction in Alloxan induced rat diabetes models.
Nicotinoyl-GABA (CAS#: 34562-97-5), also known as Picamilon, is an orally bioactive gamma-aminobutyric acid analogue with nootropic properties. It is a prodrug of GABA that is able to cross the blood-brain barrier and then is hydrolyzed into GABA and nicotinic acid (niacin). Nicotinoyl-GABA is often used as a nootropic supplement and is believed to have cognitive-enhancing effects. It is also reported to possess anxiolytic and vasodilatory properties. The compound is commonly found in dietary supplements and is utilized for its potential benefits on cognitive function and neurological health. It has the molecular formula C10H12N2O3 and a molecular weight of 208.21.
Biological Activity I Assay Protocols (From Reference)
Targets
γ-aminobutyric acid/GABA derivative; GABA prodrug
Nicotinoyl-GABA is a prodrug that targets the central nervous system through delivery of its two active components: GABA (gamma-aminobutyric acid) and nicotinic acid (niacin). GABA is the primary inhibitory neurotransmitter in the brain, and its receptor activation produces anxiolytic and sedative effects. Nicotinic acid is a vitamin that acts as a vasodilator and has effects on lipid metabolism. By combining these two molecules, Nicotinoyl-GABA can deliver GABA to the brain more effectively than GABA itself, which cannot cross the blood-brain barrier. The compound's nootropic properties are attributed to the combined effects of GABA and nicotinic acid in the brain.
ln Vitro
Nicotinoyl-GABA is an antioxidant agent in neuroprotection treatment. It can improve rat epilepsy models and promote the correction of pancreatic dysfunction in Alloxan induced rat diabetes models. The compound's antioxidant properties contribute to its neuroprotective effects. As a GABA analogue, it may modulate neuronal excitability through GABA receptor activation. The nicotinic acid component provides vasodilatory effects that may improve cerebral blood flow. The combined effects of these two active components contribute to the compound's nootropic and neuroprotective activities.
ln Vivo
Picamilon (PM) intraperitoneally (20 or 50 mg/kg) Picamilon (20 or 50 mg/kg; intraperitoneally) In constructed models of Picrotoxin-induced time, picamilon greatly lowers both the frequency and duration of spike wave discharges (SWD)[2]. Oral Picamilon (250 mg/kg)
Nicotinoyl-GABA improves rat epilepsy models and promotes the correction of pancreatic dysfunction in Alloxan induced rat diabetes models. This demonstrates the compound's potential for treating neurological and metabolic disorders. As an orally bioactive compound, it can be administered conveniently. Its ability to cross the blood-brain barrier allows it to exert central effects. The compound's anxiolytic and vasodilatory properties suggest additional therapeutic applications for anxiety disorders and cardiovascular conditions.
Enzyme Assay
No specific non-cell assay protocol is available for Nicotinoyl-GABA. As a prodrug, its hydrolysis to GABA and nicotinic acid can be studied in vitro using plasma or tissue homogenates. The rate of hydrolysis can be measured by HPLC or LC-MS to determine the conversion kinetics. Receptor binding assays for GABA receptors or nicotinic acid targets could be used to assess the activity of the hydrolyzed products. However, these would measure the activity of the metabolites rather than the parent compound itself.
Cell Assay
No specific cell-based assay protocol is available for Nicotinoyl-GABA. For neuroprotection studies, neuronal cell lines or primary neurons are treated with Nicotinoyl-GABA followed by exposure to oxidative stress or excitotoxic insults. Cell viability, ROS production, and markers of apoptosis are measured. GABA receptor activation can be assessed by measuring intracellular calcium levels or electrophysiological recordings in GABA receptor-expressing cells. The compound's antioxidant activity can be evaluated by measuring cellular oxidative stress markers.
Animal Protocol
Animal/Disease Models: Alloxan-induced rat diabetes model [3]
Doses: 250 mg/ kg
Route of Administration: po (oral gavage)
Experimental Results: Inhibition of NLRP3 activity, immunopositive pancreatic cell area Dramatically diminished to (21,30 ± compared to the value in the untreated animal group (75,19±7,69% ), respectively (5,44) and (39,31±5,24)%. Promote the correction of pancreatic dysfunction during alloxan-induced diabetes by inhibiting the activation of NLRP3 inflammasome in pancreatic cells.
No specific animal protocol is available for Nicotinoyl-GABA. For epilepsy studies, standard models such as pentylenetetrazole (PTZ)-induced seizures or kindling models are used. The compound is administered orally, and seizure parameters (latency, duration, severity) are recorded. For diabetes studies, Alloxan-induced diabetic rats are treated with Nicotinoyl-GABA, and blood glucose, insulin levels, and pancreatic function are assessed. Behavioral tests may also be performed to evaluate anxiolytic and cognitive effects.
ADME/Pharmacokinetics
No detailed pharmacokinetic data is publicly available for Nicotinoyl-GABA. The compound has a molecular weight of 208.21 and formula C10H12N2O3. It is soluble in DMSO at 33 mg/mL (158.49 mM). As a prodrug, it is hydrolyzed into GABA and nicotinic acid. The compound is orally bioactive and can cross the blood-brain barrier, indicating favorable absorption and distribution properties. Comprehensive pharmacokinetic studies would be required to determine absorption, distribution, metabolism, and excretion parameters.
Toxicity/Toxicokinetics
No detailed toxicology data is publicly available for Nicotinoyl-GABA. As a dietary supplement ingredient, it has been used in various formulations with a generally favorable safety profile. However, comprehensive toxicological evaluation would be required for therapeutic development. The compound's metabolism to GABA and nicotinic acid suggests that its safety profile would be related to the effects of these metabolites. High doses of nicotinic acid can cause flushing and other side effects, which should be considered in safety assessments. The compound is for research use only.

Additional Infomation
Pikamilon has been shown to increase blood flow to the cerebral cortex of conscious rats and rabbits. Increased blood flow was observed with intravenous, intraperitoneal and systemic administration. Topical application of pycamilone significantly dilates pial arterioles. Dilation mainly occurs in arterioles with an initial diameter of 10-20 micrometers. The dilating effect of pycamilone decreases with increasing diameter of pial arterioles. [1]
In rats, seizures were induced by repeated injections of Pikamilon (PTX) (intraperitoneal injection every 30 minutes, with an initial dose of 0.9 mg/kg and subsequent doses of 0.7 mg/kg). Pikamilon (PM) and isopiamilone (IPM) were administered intraperitoneally 30 minutes before PTX injection. Following pre-administrative injection of PM and IPM, epileptiform activity (EFA) recorded from brain structures was classified into two types: one type showed only spike-and-slow-wave discharges (SWD) (61.3%), and the other type showed regular cortical spike-and-wave activity accompanied by transient SWD (38.7%). In the first type of EFA rats, the frequency and duration of SWD were significantly reduced after injection of PM and IPM at a dose of 50 mg/kg. In the second type of EFA rats, even injection of smaller doses (20 mg/kg) of the drugs reduced the intensity of SWD. IPM was more effective as a protective anticonvulsant. [2]
