Aniracetam Synthesis 02
Aniracetam (brand names Draganon, Sarpul, Ampamet, Memodrin, Referan), also known as ''N''-anisoyl-2-pyrrolidinone, is a racetam which is sold in Europe as a prescription drug. It is not approved by the Food and Drug Administration for use in the United States as a prescription medication or dietary supplement. Despite the FDA's lack of approval, the drug is readily available over-the-counter in the US as a dietary supplement. Pharmacology Aniracetam has been shown to positively modulate the AMPA receptor. When ingested orally aniracetam is quickly broken down via first pass hepatic metabolism. The primary metabolites of aniracetam are ''N''-anisoyl-GABA, (70–80%), 2-Pyrrolidinone and ''p''-anisic acid (20–30%). Plasma concentrations are generally in the 5–15 ''μ''g/L range for aniracetam and 5–15 mg/L range for ''N''-anisoyl-GABA, a pharmacologically-active metabolite, during the first few hours after oral administration of the drug. These two plasma speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oral Administration
Oral administration is a route of administration where a substance is taken through the mouth. Per os abbreviated to P.O. is sometimes used as a direction for medication to be taken orally. Many medications are taken orally because they are intended to have a systemic effect, reaching different parts of the body via the bloodstream, for example. Oral administration can be easier and less painful than other routes, such as injection. However, the onset of action is relatively low, and the effectiveness is reduced if it is not absorbed properly in the digestive system, or if it is broken down by digestive enzymes before it can reach the bloodstream. Some medications may cause gastrointestinal side effects, such as nausea or vomiting, when taken orally. Oral administration can also only be applied to conscious patients, and patients willing and able to swallow. Terminology ''Per os'' (; ''P.O.'') is an adverbial phrase meaning literally from Latin "through the mouth" or "by mouth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anisoyl Chloride
Anisoyl chloride (also called methoxybenzoyl chloride) is an acyl halide, specifically an aromatic acyl chloride, and may be formed from anisic acid by replacing a hydroxyl group of the carboxylic acid with a chloride group. There are three isomers: the ''ortho-'', ''meta-'', and ''para-'' forms. Their structures differ in the arene substitution pattern—the location of the methoxy In organic chemistry, a methoxy group is the functional group consisting of a methyl group bound to oxygen. This alkoxy group has the formula . On a benzene ring, the Hammett equation classifies a methoxy substituent at the ''para'' position as ... group on the ring as compared to the acyl halide.

Nootropics
Nootropics ( , or ) (colloquial: smart drugs and cognitive enhancers, similar to adaptogens) are a wide range of natural or synthetic supplements or drugs and other substances that are claimed to improve cognitive function or to promote relaxation, particularly boosting mood, executive functions, attention, memory, creativity, or motivation in healthy individuals. The use of cognition-enhancing supplements by healthy individuals in the absence of a medical indication spans numerous controversial issues, including the ethics and fairness of their use, concerns over adverse effects, and the diversion of prescription drugs for non-medical uses. Nonetheless, the international sales of cognitive- or mood-enhancing supplements have continued to grow over time and in 2012 reached 0.69 billion. With sales supported by global health trends, the market is expected to reach US$33.85 billion by the year 2030, at a CAGR of 14.8%. While most nootropics are not regulated, there are othe ...

AMPA Receptor Positive Allosteric Modulators
AMPA receptor positive allosteric modulators are positive allosteric modulators (PAMs) of the receptor (AMPR), a type of ionotropic glutamate receptor which mediates most fast synaptic neurotransmission in the central nervous system. Medical applications AMPAR PAMs have cognition- and memory-enhancing and antidepressant-like effects in preclinical models, and have potential medical applications in the treatment of cognitive impairment (e.g., cognitive symptoms in schizophrenia, mild cognitive impairment), dementia (e.g., Alzheimer's disease), depression, and for other indications. They can broadly be divided into low-impact and high-impact potentiators, with high-impact potentiators able to produce comparatively more robust increases in AMPAR activation. However, high-impact AMPAR PAMs can cause motor coordination disruptions, convulsions, and neurotoxicity at sufficiently high doses, similarly to orthosteric AMPAR activators (i.e., active/glutamate site agonists).

Standard For The Uniform Scheduling Of Medicines And Poisons
The Standard for the Uniform Scheduling of Medicines and Poisons (SUSMP) is an Australian legislative instrument produced by the Therapeutic Goods Administration (TGA)., subsection 4A. Before 2010, it was known as the ''Standard for the Uniform Scheduling of Drugs and Poisons'' (''SUSDP'').. The SUSMP classifies drugs and poisons into different Schedules signifying the degree of control recommended to be exercised over their availability to the public.. , the most recent version is the ''Poisons Standard October 2022''. The Schedules are referred to under State and Territory legislation for regulatory purposes. Although each State and Territory has its own laws, the vast majority of medicines and poisons are classified according to the SUSMP to achieve uniform national regulation. Schedules Schedule 1 Schedule 1 is blank. Schedule 1 does not currently contain any medicines or poisons. Schedule 2: Pharmacy Medicine Schedule 2 (S2) drugs and poisons, otherwise known ...

Thionyl Chloride
Thionyl chloride is an inorganic compound with the chemical formula . It is a moderately volatile, colourless liquid with an unpleasant acrid odour. Thionyl chloride is primarily used as a chlorinating reagent, with approximately per year being produced during the early 1990s, but is occasionally also used as a solvent. It is toxic, reacts with water, and is also listed under the Chemical Weapons Convention as it may be used for the production of chemical weapons. Thionyl chloride is sometimes confused with sulfuryl chloride, , but the properties of these compounds differ significantly. Sulfuryl chloride is a source of chlorine whereas thionyl chloride is a source of chloride ions. Production The major industrial synthesis involves the reaction of sulfur trioxide and sulfur dichloride: This synthesis can be adapted to the laboratory by heating oleum to slowly distill the sulfur trioxide into a cooled flask of sulfur dichloride. :SO3 + SCl2 -> SOCl2 + SO2 Other methods includ ...

Triethylamine
Triethylamine is the chemical compound with the formula N(CH2CH3)3, commonly abbreviated Et3N. It is also abbreviated TEA, yet this abbreviation must be used carefully to avoid confusion with triethanolamine or tetraethylammonium, for which TEA is also a common abbreviation. It is a colourless volatile liquid with a strong fishy odor reminiscent of ammonia. Like diisopropylethylamine (Hünig's base), triethylamine is commonly employed in organic synthesis, usually as a base. Synthesis and properties Triethylamine is prepared by the alkylation of ammonia with ethanol: :NH3 + 3 C2H5OH → N(C2H5)3 + 3 H2O The pKa of protonated triethylamine is 10.75,David Evans Research Group and it can be used to prepare buffer solutions at that pH.
