Rilmazafone
Rilmazafone (リスミー, Rhythmy, previously known as 450191-S) is a water-soluble prodrug developed in Japan. Once metabolized, rilmazafone is converted into several benzodiazepine metabolites that have sedative and hypnotic effects. These metabolites induce impairment of motor function and have hypnotic properties. Rilmazafone is not a benzodiazepine, since there is no benzene ring fused with a diazepine ring in the compound; in fact, the parent drug has no diazepine ring. It is therefore not classified as a benzodiazepine in several countries, including the United States, where it is not designated a controlled substance. Rilmazafone has no effects on benzodiazepine receptors itself, nor does it produce any psychoactive effects prior to metabolism. However, once inside the body it is metabolized by aminopeptidase enzymes in the small intestine to form the principal active benzodiazepine 8-chloro-6-(2-chlorophenyl)-''N'',''N''-dimethyl-4''H''-1,2,4-triazolo ,5-a1,4]benzod ...

Alprazolam Triazolobenzophenone
Alprazolam triazolobenzophenone is a chemical compound which can be both a synthetic precursor and a prodrug for the benzodiazepine derivative alprazolam. At neutral pH it readily cyclizes to alprazolam, while in acidic conditions alprazolam undergoes a ring-opening reaction back to the triazolobenzophenone. A series of related acyl derivatives was researched in the 1980s as injectable water-soluble prodrugs of alprazolam, but were never developed for medical use. Subsequently, this compound has been detected as a designer drug, first being identified from a seizure in Spain in March 2014.

Japanese Inventions
This is a list of Japanese inventions and discoveries. The Japanese have made contributions across a number of scientific and technological domains. In particular, the country has played a crucial role in the digital revolution since the 20th century, with many modern revolutionary and widespread technologies in fields such as electronics and robotics introduced by Japanese inventors and entrepreneurs. Arts ;Comic book :Adam L. Kern has suggested that '' kibyoshi'', picture books from the late 18th century, may have been the world's first comic books. These graphical narratives share with modern manga humorous, satirical, and romantic themes. Some works were mass-produced as serials using woodblock printing. ; Folding hand fan :In ancient Japan, the first hand fans were oval and rigid fans, influenced greatly by Chinese fans. The earliest visual depiction of fans in Japan dates back to the 6th century AD, with burial tomb paintings showed drawings of fans. The folding fan was in ...

GABAA Receptor Positive Allosteric Modulators
In pharmacology, GABAA receptor positive allosteric modulators are positive allosteric modulator (PAM) molecules that increase the activity of the GABAA receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system. Upon binding, it triggers the GABAA receptor to open its chloride channel to allow chloride ions into the neuron, making the cell hyperpolarized and less likely to fire. GABAA PAMs increase the effect of GABA by making the channel open more frequently or for longer periods. However, they have no effect if GABA or another agonist is not present. Unlike GABAA receptor agonists, GABAA PAMs do not bind at the same active site as the γ-Aminobutyric acid (GABA) neurotransmitter molecule: they affect the receptor by binding at a different site on the protein. This is called allosteric modulation. In psychopharmacology, GABAA receptor PAMs used as drugs have mainly sedative and anxiolytic effects. ...

Chlorobenzenes
Chlorobenzene is an aromatic organic compound with the chemical formula C6H5Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals. Uses Historical The major use of chlorobenzene is as an intermediate in the production of herbicides, dyestuffs, and rubber. Chlorobenzene is also used as a high-boiling solvent in industrial applications as well as in the laboratory. Chlorobenzene is nitrated on a large scale to give a mixture of 2-nitrochlorobenzene and 4-nitrochlorobenzene, which are separated. These mononitrochlorobenzenes are converted to related 2-nitrophenol, 2-nitroanisole, bis(2-nitrophenyl)disulfide, and 2-nitroaniline by nucleophilic displacement of the chloride, with respectively sodium hydroxide, sodium methoxide, sodium disulfide, and ammonia. The conversions of the 4-nitro derivative are similar. Chlorobenzene once was used in the manufacture of pesticides, most notably DDT, by reaction with ...

Acetamides
Acetamide (systematic name: ethanamide) is an organic compound with the formula CH3CONH2. It is the simplest amide derived from acetic acid. It finds some use as a plasticizer and as an industrial solvent. The related compound ''N'',''N''-dimethylacetamide (DMA) is more widely used, but it is not prepared from acetamide. Acetamide can be considered an intermediate between acetone, which has two methyl (CH3) groups either side of the carbonyl (CO), and urea which has two amide (NH2) groups in those locations. Acetamide is also a naturally occurring mineral with the IMA symbol: Ace. Production Laboratory scale Acetamide can be produced in the laboratory from ammonium acetate by dehydration: : H4CH3CO2] → CH3C(O)NH2 + H2O Alternatively acetamide can be obtained in excellent yield via ammonolysis of acetylacetone under conditions commonly used in reductive amination. It can also be made from anhydrous acetic acid, acetonitrile and very well dried hydrogen chloride gas, using a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GL-II-73
GL-II-73 (GL-ii-073) is a benzodiazepine derivative related in chemical structure to compounds such as midazolam and adinazolam. It is described as an α5 preferring positive allosteric modulator of the benzodiazepine site of GABAA receptors, with weaker activity at α2 and α3 and no significant affinity for the α1 subtype. In animal tests it was found to produce effects consistent with antidepressant, anxiolytic and nootropic actions.

Tablet (pharmacy)
A tablet (also known as a pill) is a pharmaceutical oral dosage form (''oral solid dosage'', or OSD) or solid unit dosage form. Tablets may be defined as the solid unit dosage form of medicament or medicaments with suitable excipients. It comprises a mixture of active substances and excipients, usually in powder form, pressed or compacted from a powder into a solid dose. Tablets are prepared either by molding or by compression. The excipients can include diluents, binders or granulating agents, glidants (flow aids) and lubricants to ensure efficient tabletting; disintegrants to promote tablet break-up in the digestive tract; sweeteners or flavours to enhance taste; and pigments to make the tablets visually attractive or aid in visual identification of an unknown tablet. A polymer coating is often applied to make the tablet smoother and easier to swallow, to control the release rate of the active ingredient, to make it more resistant to the environment (extending its shelf li ...
