Enprostil is a synthetic prostaglandin designed to resemble dinoprostone. Enprostil was found to be a highly potent inhibitor of gastric HCl secretion. It is an analog of prostaglandin E2 but unlike this prostaglandin, which binds to and activates all four cellular receptors viz., EP1, EP2, EP3, and EP4 receptors, enprostil is a more selective receptor agonist in that it binds to and activates primarily the EP3 receptor. Consequently, enprostil is expected to have a narrower range of actions that may avoid some of the unwanted side-effects and toxicities of prostaglandin E2. A prospective mult

In biochemistry, wybutosine (yW) is a heavily modified nucleoside of phenylalanine transfer RNA that stabilizes interactions between the codons and anti-codons during protein synthesis. Ensuring accurate synthesis of protein is essential in maintaining health as defects in tRNA modifications are able to cause disease. In eukaryotic organisms, it is found only in position 37, 3'-adjacent to the anticodon, of phenylalanine tRNA. Wybutosine enables correct translation through the stabilization of the codon-anticodon base pairing during the decoding process.

DMCM (methyl 6,7-dimethoxy-4-ethyl-β-carboline-3-carboxylate) is a drug from the β-carboline family that induces anxiety and convulsions by acting as a negative allosteric modulator of GABAA receptors — functionally opposite to benzodiazepines and related drugs which are positive allosteric modulators — and is used in scientific research for these properties to test new anxiolytic and anticonvulsant medications, respectively. It has also been shown to produce analgesic effects in animals, which is thought to be the drug's induced panic reducing the perception of pain.

Riodipine (INN; brand names Foridon and Ryosidine) is a calcium channel blocker.

Advantame is a non-caloric artificial sweetener and aspartame analog by Ajinomoto. By mass, it is about 20,000 times sweeter than sucrose and about 110 times sweeter than aspartame. It has no notable off-flavors when compared to sucrose and tastes sweet a bit longer than aspartame and is chemically more stable. It can be blended with many other natural and artificial sweeteners.

chemical compound

Indorenate (TR-3369), is a tryptamine derivative which acts as an agonist at the 5-HT1A, 5-HT1B and 5-HT2C serotonin receptors. It has anxiolytic, antihypertensive and anorectic effects, predominantly through action at 5-HT1A, but with some contribution from the 5-HT1B and 5-HT2C subtypes, and possibly some other non-serotonergic targets also.

chemical compound

Rauwolscine, also known as isoyohimbine, α-yohimbine, and corynanthidine, is an alkaloid found in various species within the genera Rauvolfia and Corynanthe (including Pausinystalia). It is a stereoisomer of yohimbine. Rauwolscine is a central nervous system stimulant, a local anesthetic and a vague aphrodisiac.

A-232 is an organophosphate nerve agent. It was developed in the Soviet Union under the FOLIANT program and is one of the group of compounds referred to as Novichok agents that were revealed by Vil Mirzayanov. A-232 is reportedly slightly less potent as a nerve agent compared to some of the other compounds in the series such as A-230 and A-234, having similar potency to the older nerve agent VR. However it proved to be the most versatile agent as it was chemically stable and remained a volatile liquid over a wide temperature range, making it able to be used in standard chemical munitions witho

group of enantiomers

Difluoropine (O-620) is a stimulant drug synthesised from tropinone, which acts as a potent and selective dopamine reuptake inhibitor. Difluoropine is unique among the tropane-derived dopamine reuptake inhibitors in that the active stereoisomer is the (S) enantiomer rather than the (R) enantiomer, the opposite way round compared to natural cocaine. It is structurally related to benztropine and has similar anticholinergic and antihistamine effects in addition to its dopamine reuptake inhibitory action.
