Equilin is one of the active components of estrogens used in estrogen replacement therapy. This compound is used as a sulfate conjugate in drug Premarin. Equili is an inhibitor of 17beta-hydroxysteroid dehydrogenase type 1 (17beta-HSD1), a key enzyme responsible for elevated levels of 17beta-estradiol (E2) in breast tumor tissues. Thus equilin reduce the E2 levels in breast tissues and hence the reduce risk of estrogen-dependent breast cancer.

Quinpirole (LY 171,555) is a psychoactive drug and research chemical which acts as a selective D2 and D3 receptor agonist. Quinpirole is the most widely used D2 agonist in in vivo and in vitro studies. Specific quinpirole binding in rat brain was saturable, and dependent on temperature, membrane concentration, sodium concentration and guanine nucleotides. Saturation analysis revealed high affinity binding characteristics (KD = 2.3 nM) which were confirmed by association-dissociation kinetics. The regional distribution of [3H]quinpirole binding sites roughly paralleled the distribution of [3H]spiperone binding sites, with greatest densities present in the striatum, nucleus accumbens and olfactory tubercles. A variety of drugs, most notably monoamine oxidase inhibitors (MAOls), inhibit the binding of [3H]quinpirole, but not [3H]spiperone or [3H](-)N-n-Propylnorapomorphine, in rat striatal membranes by a mechanism that does not appear to involve the enzymatic activity of MAO. Clinically antidepressant MAOIs exhibited selectivity between sites labeled by [3H]quinpirole and [3H]spiperone as did a number of structurally related propargylamines and N-acylethylenediamine derivatives and other drugs such as debrisoquin and phenylbiguanide. Quinpirole has been shown to increase locomotion and sniffing behavior in mice and induces compulsive behavior symptomatic of obsessive compulsive disorder in rats.

TS-410 (Amelometasone), is a topical anti-inflammatory steroid. Amelometasone lotion - external steroid preparation - is marketed in Japan.

Dexfosfoserine (Phosphoserine, L-Serine-O-Phosphate, O-Phosphoserine), the most abundant phosphoamino acid in the eukaryotic phosphoproteome, is not encoded in the genetic code but synthesized posttranslationally. Dexfosfoserine is an agonist of the group III metabotropic glutamate receptors. This endogenous compound inhibits neural stem cells proliferation and promotes survival of nascent neurons thus it has potential therapeutic value in addition to its basic utility as a probe for dissecting molecular mechanisms underlying neurogenesis.

There is a few information about DEXTIOPRONIN. It is an R isomer of N-(2-Mercaptopropionyl)-glycine (MPG), a synthetic aminothiol antioxidant, that is used in the treatment of cystinuria, rheumatoid arthritis, liver and skin disorders.

Cimaterol is a chemically stable nonselective agonist β1-, β2-, and β3-adrenoceptors. Cimaterol is used in sport as a stimulant and a fat burner that assists bodybuilders and strength athletes to get rid of body fats. Aside from shedding off fats, another benefit for using cimaterol for athletes is a boost in strength as well as an increase in muscle size or lean body mass. The increase in muscle size has been seen in previous animal studies when cimaterol is used. However, the reason behind the muscle gain is not identified yet, but the body has a very different response compared from taking in anabolic steroids. Experts in the field are saying that the increased nitrogen retention, that is known to cause by cimaterol, maybe the reason behind the muscle gain. Another great thing about Cimaterol is that, it can improve blood flow.

Cilostamide (also known as OPC 3689) is a selective inhibitor of type III phosphodiesterases: PDE3A and PDE3B, which inhibits thrombin-induced platelet aggregation. Elevating intracellular cAMP has been shown to inhibit platelet function. cAMP interferes with platelet-activating signals, which leads to aggregation inhibition, but the precise mechanism is unclear. It is known, that inhibition of Akt phosphorylation leads to inhibition of phosphorylation of glycogen synthase kinase 3-beta (GSK-3beta), which is an effector of Akt. However, cAMP-elevating agents’ stimulated GSK-3beta phosphorylation at Ser9. The cAMP-elevating agent cilostamide did not directly affect the enzyme activity of PI3-kinase, and thus it has two effects on PI3K signaling: inhibition of Akt phosphorylation independent of PKA. And stimulation of GSK-3beta phosphorylation dependent on PKA.

Information in the literature related to the biological and/or pharmacological properties of molracetam is absent.

Pirenperone, a quinazoline derivative, is a selective antagonist at serotonin receptor 2A binding sites. The liposoluble compound pirenperone has been studied in a variety of behavioral tests including the sensitive d-lysergic acid diethylamide (LSD) cue discrimination assay, in which it served as a potent LSD-antagonist. Pirenperone also proved to be an effective antagonist of serotonin-mediated behavioral responses including the head twitch response thought to be mediated by serotonin receptors.

Caprindolol, also known as SDZ 21009, is a beta-adrenoceptor blocker with affinity for serotonin (5-HT1A and 5-HT1B receptors.
