lofepramine
Lofepramine, sold under the brand names Gamanil, Lomont, and Tymelyt among others, is a tricyclic antidepressant (TCA) which is used to treat depression. The TCAs are so named as they share the common property of having three rings in their chemical structure. Like most TCAs lofepramine is believed to work in relieving depression by increasing concentrations of the neurotransmitters norepinephrine and serotonin in the synapse, by inhibiting their reuptake. It is usually considered a third-generation TCA, as unlike the first- and second-generation TCAs it is relatively safe in overdose and has
fentiazac
Fentiazac is a thiazole-based nonsteroidal anti-inflammatory drug (NSAID) developed for use in joint and muscular pain. Like most other NSAIDs, it acts through inhibition of prostaglandin synthesis, via non-selective inhibition of both COX-1 and COX-2. First described in 1974, it was synthesized using the Hantzsch thiazole synthesis.

Zomepirac is an orally effective nonsteroidal anti-inflammatory drug (NSAID) that has antipyretic actions. It was developed by McNeil Pharmaceutical, approved by the FDA in 1980, and sold as the sodium salt zomepirac sodium, under the brand name Zomax. Due to its clinical effectiveness, it was preferred by doctors in many situations and obtained a large share of the analgesics market; however, it was subsequently withdrawn in March 1983 due to its tendency to cause serious anaphylaxis in a small, but unpredictable, subset of the patient population.
cycloguanil
Cycloguanil is a dihydrofolate reductase inhibitor, and is a metabolite of the antimalarial drug proguanil; its formation in vivo has been thought to be primarily responsible for the antimalarial activity of proguanil. However, more recent work has indicated that, while proguanil is synergistic with the drug atovaquone (as in the combination Malarone), cycloguanil is in fact antagonistic to the effects of atovaquone, suggesting that, unlike cycloguanil, proguanil may have an alternative mechanism of antimalarial action besides dihydrofolate reductase inhibition.
taranabant
Taranabant (codenamed MK-0364) is a cannabinoid receptor type 1 (CB1) inverse agonist that was investigated as a potential treatment for obesity due to its anorectic effects. It was developed by Merck & Co.

Etolorex was derived from phentermine, an amphetamine derivative in its own right frequently prescribed as a weight loss drug for the treatment of obesity with a positive side effect of CNS activation and energizing the patient. Etolorex, for unknown reasons, was never marketed.
laropiprant
Laropiprant (INN) was a drug used in combination with nicotinic acid to reduce blood cholesterol (LDL and VLDL) that is no longer sold, due to increases in side-effects with no cardiovascular benefit. Laropiprant itself has no cholesterol lowering effect, but it reduces facial flushes induced by nicotinic acid.
carbofenotion
Carbophenothion also known as Stauffer R 1303 as for the manufacturer, Stauffer Chemical, is an organophosphorus chemical compound. It was used as a pesticide for citrus fruits under the name of Trithion. Carbophenothion was used as an insecticide and acaricide. Although not used anymore it is still a restricted use pesticide in the United States. The chemical is identified in the US as an extremely hazardous substance according to the Emergency Planning and Community Right-to-Know Act.
drinabant
Drinabant (INN; AVE-1625) is a drug that acts as a selective CB1 receptor antagonist, which was under investigation varyingly by Sanofi-Aventis as a treatment for obesity, schizophrenia, Alzheimer's disease, Parkinson's disease, and nicotine dependence. Though initially studied as a potential treatment for a variety of different medical conditions, Sanofi-Aventis eventually narrowed down the therapeutic indications of the compound to just appetite suppression. Drinabant reached phase IIb clinical trials for this purpose in the treatment of obesity but was shortly thereafter discontinued, likel
4-chlorobenzoic acid
chemical compound
4-chlorobenzaldehyde
4-Chlorobenzaldehyde ('''p-Chlorobenzaldehyde''') is an organic compound with the formula . It is one of three isomeric monochlorinated benzaldehydes.
saclofen
Saclofen is a competitive antagonist for the GABAB receptor. This drug is an analogue of the GABAB agonist baclofen. The GABAB receptor is heptahelical receptor, expressed as an obligate heterodimer, which couples to the Gi/o class of heterotrimeric G-proteins. The action of saclofen on the central nervous system is understandably modest, because G-proteins rely on an enzyme cascade to alter cell behavior while ionotropic receptors immediately change the ionic permeability of the neuronal plasma membrane, thus changing its firing patterns. These particular receptors, presynaptically inhibit N-
fenarimol
Fenarimol, sold under the tradenames Bloc, Rimidin and Rubigan, is a fungicide which acts against rusts, blackspot and mildew fungi. It is used on ornamental plants, trees, lawns, tomatoes, peppers, eggplants, cucumbers and melons. It is mainly used to control powdery mildew. It works by inhibiting the fungus's biosynthesis of important steroid molecules (via blockade of the CYP51 enzyme).
arbaclofen placarbil
chemical compound
ibipinabant
Ibipinabant (SLV319, BMS-646,256) was designed by Jos Lange at Solvay Pharmaceuticals in 2000. Nowadays, it is an in vivo active pharmacological tool used in scientific research which acts as a potent and highly selective CB1 antagonist. It has potent anorectic effects in animals, and was researched for the treatment of obesity, although CB1 antagonists as a class have now fallen out of favour as potential anorectics following the problems seen with rimonabant, and so ibipinabant is now only used for laboratory research, especially structure-activity relationship studies into novel CB1 antagon
capsazepine
Capsazepine is a synthetic antagonist of capsaicin. It is used as a biochemical tool in the study of TRPV ion channels.
ISRIB
ISRIB (short for "integrated stress response inhibitor") is an experimental tool compound that blocks the integrated stress response, restoring the cell’s translation capacity.

fipexide
Fipexide (Attentil, Vigilor) is a psychoactive drug of the piperazine chemical class which was developed in Italy in 1983. It was used as a nootropic drug in Italy and France, mainly for the treatment of senile dementia, but is no longer in common use due to the occurrence of rare adverse drug reactions including fever and hepatitis. Fipexide is similar in action to other nootropic drugs such as piracetam and has a few similarities in chemical structure to centrophenoxine. Chemically, it is an amide union of parachlorophenoxyacetate and methylenedioxybenzylpiperazine (MDBZP), and has been show

Clinical study also suggests that mitratapide may help to reverse insulin resistance in dogs.
chlorphentermine
Chlorphentermine, sold under the brand names Apsedon, Desopimon, and Lucofen, is a serotonergic appetite suppressant of the amphetamine family. Developed in 1962, it is the para-chloro derivative of the better-known appetite suppressant phentermine, which is still in current use.

nutlins
Nutlins are a family of small molecule, cis-imidazoline analogs, which inhibit the interaction between MDM2 and tumor suppressor p53, stabilizing p53 and triggering cell death and senescence. Three nutlins were discovered in the initial small molecule screen (nutlin-1, nutlin-2, and nutlin-3), but nutlin-3 is most commonly used in anti-cancer studies. Nutlins disrupt the p53–MDM2 interaction by occupying a p53-binding pocket of MDM2. Many tumors that express normal p53 and normal or elevated levels of MDM2 may be targeted using nutlin. Nutlin-3 acts quickly in vitro, leading to increased level
