Ketones

Cerulenin is an antifungal antibiotic that inhibits fatty acid and steroid biosynthesis. It was the first natural product antibiotic known to inhibit lipid synthesis. In fatty acid synthesis, it has been reported to bind in equimolar ratio to b-keto-acyl-ACP synthase, one of the seven moieties of fatty acid synthase, blocking the interaction of malonyl-CoA. It also has the related activity of stimulating fatty acid oxidation through the activation of CPT1, another enzyme normally inhibited by malonyl-CoA. Inhibition involves covalent thioacylation that permanently inactivates the enzymes. Thes

Cyclohexylacetone (acetonylcyclohexane) is an organic compound. Cyclohexylacetone is closely related to phenylacetone being phenylacetone with the benzene ring replaced with a cyclohexane ring.

Daigremontianin is a bufadienolide. Bufadienolides are steroids and cardiac glycoside aglycones (meaning that they bind with carbohydrates to form cardiac glycosides) that are similar to cardenolides, differing only in the structure of the C-17 substituent on the D ring. This chemical has been found to be toxic in experiments on mice. It is one of five bufadienolides that have been isolated from Kalanchoe daigremontiana.

chemical compound

Droxypropine is a cough suppressant of the phenylpiperidine class.

2-Fluorodeschloroketamine (also known as '''2'-Fl-2-Oxo-PCM, fluoroketamine, and 2-FDCK''') is a dissociative anesthetic related to ketamine. Its sale and use as a designer drug has been reported in various countries. It is an analogue of ketamine where the chlorine group has been replaced by fluorine. Due to its recent emergence, the pharmacological specifics of the compound are mostly unclear, but effects are reported to be similar to its parent compound, ketamine.

4-Dehydroepiandrosterone (4-DHEA) is a steroid that is an isomer of 5-dehydroepiandrosterone.

terpenoid chemical compound

5α-Androst-2-en-17-one, known by the nickname Delta-2, is an endogenous, naturally occurring, orally active anabolic-androgenic steroid (AAS) and a derivative of dihydrotestosterone (DHT). It is a metabolite of dehydroepiandrosterone (DHEA) in the body and is also a pheromone found in elephants and boars. 5α-Androst-2-en-17-one has been sold on the Internet as a "dietary supplement". It resembles desoxymethyltestosterone (17α-methyl-5α-androst-2-en-17β-ol) in chemical structure and may act as an androgen prohormone.

Ketipramine (G-35,259), also known as ketimipramine or ketoimipramine, is a tricyclic antidepressant (TCA) that was tested in clinical trials for the treatment of depression in the 1960s but was never marketed. It differs from imipramine in terms of chemical structure only by a single ketone group, and is approximately equivalent in effectiveness as an antidepressant in comparison.

Telapristone (), as telapristone acetate (proposed brand names Proellex, Progenta; former code name CDB-4124), is a synthetic, steroidal selective progesterone receptor modulator (SPRM) related to mifepristone which is under development by Repros Therapeutics for the treatment of breast cancer, endometriosis, and uterine fibroids. It was originally developed by the National Institutes of Health (NIH), and, as of 2017, is in phase II clinical trials for the aforementioned indications. In addition to its activity as an SPRM, the drug also has some antiglucocorticoid activity.

Coronatine (COR) is a toxin produced by the bacterium Pseudomonas syringae. It is involved in causing stomata to re-open after they close in response to pathogen-associated molecular patterns, as well as interfering with the responses mediated by salicylic acid after the infection has begun. It consists of coronafacic acid (CFA), which is an analog of methyl jasmonic acid (MeJA), and coronamic acid (CMA), joined by an amide bond between the acid group of CFA and the amino group of CMA.

LY-293284, also known as 4,α-methylene-5-acetyl-DPT, is a research chemical developed by the pharmaceutical company Eli Lilly and used for scientific studies. It acts as a potent and selective 5-HT1A receptor full agonist. It was derived through structural simplification of the ergoline based psychedelic LSD, but is far more selective for 5-HT1A with over 1000× selectivity over other serotonin receptor subtypes and other targets. It has anxiogenic effects in animal studies.

Roxibolone (INN; development code BR-906; also known as 11β,17β-dihydroxy-17α-methyl-3-oxoandrosta-1,4-diene-2-carboxylic acid) is a steroidal antiglucocorticoid described as an anticholesterolemic (cholesterol-lowering) and anabolic drug which was never marketed. Roxibolone is closely related to formebolone, which shows antiglucocorticoid activity similarly and, with the exception of having a carboxaldehyde group at the C2 position instead of a carboxylic acid group, roxibolone is structurally almost identical to. The 2-decyl ester of roxibolone, decylroxibolone (development code BR-917), is

chemical compound

Arketamine (developmental code names PCN-101, HR-071603), also known as '(R)-ketamine or (R)-(−)-ketamine', is the (R)-(−) enantiomer of ketamine. Similarly to racemic ketamine and esketamine, the S(+) enantiomer of ketamine, arketamine is biologically active; however, it is less potent as an NMDA receptor antagonist and anesthetic and thus has never been approved or marketed for clinical use as an enantiopure drug. Arketamine is currently in clinical development as a novel antidepressant.
