1-Benzenesulfonyl-piperidine-4-carboxylic acid ethyl ester is an inhibitor of acetylcholinesterase. It is a white solid that can be synthesized in two steps from commercially available starting materials. Inhibition of this enzyme leads to the accumulation of acetylcholine, which causes increased stimulation of nicotinic and muscarinic receptors. This drug has been shown to have IC50 values that are similar to those of the reference inhibitor donepezil. 1-Benzenesulfonyl-piperidine-4-carboxylic acid ethyl ester also interacts with sulfonyl chlorides, butyrylcholinesterase, and other proteins in a manner similar to donepezil. The molecular docking studies suggest that this compound binds competitively with the active site of acetylcholinesterase.

6,8-Dimethoxyquinoline is a quinoline derivative that has been used to synthesize a number of other drugs. It has shown activity against cancer cells in vitro and in vivo and has been shown to have an anticholinergic effect on the central nervous system. 6,8-Dimethoxyquinoline also inhibits bacterial growth and is active against Gram-positive bacteria such as Enterococcus faecalis, Staphylococcus aureus, Streptococcus pyogenes, and Bacillus subtilis. This compound binds to the enzyme carbonic anhydrase II with high affinity. The binding of 6,8-dimethoxyquinoline with carbonic anhydrase II prevents the conversion of CO2 into carbonic acid, which may lead to cell death by inhibiting respiration.

(1E)-1-Bromocyclooct-1-ene is a ligand that binds to the central metal ions in an inorganic compound. This ligand stabilizes the intermediate formed during cross-coupling reactions, which are used to synthesize organic compounds with complex structures. The kinetic of cyclooctyne and chiral compounds can be accelerated by this ligand, which is also used in polymer synthesis.

2-(Propan-2-yl)benzene-1-sulfonyl chloride is a monosubstituted, haloalkyl sulfonamide that blocks the dopamine D3 receptor. It has been shown to be effective in the treatment of Parkinson's disease (PD). 2-(Propan-2-yl)benzene-1-sulfonyl chloride binds to the dopamine D3 receptor and inhibits binding of dopamine, thereby blocking the effects of dopamine on the central nervous system. This drug has also been used as a positron emission tomography (PET) radiotracer to identify regional cerebral blood flow in patients with PD.

3-Hydroxy-N,N,3-trimethylbutanamide is a liquid at room temperature. It is an additive that can be used in the production of nitrocellulose and as a preservative for nitrate film. 3-Hydroxy-N,N,3-trimethylbutanamide decomposes on exposure to UV light to form nitric oxide. It is also used as a photoinitiator in the synthesis of polymers by free radical polymerization reactions. The liquid composition can be thermally treated to produce stable silver nanoparticles.

2-Hydrazinoquinoxaline is a potent cytotoxic agent that inhibits methionine aminopeptidase, an enzyme that regulates the synthesis of proteins. 2-Hydrazinoquinoxaline has been shown to be active against cancer cells in culture and to produce cytostatic effects in vivo. The IC50 value for 2-hydrazinoquinoxaline was found to be less than 1 μM with an ED50 of approximately 10 μM, which indicates that this drug is more potent than some other quinoxalines. 2-Hydrazinoquinoxaline is not active against bacteria, but it has been shown to inhibit the growth of P. aeruginosa in vitro.

1-tert-Butyl-1H-imidazole-2-thiol is a halogenated aromatic compound that is used as a solvent, a ligand in organometallic chemistry, and as an intermediate in the synthesis of other organic compounds. This chemical has been shown to undergo halide exchange reactions with metal ions such as magnesium chloride, aluminum chloride, and zinc chloride. It also has been shown to react with carboxylates to form 1-tert-butyl-1H-imidazole-2-carboxylate. The bond cleavage of the thiol group can be induced by reaction with iodosobenzene diacetate or hydrochloric acid. 1-tert-Butyl-1H-imidazole-2-thiol is soluble in ethers and benzene. The molecule has two thiol groups that can undergo disulfide bond formation, which may be catalyzed by copper(
