b-Zeacarotene is a carotenoid molecule that is found in plants and animals. It has been shown to have an inhibitory effect on protein synthesis. b-Zeacarotene is a reactive compound that can react with other compounds to form new compounds, such as reaction products of the polyene type. In bacteria, transcriptional regulation of genes involved in carotenoid biosynthesis has been shown to be inhibited by b-zeacarotene.

Tetrahydro-1-naphthoic acid is a toxic chemical that is used in the synthesis of various organic compounds. It is an organic acid that has a pungent odor and can cause irritation of the nose and throat. When heated, it evolves toxic fumes of hydrogen chloride gas and phosgene. Tetrahydro-1-naphthoic acid reacts with metal hydroxides to form metal tetrahydro-1-naphthoates, which have useful properties as catalysts in organic reactions. Tetrahydro-1-naphthoic acid has been used as a growth regulator in plants and animals. It binds to DNA at the C–H site, preventing protein synthesis and cell division by inhibiting RNA synthesis.

2,2'-Dipyridylamine is a compound that belongs to the group of low-energy compounds. It has been shown to have antimicrobial activity against bacteria and fungi and has been demonstrated to be effective in treating cancer cells. 2,2'-Dipyridylamine is a molecule with two nitrogen atoms, which are bound by hydrogen bonds. This compound also contains methoxy groups that are coordinated by the nitrogen atoms. The structural analysis shows that there are three open coordination sites for metal ions that can bind with the nitrogen atoms. The x-ray diffraction data show that 2,2'-dipyridylamine crystallizes in a monoclinic system with an orthorhombic unit cell.

S-(+)-1-Aminotetrahydronaphthalene is an amido derivative that is the enantiomer of S-(-)-1-amino-N,N'-diphenylformamide. It has been shown to have anti-obesity effects in mice by increasing energy expenditure and reducing food intake. S-(+)-1-Aminotetrahydronaphthalene also inhibits the release of fatty acids from adipose tissue, which may be due to its ability to suppress lipolysis. The molecular mechanism for these effects is not yet known, but it is thought that the amide group on this compound interacts with certain protein surfaces and steric interactions are involved in its activity.

Nicotine 1'-oxide is a metabolite of nicotine which is a naturally occurring alkaloid. Nicotine 1'-oxide is produced by the oxidation of nicotine and can be found in tobacco smoke, as well as in the urine of humans. Nicotine 1'-oxide has been shown to have enzyme inhibiting properties, and has been shown to decrease insulin-stimulated glucose transport rate in human liver cells. This product also has potential use as a stabilizer for pharmaceuticals or other organic substances, and can inhibit demethylation reactions that may lead to carcinogenesis. Nicotine 1'-oxide may also play a role in the transport of chemicals across membranes.

L-Aspartic acid alpha-tert-butyl ester is a synthetic amino acid that can be used as a substrate for the synthesis of L-cysteine in the presence of selenomethionine. This compound is an auxotroph and cannot be synthesized by the body, so it must be obtained through diet or supplementation. It has been shown to have anti-cancer properties, which may be due to its role in regulating cell proliferation, apoptosis, and angiogenesis. L-Aspartic acid alpha-tert-butyl ester may also inhibit colon cancer cells by preventing them from recycling proteins. This compound was shown to inhibit HCT116 human colon cancer cells in both experimentally and computationally studies. Additionally, this molecule was seen to induce tumor regression in mice with colitis by inhibiting eukaryotic protein synthesis. This inhibition was found to be mediated through a trifluoromethyl group on the molecule's

Cholesterol 2,4-Dichlorobenzoate (CDCB) is a crystalline solid that forms the polymorphs of monoclinic, orthorhombic, and hexagonal. This compound has been traditionally used as a food additive in many commercial products to improve flavor and stability. The membranes of bacteria are composed of cholesterol 2,4-dichlorobenzoate. The nature of the compound is such that it can exist as two different conformers: the trans conformer with the chloro group on one side and the benzoate on the other or the cis conformer with both chloro groups on one side. The monoclinic form has two conformational isomers: propionate and acetate. These isomers are not distinguishable by X-ray diffraction but can be distinguished by infrared spectroscopy.
