D-Tryptophanol is a synthetic, enantiopure, hydroxymethylated tryptamine. It is a maltobionic molecule and it can be prepared by the hydrolysis of L-tryptophan with sodium hydroxide in water. D-Tryptophanol can also be synthesized from 3,4-diaminopyridine in the presence of a base and catalytic amount of copper(II) chloride. The chemical stability of D-tryptophanol has been studied using HPLC methods. Molecular modeling studies have shown that the compound forms hydrogen bonds with its neighboring molecules and has a high affinity for binding to human liver cells. D-Tryptophanol has been found to inhibit cancer cell growth at nanomolar concentrations, making it an attractive candidate for chemotherapeutic drugs. Calixarenes are used as chiral synthons to produce racemic mixtures of D-tryptophanol that could be

R-(-)-1,2-Propanediol is a diol that is used as an additive in pharmaceutical preparations. It has been shown to inhibit the growth of several genera of bacteria and fungi, including Actinomyces, Bacillus, Clostridium, Corynebacterium, Enterobacteriaceae (Escherichia coli), Lactobacillus, Micrococcus, Mycobacteria (M. tuberculosis), Nocardia, Pseudomonas aeruginosa. R-(-)-1,2-Propanediol also inhibits the production of carbon source from glucose by inhibiting the enzyme pyruvate dehydrogenase which catalyzes the conversion of pyruvate to acetyl coenzyme A. R-(-)-1,2-Propanediol does not show any significant effect on bacterial growth when it is used at concentrations below 100mM. It has been shown that optimal reaction with R-(-)-

3,3,3-Trifluoro-1-propanol is a chemical that is used in pharmaceutical dosage formulations. It has a relatively low toxicity and is not readily absorbed through the skin. 3,3,3-Trifluoro-1-propanol has been shown to be an effective inhibitor of fatty acid oxidation and protein synthesis. The structure of this compound consists of three carbon atoms connected by single bonds to one hydrogen atom each and one fluorine atom. This molecule also contains a hydroxyl group at one end and two nitrogen atoms at the other end. These nitrogen atoms are stabilized by intramolecular hydrogen bonds with the hydrogen atoms on the hydroxyl group. 3,3,3-Trifluoro-1-propanol can be used as a cationic polymerization catalyst for perfluoroalkyls and aromatic hydrocarbons.

3-Dehydro retinol is a carotenoid that is found in the skin. It is derived from retinol, and has been shown to have antioxidant properties. 3-Dehydro retinol can be isolated from the fungus Monascus purpureus by chromatographic methods. The enzyme activities of 3-dehydroretinol are not well understood, but it has been hypothesized that chronic exposure to this compound may lead to an increase in cell proliferation or an increase in cell differentiation. 3-Dehydro retinol has also been shown to inhibit the oxidation of other molecules such as hydrogen chloride.

Ganodermanontriol is a natural compound that is extracted from the roots of Ganderma applanatum. It has potent anticomplement activity and has been shown to have transcriptional regulation activity. Ganodermanontriol binds to DNA with high affinity, which leads to inhibition of transcription and replication. Ganodermanontriol also inhibits the activity of enzymes such as protein kinase C, phosphodiesterase, and phosphatases. This inhibitory effect on these enzymes may be due to its hydroxyl group, which can donate hydrogen bonds.

Rac-1,2-bis-palmitoyl-3-chloropropanediol is a dispersive molecule that is composed of a fatty acid and a chlorinated derivative of palmitic acid. It is used to calibrate the mass spectrometer and as an internal standard in quantitative analysis. Rac-1,2-bis-palmitoyl-3-chloropropanediol reacts with electrospray ionization with a dose-dependent response. It has been shown to be toxic to kidney cells at high doses but not at low doses. This chemical has been detected in food samples after being absorbed from the gastrointestinal tract. Rac 1,2-bis-palmitoyl 3 chloropropanediol can be found in the dipalmitate form or as formic acid.

1-Tetradecanethiol is a high-resistance, detergent composition that is used in vitro to test the effects of boron nitride. This chemical has been shown to be an effective cross-linking agent for polymers and other materials. It also acts as a viscosity reducer and has low energy requirements. 1-Tetradecanethiol can be used as a cationic surfactant and as a molecule in 3-mercaptopropionic acid.
