1,3-Propanediyl compounds

Spermidine is a polyamine compound () originally isolated from semen and also found in ribosomes and living tissues and has various metabolic functions in organisms.

Spermine is a polyamine involved in cellular metabolism that is found in all eukaryotic cells. The precursor for synthesis of spermine is the amino acid ornithine. It is an essential growth factor in some bacteria as well. It is found as a polycation at physiological pH. Spermine is associated with nucleic acids and is thought to stabilize helical structure, particularly in viruses. It functions as an intracellular free radical scavenger to protect DNA from free radical attack. Spermine is the chemical primarily responsible for the characteristic odor of semen.

1,3-Propanediol is the organic compound with the formula . This 3-carbon diol is a colorless viscous liquid that is miscible with water.

Aliskiren (brand names Tekturna and Rasilez) is the first in a class of drugs called direct renin inhibitors. It is used for essential (primary) hypertension. While used for high blood pressure, other better studied medications are typically recommended due to concerns of higher side effects and less evidence of benefit.

Iloperidone, sold under the brand name Fanapt among others, is an atypical antipsychotic for the treatment of schizophrenia and bipolar I disorder.

1,3-Diaminopropane, also known as , is a simple diamine with the formula H2N(CH2)3NH2. A colourless liquid with a fishy odor, it is soluble in water and many polar organic solvents. It is isomeric with 1,2-diaminopropane. Both are building blocks in the synthesis of heterocycles, such as those used in textile finishing, and coordination complexes. It is prepared by the amination of acrylonitrile followed by hydrogenation of the resulting aminopropionitrile.

1,3-Propanedithiol is the chemical compound with the formula HSCH2CH2CH2SH. This dithiol is a useful reagent in organic synthesis. This liquid, which is readily available commercially, has an intense stench.

Dronedarone, sold under the brand name Multaq, is a class III antiarrhythmic medication developed by Sanofi-Aventis. It was approved by the US Food and Drug Administration (FDA) in July 2009. Besides being indicated in arrhythmias, it was recommended as an alternative to amiodarone for the treatment of atrial fibrillation and atrial flutter in people whose hearts have either returned to normal rhythm or who undergo drug therapy or electric shock treatment i.e. direct current cardioversion (DCCV) to maintain normal rhythm. It is a class III antiarrhythmic drug. The FDA label includes a claim fo

1,3-Dichloropropane is a compound of chlorine, hydrogen, and carbon. It may be found as a contaminant in soil fumigants containing 1,3-dichloropropene. It has low acute toxicity.

Pitolisant, sold under the brand name Wakix among others, is a medication used for the treatment of excessive daytime sleepiness in adults with narcolepsy. It is an inverse agonist of the histamine H3 receptor. It represents the first commercially available medication in its class, so that the U.S. Food and Drug Administration (FDA) declares it a first-in-class medication. Pitolisant enhances the activity of histaminergic neurons in the brain that function to improve a person's wakefulness. It was approved by the European Medicines Agency (EMA) in March 2016 for narcolepsy with or without cata

1,3-Dibromopropane is an organobromine compound with the formula (CH2)3Br2. It is a colorless liquid with sweet odor. It is used in organic synthesis to form C3-bridged compounds such as through C-N coupling reactions.

Norspermidine is a polyamine of similar structure to the more common spermidine. Norspermidine has been found to occur naturally in some species of plants, bacteria, and algae.

chemical compound

1-Bromo-3-chloropropane is an organohalogen compound with the formula Br(CH2)3Cl. It is a colorless liquid, produced by free-radical addition of hydrogen bromide to allyl chloride. It is used as an alkylating agent to install the –(CH2)3Cl and –(CH2)3– groups. For example, it is a precursor to 4-chlorobutyronitrile.

Ensaculin (KA-672) is a drug from the coumarin family, which has been researched as a potential treatment for dementia. It acts on a number of receptor systems, being both a weak NMDA antagonist and a 5HT1A agonist. Animal studies have shown promising nootropic effects, although efficacy in humans has yet to be proven. It was well tolerated in human trials, with the main side effect being orthostatic hypotension (low blood pressure upon standing).

Sesamodil is a calcium channel blocker.

ZM447439 is an aurora inhibitor.
