Amobarbital

A summary of the most common chemical descriptors (InChI Key and SMILES codes) for Amobarbital are summarized together with 3D and 2D structures and relevant physico-chemical properties.

What is the Amobarbital?

The molecule Amobarbital presents a molecular formula of C11H18N2O3 and its IUPAC name is 5-ethyl-5-(3-methylbutyl)-1,3-diazinane-2,4,6-trione.

Amobarbital is a drug that was first synthesized in Germany in 1904. It is a member of the barbiturate class of drugs, which are central nervous system depressants. Amobarbital is used as a sedative, hypnotic, and anticonvulsant. It was formerly used as an anesthetic, but its use has declined due to its potential for causing respiratory depression. Amobarbital has a half-life of about two hours and is metabolized by the liver..

Other names (synonyms)

IUPAC nomenclature provides a standardized method for naming chemical compounds. Although this system is widely used in chemistry, many chemical compounds have also other names commonly used in different contexts. These synonyms can come from a variety of sources and are used for a variety of purposes.

One common source of synonyms for chemical compounds is the common or trivial names, assigned on the basis of appearance, properties, or origin of the molecule.

Another source of synonyms are historical or obsolete names employed in the past, however replaced nowadays by more modern or standardized names.

In addition to common and historical names, chemical compounds may also have synonyms that are specific to a particular field or industry.

LogP and topological polar surface area (TPSA) values were estimated using Open Babel software.

The n-octanol/water partition coeficient (Kow) data is applied in toxicology and drug research. Kow values are used, to guess the environmental fate of persistent organic pollutants. High partition coefficients values, tend to accumulate in the fatty tissue of organisms. Molecules with a log(Kow) (or LogP) greater than 5 are considered to bioaccumulate.

TPSA values are the sum of the surface area over all polar atoms or molecules, mainly oxygen and nitrogen, also including hydrogen atoms.

In medicinal chemistry, TPSA is used to assess the ability of a drug to permeabilise cells.

For molecules to penetrate the blood-brain barrier (and act on receptors in the central nervous system), TPSA values below 90 Å2 are required. Thus, molecules with a polar surface area greater than 140 Å2 tend to be poorly permeable to cell membranes.
