Trospium

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

What is the Trospium?

The molecule Trospium presents a molecular formula of C25H30NO3+ and its IUPAC name is [(1R,5S)-spiro[8-azoniabicyclo[3.2.1]octane-8,1'-azolidin-1-ium]-3-yl] 2-hydroxy-2,2-diphenylacetate.

Trospium is a molecule that belongs to the class of quinuclidine alkaloids. It belongs in the roots of the plant Trophia longifolia and has been used in traditional Chinese medicine for centuries. Trospium has a variety of pharmacological effects, including anticholinergic, antiarrhythmic, and antispasmodic activity. It is also a potent agonist of the M1 muscarinic acetylcholine receptor. The exact mechanism of action of trospium is not fully understood, but it is thought to work by inhibiting the action of acetylcholine at the muscarinic receptors. Trospium has a long history of use in China for the treatment of gastrointestinal disorders. It is approved for the treatment of overactive bladder in China and Europe, and is currently being investigated for the treatment of other urinary disorders such as urinary incontinence and urinary frequency..

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.
