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

What is the (R)-Mepenzolate?

The molecule (R)-Mepenzolate presents a molecular formula of C21H26NO3+ and its IUPAC name is [(3R)-1,1-dimethylpiperidin-1-ium-3-yl] 2-hydroxy-2,2-diphenylacetate.

R-mepenzolate is a molecule that is being studied for its potential therapeutic benefits. It is a chiral molecule, meaning that it has two mirror-image forms that are non-superimposable. This can make it difficult to produce and study in the laboratory. However, its potential benefits may make it worth further investigation..

R-mepenzolate is thought to be a potential treatment for gastrointestinal disorders. It works by blocking the action of acetylcholine, a chemical messenger that participes in many different processes in the body. By blocking acetylcholine, R-mepenzolate can help to reduce symptoms of diarrhea, nausea, and vomiting..

There is still much research that needs to be done on R-mepenzolate before it can be approved for use in humans. However, the molecule shows promise as a potential treatment for gastrointestinal disorders..

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.
