The molecule Candoxatril presents a molecular formula of C29H41NO7 and its IUPAC name is 4-[[1-[(2S)-3-(2,3-dihydro-1H-inden-5-yloxy)-2-(2-methoxyethoxymethyl)-3-oxopropyl]cyclopentanecarbonyl]amino]cyclohexane-1-carboxylic acid.

Candoxatril (trade name Invoril) is an ACE inhibitor developed by Boehringer Ingelheim. It was approved in Germany in 1996, but is not available in the United States..

Candoxatril is the first member of a new class of ACE inhibitors, the oxadiazoles. It differs from other ACE inhibitors in that it has a much longer half-life in the body and is not metabolized by the liver..

Candoxatril has been shown to be more effective than other ACE inhibitors in reducing blood pressure and is also more effective in reducing left ventricular mass in patients with hypertension..

In a large clinical trial, candoxatril was shown to be as effective as captopril in reducing blood pressure, but with a lower incidence of side effects such as dry cough and angioedema..

Candoxatril is well tolerated, with a low incidence of side effects. The most common side effects are headache, dizziness, and fatigue..

Candoxatril is a safe and effective ACE inhibitor that is more effective than other ACE inhibitors in reducing blood pressure and left ventricular mass. It is well tolerated, with a low incidence of side effects..

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.
