What is the N-acetylhomocystein thiolactone?
The molecule N-acetylhomocystein thiolactone presents a molecular formula of C6H9NO2S and its IUPAC name is N-[(3S)-2-oxothiolan-3-yl]acetamide.
N-acetylhomocystein thiolactone (NACL) is a molecule that has potential therapeutic applications. NACL is a derivative of the amino acid homocysteine, which is a naturally occurring compound in the body. NACL is being studied for its ability to modulate the activity of enzymes involved in the metabolism of homocysteine. Additionally, NACL has been shown to have antioxidant and anti-inflammatory properties..
The exact mechanism of action of NACL is not fully understood, but it is thought to work by inhibiting the activity of homocysteine-thiolactone hydrolase (HTHL), an enzyme that breaks down homocysteine-thiolactone. This inhibition of HTHL activity results in an increase in the levels of homocysteine-thiolactone in the body. Homocysteine-thiolactone is a potent inhibitor of another enzyme, cystathionine-beta-synthase (CBS), which participes in the metabolism of homocysteine..
NACL has been shown to be effective in reducing the levels of homocysteine in the blood of rats. Additionally, NACL has been shown to reduce the severity of atherosclerosis in mice. These findings suggest that NACL may have potential as a treatment for atherosclerosis and other cardiovascular diseases..
NACL is currently being studied in clinical trials for the treatment of homocysteine-related conditions such as atherosclerosis, stroke, and Alzheimer’s disease. Additionally, NACL is being investigated as a potential treatment for cancer..

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.
