What is the Emtricitabine?

The molecule Emtricitabine presents a molecular formula of C8H10FN3O3S and its IUPAC name is 4-amino-5-fluoro-1-[(2R,5S)-2-(hydroxymethyl)-1,3-oxathiolan-5-yl]pyrimidin-2-one.

Emtricitabine is a nucleoside reverse transcriptase inhibitor (NRTI) used as an antiretroviral drug in the treatment of HIV/AIDS and hepatitis B. Emtricitabine was first approved by the FDA in 2003. The most common side effects of emtricitabine are headache, fatigue, and nausea..

Emtricitabine is a nucleoside analog reverse transcriptase inhibitor (RTI). NRTIs act by competitively binding to the active site of HIV-1 reverse transcriptase (RT) and inhibiting the enzyme's DNA polymerase activity. This ultimately results in the prevention of HIV-1 DNA synthesis and the viral replication cycle..

Emtricitabine has been shown to be effective in the treatment of HIV-1 infection in adults and children over the age of 3 months. In addition, emtricitabine has also been shown to be effective in the treatment of hepatitis B infection..

The most common side effects associated with emtricitabine are headache, fatigue, and nausea. These side effects are typically mild and resolve on their own with time. More serious side effects, such as liver toxicity and pancreatitis, have been reported but are rare..

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.
