Hydroxyurea

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

What is the Hydroxyurea?

The molecule Hydroxyurea presents a molecular formula of CH₄N₂O₂ and its IUPAC name is hydroxyurea.

Hydroxyurea (HU) is a medication that has been used to treat cancer and sickle cell disease. It is a member of the class of drugs known as hydroxyurea agents. Hydroxyurea is thought to work by decreasing the production of certain substances that are involved in the development of cancer and sickle cell disease..

Hydroxyurea was first approved by the US Food and Drug Administration (FDA) in 1967 for the treatment of cancer. It is currently approved for the treatment of several types of cancer, including leukemia, melanoma, and ovarian cancer. It is also approved for the treatment of sickle cell disease..

Hydroxyurea is typically taken orally, in the form of a capsule or tablet. The dose and frequency of hydroxyurea vary depending on the condition being treated..

Hydroxyurea is generally well-tolerated. The most common side effects are skin rashes and low blood counts. Hydroxyurea can also cause other more serious side effects, including liver damage, kidney damage, and gastrointestinal ulcers..

Hydroxyurea is a potentially dangerous medication and should be used only under the supervision of a healthcare provider. Patients should be sure to follow their healthcare provider's instructions carefully and to report any side effects..

Molecule descriptors

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.

Physico-Chemical properties

LogP and topological polar surface area (TPSA) values were estimated using Open Babel software.

The n-octanol/water partition coeficient (K_ow) data is applied in toxicology and drug research. K_ow 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(K_ow) (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 Ų are required. Thus, molecules with a polar surface area greater than 140 Ų tend to be poorly permeable to cell membranes.
