mesylaatti

Mesylaatti is a Finnish word, a Finnish translation and adaptation of the English term "mesylate." In chemistry, a mesylate is a salt or ester of methanesulfonic acid. Methanesulfonic acid, often abbreviated as MsOH, has the chemical formula CH3SO3H. The mesylate anion, CH3SO3-, is a good leaving group in organic chemistry, meaning it can easily detach from a molecule during a chemical reaction.

This property makes mesylate esters valuable intermediates in the synthesis of various organic compounds. They are often used to convert alcohols into better leaving groups, facilitating nucleophilic substitution reactions. For example, if an alcohol is treated with methanesulfonyl chloride (MsCl) in the presence of a base, it forms a mesylate ester. This mesylate ester can then react more readily with nucleophiles than the original alcohol.

In a pharmaceutical context, "mesylate" can also refer to a salt formed between a drug molecule (typically a basic compound) and methanesulfonic acid. Forming a salt with methanesulfonic acid can improve the physical properties of a drug, such as its solubility, stability, and bioavailability. Many pharmaceutical drugs are administered as mesylate salts to enhance their therapeutic efficacy. Examples of drugs that are formulated as mesylate salts include imatinib mesylate (used in cancer treatment) and tramadol mesylate (an analgesic). The term "mesylaatti" in Finnish would refer to these chemical entities, whether they are synthetic intermediates or pharmaceutical salts.
