Medicinal Thiols: Current Status and New Perspectives

In organic chemistry, a thiol , or thiol derivative, is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The −SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl (−OH) group of an alcohol), and the word is a blend of "thio-" with "alcohol". WebSep 11, 2024 · Thiols can be defined as a sulfur analogue of alcohols. In a simpler way, it is an organic compound consisting of compounds with a sulfur atom. It is also referred to as mercaptan.
