| Description | Ezetimibe, also known as zetia or ezedoc, belongs to the class of organic compounds known as monobactams. Monobactams are compounds comprising beta-lactam ring is alone and not fused to another ring. Ezetimibe is an extremely weak basic (essentially neutral) compound (based on its pKa). A beta-lactam that is azetidin-2-one which is substituted at 1, 3, and 4 by p-fluorophenyl, 3-(p-fluorophenyl)-3-hydroxypropyl, and 4-hydroxyphenyl groups, respectively (the 3R,3'S,4S enantiomer). |
