Bioactive small molecules are organic compounds that have a low molecular weight (900 daltons). Most pharmaceutical drugs are small molecules. Larger structures such as nucleic acids, proteins, and many polysaccharides are not small molecules.
Terpendole I is a polar analog of a rare family of indolediterpenes isolated from Albophoma yamanashiensis, first reported by Omura and colleagues at the Kitasato Institute, Japan in 1995. Terpendole I is a weak inhibitor of ACAT (acylCoA:cholesterol...
