Ketones 123-129 complement C9 Homo sapiens 119-122 20470813-3 2010 The presence of a cholesterol-type side chain, which appears to play a major role in determining the biological activity, the existence of a ketone functional at C-9 is also crucial for anticancer activity whereas hydroxyl/ketone function at C-22 on the side chain did not increase cytotoxicity. Ketones 141-147 complement C9 Homo sapiens 162-165 8074523-8 1994 This pathway involves oxygenation of fluorene at C-9 to give 9-fluorenol, which is then dehydrogenated to the corresponding ketone, 9-fluorenone. Ketones 124-130 complement C9 Homo sapiens 49-52 29601190-2 2018 The treatment of the silylated enol ether 8 with a wide range of acetals in the presence of tin tetrachloride led to a the diastereoselective construction of the C-9 quaternary center of 33 new building blocks derived from the Wieland-Miescher ketone derivative 3. Ketones 244-250 complement C9 Homo sapiens 162-165
