597496-2	1977	The infrared spectra in the 1600-1800 cm-1 region clearly show the existence of a coordination interaction between the C-9 ketone oxygen function of one molecule and the central magnesium atom of another molecule.	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
