17181170-3	2006	The corresponding C-7 furan analogs were prepared and it was found that the 3,5-substituted furan analog had increased activity compared to that of the 2,5-substituted furan isomer.	furan	22-27	complement C7	Homo sapiens	18-21	
7224721-4	1981	The results suggest that both ring C of morphinans and morphines and the furan ring of morphines contribute to binding to the allosteric site; so does increase in the size of the N-alkyl group, but alkylation at C-6 or C-7 is unfavorable for such binding.	furan	73-78	complement C7	Homo sapiens	219-222
