11677234-2	2002	Prostaglandin synthesis by cyclooxygenases-1 and -2 (COX-1 and COX-2) involves an initial oxygenation of arachidonic acid at C-11, followed by endoperoxide and cyclopentane ring formation, and then a second reaction with molecular oxygen in the S configuration at C-15.	Cyclopentanes	160-172	mitochondrially encoded cytochrome c oxidase II	Homo sapiens	63-68	
12620660-1	2003	Several heteroaromatic analogues of (2-aryl-1-cyclopentenyl-1-alkylidene)-(arylmethyloxy)amine COX-2 inhibitors, in which the cyclopentene moiety was replaced by pyrazole, thiophene or isoxazole ring, were synthesized, in order to verify the influence of the different nature of the central core on the COX inhibitory properties of these kinds of molecules.
