Electric Literature of 33100-27-5. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 33100-27-5, Name is 1,4,7,10,13-Pentaoxacyclopentadecane. In a document type is Patent, introducing its new discovery.
ETHER DERIVATIVES HAVING 5-LIPOXYGENASE INHIBITORY ACTIVITY
The invention concerns ether derivatives of the formula I Q1?X?Ar?Q2 wherein Q1 is an optionally substituted 9-, 10- or 11-membered bicyclic heterocyclic moiety containing one or two nitrogen heteroatoms and optionally containing a further heteroatom selected from nitrogen, oxygen and sulphur; X is oxy, thio, sulphinyl or sulphonyl; Ar is optionally substituted phenylene, pyridinediyl, pyrimidinediyl, thiophenediyl, furandiyl, thiazolediyl, oxazoiediyl, thiadiazoiediyl or oxadiazolediyl; and Q2 is selected from the groups of the formulae II and III: wherein R1 is hydrogen, (2-5C)alkanoyl or optionally substituted benzoyl; R2 is (l-4C)alkyl; and R3 is hydrogen or (l-4C)alkyl; or R2 and R3 are linked to form a methylene, vinylene, ethylene or trimethylene group; or a pharmaceutically-acceptable salt thereof; processes for their preparation; pharmaceutical compositions containing them and their use as 5-lipoxygenase inhibitors.
