, (2008/06/13)
A hydroquinone derivative useful as an intraocular pressure lowering, anti-hypertensive and radical scavenging agent represented by the following formula wherein B1 and B2 in formula (I) are the same or different and at any position on the benzene ring (when W is nitrogen, however, at any other position on the benzene ring) and each denotes a substituent selected from the group consisting of hydrogen, halogen, hydroxyl, lower alkoxyl and carboxyl, and the substituent CH3 is at position 2 or 3, and W are the same or different and each denotes a nitrogen or carbon atom. R1, R2, R3 and R4 in formula (II) are the same or different and each denotes a substituent selected from the group consisting of hydrogen, lower alkyl and lower alkoxyl, and B1 and B2 are as hereinbefore defined, or a pharmacologically acceptable salt thereof.

Hewgill, Frank R.,Greca, Bart La,Legge, Frank,Roga, Peter E.
, p. 131 - 134 (2007/10/02)
The n.m.r. spectra of a number of 2,2'-diphenoquinones imply that they have the trans-configuration.The importance of charge-separated structures in unsymmetrical quinones is discussed in relation to the formation of oxepinobenzofurans.
