<p>Hydroquinone derivatives useful as an intraocular pressure decreasing agent, an antihypertensive agent and a free radical scavenger, represented by general formula (I) or (II), or pharmacologically acceptable salts thereof. In formula (I), B1 and B2 may be the same or different and each stands for a group selected from the group consisting of a hydrogen atom, a halogen atom, a hydroxyl group, a lower alkoxy group and a carboxyl group which may be at any position of the benzene ring (but may be at other positions of the benzene ring when W is a nitrogen atom); CH3 is at the position 2 or 3; and Ws may be the same or different and each represents a nitrogen or carbon atom. In formula (II), R1, R2, R3 and R4 may be the same or different and each represents a group selected from a hydrogen atom, a lower alkyl group and a lower alkoxy group; and B1 and B2 are each as previously defined.</p> |
