Abstract: New thiazolo[5,4-b]azepine compounds represented by ##STR1## wherein R.sup.1 is a hydrogen atom, an aliphatic group which may be substituted, a carboxylic acyl group which may be substituted or a sulfonic acyl group which may be substituted; R.sup.2 is a hydrogen atom, an aromatic group which may be substituted or an aliphatic group which may be substituted, which are capable of e.g., inhibiting lipoperoxide formation.

Abstract: A novel composition and method are disclosed for reducing acetaldehyde toxicity, especially for preventing and relieving hangover symptoms in humans. The composition comprises (a) a compound of the formula: ##STR1## wherein R is hydrogen or an acyl group; R' is thiol or sulfonic group; and n is an integer of 1 or 2, (b) ascorbic acid or a salt thereof and (c) a disulfide type thiamine derivative or a salt thereof. The composition is orally administered, preferably in the form of tablets.

Abstract: A novel condensed thiazole derivative of the formula [I]: ##STR1## wherein A is a single bond or CH.sub.2 ; R.sup.1 is hydrogen atom, or an optionally substituted aliphatic, carboxylic acyl or sulfonic acyl group; and R.sup.2 is hydrogen atom, or an optionally substituted aromatic cyclic or aliphatic group, or a salt thereof. The compound [I] is useful for medicines for preventing and treating various diseases such as cancer, arterial sclerosis, hepatopathy, cerebrovascular diseases, inflammatory and the like. A process of the compound of the formula [I] or a salt thereof and a pharmaceutical composition comprising the compound of the formula [I] or a pharmaceutically acceptable salt thereof as an active component are also disclosed.
