The present invention relates, by way of novel industrial products which are useful in therapy, to the benzopyranone-.beta.-D-thioxyloside compounds of the formula ##STR1## in which: one of the substituents R or R' is an oxygen atom double-bonded to the corresponding cyclic carbon atom and the other is a group R.sub.1, the symbol represents a double bond conjugated to the CO group provided by one of the substituents R or R', X is a sulfur atom or an oxygen atom, R.sub.1 and R.sub.2, which are identical or different, are each a hydrogen atom, a C.sub.1 -C.sub.4 alkyl group, a halogen atom, a trifluoromethyl group or a phenyl group, it being possible for R.sub.1 and R.sub.2, taken together, to form a 7,8,9,10-tetrahydrodibenzo[b,d]pyran-6-one group or a 1,2,3,4-tetrahydro-9H-xanthen-9-one group with the benzopyranone group to which they are bonded, and Y is the hydrogen atom or an aliphatic acyl group.
本发明涉及一种有益于治疗的新型工业产品,即公式为##STR1##的苯并吡喃酮-.beta.-D-硫代木糖苷化合物,其中:R或R'的一个取代基是双键结合到相应的环状碳原子上的氧原子,另一个是R.sub.1基团,符号表示与R或R'中的一个取代基所提供的CO基团共轭的双键,X是硫原子或氧原子,R.sub.1和R.sub.2相同或不同,分别是氢原子、C.sub.1-C.sub.4烷基、卤素原子、三氟甲基或苯基,R.sub.1和R.sub.2还可以共同形成与它们结合的苯并吡喃酮基团的7,8,9,10-四氢二苯并[b,d]吡喃-6-酮基团或1,2,3,4-四氢-9H-黄酮-9-酮基团,Y是氢原子或脂肪族酰基。
