8-Fluorodibenzo[b,f] thiepine and 8-hydroxydibenzo[b,f]-thiepin-3-carboxylic acid-5-oxide compounds of formula :
where Z is thio, sulfinyl or sulfonyl; and
and their pharmaceutically salts are novel. They are used in the treatment and control of allergic conditions such as allergic asthma and are made into pharmaceutical compositions forthat purpose. The compounds are made by hydrolysing the corresponding 3-cyano compounds. The R(-) isomer of 8-fluorodibenzo[b,f] thiepin-3-carboxylic acid-5-oxide is particularly useful as an antiasthmatic.
式中的 8-氟二苯并[b,f]硫杂卓和 8-羟基二苯并[b,f]硫杂卓-3-羧酸-5-氧化物化合物:
其中 Z 为硫代、亚砜基或磺酰基;以及
及其药用盐是新型化合物。它们可用于治疗和控制过敏性疾病,如过敏性哮喘,并为此制成药物组合物。这些化合物是通过水解相应的 3-氰基化合物制成的。8-氟二苯并[b,f]硫杂卓-3-羧酸-5-氧化物的 R(-)异构体特别适用于抗哮喘。
