The invention relates to chroman derivatives of the general formula ##STR1## wherein R.sub.1 is hydrogen, lower alkyl, substituted phenyl, phenyl, phenyl-lower alkyl, substituted phenyl-lower alkyl or lower alkyl-amino-lower alkyl; R.sub.2 is ##STR2## R.sub.3, R.sub.4, R.sub.5 and R.sub.6 each is independently selected from hydrogen, hydroxy, amino, -o-acyl, -o-lower alkyl; ##STR3## halogen, lower alkyl, or halo substituted lower alkyl; and salts and hydrates thereof. These compounds are useful as anti-inflammatory agents; for inhibition of blood platelet aggregation, as antiallergy and as antihypertensive agents.
该发明涉及一般式为##STR1##的噻吩衍生物,其中R.sub.1是氢、较低的烷基、取代苯基、苯基、苯基-较低烷基、取代苯基-较低烷基或较低烷基-氨基-较低烷基;R.sub.2是##STR2##R.sub.3、R.sub.4、R.sub.5和R.sub.6各自独立地选自氢、羟基、氨基、-o-酰基、-o-较低烷基;##STR3##卤素、较低烷基或卤素取代的较低烷基;以及其盐和水合物。这些化合物可用作抗炎药物;用于抑制血小板聚集,作为抗过敏剂和降压药物。
