The invention relates to 2,2-dimethylchroman-3-ol derivatives of the formula: ##STR1## in which: A, between N and CO, represents the group --CH.dbd.CH--E.dbd.CH-- or the group ##STR2## Z represents a halogen or a cyano, acetyl, trifluoroacetyl, nitro, alkylthio, carboxyl, phosphono, dial-koxyphosphoryl or alkoxycarbonyl group, the alkylthio and alkoxy groups containing from 1 to 3 carbon atoms; E represents a nitrogen atom or a group C(R.sub.4); R.sub.1 represents hydrogen, a methyl group or a hydroxyl group and R.sub.2 and R.sub.3 each independently represent hydrogen or a methyl group, it being possible for only one of the substituents R.sub.1, R.sub.2 and R.sub.3 to be methyl; and R.sub.4 represents a hydrogen atom, a halogen atom, a methyl group or a hydroxyl group; and to the pharmaceutically acceptable salts of the phosphono or carboxyl group. These derivatives have an antiarrhythmic, antiasthma and antihypertensive activity.
该发明涉及公式为2,2-二甲基色苷基-3-醇衍生物的化合物:##STR1##其中:A,在N和CO之间,代表--CH.dbd.CH--E.dbd.CH--基团或者##STR2##基团;Z代表卤素或氰基、乙酰基、三氟乙酰基、硝基、烷基硫基、羧基、膦酸基、二烷氧基磷酰基或烷氧羰基基团,烷基硫基和烷氧基基团含有1至3个碳原子;E代表氮原子或C(R.sub.4)基团;R.sub.1代表氢、甲基或羟基,R.sub.2和R.sub.3各自独立地代表氢或甲基,其中R.sub.1、R.sub.2和R.sub.3的取代基中只有一个可能为甲基;R.sub.4代表氢原子、卤素原子、甲基或羟基;以及磷酸酯或羧基的药用盐。这些衍生物具有抗心律失常、抗哮喘和降压活性。
