    • Compounds of the formula ##STR1## and pharmaceutically acceptable salts thereof wherein: A is a bond or --OCH.sub.2 --, where the oxygen is linked to R.sup.1 ;B is --CH.sub.2 -- or when R.sup.3 is hydrogen, B may be --CH.sub.2 O-- where the oxygen is linked to the phenyl ring;R.sup.1 is an aryl group;R.sup.2 is hydrogen or lower alkyl;R.sup.3 is hydrogen; or R.sup.2 and R.sup.3 together form the group --CH.sub.2 CH.sub.2 --; andR.sup.4 is --SO.sub.3 H, --P(O.sub.2 H)R.sup.5, --P(O.sub.2 R.sup.5')R.sup.5, --PO.sub.3 H.sub.2, --PO.sub.3 HR.sup.5' or --PO.sub.3 (R.sup.5').sub.2 where R.sup.5 and R.sup.5' are independently lower alkyl. These compounds are beta.sub.3 adrenergic receptor agonists and are useful, for example, in the treatment of diabetes, obesity, achalasia, and gastrointestinal diseases.
    • 式Ⅰ化合物及其药学上可接受的盐,其中:A是一个键或-OCH 2 - ,其中氧连接到R 1; B是-CH 2 - 或当R 3是氢时,B可以是-CH 2 O-,其中氧连接到苯环上; R1是芳基; R2是氢或低级烷基; R3是氢; 或R 2和R 3一起形成基团-CH 2 CH 2 - ; R4是-SO3H,-P(O2H)R5,-P(O2R5')R5,-PO3H2,-PO3HR5'或-PO3(R5')2,其中R5和R5'独立地是低级烷基。 这些化合物是β3肾上腺素能受体激动剂,并且可用于例如治疗糖尿病,肥胖症,贲门失弛缓症和胃肠道疾病。
