    • The invention provides histamine H 2 -antaponist compounds of formula (1):-
      and pharmaceutically acceptable salts thereof, where

      W is a 2-furanyl or 2-thienyl group optionally substituted in the 5-position with a group R 1 R 2 N(CH 2 ) a -; a 2-pyridyl group optionally substituted in the 4- or 6-position with a group R 1 R 2 N(CH 2 ) a -; a phenyl group substituted in the 3-or 4-position with a group R 1 R 2 N(CH 2 ) a -; a 4-imidazolyl group optionally substituted in the 5-position with methyl or bromine; a 2-pyridyl group optionally substituted in the 3-position with C 1-4 alkyl, C 1-4 , alkoxy, halogen, amino or hydroxy; a 2-thiazolyl group or a 2-guanidino-4-thiazolyl group;
      X is (CH 2 ) b in which b is from 3 to 6, or (CH 2 ) d S(CH 2 ) e in which dand e are the same or different and are from 1 to 3 or, when W is substituted phenyl or 2-pyridyl substituted in the 4- or 6- position with a group R 1 R 2 N(CH 2 ) a -, O(CH 2 ) t in which f is from 2 to 5;
      Z is hydrogen or C 1-4 alkyl;
      A is C 1 -C 5 alkylene or (CH 2 ) p A 1 (CH 2 ) q - where A' is oxygen or sulphur and p and q are such that their sum is from 1 to 4;
      B is an optionally substituted pyridyl, where the optional substituent is one or more C 1-4 alkyl, or C 1-4 alkoxy or hydroxy groups or halogen atoms or an N-oxo group or a phenyl group optionally substituted with one or more C 1-4 alkyl or C 1-4 alkoxy groups or halogen atoms or B is a 6-(2,3-dihydro-1,4-benzodioxinyl) or a 5-(1,3-benzodioxolyl) group or B is a 2-furanyl or 2-thienyl group optionally substituted in the 5-position with a group R 1 R 2 N(CH 2 ) a -; a phenyl group substituted in the 3- of 4-position with a group R 1 R 2 N(CH 2 ) a - or a 3-pyridyl group substituted in the 5- or 6-position or a 4-pyridyl group substituted in the 2-position by a group R 1 R 2 N(CH 2 ) a -;
      R' and R 2 can be the same or different and are hydrogen or C 1-4 alkyl or together form a 1,4-butanediyl, 1,5-pentanediyl, 1,6-hexanediyl or 1,7-heptanediyl group; and a is 1 to 4.
