The invention relates to compounds of the general formula (I) ##STR1## and physiologically acceptable salts, hydrates and bioprecursors thereof, in which Q represents a benzene ring in which incorporation into the rest of the molecule is through bonds at the 1- and 3- or 1- and 4- positions: Z represents one of the groups ##STR2## where X represents NCN, NSO.sub.2 Methyl, NSO.sub.2 Phenyl or CHNO.sub.2. The compounds show pharmacological activity as selective histamine H.sub.2 -antagonists.

There are disclosed substituted derivatives of amino alkane diols having the formula:
wherein
R1, R2, R3 and R4 are, e.g., hydrogen or loweralkyl;
n and m are 1 or 2;
kis 0 to 4;
is a 6-membered heterocycle containing one to three nitrogen atoms or a 5-membered heterocycle containing two to three heteroatoms selected from oxygen, sulfur, or nitrogen with the proviso that when either an oxygen or a sulfur atom is present, the remaining heteroatom(s) must be nitrogen or a substituted phenylene; E is a group having the followinp formulae:
wherein
R7 is, e.g., hydrogen or loweralkyl;
R8 is, e.g., CH2-aryl;
Z and Z' are, e.g., CN;
p is 1 or 2; and,
the physiologically acceptable, non-toxic salts thereof. These compounds are useful for the suppression of gastric acid secretions in mammals.
