    摘要: Calixarene derivatives, their synthesis and use as chloride channel blockers are described. Preferred calixarene derivatives are of the formula: ##STR1## wherein R is an acidic group or salt thereof, such as SO.sub.3 X or R.sup.1 SO.sub.3 X where X is H or Na, and R.sup.1 is ##STR2## where m=1-2, and R.sup.3 and R.sup.4 the same or different is each H or a C.sub.1-4 alkyl, or a nitrogen-containing group of the formula ##STR3## or A, wherein R.sup.5 is a C.sub.1-4 alkyl, R.sup.6 is a C.sub.1-4 alkyl and A is ##STR4## where R.sup.7 and R.sup.8, the same or different each is H or a C.sub.1-4 alkyl, and R.sup.9 and R.sup.10, the same or different, each is H or a C.sub.1-4 alkyl; R' is H or a C.sub.1-4 alkyl; and n is an integer of 4-8, preferably 4, 6 or 8.
