Novel organic trithio oxides and method for the preparation thereof

A method of inhibiting the aggregation of blood platelets, comprising applying thereto a blood platelet aggregation inhibiting amount of at least one compound of the formula:

• R.sup.1 --X--R--X.sup.1 --R.sup.1
• wherein R is selected from --CH.sub.2 CH.dbd.CH--, ##STR75## and CH.sub.2 ;
• X is selected from ##STR76## X.sup.1 is selected from --S--S--, ##STR77## and, each R.sup.1 is independently selected from substituted and unsubstituted lower alkyl, lower alkenyl, lower alkynyl, phenyl and lower alkylphenyl wherein the substituents are independently selected from carboxyalkyl, alkoxy, alkylthio, amine, alkylamino and acyl;
• provided when R is --CH.sub.2 CH.dbd.CH--, X is ##STR78## and X.sup.1 is --S--S--, then R.sup.1 is not in both instances --CH.sub.2 CH.dbd.CH.sub.2, and further provided that the total number of carbon atoms of said R.sup.1 group when substituted with carboxyalkyl does not exceed ten and that the carboxy of said carboxyalkyl includes the esters or alkali metal salts thereof.
