ADT derivatives in free or salt forms, organic or mineral bases, in which the ADT derivatives contain the characteristic group -S-CH2-CH2-CH(NHR)-CO- in the cyclical form <IMAGE> in which R represents an acyl group containing more than 4 carbon atoms and substituted when it is cynnamoyl, and the open form R'-S-CH -CH -CH(NHR)-C)-X-R'' in which X is oxygen or sulfur, R' and R are the same or different and are selected from the group of hydrogen and acyl radicals, R'' is hydrogen or a substituted alcoyl such that R'' has at least 2 carbon atoms when X is oxygen, R is a lower acyl and R' is hydrogen. |
