Described herein is the use of a substantially pure form of an oxidized polyamine, and especially spermine dialdehyde, in the treatment of tissue grafts or other organs for transplantation. The compounds and treatment are especially useful in treating grafts for bone marrow transplants, whether they be allogeneic or autograft transplants.
摘要:
Intermediate compounds (formula [III]and [IV]) useful as starting materials for the synthesis of amino acid derivatives which have renin inhibitory activity and which are useful as remedies for hypertension are prepared stereoselectively in high yield, without requiring complicated process steps. In this method, by reaction of .alpha.-amino aldehyde derivative [I] and compound [II] in the presence of BF.sub.3.OEt.sub.2, as shown in the following reaction formula, .alpha.-amino-.beta.-hydroxy-.delta.-ketone derivative [III] is prepared, and furthermore, by reducing it as required, compound [IV] is obtained: ##STR1## (where R.sup.1 is a protective group on the amino group, R.sup.2 is a lower alkyl group which may be branched, and R.sup.4 is a cyclohexyl group or phenyl group).
