Synthesis of 2,11-bis(methylidene)spermine, a new inhibitor of spermine oxidase
摘要:
Earlier unknown 1,12-diamino-2,11-bis(methylidene)-4,9-diazadodecane, which may be considered as an enzyme-activated inhibitor of spermine oxidase, was synthesized in 6 steps starting from 2-chloromethyl-3-chloropropene-1 in a high yield. Application of newly synthesized spermine analogue for the inhibition of spermine oxidase was discussed.

The present invention relates to a method of effecting immunosuppression in a patient in need thereof comprising administering to said patient an effective immunosuppressive amount of certain 5'-amine substituted adenosine analogs.
The adenosine derivatives represented by the following formula: ##STR1## and the pharmaceutically acceptable salts thereof wherein R is H or C.sub.1 -C.sub.7 alkyl, Q is the moiety of the formula ##STR2## wherein V is H or --COOH X is H, F, Cl, Br, and Z is H, F, Cl, or Br. These compounds are inhibitors of S-adenosylmethione decarboxylase and are useful for treating parasitic infections.

derivatives of spermidine and N1-Ас-spermidine, i.e., 1,8-diamino-2-methylidene-4-azaoctane (2-Met-Spd) and N1-(acetyl)-1,8-diamino-2-methylidene-4-azaoctane (N1-Ас-2-Met-Spd), respectively. Target compounds were obtained each in seven steps with high overall yields starting from the commercially available 2-chloromethyl-3-chloropropene-1. Possible application of newly synthesized spermidine analogs for
