- The Total Synthesis of Spermine Alkaloid Kukoamine Bimesylate
-
The first total synthesis of kukoamine B bimesylate was completed from 1,4-diaminobutane dihydrochloride in 12 steps with a 11.4% overall yield, and all the steps could be carried out at a kilogram scale. The cyano groups were used as the precursor of amino groups to avoid the competitive reaction delicately. The aza-Michael addition reaction, amidation and hydrogenation of the cyano group sequence was streamlined as a general approach towards the synthesis of polyamine structures.

- SALTS OF KUKOAMINE B, PREPARATION METHOD AND USE THEREOF
-
Salts of kukoamine B, their preparation method and their pharmaceutical use in preparation of drugs for preventing and treating sepsis. Experiments indicate that salts of kukoamine B have a good effect on antagonizing the key factors inducing sepsis, and can be used in the preparation of drugs for preventing and treating sepsis. Under the current circumstances of the lack of effective measures for the treatment of sepsis in clinical practice, the medicinal formulations, which comprise the salts of kukoamine B, pharmaceutically acceptable carrier and/or diluent, provide a new approach for the prevention and treatment of sepsis.

- Efficient synthesis of orthogonally protected spermidine and norspermidine derivatives
-
Several orthogonally protected spermidine and norspermidine derivatives have been synthesized via cyanoethylation of monoprotected 1,4-butanediamine (putrescine) or 1,3-propanediamine followed by protection of their secondary amino groups and final reduct
