, (2021/03/30)
The invention provides a leonurine derivative and application of the leonurine derivative in preparation of a medicine for preventing or treating ischemic cerebrovascular diseases. The leonurine derivative has a structure as shown in a general formula (I), wherein X is selected from O or NH; Y is selected from any one of natural amino acid, substituted amino acid or amino alcohol; Z is selected from H, proline and any substituted proline. Pharmacological experiments prove that the leonurine derivative provided by the invention has the effects of neuroprotection, cerebral infarction area reduction and animal neurobehavioral scoring, and is good in safety, so that the leonurine derivative has important significance for developing novel medicines for preventing or treating ischemic cerebrovascular diseases.

PROBLEM TO BE SOLVED: To provide peptides with reproductive- and sexual-function stimulating activity. SOLUTION: The peptides are represented by general formula: A-Thr-Lys-Pro-B-C-D-X (where A is 0, Met, Met(O), Thr, Ala, His, Phe, Lys, or Gly; B is 0, Gly, Asp, Trp, Gln, Asn, Tyr, Pro, or Arg; C is 0, Arg, Phe, Tyr, Gly, His, Pro, or Lys; D is 0, Val, Gly, Tyr, Trp, Phe, or His; and X is OH, OCH3, or NH2; where 0 represents absence of the amino acid residue; provided that if A≠0 then B ≠0 and/or C≠0 and/or D≠0, if B≠0 then C≠0 and/or D≠0, and peptides Phe-Thr-Lys-Pro-Gly, Thr-Lys-Pro-Pro-Arg and Thr-Lys-Pro-Arg-Gly are excluded).
