Leonurine derivative and application thereof in preparing medicine for preventing or treating ischemic cerebrovascular diseases
-
Paragraph 0050-0052, (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.

We describe a copper-catalyzed Sonogashira coupling reaction of alkyl halides with terminal alkynes under ambient conditions, efficiently providing a versatile tool for the construction of substituted alkynes. A new proline-based N,N,P-ligand is utilized to promote the transformation under a mild reaction condition. Diverse alkyl halides, such as primary and secondary (hetero)benzyl chlorides and bromides, secondary and tertiary α-bromo amides and propargylic bromide, are applicable to provide a wide array of alkynes.
