  Trequinsin, a potent new antihypertensive vasodilator in the series of 2-(arylimino)-3-alkyl-9,10-dimethoxy-3,4,6,7-tetrahydro-2H-pyrimido[6,1-a]isoquinolin-4-ones

  摘要：

  Series of 3-substituted-9,10-dimethoxy-3,4,6,7-tetrahydro-2H-pyrimido [6,1-a]isoquinoline-2,4-diones and 2-substituted-9,10-dimethoxy-6,7-dihydro-4H-pyrimido [6,1-a]isoquinolin-4-ones were synthesized and tested for blood pressure lowering properties in anesthetized normotensive cats and conscious spontaneously hypertensive rats. Several compounds in the 2-(arylamino)-9,10-dimethoxy-6,7-dihydro-4H-pyrimido [6,1-a]isoquinolin-4-one series display a high order of activity. The most active compounds are the alkyl derivatives of the 2-mesitylamino/2-mesitylimino tautomeric forms. The 2-(mesitylimino)-3-methyl analogue trequinsin is a potent antihypertensive agent and displays a hemodynamic profile characteristic of an arteriolar dilator. It is also a potent inhibitor of both cAMP phosphodiesterase and platelet aggregation.

  Disclosed herein are α7β1 integrin modulatory agents and methods of using such to treat conditions associated with decreased α7β1 integrin expression or activity, including muscular dystrophy. In one example, methods for treating a subject with muscular dystrophy are disclosed. The methods include administering an effective amount of an α7β1 integrin modulatory agent to the subject with muscular dystrophy, wherein the α7β1 integrin modulatory agent increases α7β1 integrin expression or activity as compared to α7β1 integrin expression or activity prior to treatment, thereby treating the subject with muscular dystrophy. Also disclosed are methods of enhancing muscle regeneration, repair, or maintenance in a subject and methods of enhancing α7β1 integrin expression by use of the disclosed α7β1 integrin modulatory agents. Methods of prospectively preventing or reducing muscle injury or damage in a subject are also disclosed.
