hydrophobic substituent at the N8 position. The five-membered ring of 1 can be replaced by a pyridine or isoquinoline nucleus without untoward effects. Preliminary kinetic data suggest that the type of enzyme inhibition produced by the mesoionic derivatives is similar to that observed for theophylline. Thus, several novel mesoionic ring systems display activity as inhibitors of cyclic-AMP PDE and can serve
发现介电的噻唑并嘧啶(1)和介电的1,3,4-噻二唑并嘧啶(2)的几种简单的烷基和芳烷基衍生物具有类似茶碱的活性,可作为环AMP磷酸二酯酶(PDE)的抑制剂。1的C 2 -C 3双键的还原或用N-甲基取代1或2的硫原子几乎消除了活性。最佳活性似乎与N8位的疏水取代基有关。1的五元环可以被吡啶或异喹啉核取代,而不会产生不利影响。初步的动力学数据表明,由中离子衍生物产生的酶抑制作用类型与茶碱类似。从而,
