The invention concerns pharmaceutical compositions that contain a compound or compounds that can effectively regulate the activity of Type 5 Adenylyl Cyclase and methods for treatment of neurological diseases and disorders, as well as motor function loss therefrom, as well as treatment for cardiac conditions and diseases including conditions characterized by abnormal heart rate.
acridizinium derivatives with abasic-site containing DNA was assessed by thermal denaturation experiments with synthetic double-stranded oligonucleotides, which contained one (TX) or no abasicsite (TA). The acridizinium–adenineconjugates stabilize the DNA with the abasic position slightly more than they do the regular duplex, as indicated by the difference of the induced melting-temperature shifts between the
从相应的羧基吖啶盐制备了两种异构吖啶鎓-腺嘌呤缀合物以及三种模型化合物(即两种 9-(N-烷基羧酰胺)吖啶盐和一种 9-N-[(二甲氨基)烷基]羧酰胺}吖啶盐)。这些化合物与小牛胸腺 DNA 的相互作用通过分光光度法和粘度滴定法、LD 光谱法和 DNA 热变性实验进行了研究。吖啶鎓-腺嘌呤结合物和 N-烷基甲酰胺均以中等亲和力嵌入小牛胸腺 DNA [K ≈ 104M–1(DNA 浓度以 bp 为单位)]。相比之下,N-[3-(二甲氨基)丙基]-取代的甲酰胺在相同条件下表现出明显更高的结合常数 (K ≈ 105M–1)。吖啶鎓衍生物与含有脱碱基位点的 DNA 的关联是通过热变性实验评估的,合成双链寡核苷酸含有一个 (TX) 或不含脱碱基位点 (TA)。吖啶鎓-腺嘌呤缀合物使 DNA 的脱碱基位置比常规双链体稍微稳定,如 TX 和 TA 双链体之间诱导解链温度变化的差异所示(ΔΔTm ≈ 4

The present invention relates to derivatives and analogues of adenine, which inhibit adenylyl cyclase activity. The present invention also relates to a method of preventing and inhibiting a patient's fibroproliferative vasculopathy following vascular injury or a vascular surgical operation which includes administering to the patient, an effective amount of a compound according to the invention subsequent to a vascular injury, or subsequent to a vascular surgical operation, for one to two weeks after the injury or surgical operation, effective to treat or prevent a patient's fibroproliferative vasculopathy such as chronic allograft rejection or vascular restenosis following vascular trauma. The present invention also relates to a method for measuring the inhibition of adenylyl cyclase activity and a method for treating congestive heart failure.
