Jaspamycin (7-CN-7-C-Ino) does not bind with purified human PKARIα. Anti-parasite activity. Jaspamycin (7-CN-7-C-Ino) is a potent activator of PKA, binding to the R site (PKAR), with an EC50 of 6.5 nM and Kd of 8 nM in Trypanosomabrucei.
7-Methylguanosine 5’-diphosphate (7-Methyl-GDP) sodium, a cap analog, can be used in the synthesis of mRNA cap analogues[1]. 7-Methylguanosine 5’-diphosphate sodium inhibits binding of eukaryotic initiation factors to reovirus capped mRNA and complex formation involving uncapped mRNA or 18 S rRNA[1].T. brucei mRNA decapping enzyme (TbDcp2) that cleaves 7-Methylguanosine 5’-diphosphate sodium from capped RNA to generate pRNA, a substrate for TbCe1[2].
