Chemistry is an experimental science, category: indole-building-block, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 686747-51-3, Name is Methyl 5-nitro-1H-indole-3-carboxylate
7-Deazapurines are known to possess broad antiviral activity, however the 2?-C-methylguanosine analogue displays poor cell permeation and limited phosphorylation, thus is not an efficient inhibitor of hepatitis C virus (HCV) replication. We previously reported the 6-O-methyl entity as a prodrug moiety to increase liphophilicity of guanine nucleosides and the ProTide approach applied to 2?-C-methyl-6-O-methylguanosine has lead to potent HCV inhibitors now in clinical trials. In this Letter, we report the synthesis and biological evaluation of 2?-C-methyl-6-O-methyl-7-deaza guanosine and ProTide derivatives. In contrast to prior studies, removal of the N-7 of the nucleobase entirely negates anti-HCV activity compared to the 2?-C-methyl-6-O- methylguanosine analogues. To understand better this significant loss of activity, enzymatic assays and molecular modeling were carried out and suggested 2?-C-methyl-6-O-methyl-7-deaza guanosine and related ProTides do not act as efficient prodrugs of the free nucleotide, in marked contrast to the case of the parent guanine analogue.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. category: indole-building-block, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 686747-51-3, in my other articles.
