Synthesis of various 5-alkoxymethyluracil analogues and structure–cytotoxic activity relationship study
摘要:
A number of 5-alkoxymethyluracil analogues were synthesized to evaluate their cytotoxic activity. 5-Alkoxymethyluracil derivatives 1 were prepared via known nucleophilic substitution of 5-chloromethyluracil 5 and subsequently transformed to their corresponding nucleosides 2. All prepared compounds were submitted to cytotoxic activity testing against drug sensitive and drug resistant leukaemia cells and solid tumour derived cell lines. In addition, the cytotoxic activity of 5-alkoxymethyluracil analogues 1 and 2 was compared with the previously published 5-[alkoxy(4-nitrophenyl)methyl]uracil analogues 3 and 4. Extensive structure-cytotoxic activity relationship studies are reported. (C) 2011 Elsevier Ltd. All rights reserved.
The present invention comprises novel and known purine and pyrimidine nucleoside derivatives which have been discovered to be active against hepatitis C virus (HCV). The use of these derivatives for the treatment of HCV infection is claimed as are the novel nucleoside derivatives disclosed herein.
The invention relates to mRNA therapy for the treatment of Hemophilia A. mRNAs for use in the invention, when administered in vivo, encode Factor VIII, isoforms thereof, functional fragments thereof, and fusion proteins comprising Factor VIII. mRNAs of the invention are preferably encapsulated in lipid nanoparticles (LNPs) to effect efficient delivery to cells and/or tissues in subjects, when administered thereto. mRNA therapies of the invention increase and/or restore deficient levels of Factor VIII expression and/or activity in subjects. mRNA therapies of the invention further decrease levels of toxic metabolites associated with deficient Factor VII I activity in subjects.
