Biological properties of the C-8 substituted analogues of 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA)
Janeba, Zlatko ; Holý, Antonín ; Zídek, Zdeněk
The 9-[2-(phosphonomethoxy)ethyl]adenine (PMEA) derivatives substituted at the C-8 position of the purine moiety did not exhibited any pronounced antiviral or antimalarial activity, but both 8-hydroxy and 8-sulfanyl derivatives of PMEA possess significant immunostimulatory activities.
Modeling of nucleolar self-assembly
Blažíková, Michaela ; Heřman, P. ; Malínský, Jan
Mammalian cell nucleoli disassemble at the beginning of mitosis and reassemble again during telophase and the early G1. Dynamics of this process was studied using a model based on entropy driven self-assembly of pre-ribosomal particles generated in a single biosynthetic source. Monte Carlo simulations revealed that such model can explain formation of a large aggregate, a nucleolus, in the vicinity of the source. We examined influence of nucleoplasm properties on dynamics of the aggregate formation.
