(
Elsevier Inc.
, 2013 , Article)
The successful design and synthesis of a novel Pt complex of the histone deacteylase inhibitor belinostat are reported. Molecular modelling assisted in the identification of a suitable malonate derivative of belinostat(mal-p-Bel) ...
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
(
American Society for Microbiology
, 2005 , Article)
Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ...
