SLx-2119(KD-025, cas 911417-87-3) is a small molecule and selective inhibitor of ROCK2 with IC50 of 105 nM; > 200 fold selecivity over ROCK1(IC50 =24 uM).
In humans, oral KD 025 diminishes STAT3 phosphorylation and pro-inflammatory cytokine production in CD4+ T cells while up-regulating phosphorylation of STAT5 in regulatory T cells, altering the immune response.
Favipiravir (cas 259793-96-9 ), also known as T-705 or Avigan, is an antiviral drug that selectively inhibits the RNA-dependent RNA polymerase of influenza virus. It is phosphoribosylated by cellular enzymes to its active form, favipiravir-ribofuranosyl-5'-triphosphate (RTP). Favipiravir is active against a broad range of influenza viruses, including A(H1N1)pdm09, A(H5N1) and the recently emerged A(H7N9) avian virus. It also inhibits influenza strains resistant to current antiviral drugs, and shows a synergistic effect in combination with oseltamivir, thereby expanding influenza treatment options.
