生物活性

RO5461111 a highly specific and orally active antagonist of Cathepsin S with IC50s of 0.4 nM (human Cathepsin S) and 0.5 nM (murine Cathepsin S), respectively. RO5461111 can effectively inhibit the activation of antigen-specific T cells and B cells. RO5461111 can improve pulmonary inflammation and lupus nephritis[1][2].

IC50 & Target[1]

human Cathepsin S

0.4 nM (IC50)

murine Cathepsin S

0.5 nM (IC50)

体外研究
(In Vitro)

RO5461111 (16 h) 在 人 (RAJI) 或鼠 (A20) 细胞系中具有细胞活性,显著降低了脾脏树突状细胞的活化以及随后 CD4 T 细胞和 CD4/CD8 双阴性 T 细胞的扩增和活化[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
