Ro 31-8220 Mesylate is a selective inhibitor of protein kinase C (PKC) with IC50 values of 5, 24, 14, 27, and 24 nM for PKC α, PKC βI, PKC βII, PKC γ and PKC ε, respectively [1].

PKC is a monomeric Ca2+- and phospholipid-dependent Ser/Thr protein kinases and plays an important role in growth factor-activated signaling and malignant transformation.

Ro 31-8220 Mesylate is a selective inhibitor of PKC. Also, Ro 31-8220 increased growth factor-stimulated expression of c-Jun but inhibited MKP-1 and c-Fos expression. Ro-31-8220 strongly stimulated the stress-activated protein kinase JNK1 in a PKC-independent way [2]. In peripheral blood mononuclear cells, Ro 31-8220 inhibited the production of mitogen-induced interleukin (IL)-2 and IL-2-dependent T lymphoblast proliferation with IC50 values of 80 and 350 nM, respectively. Also, Ro 31-8220 (400 nM) inhibited IL-2Rα (CD25) expression by 27%, which suggested that Ro 31-8220 inhibited early and late T cell activation [3].

In rat adipocytes and L6 myotubes, RO 31-8220 activated c-Jun N-terminal kinase (JNK) and glycogen synthase (GS) and stimulated glucose incorporation into glycogen. While, RO 31-8220 inhibited the activity of extracellular response kinases 1 and 2 (ERK1/2) in a PKC-independent way [4].
