SML0543   p38 MAP Kinase Inhibitor IV ≥98% (HPLC) p38 MAP Kinase Inhibitor IV is an ATP-competitive inhibitor of p38α/β MAPK with IC50 values of 130 nM for p38α and 550 nM for p38β. It is much less active with ≤23% inhibition at 1 μM against p38γ/σ, ERK1/2, and JNK1/2/3. Shown to be more effective than SB 203580 in inhibiting LPS-induced IL-1β release from hPBMC (100% vs. 50% inhibition with 100 μM inhibitor). A recent study showed that p38 MAP Kinase Inhibitor IV could consistently and significantly enhance reprogramming and iPS cell generation from somatic cells.

Unlike estradiol (E2), PaPE-1 did not stimulate proliferation of MCF-7 breast cancer cells. Like estradiol, PaPE-1 strongly activated MAPK and mTOR pathway. Instead, it showed preferential estrogen-like activity in non-reproductive (metabolic and vascular) tissues, reducing body weight gain and fat accumulation in ovariectomized mice and accelerating repair of endothelial damage in the vascualture.

P5749 S-(+)-PD 123177 trifluoroacetate salt hydrate ≥98% (HPLC), solid S-(+)-PD 123177 is selective AT2 angiotensin receptor antagonist. The angiotensin AT2 receptor is an atypical seven transmembrane domain receptor that is coupled to activation of tyrosine phosphatase and inhibition of MAP kinase, and does not undergo agonist-induced internalization. An investigation of the occurrence and nature of AT2 receptor phosphorylation revealed that phorbol ester-induced activation of protein kinase C (PKC) in HA-AT2 receptor-expressing COS-7 cells caused rapid and specific phosphorylation of a single residue (Ser354) located in the cytoplasmic tail of the receptor. Agonist activation of AT2 receptors by angiotensin II (Ang II) also caused rapid PKC-dependent phosphorylation of Ser354 that was prevented by the AT2 antagonist, S-(+)-PD 123177, and by inhibitors of PKC. In cells coexpressing AT1 and AT2 receptors, Ang II-induced phosphorylation of the AT2 receptor was reduced by S-(+)-PD 123177 and abolished by treatment with both antagonists or with PKC inhibitors. These findings indicate that the AT2 receptor is rapidly phosphorylated via PKC during homologous activation by Ang II, and also undergoes heterologous PKC-dependent phosphorylation during activation of the AT1 receptor.

This prevents the G protein heterotrimers from interacting with receptors, thus blocking their coupling and activation. Since the Gα subunits remain in their GDP-bound, inactive state, they are unable to inactivate adenylyl cyclase or open K+ channels.
