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.

U3885 UK-78282 monohydrochloride ≥98% (HPLC) UK-78282 blocks both Kv1.3 and Kv1.4. Kv1.3 and Kv1.4 are members of the Shaker family of voltage-gated potassium channels. Kv1.3 is expressed in brain and in effector memory T (Tem) cells, and Kv1.4 is expressed in brain. Both channels are involved in setting the membrane potential of neurons. In addition, Kv1.3 maintains the membrane potential for T memory cells and is up-regulated upon T cell activation, contributing to multiple immune processes and disorders. Blockers of Kv1.3 have long been sought for therapeutic benefit, and they are also valuable tools for studying the immune system. Selective blockers of Kv1.4 are desired, as there are few if any currently available. UK-78282 is valuable for immune system studies, where the absence of Kv1.4 makes it functionally selective for Kv1.3, and it has shown suppression of T cell activation. UK-78282 is also valuable for the study of Kv1.4 function.
