3-(4-Pyridyl)indole Chemical Properties,Usage,Production

Description

Two Rho-associated kinases (ROCK), ROCK1 and ROCK2, act downstream of the G protein Rho to regulate cytoskeletal stability. The ROCKs play important roles in diverse cellular functions including cell adhesion and proliferation, smooth muscle contraction, and stem cell renewal. 3-(4-Pyridyl)indole is a ROCK1 inhibitor (IC₅₀ = 25 μM) that promotes cell spreading, inhibits membrane blebbing, and induces dissolution of actin stress fibers in a wound healing assay. It also inhibits ROCK2 and PRK2, another Rho-dependent kinase, with similar potency, while inhibiting MSK-1 and PKA with relatively weaker potency.

Uses

Two Rho-associated kinases (ROCK), ROCK-I and ROCK-II, act downstream of the G protein Rho to regulate cytoskeletal stability. The ROCKs play important roles in diverse cellular functions including cell adhesion and proliferation, smooth muscle contraction, and stem cell renewal. 3-(4-Pyridyl)indole is a ROCK-I inhibitor (IC50 = 25 μM) that promotes cell spreading, inhibits membrane blebbing, and induces dissolution of actin stress fibers in a wound healing assay. It also inhibits ROCK-II and PRK2, another Rho-dependent kinase, with similar potency, while inhibiting MSK-1 and PKA with relatively weaker potency.[Cayman Chemical]

Uses

A cell-permeable indolopyridine compound that acts as a selective, ATP-competitive inhibitor of Rho kinase (ROCK) activity.

Definition

ChEBI: 3-pyridin-4-yl-1H-indole is a member of indoles.

General Description

A cell-permeable indolopyridine compound that acts as a selective, reversible, and ATP-competitive inhibitor of Rho kinase activity with an IC₅₀ of 25 μM. Does not inhibit the activation of Rho kinase nor does it affect the in vitro activities of MLCK, PKCα, and SAPK2a/p38α. Shown to be 5-fold less potent than Y-27632 (Cat. No. 688000; IC₅₀ = ~5 μM), and display a similar specificity profile as H-89 (Cat. No. 371963). Affects cell migration, inhibits blebbing (IC₅₀ = ~ 12 μM in M2 cells), and decreases stress fibers in Bulb 3T3 cells at 50 μM.

Biochem/physiol Actions

Cell permeable: yes
