Description

General description

A cell-permeable, orally available quinoline derivative with anti-malarial properties. Increases intralysosomal pH and thereby impairs autophagic degradation process. Reduces metabolic activity and suppresses proliferation of human dermal fibroblasts (IC₅₀ = 30 µM). Shown to inhibit ERK1/2 phosphorylation (Thr202/Try204), but does not affect Akt and mTOR phosphorylation. Shown to directly block the binding of CXCL12 to CXCR4 and inhibit downstream effects in pancreatic cancer cells (EC₅₀ = 9.8 µM). Effectively antagonizes CXCR4-mediated cell proliferation in PANC-1, Hs-766T, and MIAPaCa-2 cells. Suppresses Toll-like receptor 9 (TLR-9)-mediated dendritic cell activation and displays anti-inflammatory properties.
