General description

A cell-permeable and bio-available azaindolylmethylpyridamine derivative that acts as a potent inhibitor against FMS and KIT (IC50 = 28 and 16 nM, respectively) by targeting and locking these two PDGF family receptor kinases in their inactive DGF-out conformation, while being less effective against Flt3, KDR/VEGFR2, CDC2L6/CDK11/CDK19, NTRK3/TrkC, DDR2, CDK8/cyclin C (IC50 = 91, 130, 350, 620, 700, and 710 nM, respectively) and exhibiting much reduced or little potency toward other kinases in a 400-kinase panel selectivity study (IC50 >1 µM). Shown to effectively inhibit CSF-1-induced (with RANKL as co-stimulator) osteoclast differentiation (IC50 = 170 nM), cellular FLT3-ITD, FMS, KIT phosphorylations (IC50 ranges from 20 to 250 nM), as well as FLT3-ITD-, FMS-, KIT-dependent proliferations (IC50 ranges from 92 to 380 nM), while being less effective against KDR- or wt FLT3-dependent proliferations (IC50 ranges from 1.6 to 5 µM). Orally available in rats (AUC0-∞ (h·µg/mL)/Cmax (µg/mL) = 6.4/0.63 and 46.35/3.72 post 10 mg/kg and 40 mg/kg oral dosage, respectively) and mice (AUC0-∞ (h·µg/mL)/Cmax (µg/mL) = 8.51/1.67 and 53.3/7.78 post 10 mg/kg and 40 mg/kg oral dosage, respectively) and is reported to exhibit in vivo efficacy in preventing rat MRMT-1 breast carcinoma bone metastases-caused osteolysis (30 mg/kg b.i.d.) as well as in blocking inflammation responses in several murine models, including UUO- (unilateral ureter obstruction) induced kidney inflammation (40 mg/kg b.i.d.), collagen-induced arthritis (20 to 80 mg/kg b.i.d.), LPS-induced serum IL-6 & TNF-α release (single 40 mg/kg oral dose 4.25 h before LPS), and mast cell activation-induced anaphylaxis (single 80 mg/kg oral dose 2 h before antigen stimulation).

"Apoptosis & Autophagy in Cancer: Cell Survival by Eluding Cell Death The ability of tumor cells to elude programmed cell death, also known as apoptosis, is a hallmark of most types of cancer. Similary, autophagy is a highly regulated, homeostatic degradative process where cells destroy their own components via the lysosomal machinery and recycle them for prolonged cell survival. Via extensive crosstalk with pro-apoptotic signaling pathways, autophagy can also contribute to cell death and greatly influence general cell health. Elucidating the correlation between autophagy and apoptotic cell death has become the focus of a great deal of research, particularly in tumor biology. On one hand, autophagy may induce cell death by degrading essential components; on the other hand, it may facilitate survival of cancer cells under unfavorable metabolic conditions."
