SF1670 shows potent cytotoxicity in HBEC, PC-3, H1299 cells with IC50 of 5 μM, 10 μM, 44 μM, respectively. In a mouse aortic ring matrigel angiogenesis model, SF1670 stimulates the angiogenic processes. SF1670 augments chemoattractant-elicited PtdIns(3,4,5)P3 signaling in neutrophils and enhances neutrophil functions.
In vivo
Pretreatment of SF1670 (500 nM i.v.) augments bacteria-killing capability in neutropenic mice in both peritonitis and bacterial pneumonia, and decreases the mortality of neutropenia-related pneumonia.
