BI-9627
Based on 4 publication(s) in Google Scholar
BI-9627, a chemical probe, is a potent sodium-hydrogen exchanger isoform 1 (NHE1) inhibitor (IC50 = 6 and 31 nM in intracellular pH recovery (pHi) and human platelet swelling assays). BI-9627 displays >30-fold selectivity against NHE2 and with no measurable inhibitory activity against the NHE3 isoform. BI-9627 decreases autophagy in HTR-8/SVneo cells. BI-9627 can significantly reduce the pHi of human sperm and partially reverse the effect of DMA. BI-9627 prolongs Ca2+ recovery time in KO hiPSC-CMs. BI-9627 shows low DDI (agent-agent interaction) potential, excellent pharmacokinetics in rat and dog, and remarkably potent activity in the isolated heart model of ischemia-reperfusion injury.

BI-9627 (Compound 60) exhibits the most potent inhibition of NHE1 among all tested compounds with IC50 of 6 and 31 nM in pHi assay and platelet swelling assay[1].
BI-9627 (10-100 nM, 0-80 min) provides a significantly beneficial effect on left-ventricular end diastolic pressure, preventing much of the increase seen postreperfusion for the vehicle control in the Langendorff isolated perfused rat heart model[1].
BI-9627 (50 nM, 2 h) leads to a significant decrease in LC3-II/I ratio in HTR-8/SVneo cells as well as human trophoblast cells, suggesting a decrease in autophagy[2].
BI-9627 (100 nM, 24 h) reverses the abnormalities in Ca2+-transient-related parameters in KO hiPSC-CMs[4].
BI-9627 (100 nM, 7 d) elevates diastolic Ca2+ levels and prolongs Ca2+ recovery time in KO hiPSC-CMs[4].
