(ADME) study results, ACT‐1004‐1239 is predominantly metabolized by CYP3A4. This study investigated the effect of the strong CYP3A4 inhibitor, itraconazole, on the pharmacokinetics of single‐dose ACT‐1004‐1239 in healthy male subjects. In the open‐label, fixed‐sequence DDI study, a ...
The structure of this inhibitor contains an uncharacteristically well‐ordered extended beta‐hairpin in the CDR3 region. In combination with cell‐based assays and molecular modeling, this analysis has allowed us to develop an atomic view of the VUN701‐ACKR3 interface. Th...
We found that CRP-induced P-selectin surface expression was not affected by the tested antibody/inhibitor (Supplementary Fig. 18). Further, the addition of recombinant CXCL12 to platelets prior to activation does not modulate CRP-induced P-selectin degranulation. When we performed this flow ...
This was further corroborated by results obtained with bafilomycin A1, an inhibitor of vacuolar-type H+-ATPases. Previous studies showed that low endosomal pH is needed for chemokine dissociation from ACKR3 and efficient receptor recycling and resensitization50,51. We observed that treatment with b...
cells. Static adhesion assay with THP-1 cells was performed as follows: HCAECs were transfected with 30 nM negative control siRNA or 30 nM ACKR3 siRNA for 48 h. In addition, negative control siRNA-transfected cells were also treated with ERK inhibitor (2 µM) and Akt inhibitor (10 µ...
Upregulation of TGF-尾1 was observed in ACKR3 overexpression, and TGF-尾1/Smad signaling activation and Akt phosphorylation were induced in HNSCC cells with ACKR3 overexpression. Treatment with a PI3K inhibitor reduced Slug and Twist levels while suppression of Smad2/3 signaling by siRNA reduced ...
This study investigated the effect of the strong CYP3A4 inhibitor, itraconazole, on the pharmacokinetics of single‐dose ACT‐1004‐1239 in healthy male subjects. In the open‐label, fixed‐sequence DDI study, a total of 16 subjects were treated. Each subject received a single ...
For experiments using specific chemical inhibitors, we added desired concentrations of an inhibitor to the cells before this one-hour time. We next added a small volume of luciferin to each well, waited 10 min before steady-state luminescence was reached, and then acquired a time 0 image prior...
