| 生物活性 | PD 168368 is a potent, competitive, and selectiveneuromedin B receptor(NMB-R) antagonist with theKiof 15–45 nM[1]. PD 168368 is neuromedin B receptor (NMBR;IC50=96 nM) / gastrin-releasing peptide receptor (GRPRIC50=3500 nM) antagonist[2]. PD 168368 also is a mixedFPR1/FPR2/FPR3agonist withEC50s of 0.57, 0.24, and 2.7 nM, respectively[3]. |
体外研究
(In Vitro) | PD 168368 (PD168368) is highly active and stimulated [Ca2+]Irelease in human neutrophils with EC50values in the nanomolar range[3].
PD 168368 (PD168368) suppresses migration and invasion of the human breast cancer cell line MDA-MB-231. PD 168368 reduces epithelial-mesenchymal transition (EMT) of breast cancer cells by E-cadherin upregulation and vimentin downregulation. PD 168368 (5 μM) inhibits migration and invasiveness in breast cancer cells[4].
PD 168368 (10 μM) suppresses the activation of mTOR/p70S6K/4EBP1 and AKT/GSK-3β pathways in breast cancer cells[4].
Cell Viability Assay[4] | Cell Line: | Human breast cancer cell line MDA-MB-231 | | Concentration: | 5 μM | | Incubation Time: | 24 hours | | Result: | Clearly decreased the migratory ability of MDA-MB-231 cells in a Boyden chamber migration assay. |
Cell Viability Assay[4] | Cell Line: | MDA-MB-231 cells | | Concentration: | 10 μM | | Incubation Time: | 0, 0.5, 1, 2, 4, 8, and 16 hours | | Result: | Decreased phosphorylation levels of mTOR, p70S6K, 4EBP1, AKT and GSK-3β in a time-dependent manner. |

体内研究
(In Vivo) | PD 168368 (PD168368) potently inhibits in vivo metastasis of breast cancer. PD 168368 (1.2 mg/kg; intraperitoneal injection for 30 days) inhibits metastasis of breast cancer in mice[4].
| Animal Model: | Female BALB/c-nude mice (age 8-10 weeks) bearing MDA-MB-231 xenograft model[4] | | Dosage: | 1.2 mg/kg | | Administration: | Intraperitoneal injection for 30 days | | Result: | No metastatic tumor nodules were observed in lungs of PD 168368-treated mice compared to PEG-injected mice. |
