TC14012, a serum-stable derivative of T140, is a selective and peptidomimetic CXCR4 antagonist with an IC50 of 19.3 nM. TC14012 is a potent CXCR7 agonist with an EC50 of 350 nM for recruiting β-arrestin 2 to CXCR7. TC14012 has anti-HIV activity and anti-cancer activity [1-3].
TC14012(10-10-10-5M ; 37℃; 90 min) induce coupling of CXCR7 with β-arrestin in a dose-dependent manner in 293FT cell β-Arrestin recruitment assay[4]. In TC14012-treated(0-30µM) HUVECs(human umbilical vein endothelial cells), specific activation of CXCR7 significantly promoted the tubular formation of HUVECs[5]. TC14012 may promote osteogenesis or chondrodifferentiation in the treatment of mesenchymal stem cell (MSC) [6].
TC14012(10 mg/kg; i.p. ; 4 times every 6 days) significantly increased the left ventricular internal diameter-diastole/systole (LVID-d/s), a key cardiac structure index, and the EFFS, and left ventricular volume-diastole/systole (LV vol-d/s) in AMI mice. TC14012 reduced the infarct size and increased the vascular density in AMI model mice. TC14012 promoted angiogenesis in vivo, and TC14012 increased the levels of VWF, VEGFR2, p-SRC and p-PLC-γ as well as the p-P38/t-P38 ratio [7].
