Actividad biológica
| Descripción | Pelitinib (EKB-569) es un potente inhibidor irreversible de EGFR con una IC50 de 38,5 nM. Este compuesto también inhibe ligeramente Src, MEK/ERK y ErbB2 con IC50s de 282 nM, 800 nM y 1255 nM, respectivamente. Fase 2. | ||||||||||

| In vitro | Pelitinib (EKB-569) displays much higher inhibitory activity against EGFR, compared with the closely related c-erbB-2, as well as other kinases such as Src, Cdk4, c-Met, Raf, and MEK/ERK, with IC50 ranging from 282 nM for Src to >20 μM for Cdk4. Consistently, this compound treatment significantly inhibits the autophosphorylation of EGFR but not c-Met in A431 cells. It potently inhibits the proliferation of normal human keratinocytes (NHEK), as well as A431 and MDA-468 tumor cells with IC50 of 61 nM, 125 nM, and 260 nM, respectively, while displaying little activity against MCF-7 cells with IC50 of 3.6 μM. This chemical inhibits EGF-induced phosphorylation of EGFR in A431 and NHEK cells with IC50 of 20-80 nM, as well as the phosphorylation of STAT3 with IC50 of 30-70 nM. It at 75-500 nM also specifically inhibits the activation of AKT and ERK1/2, without affecting NF-κB pathway. In NHEK cells, this compound also potently inhibits TGF-α mediated EGFR activation with IC50 of 56 nM, as well as activation of STAT3 and ERK1/2 with IC50 of 60 nM and 62 nM, respectively. | ||||||||||
| In vivo | A single oral dose of 10 mg/kg Pelitinib (EKB-569) potently inhibits the EGFR phosphorylation in A431 xenografts with over-expressed EGFR, by 90% within 1 hour, and by >50% after 24 hours. Administration of this compound at 20 mg/kg/day inhibits tumorigenesis in APCMin/+ mice by 87%, equivalent to the effect of used with 2 times doses of EKI-785 (40 mg/kg/day), consistent with greater in vivo potency. This chemical selectively inhibits EGFR signaling in airway epithelial cells in vivo. In the mouse model of airway epithelial remodeling that is inducible by viral infection and features a delayed but permanent switch to goblet cell metaplasia, this compound treatment at 20 mg/kg/day corrects all 3 aspects of epithelial remodeling, by completely blocking the increase of ciliated cells and decrease of Clara cells, and significantly inhibiting the metaplasia of goblet cells. | ||||||||||
