Meccanismo d'azione (Mechanism of Action)

Targets/IC₅₀/Ki	HER2 (Cell-free assay) 59 nM EGFR (Cell-free assay) 92 nM KDR (Cell-free assay) 800 nM Src (Cell-free assay) 1.4 μM
In vitro	Neratinib weakly inhibits tyrosine kinases KDR and Src with IC50 of 0.8 μM and 1.4 μM, respectively, being 14- and 24-fold less active compared with HER2. This compound displays no activity against other serine-threonine kinases such as Akt, cyclin D1/cdk4, cyclin E/cdk2, cyclin B1/cdk1, IKK-2, MK-2, PDK1, c-Raf, and Tpl-2, as well as the tyrosine kinase c-Met. It selectively inhibits the proliferation of 3T3 cells transfected with the HER2 (3T3/neu), as well as two other HER-2-overexpressing SK-Br-3 and BT474 cells with IC50 values of 2-3 nM, displaying >230-fold potency compared with non-transfected 3T3 cells as well as MDA-MB-435 and SW620 which are EGFR- and HER2-negative. This chemical also inhibits the proliferation of EGFR-dependent A431 cells with an IC50 of 81 nM. It reduces HER2 receptor autophosphorylation in BT474 cells with an IC50 of 5 nM, and EGF-dependent phosphorylation of EGFR in A431 cells with IC50 of 3 nM. Blocking of HER-2 by this compound results in inhibition of downstream MAPK and Akt pathways with IC50 of 2 nM, more potently than Trastuzumab. It inhibits the cyclin D1 expression and the phosphorylation of the Rb-susceptibility gene production in BT474 cells with IC50 of 9 nM, leading to G1-S arrest and ultimately decreased cell proliferation.
Saggio chinasico	Saggio di autofosforilazione senza cellule utilizzando fluorometria risolta nel tempo
Saggio chinasico	Neratinib viene preparato come scorte da 10 mg/mL in DMSO e diluito in 25 mM HEPES (pH 7,5; 0,002 ng/mL-20 μg/mL). Frammenti ricombinanti purificati C-terminali di HER2 (amminoacidi 676-1255) o del recettore del fattore di crescita epidermico (EGFR) (amminoacidi 645-1186) [diluiti in 100 mM HEPES (pH 7,5) e 50% glicerolo] vengono incubati con concentrazioni crescenti di questo composto in 4 mM HEPES (pH 7,5), 0,4 mM MnCl₂, 20 μM vanadato di sodio e 0,2 mM DTT per 15 minuti a temperatura ambiente in piastre ELISA a 96 pozzetti. La reazione chinasica viene avviata dall'aggiunta di 40 μM ATP e 20 mM MgCl₂ e lasciata procedere per 1 ora a temperatura ambiente. Le piastre vengono lavate e la fosforilazione viene rilevata utilizzando anticorpi anti-fosfo-tirosina marcati con Europio (15 ng/pozzetto). Dopo i passaggi di lavaggio e di potenziamento, il segnale viene rilevato utilizzando un lettore di fluorescenza Victor2 (lunghezza d'onda di eccitazione 340 nm, lunghezza d'onda di emissione 615 nm). La concentrazione di questa sostanza chimica che inibisce la fosforilazione del recettore del 50% (IC50) viene calcolata dalle curve di inibizione.
In vivo	Oral administration of Neratinib significantly inhibits the growth of 3T3/neu xenografts, with inhibition of 34%, 53%, 98%, and 98% at dose of 10, 20, 40, and 80 mg/kg/day, respectively. Consistent with the inhibition of HER-2 phosphorylation by 84% within 1 hour of administration at 40 mg/kg/day, this compound inhibits the growth of BT474 xenografts by 70-82%, 67%, and 93% at dose of 5, 10, and 40 mg/kg/day, respectively. It is also effective against SK-OV-3 xenografts with inhibition of 31% and 85% at 5 and 60 mg/kg/day, respectively. This chemical is less potent against EGFR-dependent A431 xenografts than HER-2-dependent tumors, with 32% and 44% inhibition at 5 and 20 mg/kg/day, respectively. It displays little activity against MCF-7 and MX-1 xenografts expressing low levels of HER-2 and EGFR, with only 28% inhibition at 80 mg/kg/day, suggesting that it has selective activity for cells expressing HER-2 or EGFR.
