Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

Meccanismo d'azione (Mechanism of Action)

Caratteristiche	First orally administered PI3K inhibitor used in vivo.
Targets/IC₅₀/Ki	PI3Kδ (Cell-free assay) 4.6 nM PI3Kα (Cell-free assay) 16 nM PI3K (Cell-free assay) 37 nM PI3Kβ (Cell-free assay) 44 nM PI3Kγ (Cell-free assay) 49 nM
In vitro	ZSTK474 at 1 μM potently reduces PI3K activity to 4.7% of the control level, whereas LY2194002 only reduces the activity to 44.6% of the control. This compound inhibits the activities of recombinant p110β, -γ, and -δ with IC50 of 17 nM, 53 nM, and 6 nM, respectively. It shows potent antiproliferative activity against a panel of 39 human cancer cell lines with mean GI50 of 0.32 μM, more effectively than that of LY294002 or wortmannin with mean GI50 of 7.4 μM or 10 μM, respectively. This chemical treatment at 1 μM blocks membrane ruffling and generation of PIP3 induced by platelet-derived growth factor in murine embryonic fibroblasts (MEFs). It at 10 μM induces apoptosis in OVCAR3 cells, and induces complete G1-phase arrest but not apoptosis in A549 cells. This compound treatment at 0.5 μM significantly decreases the level of phosphorylated Akt and GSK-3β, as well as the cyclin D1 protein expression. It also inhibits the phosphorylation of other downstream signaling components that are involved in regulating cell proliferation including FKHRL1, FKHR, TSC-2, mTOR, and p70S6K in a dose-dependent manner. This chemical does not inhibit mTOR at 0.1 μM, and even at a concentration of 100 μM, it inhibits mTOR activity less than 40%. It blocks VEGF-induced cell migration and the tube formation in human umbilical vein endothelial cells (HUVECs), and inhibits the expression of HIF-1α and secretion of VEGF in RXF-631L cells, exhibiting potent in vitro antiangiogenic activity. This compound treatment inhibits the production of IFNγ and IL-17 in concanavalin A-activated T cells, and inhibits the proliferation and PGE(2) production by fibroblast-like synovial cells (FLS).
Saggio chinasico	Inibizione dell'attività di PI3K
Saggio chinasico	Le cellule A549 vengono lisate in un tampone contenente 20 mM Tris-HCl (pH 7,5), 150 mM NaCl, 5 mM EDTA e 1% Igepal CA-630, i lisati vengono centrifugati a 20.000 g e 4 °C per 10 minuti e i surnatanti vengono utilizzati come lisato cellulare (proteina = 2-4 mg/mL). Per immunoprecipitare la PI3K, 200 μL di lisato cellulare vengono incubati con anticorpo policlonale anti-p85 e proteina G-agarosio (5 μL). Le PI3Kα, PI3Kβ e PI3Kδ possono essere immunoprecipitate dall'anticorpo policlonale anti-p85. Le sfere di agarosio contenenti gli immunoprecipitati vengono lavate due volte con il tampone A (20 mM Tris-HCl a pH 7,5, 150 mM NaCl, 5 mM EDTA e 1% Igepal CA-630), una volta con il tampone B (500 mM LiCl e 100 mM Tris-HCl a pH 7,5), una volta con acqua distillata e una volta con il tampone C (100 mM NaCl e 20 mM Tris-HCl a pH 7,5). Gli immunoprecipitati vengono sospesi in 20 μL di tampone C contenente fosfatidilinositolo a 200 μg/mL. La miscela viene preincubata con concentrazioni crescenti di questo composto a 25 °C per 5 minuti. Vengono aggiunti [γ-³²P]ATP (2 μCi per miscela di saggio; concentrazione finale, 20 μM) e MgCl₂ (concentrazione finale, 20 mM) per avviare la reazione. La miscela di reazione viene incubata a 25 °C per 20 minuti. I prodotti fosforilati del fosfatidilinositolo vengono separati mediante cromatografia su strato sottile e visualizzati mediante autoradiografia. La regione del fosfatidilinositolo-3-fosfato viene raschiata dalla piastra e la radioattività viene misurata anche con spettroscopia a scintillazione liquida. Il livello di inibizione di questa sostanza chimica viene determinato come la percentuale di conteggi di ³²P per minuto ottenuti senza questo composto.
In vivo	Oral administration of ZSTK474 inhibits the growth of subcutaneously implanted mouse B16F10 melanoma tumors in a dose-dependent manner, producing tumor regression of 28.5%, 7.1%, or 4.9% on day 14 at 100, 200, or 400 mg/kg, respectively, which is superior to that of the four major anticancer drugs at their respective maximum tolerable doses with tumor regression of 96%, 35.7%, 24%, or 68.3%, respectively. This compound treatment at 400 mg/kg completely inhibits the growth of A549, PC-3, and WiDr xenografts in mice, and induces the regression of A549 xenograft tumors. It significantly inhibits tumor growth in the RXF-631L xenograft model, correlated with a significantly reduced number of microvessels in the treated mice. Oral administration of this chemical ameliorates the progression of adjuvant-induced arthritis (AIA) in rats.
