Mecanismo de acción (Mechanism of Action)

Características	An allosteric, potent, specific, and reversible inhibitor of the mitotic kinesin spindle protein (KSP) (HsEg5).
Targets/IC₅₀/Ki	KSP (HsEg5) (Cell-free assay) 1.7 nM(Ki app)
In vitro	Ispinesib (SB-715992) is a potent, allosteric, reversible, and specific inhibitor of KSP, which changes the binding property of KSP to microtubules and disturbs its movement by inhibiting ADP release without altering the release of the KSP-ADP complex from the microtubule. This compound shows potent cytotoxic activity in a panel of tumor cell lines, including Colo205, Colo201, HT-29, M5076, Madison-109, and MX-1, with IC50 of 1.2 nM to 9.5 nM. In PC-3 prostate cancer cells, it (15 nM and 30 nM) blocks cell proliferation and induces apoptosis by regulating the expression levels of genes that controls apoptosis, cell proliferation, cell cycle, and cell signaling, such as EGFR, p27, p15, and IL-11. In a panel of 53 breast cell lines, Ispinesib (7.4 nM–600 nM) demonstrates broad inhibitory activity. In BT-474 and MDA-MB-468 cells, it (150 nM) induces apoptosis, as revealed by a higher proportion of apoptotic cells, lower antiapoptotic Bcl-X_L level, and higher proapoptotic Bax and Bid levels.
Ensayo de quinasa	Análisis Cinético en Estado Estacionario de la Actividad ATPasa de KSP Humana y su Inhibición por Ispinesib
Ensayo de quinasa	El análisis de la especificidad de la Kinesin se lleva a cabo utilizando un sistema de detección de piruvato quinasa-lactato deshidrogenasa que acopla la producción de ADP a la oxidación de NADH. Los cambios de absorbancia se monitorean a 340 nm. Los estudios en estado estacionario utilizando concentraciones nanomolares de KSP se realizan mediante un ensayo sensible basado en fluorescencia que utiliza un sistema de detección acoplado de piruvato quinasa, piruvato oxidasa y peroxidasa de rábano (HRP) que acopla la generación de ADP a la oxidación de Amplex Red a resorufina fluorescente. La generación de resorufina se monitorea por fluorescencia (λ_excitación = 520 nm y λ_emisión = 580 nm). Los experimentos bioquímicos en estado estacionario se realizan en tampón PEM25 [25 mM Pipes-K⁺ (pH 6,8), 2 mM MgCl₂, 1 mM EGTA] para experimentos que involucran microtúbulos. La IC50 para la inhibición en estado estacionario se determina a 500 µM ATP, 5 µM microtúbulos y 1 nM KSP en tampón PEM25. Los valores de K_{i app} (constante de disociación aparente del inhibidor) de Ispinesib (SB-715992) se extraen de las curvas de dosis-respuesta, con corrección explícita de la concentración de la enzima utilizando la ecuación de Morrison. La modalidad del inhibidor (por ejemplo, competitivo, no competitivo, acompetitivo o mixto) bajo condiciones de estado estacionario se determina midiendo el efecto de su concentración sobre la velocidad inicial en función de las concentraciones de sustrato. Los datos se ajustan utilizando ecuaciones en GraFit a ecuaciones de velocidad para los diversos modos de inhibición.
In vivo	Ispinesib (SB-715992) (4.5 mg/kg–15 mg/kg) exhibits inhibitory effects against Colo205, Colo201, HT-29, but not MX-1 cells, in mouse xenograft models. This compound (6 mg/kg–10 mg/kg) also inhibits murine solid tumors, including Madison 109 lung carcinoma, M5076 sarcoma, as well as L1210 and P388 leukemias. In mice xenograft models of breast cancer cells MCF-7, HCC1954, MDA-MB-468, and KPL4, it (8 mg/kg–10 mg/kg) inhibits tumor growth.
