Verkningsmekanism (Mechanism of Action)

Egenskaper	Clinically used oral formulation of R406.
Targets/IC₅₀/Ki	Syk (Cell-free assay) 41 nM
In vitro	R935788 is a methylene phosphate prodrug of R406, which can be rapidly converted to R406 in vivo. R406 (in vitro active form of R935788) selectively inhibits Syk-dependent signaling with EC50 values ranging from 33 nM to 171 nM, more potently than Syk-independent pathways in different cells. R406 inhibits cellular proliferation of a variety of diffuse large B-cell lymphoma (DLBCL) cell lines with EC50 values ranging from 0.8 μM to 8.1 μM. R406 treatment reduces basal phosphorylation of BLNK, Akt, glycogen synthase kinase-3 (GSK-3), forkhead box O (FOXO) and ERK not only in cells with high (TCL-002) but also in cells with low levels of phosphorylated Syk (TCL1-551). In addition, R406 completely inhibits the anti-IgM induced Bcr signal in TCL1 leukemias. Despite the higher levels of constitutively active Syk in TCL1 leukemias, R406 is not selectively cytotoxic to the leukemic cells.
Kinasanalys	In vitro fluorescenspolarisationskinasanalyser
Kinasanalys	R406 (in vitro aktiv form av R935788) späds i serier i DMSO och späds sedan till 1% DMSO i kinasbuffert (20 mM HEPES, pH 7,4, 5 mM MgCl₂, 2 mM MnCl₂, 1 mM DTT, 0,1 mg/mL acetylerad BGG). ATP och substrat i kinasbuffert tillsätts vid rumstemperatur, vilket resulterar i en slutlig DMSO-koncentration på 0,2%. Kinasreaktionerna utförs i en slutvolym på 20 μL innehållande 5 μM HS1-peptidsubstrat och 4 μM ATP och startas genom tillsats av 0,125 ng Syk i kinasbuffert. Reaktionen får fortsätta i 40 minuter vid rumstemperatur. Reaktionen stoppas genom tillsats av 20 μL PTK-släckningsmix innehållande EDTA/anti-fosfotyrosinantikropp (1× slutlig)/fluorescerande fosfopeptidspårare (0,5× slutlig) utspädd i FP-spädningsbuffert. Plattan inkuberas i 30 minuter i mörker vid rumstemperatur och läses sedan av på en Polarion fluorescenspolarisationsplattläsare. Data konverteras för att bestämma mängden fosfopeptid som finns med hjälp av en kalibreringskurva genererad genom konkurrens med fosfopeptidkonkurrenten som tillhandahålls i Tyrosine Kinase Assay Kit. För IC50-bestämning testas R406 vid elva koncentrationer i dubblett och kurvanpassning utförs genom icke-linjär regressionsanalys med Prism GraphPad Software.
In vivo	Given that plasma half-life of R406 in mice is less than 2 hours, R935788 is administered in 3 divided doses at 3-hour intervals to provide continuous Syk inhibition during each day of treatment, mimicking the longer plasma half-life in humans (15 hours). Despite the relatively modest cytotoxic effect in vitro, R935788 significantly inhibits the proliferation and survival of leukemic cell in vivo, which is associated with the blocking of antigen-dependent B-cell receptor (Bcr) signaling rather than inhibition of constitutive Syk activity. R935788 treatment at 80 mg/kg/day for 18-21 days potently inhibits tumor growth of TCL1-002, TCL1-551 and TCL1-870 in mice with undetectable leukemic CD5⁺/B220⁺ cells at the last day of treatment, significantly prolongs the survival of the treated mice with median survival increased from 45/46 days to 170/172 days, and completely eradicates the malignant cells in a substantial proportion of mice after a 6-month follow-up period without affecting the production of normal B lymphocytes. R935788 treatment also induces an early and transient migration of both normal and malignant B cells from spleen and lymph nodes to peripheral blood, which is subsequently followed by selective growth inhibition of the malignant B-cell population. In addition, R935788 is also effective against spontaneously developing TCL1 leukemias in Eμ-TCL1 transgenic mice.

Vanliga frågor (Frequently Asked Questions)

Fråga 1:
What’s the difference between S2625 and S2206?

Svar:
The differences between S2625 and S2206: 1. S2206 is more stable than S2625; 2. The water solubility of S2206 is better than S2625; 3. The absorption of S2206 is harder than S2625, so you need to test the suitable dosage if you use it in animal assays; 4. The potency of S2206 and S2625 is similar.
