작용 메커니즘 (Mechanism of Action)

특징	Clinically used oral formulation of R406.
Targets/IC₅₀/Ki	Syk (Cell-free assay) 41 nM
시험관 내(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.
키나아제 분석	In vitro 형광 편광 키나아제 분석
키나아제 분석	R406(R935788의 시험관 내 활성 형태)를 DMSO로 연속 희석한 후, 키나아제 완충액(20 mM HEPES, pH 7.4, 5 mM MgCl₂, 2 mM MnCl₂, 1 mM DTT, 0.1 mg/mL 아세틸화 BGG)에서 1% DMSO가 되도록 희석합니다. 키나아제 완충액 내의 ATP와 기질을 실온에서 첨가하여 최종 DMSO 농도를 0.2%로 맞춥니다. 키나아제 반응은 5 μM HS1 펩타이드 기질과 4 μM ATP를 포함하는 20 μL의 최종 부피에서 수행되며, 키나아제 완충액에 담긴 0.125 ng의 Syk를 첨가하여 시작합니다. 반응은 실온에서 40분 동안 진행됩니다. 반응은 FP 희석 완충액에 희석된 EDTA/항-포스포티로신 항체(최종 1×)/형광 포스포펩타이드 추적자(최종 0.5×)를 포함하는 20 μL의 PTK 퀜치 믹스를 첨가하여 중단합니다. 플레이트를 암소에서 실온 상태로 30분 동안 배양한 후, Polarion 형광 편광 플레이트 판독기로 판독합니다. 데이터는 Tyrosine Kinase Assay Kit에서 제공된 포스포펩타이드 경쟁자와의 경쟁을 통해 생성된 검량선을 사용하여 존재하는 포스포펩타이드의 양을 결정하도록 변환됩니다. IC50 결정을 위해, R406을 11가지 농도에서 이중으로 테스트하며 Prism GraphPad 소프트웨어를 사용한 비선형 회귀 분석으로 곡선 피팅을 수행합니다.
생체 내(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.

자주 묻는 질문 (Frequently Asked Questions)

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

답변:
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.
