Meccanismo d'azione (Mechanism of Action)

Caratteristiche	Lead drug candidate for rheumatoid arthritis.
Targets/IC₅₀/Ki	Flt3 (Cell-free assay) Syk (Cell-free assay) 41 nM
In vitro	R406 is a potent inhibitor of immunoglobulin E (IgE)- and IgG-mediated activation of Fc receptor signaling. This compound inhibits the anti-IgE-induced production and release of LTC4 and cytokines and chemokines, including TNFα, IL-8, and GM-CSF. It inhibits phosphorylation of Syk substrate linker for activation of T cells in mast cells and B-cell linker protein/SLP65 in B cells. This chemical binds to the ATP binding pocket of Syk and inhibits its kinase activity as an ATP-competitive inhibitor with K_i of 30 nM. It blocks Syk-dependent FcR-mediated activation of monocytes/macrophages and neutrophils and Bcr-mediated activation of B lymphocytes. This compound significantly induces chronic lymphocytic leukemia (CLL) cell apoptosis in nurselike cells cocultures and blocks CCL3 and CCL4 secretion by CLL cells in response to B-cell antigen receptor (Bcr) triggering. It is a potent inhibitor of platelet signaling and functions initiated by FcγRIIA cross-linking by specific antibodies or by sera from HIT patients.
Saggio chinasico	Saggio chinasico di polarizzazione di fluorescenza in vitro
Saggio chinasico	R406 viene diluito in serie in DMSO e quindi diluito all'1% di DMSO in tampone chinasico (20 mM HEPES, pH 7,4, 5 mM MgCl₂, 2 mM MnCl₂, 1 mM DTT, 0,1 mg/mL BGG acetilato). ATP e substrato in tampone chinasico vengono aggiunti a temperatura ambiente, risultando in una concentrazione finale di DMSO dello 0,2%. Le reazioni chinasiche vengono eseguite in un volume finale di 20 µL contenente 5 mM di substrato peptidico HS1, 4 mM di ATP e avviate con l'aggiunta di 0,125 ng di Syk in tampone chinasico. La reazione è lasciata procedere per 40 minuti a temperatura ambiente. La reazione viene interrotta con l'aggiunta di 20 µL di miscela di quenching PTK contenente EDTA/anticorpo anti-fosfotirosina (1X finale)/tracciante fosfopeptidico fluorescente (0,5X finale) diluita in tampone di diluizione FP. La piastra viene incubata per 30 minuti al buio a temperatura ambiente e quindi letta su un lettore di piastre a polarizzazione di fluorescenza Polarion. I dati vengono convertiti in quantità di fosfopeptide presente utilizzando una curva di calibrazione generata per competizione con il competitore fosfopeptidico fornito nel kit di saggio tirosina chinasi. Per la determinazione dell'IC50, questo composto viene testato a undici concentrazioni e l'adattamento della curva viene eseguito mediante analisi di regressione non lineare.
In vivo	R406 reduces cutaneous reverse passive Arthus reaction by approximately 86% at 5 mg/kg in prophylactic treated mice. This compound also shows efficacy in inhibiting paw inflammation in antibody-induced arthritis mouse models. It does not adversely affect macrophage or neutrophil function in innate immune responses and has minimal functional immunotoxicity notwithstanding its lymphocytopenic effect.

Domande Frequenti (Frequently Asked Questions)

Domanda 1:
What’s the difference between S1533 and S2194?

Risposta:
S1533 and S2194 are two different forms of this compound. S1533 is the free base form, containing only its molecule without an acid added to it. S2194 has an additional C6H6O3S acid on it which makes the molecule a salt form. The free base and salt forms have same biology activities. Free base has a lower molecular weight and salt form has a better solubility in DMSO.
