CYM5442 is a potent, highly-selective and orally active sphingosine 1-phosphate (S1P1) receptor agonist with an EC50 of 1.35 nM. CYM5442 is inactive against S1P2, S1P3, S1P4, and S1P5. CYM5442 activates S1P1-dependent p42/p44-MAPK phosphorylation. CYM5442 exerts retinal neuroprotection. CYM5442 can easily penetrate the central nervous system (CNS).

Description

CYM5442 is a potent, highly-selective and orally active sphingosine 1-phosphate (S1P1) receptor agonist with an EC50 of 1.35 nM. CYM5442 is inactive against S1P2, S1P3, S1P4, and S1P5. CYM5442 activates S1P1-dependent p42/p44-MAPK phosphorylation. CYM5442 exerts retinal neuroprotection. CYM5442 can easily penetrate the central nervous system (CNS)[1][2].

IC50 & Target

EC50: 1.35 nM (Sphingosine 1-phosphate (S1P1) receptor)[1]

In Vitro

CYM5442 (0.5 µM; 0-60 minutes; HEK293 cells) treatment stimulates S1P1 phosphorylation in a time-dependent manner in P32-orthophosphate labeled cells[1].
CYM5442 activates S1P1-dependent p42/p44-MAPK phosphorylation in CHO-K1 cells transfected with S1P1 with an EC50 of 46 nM. The R120 for alanine (R120A) mutant is still able to maintain p42/p44-MAPK activity when incubated with CYM5442 (EC50 of 67 nM). Activation of p42/p44-MAPK by CYM5442 in E121A S1P1 cells is concentration dependent, with a mean EC50 value of 134 nM[1].

Western Blot Analysis[1]

Cell Line: HEK293 cells stably expressing S1P1 fused to GFP on the carboxy-terminus
Concentration: 0.5 µM
Incubation Time: 0 minutes, 2 minutes, 5 minutes, 10 minutes, 30 minutes, 60 minutes
Result: Stimulated S1P1 phosphorylation in a time-dependent manner.
In Vivo

CYM5442 (1 mg/kg; intraperitoneal injection; daily; for 5 days; adult male albino Wistar rats) treatment shows preserved visual function of visual evoked potentials (VEP). Retinal nerve fiber layer (RNFL) is significantly thicker in the CYM treated-animals compared to the vehicle[2].

Animal Model: Adult male albino Wistar rats (8-10 weeks old; 180-230 g) infected ocular endothelin-1 (ET-1)[2]
Dosage: 1 mg/kg
Administration: Intraperitoneal injection; daily; for 5 days
Result: Visual evoked potentials (VEP) showed preserved visual function. Showed significantly higher retinal ganglion cells (RGCs) numbers.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
