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