UC-1728 is a potent rabbit soluble epoxide hydrolase (sEH) inhibitor, with an IC50 of 2 nM on rabbit liver.

IC50 & Target

IC50: 2 nM (rabbit sHE)[1].

In Vivo

Miotic, fixed pupils are observed in the treated eyes of both groups receiving LPS injections but the difference in pupillary light reflex scores is only significantly increased in the UC-1728/LPS treated group relative to the PBS group at 6 h post-injection[1]. Pretreatment with UC-1728 (t-TUCB) at 10 and 30 mg/kg, p.o., significantly prevents ISO induced increase in heart weight and elevation of CK-MB and LDH levels (p<0.05), indicating its cardioprotective effect against ISO induced cardiac injury. At 3 mg/kg, p.o. UC-1728 only shows significant protection against heart weight changes. Pretreatment with UC-1728 at 3, 10 and 30 mg/kg, p.o., significantly reduces the ISO induced infarct size (p<0.05) when compared to control. The calculated percentage reductions for these doses are found to by 15.90, 46.60 and 40.44%, respectively[2]. Inhibition of sEH with UC-1728 is associated with a significant improvement in pain scores in one horse with laminitis whose pain is refractory to the standard of care therapy. No adverse effects are noticed[3].

Animal Administration

Eighteen male SPF New Zealand White Rabbits (2.6-3.2 Kg) are randomly assigned to 3 groups of 6 rabbits each. Rabbits in group 1 have 20 μL sterile PBS intracamerally injected in the right eye (negative control) and all other rabbits receive 100 ng LPS in 20 μL of PBS. Groups 2 and 3 are treated with anti-inflammatory drug or vehicle once daily on the following schedule: 24 h prior to intra-cameral LPS or PBS injection, the day of injection and 24 h post-injection. Group 2 receive UC-1728 (3 mg/kg, SC) and Group 3 receive PEG400 vehicle only (0.9 mL, subcutaneously, (SC)). To limit post-procedural discomfort, systemic buprenorphine (0.03 mg/kg SC) is administered immediately prior to returning rabbits to their cages upon recovery from anesthesia, then every 6-12 h for the first 24 h and as needed for the duration of the study[1].
