In Vitro LY288513 (10 nM; 2 days) suppresses the effects of CCK-8 on CD4+ T cell subset-specific transcription factors[2]. RT-PCR[2] Cell Line: CD4+ T cells Concentration: 10 nM Incubation Time: 2 days Result: Suppressed the effects of CCK-8 on CD4+ T cell subset-specific transcription factors.
In Vivo LY288513 (3, 10 mg/kg, i.p.; 10, 30 mg/kg, p.o.) produces an anxiolytic-like action[3]. LY288513 (1000 mg/kg, p.o.) potentiates the effects of a CNS depressant, slightly lowered body temperature, and had modest sedative effects only at the highest dose examined[3]. Animal Model: Male CD-l mice[3] Dosage: 3, 10 mg/kg; 10, 30 mg/kg Administration: I.p.; p.o. Result: Displayed anxiolytic-like effects in the elevated plusmaze.
