Tranylcypromine hemisulfate (dl-Tranylcypromine hemisulfate)

Animal experiment:

Briefly, the rats are anesthetized with an intraperitoneal injection of a 1:1 mixture of xylazine hydrochloride (4 mg/kg) and ketamine hydrochloride (10 mg/kg). Then, the pupil is dilated with phenylephrine hydrochloride and tropicamide eye drops, and 20 nmol NMDA with or without tranylcypromine is injected into the vitreous cavity. To assess the inhibitory effect of mitogen-activated protein kinase (MAPK), 100 nmol BIRB796 is intravitreally injected at the same time of NMDA injection. The injections are performed under a microscope using a 33-gauge needle connected to a microsyringe; the needle is inserted approximately 1.0 mm behind the corneal limbus. Next, either PBS (vehicle control) or 500 mM tranylcypromine (1000 nmol) mixed with 10 mM NMDA (20 nmol) in a total volume of 2.0 μL is injected into the vitreous cavity.
