Fatal malignant hyperthermia occurred in a patient who was taking tranylcypromine (Parnate) and ingested wine and cheese. The case findings are presented along with a review of the literature concerning adverse interactions between monoamine oxidase (MAO) inhibitors and certain foods and beverages. Hyperthermia and its possible causative mechanisms and treatments are discussed. The facts suggest that the complicated dietary restrictions attending the use of MAO inhibitors and the possibility of severe and even catastrophic reactions resulting from violations of these restrictions make the use of these drugs fraught with danger and therefore not a first choice for the treatment of depression.

A broad spectrum monoamine oxidase inhibitor, tranylcypromine sulfate (Parnate) was tested in a new hamster separation model of depression. In this paradigm, male dwarf hamsters show increases in body weight, decreases in exploratory behaviors, and decreases in social interactions, when separated from female mates. Tranylcypromine (10 mg/kg s.c. daily for 14 days) effectively reduced body weight, increased exploration, and increased social interaction, in the separated males. Subsequent treatment with saline restored the separation-induced changes in body weight, exploratory behaviors, and other social behaviors. The 'separation syndrome' in dwarf hamsters appears to be completely reversed by at least one antidepressant treatment.

Demethylation of histone H3 lysine 4 is carried out by BHC110/LSD1, an enzyme with close homology to monoamine oxidases (MAO). Monoamine oxidase A or B are frequent targets of selective and nonselective small molecular inhibitors used for treatment of depression. Here we show that in contrast to selective monoamine oxidase inhibitors such as pargyline, nonselective monoamine oxidase inhibitors potently inhibit nucleosomal demethylation of histone H3 lysine 4. Tranylcypromine (brand name Parnate) displayed the best inhibitory activity with an IC50 of less than 2 microM. Treatment of P19 embryonal carcinoma cells with tranylcypromine resulted in global increase in H3K4 methylation as well as transcriptional derepression of two BHC110 target genes, Egr1 and the pluripotent stem cell marker Oct4. These results attest to the effectiveness of tranylcypromine as a small molecular inhibitor of histone demethylation.
