“…The MAO inhibitors which have hydrazine and amine moiety such as isocarboxazid (Shader and Greenblatt, 1999), phenelzine (Urichuk, et al, 2000), and moclobemide (Ferigolo et al, 1998) show prominent antidepressant activity in animals and man. The antidepressant activity of 1-N-substituted thiocarbamoyl-3-phenyl-5-thienyl-2-pyrazolines was found to be similar to those of MAO inhibitors (Gökhan et al, 2003). Additionally, it has been shown that 1,3,5-triphenyl-2-pyrazolines (Prasad et al, 2005), 1-thiocarbamoyl-3,5-diphenyl-2-pyrazolines (Bilgin et al, 1993), bicyclic pyrazoline 8-thiocarbamoyl-7,8-diazabicyclo[4.3.0]non-6-ene derivatives (Palaska et al, 1996), and 3,5-difenil-2-pirazolines (Palaska et al, 2001) have antidepressant activity in forced swimming test.…”
