PPPA, or 3-phenoxy-3-phenylpropan-1-amine, is a drug which is described as an antidepressant.[1] It was derived by Eli Lilly from the antihistamine diphenhydramine, a 2-diphenylmethoxyethanamine derivative with additional properties as a selective serotonin reuptake inhibitor (SSRI), and has been the basis for the subsequent discovery of a number of other antidepressant drugs.[2][3][4]

List of PPPA derivatives

  • Atomoxetine ((3R)-N-methyl-3-(2-methylphenoxy)-3-phenylpropan-1-amine) - NRI[1]
  • Fluoxetine (N-methyl-3-(4-(trifluoromethyl)phenoxy)-3-phenylpropan-1-amine) - SSRI[2]
  • N-Methyl-PPPA (N-methyl-3-phenoxy-3-phenylpropan-1-amine) - SNRI[2][4]
  • Nisoxetine (N-methyl-3-(2-methoxyphenoxy)-3-phenylpropan-1-amine) - NRI[1]
  • Norfluoxetine (3-(4-(trifluoromethyl)phenoxy)-3-phenylpropan-1-amine) - SSRI[3]
  • Seproxetine ((S)-3-(4-(trifluoromethyl)phenoxy)-3-phenylpropan-1-amine) - SSRI[5]

Structurally related drugs include dapoxetine, duloxetine, edivoxetine, femoxetine, paroxetine, reboxetine, and viloxazine, all of which act, similarly, as monoamine reuptake inhibitors, and most of which are, again similarly, antidepressants.[1][3]

Zimelidine is an antidepressant and SSRI which was derived from the antihistamine pheniramine, which, similarly to its analogues brompheniramine and chlorpheniramine, possesses SNRI properties.[4] Fluvoxamine, another antidepressant and SSRI, was developed from the antihistamine tripelennamine, which possesses SNDRI actions.[6]
