Tametraline (CP-24,441) is the parent of a series of chemical compounds investigated at Pfizer that eventually led to the development of sertraline.

Sertraline has been called "3,4-dichloro-tametraline". This is correct but it is an oversimplification in the sense that sertraline is the S,S-isomer whereas tametraline is the 1R,4S-stereoisomer.^{[citation needed]}

1R-Methylamino-4S-phenyl-tetralin is a potent inhibitor of norepinephrine uptake in rat brain synaptosomes, reverses reserpine induced hypothermia in mice, and blocks uptake of ³H-Norepinephrine into rat heart.

Tametraline is a norepinephrine–dopamine reuptake inhibitor.

Indatraline is an indanamine homolog of tetralin-based tametraline, although in the case of indatraline the product is pm-dichlorinated.^{[citation needed]}
