Tametraline (CP-24,441) is the parent of a series of chemical compounds investigated at Pfizer that eventually led to the development of sertraline (CP-51,974-1).

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.

1R-Methylamino-4S-phenyl-tetralin is a potent inhibitor of norepinephrine uptake in rat brain synaptosomes,[2] reverses reserpine induced hypothermia in mice, and blocks uptake of 3H-Norepinephrine into rat heart.

[3] Tametraline is a norepinephrine-dopamine reuptake inhibitor.

[4] Indatraline is an indanamine homolog of tetralin-based tametraline, although in the case of indatraline the product is pm-dichlorinated.
