8-Diethylamino-octyl-3,4,5-trimethoxybenzoate, a calcium store blocker, increases calcium influx, inhibits alpha-1 adrenergic receptor calcium mobilization, and alters iodide transport in FRTL-5 rat thyroid cells.

8-Diethylamino-octyl-3,4,5-trimethoxybenzoate (TMB-8) is known to inhibit mobilization of calcium from intracellular stores but, more recently, other cellular effects have been described. In the present study, the effects of TMB-8 on cytosolic free calcium [Ca2+]i levels in FRTL-5 rat thyroid cells were determined using the fluorescent dye, Indo-1. TMB-8… CONTINUE READING
