Biological Activity

Chlorotrianisene is a non-steroidal synthetic estrogen that was formerly used for the treatment of menopause, deficiencies in ovary function, and prostate cancer. Chlorotrianisene may react vigorously with strong oxidizing agents. Can react exothermically with reducing agents (such as alkali metals and hydrides) to release gaseous hydrogen. Chlorotrianisene exhibits in vitro little or no binding to the uterine estrogen receptor (ER) but demonstrates potent estrogenic activity in vivo, indicating that Chlorotrianisene is a proestrogen/proantiestrogen. Chlorotrianisene could inhibit bone loss and delay the atrophy of uterus induced by ovariectomy in Wistar female rats. It has protective effects on bone like other estrogen preparations.

Conversion of different model animals based on BSA (Value based on data from FDA Draft Guidelines)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
