Meso-Butestrol

meso-Butestrol (developmental code name SC-3402), also known as 2,3-bis(4-hydroxyphenyl)butane, is a synthetic nonsteroidal estrogen which was never marketed.^{[1][2][3][4][5][6][7]} It is a so-called "short-acting" or "impeded" estrogen.^{[1][2][3][5][4][6][7]} meso-Butestrol is structurally related to diethylstilbestrol and other stilbestrols.^[8] The fully potent counterpart to meso-butestrol is meso-hexestrol, analogously to the relationship of dimethylstilbestrol to diethylstilbestrol.^[3]
