Methylpiperidinopyrazole

Methylpiperidinopyrazole (MPP) is a synthetic, nonsteroidal, and highly selective antagonist of ERα that is used in scientific research to study the function of this receptor.^[1][2] It has 200-fold selectivity for ERα over ERβ and 1000-fold selectivity for blocking ERα-mediated gene transcription relative to that of ERβ.^[3]
