ixazomib

Ixazomib (MLN2238) , a second generation, boron-containing peptide proteasome inhibitor (PI), inhibits the chymotrypsin-like proteolytic (β5) site of the 20S proteasome (IC50/Ki: 3.4/0.93 nM, in cell-free assays), also inhibits the caspase-like (β1) and trypsin-like (β2) proteolytic sites (IC50: 31/3500 nM).

Ixazomib citrate, also known as MLN9708, is a prodrug of Ixazomib (MMLN-2238). MLN9708 is an orally bioavailable second generation proteasome inhibitor (PI) with potential antineoplastic activity. MLN9708, after hydrolyzing to pharmacologically active MLN2238 (ixazomib), is a next-generation proteasome inhibitor with demonstrated preclinical and clinical antimyeloma activity. MLN9708, compared with bortezomib, has improved pharmacokinetics, pharmacodynamics, and antitumor activity in preclinical studies.

Ixazomib citrate (MLN9708) is a prodrug of Ixazomib (MMLN-2238). MLN9708 is an orally bioavailable second generation proteasome inhibitor (IC50 of 3.4 nM ) with potential antineoplastic activity.

MLN2238 suppresses the chymotrypsin-like proteolytic (β5) site of the 20S proteasome(Ki50=0.93 nM, IC50=3.4 nM/). The biologically active form of MLN9708 (Ixazomib Citrate) is MLN2238 in aqueous solutions or plasma.

VPC-16606 is a potent and selective inhibitor of ERα-dependent cell growth and gene expression. VPC-16606 prevents the interaction between ERα-LBD and SRC-3 fusion proteins in a dose-dependent manner.
