hdac in 26

HDAC-IN-26, a highly selective class I HDAC inhibitor, has an EC50 value of 4.7 nM.

HDAC6-IN-26 (compound 23) is an effective HDAC6 inhibitor [1].

RO314724 is a HDAC inhibitor. RO314724 is also a a reversible, tightly binding, MMP inhibitor with a Ki of 26 nm. Matrix metalloproteinases (MMPs) belong to the key enzymes of the proteolytic destruction of cartilage matrix during chronic rheumatic diseases. Ro314724 displayed MMP-proteoglycanase inhibitory activity both in vitro and ex vivo and proved to be not harmful to the morphology, viability and proteoglycan biosynthesis of bovine articular cartilage explants.

HDAC/HSP90-IN-4 significantly inhibited HDAC and HSP90 activity, with compound 20 (HDACIC50= 194 nM; HSP90αIC50= 153 nM) and compound 26 ((HDACIC50= 360 nM; HSP90αIC50= 77 nM) having the strongest HDAC and HSP90α inhibition. effect. Both compounds induced HSP90 expression and down-regulated HSP90 client proteins, which play an important role in the regulation of cancer cell survival and invasion.
