Application

Trichostatin A (TSA) has been used during the production of cloned mouse embryos. TSA has also been used as a histone deacetylase (HDAC) inhibitor in LNCaP human prostate cancer cells, as well as in MON and HeLa cells.

Biochem/physiol Actions

Inhibits histone deacetylase at nanomolar concentrations; resultant histone hyperacetylation leads to chromatin relaxation and modulation of gene expression. May be involved in cell cycle progression of several cell types, inducing cell growth arrest at both G and G/M phases; may induce apoptosis. Enhances the efficacy of anticancer agents that target DNA.

Features and Benefits

This compound is a featured product for Apoptosis and Gene Regulation research. Discover more featured Apoptosis and Gene Regulation products. Learn more about bioactive small molecules for other areas of research at sigma.com/discover-bsm.

Preparation Note

Trichostatin A is soluble in methanol at 1.90 - 2.10 mg/ml and yields a clear, colorless to faint yellow/tan solution. It is also soluble in DMSO, DMF, acetonitrile, ethanol and lower alcohols. Trichostatin A is sparingly soluble in chloroform, ethyl acetate, acetone, and benzene. However, it is insoluble in water.

Carcinogenesis and Epigenetics

Cancer research has revealed that the classical model of carcinogenesis, a three step process consisting of initiation, promotion, and progression, is not complete.

Discover Bioactive Small Molecules for Cell Cycle Research

n proliferating cells, the cell cycle consists of four phases. Gap 1 (G1) is the interval between mitosis and DNA replication that is characterized by cell growth. Replication of DNA occurs during the synthesis (S) phase, which is followed by a second gap phase (G2) during which growth and preparation for cell division occurs. Together, these three stages comprise the interphase phase of the cell cycle. Interphase is followed by the mitotic (M) phase.

Discover Bioactive Small Molecules for Apoptosis

Apoptosis, or programmed cell death (PCD), is a selective process for the removal of unnecessary, infected or transformed cells in various biological systems. As it plays a role in the homeostasis of multicellular organisms, apoptosis is tightly regulated through two principal pathways by a number of regulatory and effector molecules.
