General description

Trichostatin A (TSA) is a potent and specific inhibitor of histone deacetylase (HDAC) activity. It is an antifungal antibiotic with cytostatic and differentiating properties in mammalian cell culture.

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

Trichostatin A (TSA) 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. Trichostatin A serves as an epigenetic modifier.

Features and Benefits

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.

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

Epigenetic modifications are thought to occur through two key interconnected processes—DNA methylation and the covalent modification of histones.

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.

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.

We offer a variety of small molecule research tools, such as transcription factor modulators, inhibitors of chromatin modifying enzymes, and agonists/antagonists for target identification and validation in gene regulation research; a selection of these research tools is shown below.
