Sulfotransferase (SULT1) 抑制因子

Sulfotransferase signaling involves the catalytic process in which sulfotransferase enzymes facilitate the conjugation of sulfate groups to a wide range of molecules, including hormones, neurotransmitters, drugs, and xenobiotic compounds. These enzymes are found in the cytosol of cells and exhibit variations in their distribution across tissues and their specific preferences for substrates. The addition of sulfate groups to these molecules plays a crucial role in regulating their biological activity and pharmacokinetics. Sulfotransferases are key players in modulating the bioavailability and functionality of various endogenous and exogenous compounds, contributing to the fine-tuning of cellular responses and metabolic pathways. Dysregulation of sulfotransferase signaling can have significant implications for drug metabolism and the modulation of physiological processes.

Sulfotransferase (SULT) inhibitors represent a class of chemical compounds that have garnered significant attention and biochemistry due to their ability to modulate the activity of sulfotransferase enzymes, particularly those belonging to the SULT1 subfamily. Sulfotransferases are a group of enzymes involved in a phase II metabolic reaction known as sulfation, which plays a crucial role in the regulation of various endogenous and exogenous compounds within the body. The primary function of sulfotransferases is to catalyze the transfer of a sulfate group from the universal sulfate donor, 3'-Phosphoadenosine-5'-phosphosulfate (PAPS), onto specific substrates, rendering them more hydrophilic and facilitating their elimination from the body.
