New to Minoxidil? There is a guide in the encyclopedia. Read the guide → Studysummary In this study, researchers found that both thermolabile and thermostable forms of phenol sulfotransferase contribute to the sulfation of minoxidil, emphasizing the need to consider both enzymes in assessing sulfation in human tissues. Our plain-language summary of this paper — not a Tressless recommendation.
The study investigated the role of thermolabile phenol sulfotransferase in the sulfation of minoxidil, a hair growth stimulator, using a human liver cDNA clone. It was previously thought that only the thermostable form of the enzyme catalyzed this reaction. However, the research confirmed that the thermolabile form also sulfated minoxidil, similar to its activity with dopamine. This finding suggested that both enzyme forms should be considered when assessing the contribution of human tissue sulfotransferase to minoxidil metabolism.
