DHRS4L2 Inhibitors

DHRS4L2 inhibitors encompass a variety of chemical compounds that act through distinct biochemical mechanisms to diminish the functional activity of this enzyme. Some inhibitors target the enzyme's cofactor availability, for instance, by impacting the synthesis or regeneration of essential cofactors that DHRS4L2 relies on for its catalytic function, thereby indirectly reducing its activity. Others act by competitively inhibiting the enzyme, where the inhibitor molecules resemble the natural substrates of DHRS4L2 closely enough to compete for binding, thus preventing the enzyme from interacting with its true substrates. This competition can be due to either synthetic retinoids or endogenous retinoid analogs that mimic the structure of the retinoids DHRS4L2 is meant to reduce.

Further mechanisms of DHRS4L2 inhibition involve the modulation of metabolic processes that indirectly influence the enzyme's activity. Some compounds disrupt the metabolic balance of alcohols and aldehydes, which are related to the substrates and products of DHRS4L2, thereby affecting its function. Others may alter the enzyme's substrate availability by influencing the absorption and bioavailability of retinoids, which are key for DHRS4L2's action. Additionally, there are chemicals that can affect retinoid signaling and metabolism, potentially leading to a decrease in DHRS4L2's enzymatic activity through complex feedback and regulatory pathways that govern retinoid homeostasis.
