MCAT Inhibitors

MCAT inhibitors, also known as mitochondrial complex I inhibitors, constitute a distinctive class of chemical compounds that exert their effects by targeting the mitochondrial electron transport chain. Mitochondrial complex I, or NADH:ubiquinone oxidoreductase, is a crucial enzyme complex situated in the inner mitochondrial membrane, playing a pivotal role in the electron transport process during cellular respiration. MCAT inhibitors specifically interfere with the function of this complex by disrupting the transfer of electrons from NADH to ubiquinone, impeding the normal flow of electrons within the respiratory chain.

MCAT inhibitors exhibit structural diversity, but they typically share the commonality of possessing functional groups that can interact with key catalytic sites within mitochondrial complex I. These inhibitors often feature lipophilic moieties, allowing them to readily traverse cellular membranes and reach their target within the mitochondria. By binding to specific sites on mitochondrial complex I, MCAT inhibitors disturb the redox reactions involved in energy production, leading to a disruption in the generation of the electrochemical gradient across the inner mitochondrial membrane. Consequently, this interference can have downstream effects on cellular bioenergetics and may impact various physiological processes.
