MK-2866 and Modafinil Interaction

Avoid
Mechanism-based 64% confidence

MK-2866 and Modafinil have a potentially harmful interaction with 64% confidence. Both MK-2866 and Modafinil carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently. These compounds primarily affect different organ systems.

Compound Profiles

MK-2866

Selective Androgen Receptor Modulator | Muscle Wasting Research

MK-2866 binds to the androgen receptor (AR) with high affinity and selectivity, functioning as a partial agonist in muscle and bone tissue. Upon binding, the MK-2866-AR complex undergoes a conformational change that promotes nuclear translocation and interaction with androgen response elements (AREs) on DNA, activating transcription of genes involved in protein synthesis, nitrogen retention, and myogenic differentiation.

Modafinil

Eugeroic | Wakefulness & Cognitive Enhancement

The exact mechanism of action of modafinil is not fully understood, which distinguishes it from most prescription stimulants. The primary mechanism appears to involve inhibition of the dopamine transporter (DAT), leading to increased extracellular dopamine concentrations in the nucleus accumbens and cortical regions.
