MK-2866 and Rapamycin Interaction

Monitor
Mechanism-based 47% confidence

MK-2866 and Rapamycin have an interaction requiring monitoring for interaction with 47% confidence. Both MK-2866 and Rapamycin negatively affect lipid profiles. Combined use may significantly worsen HDL/LDL ratios. Include lipid support and get bloodwork mid-cycle. 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.

Rapamycin

mTOR Inhibitor | Longevity & Immunosuppression

Rapamycin exerts its effects by binding to the intracellular protein FKBP12, forming a complex that directly and specifically inhibits mechanistic target of rapamycin complex 1 (mTORC1). mTORC1 is a master nutrient-sensing kinase that integrates signals from growth factors, amino acids, energy status, and stress to regulate cell growth, proliferation, and metabolism.
