Biological Data

Biological description


Rapamycin is an mTOR inhibitor and potent immunosuppressant. It complexes with FKBP12 to bind mTORC1 to inhibit mTOR activity and block subsequent activation of p70 s6 kinase (IC50 = 50 pM).

Active in vivo.

Uses and applications

Rapamcyin shows a variety of bioloigical actions. E.g it induces autophagy and apoptosis.

Promotes hPSC differentiation to blood progenitor and mesendoderm cells.

It can also be used in inducible CRISPR/Cas9 systems to enable inducible gene editing.

Used as a chemical dimerizer in Chemically-inducible dimerization (CID).

As mTOR is a central inflammation regulator, rapamycin has recently been investigated as part of cytokine storm / COVID-19 related research.

Solubility & Handling
