  • Antibiotic.
  • Antibacterial and antifungal properties [1, 2].
  • Forms a complex with FKBP12 and inhibits the mammalian target of rapamycin (mTOR). Inhibits the response to interleukin-2 (IL-2), and thereby blocks activation of T and B cells [3, 5, 6, 11].
  • Potent immunosuppressant [4, 10] used as an alternative to calcineurin inhibitors [12].
  • Restricts the proliferation of smooth-muscle cells by blocking cell cycle progression at the G1/S transition [7, 13].
  • Anti-proliferative. Antitumor compound [14, 15].
  • Apoptosis enhancer. Activator of autophagy both in vitro and in vivo [8, 9].
  • Anti-HIV and anti-aging compound [16, 17].
  • Neuroprotective [18].
  • Suppressor for self-renewal and vascular differentiation potential in hemangioma stem cells [19].
  • mTORC1 inhibitor [20].
