WAY-600 is a potent, ATP-competitive, and selective inhibitor of mTOR with an IC50 of 9 nM; it blocks mTORC1 P-S6K(T389) and mTORC2 P-AKT(S473) but not P-AKT(T308), and is selective for mTOR over PI3Kα (>100-fold) and PI3Kγ (>500-fold).

L-Leucine ((S)-Leucine) is one of nine essential amino acids in humans (provided by food), L-Leucine is important for protein synthesis and many metabolic functions. L-Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. L-Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. L-Leucine is available in many foods and deficiency is rare.

(+)-Usnic acid (D-Usnic Acid) is a naturally occurring dibenzofuran derivative found in several lichen species.

Torin 2(IC50=0.25 nM), a specific and effective mTOR inhibitor, is the 800-fold greater specific activity for mTOR than PI3K and improves pharmacokinetic properties. The EC50 of Torin 2 for ATM ATR DNA-PK inhibition is 28 nM 35 nM 118 nM, respectively.

PF-04691502 is a potent and selective inhibitor of PI3K and mTOR kinases with antitumor activity.

Everolimus (SDZ-RAD) is a potent mTOR inhibitor that binds to FKBP-12. It is used alone or in combination with calcineurin inhibitors.

Sapanisertib (INK 128) is an orally bioavailable inhibitor of raptor-mTOR (TOR complex 1 or TORC1) and rictor-mTOR (TOR complex 2 or TORC2) with potential antineoplastic activity.

Omipalisib (GSK2126458) is a small-molecule pyridylsulfonamide inhibitor of phosphatidylinositol 3-kinase (PI3K) with potential antineoplastic activity.
