Gedatolisib CAS 1197160-78-3
Dual PI3K / mTOR Kinase Inhibitor (PF-05212384, PKI-587)
Gedatolisib (CAS 1197160-78-3), also PF-05212384 / PKI-587, is a potent, balanced dual inhibitor of class I PI3K isoforms and mTOR kinase with cellular IC50s of ~0.4 nM (PI3Kalpha), 5.4 nM (PI3Kgamma) and 1.6 nM (mTOR). It simultaneously shuts down both arms of the PI3K/Akt/mTOR oncogenic axis. Molecular formula C32H41N9O4, MW 615.73. Research-grade with COA.

Key Molecular Targets & Pathway Nodes
Gedatolisib hits both limbs of the PI3K/Akt/mTOR axis at the kinase level — a broader blockade than rapalogs, which only allosterically inhibit mTORC1.
How Gedatolisib Works: Simultaneous PI3K and mTOR Kinase Blockade
Gedatolisib attacks both catalytic nodes of the oncogenic PI3K/Akt/mTOR network
PI3K Catalytic Inhibition
Gedatolisib binds the ATP sites of class I PI3K catalytic subunits (most potently p110alpha, also gamma/delta), blocking conversion of PIP2 to PIP3 at the membrane. This starves downstream AKT of its membrane-docking lipid, blunting AKT Thr308 and Ser473 phosphorylation even before mTORC2 is engaged.
mTOR Kinase Inhibition
Distinct from rapalogs, gedatolisib directly inhibits the mTOR kinase domain, suppressing both mTORC1 (S6K/4E-BP1) and mTORC2 (AKT Ser473) outputs. This dual coverage avoids the classic rapalog loophole where mTORC2-driven AKT feedback limits efficacy.
Collapse of Growth & Survival Signaling
With PI3K and mTOR both suppressed, downstream p70S6K, 4E-BP1 and PRAS40 phosphorylation fall, cap-dependent translation and cell-growth programs stall, and apoptosis/autophagy ensue in PIK3CA- or PTEN-altered cells. Notably, relief of mTORC1 feedback can transiently raise p-ERK, a marker studied in combination strategies.
⚖️ Gedatolisib vs Rapalogs vs Pan-PI3K
- Gedatolisib (this product)Dual PI3K + mTOR kinase; PI3Ka 0.4 / mTOR 1.6 nM
- Rapalogs (everolimus)Allosteric mTORC1 only; mTORC2/AKT feedback spared
- Pan-PI3K (BKM120)PI3K-only; leaves mTOR arm active (feedback)
- PI3K/mTOR (BEZ235)Dual but less balanced / tolerability-different
- Net CoverageBroadest single-agent PI3K/Akt/mTOR blockade
- Research UsePI3K-addicted & resistant solid tumors, combo studies
♻️ Downstream Biological Consequences
- AKTReduced p-AKT (T308 & S473)
- Translationp-S6K & p-4E-BP1 suppression
- Cell CycleG1 arrest; reduced cyclin D1
- SurvivalApoptosis / autophagy in PIK3CA/PTEN models
- FeedbackPossible p-ERK rise (combination rationale)
- AngiogenesisReduced HIF-1alpha / VEGF output
Research Applications & Models
Dual PI3K/mTOR blockade is a flagship strategy in PIK3CA-mutant and PTEN-loss oncology — and a window into resistance and combination science.
PI3K-Addicted Cancers
Studied in breast, endometrial, ovarian and prostate models bearing PIK3CA mutations or PTEN loss, where gedatolisib's dual blockade collapses the dominant survival axis. A reference dual inhibitor for pathway-addicted lines.
PIK3CA / PTENBreast Cancer Research
Investigated alone and with endocrine therapy, CDK4/6 inhibitors and HER2 blockers in hormone-receptor-positive and HER2+ contexts, probing synthetic-lethal and feedback combinations.
HR+ / HER2Resistance & Feedback Studies
Used to dissect mTORC1-release of AKT/ERK feedback that limits rapalogs and pan-PI3K drugs, informing rational combinations with MEK or CDK inhibitors.
Feedback LoopsAnti-Angiogenic Models
mTOR output controls HIF-1alpha and VEGF; gedatolisib is studied for tumor-vascular normalization and anti-angiogenic effects in xenografts.
HIF-1alpha / VEGFPI3K/Akt/mTOR Pathway Tool
A fiducial dual kinase inhibitor for Western panels (p-AKT, p-S6K, p-4E-BP1, p-PRAS40) and for discriminating PI3K-dependent from mTOR-dependent phenotypes.
Pathway ReadoutIn Vivo Efficacy Models
Evaluated in subcutaneous and orthotopic xenografts for tumor-growth inhibition, pharmacokinetic/pharmacodynamic (p-S6) correlation and tolerability.
Xenograft PDCombination Screening
Deployed in drug-combination matrices with taxanes, anti-HER2, CDK4/6 and MEK inhibitors to identify synergy and mitigate adaptive resistance.
Combo MatrixBiomarker Discovery
Paired with genomic/proteomic profiling to find predictors of response (PIK3CA mutation, PTEN loss, AKT activation) for patient-selection research.
