Taselisib (GDC 0032)^New

Taselisib (GDC 0032, RG7604) is a potent, next-generation β isoform-sparing PI3K inhibitor targeting PI3Kα/δ/γ with K_i of 0.29 nM/0.12 nM/0.97nM, >10 fold selective over PI3Kβ.
Pilaralisib (XL147)^New

Pilaralisib (XL147) is a selective and reversible class I PI3K inhibitor for PI3Kα/δ/γ with IC50 of 39 nM/36 nM/23 nM in cell-free assays, less potent to PI3Kβ. Phase 1/2.
LY294002

LY294002 (SF 1101, NSC 697286) is the first synthetic molecule known to inhibit PI3Kα/δ/β with IC50 of 0.5 μM/0.57 μM/0.97 μM, respectively; more stable in solution than Wortmannin, and also blocks autophagosome formation. It not only binds to class I PI3Ks and other PI3K-related kinases, but also to novel targets seemingly unrelated to the PI3K family. LY294002 also inhibits CK2 with IC50 of 98 nM. LY294002 is a non-specific DNA-PKcs inhibitor and activates autophagy and apoptosis.
3-Methyladenine (3-MA)

3-Methyladenine (3-MA, NSC 66389) is a selective PI3K inhibitor for Vps34 and PI3Kγ with IC50 of 25 μM and 60 μM in HeLa cells; blocks class I PI3K consistently, whereas suppression of class III PI3K is transient, and also blocks autophagosome formation. 3-Methyladenine (3-MA) is successfully used to suppress mitophagy. Solutions of 3-MA are best fresh-prepared by heating.
Idelalisib (CAL-101, GS-1101)

Idelalisib (CAL-101, GS-1101) is a selective p110δ inhibitor with IC50 of 2.5 nM in cell-free assays; shown to have 40- to 300-fold greater selectivity for p110δ than p110α/β/γ, and 400- to 4000-fold more selectivity to p110δ than C2β, hVPS34, DNA-PK and mTOR. Idelalisib also stimulates autophagy.
Wortmannin (KY 12420)

Wortmannin (KY 12420, SL-2052, BRN 0067676, NSC 627609) is the first described PI3K inhibitor with IC50 of 3 nM in a cell-free assay, with little selectivity within the PI3K family. Wortmannin blocks autophagosome formation and potently inhibits DNA-PK/ATM with IC50 of 16 nM and 150 nM in cell-free assays. Wortmannin also inhibits PLK1 activity.
Dactolisib (BEZ235)

Dactolisib (BEZ235, NVP-BEZ235) is a dual ATP-competitive PI3K and mTOR inhibitor for p110α/γ/δ/β and mTOR(p70S6K) with IC50 of 4 nM /5 nM /7 nM /75 nM /6 nM in cell-free assays, respectively. Inhibits ATR with IC50 of 21 nM in 3T3^TopBP1-ER cell. Dactolisib induces autophagy and suppresses HIV-1 replication. Phase 2.
Buparlisib (BKM120)

Buparlisib (BKM120, NVP-BKM120) is a selective PI3K inhibitor of p110α/β/δ/γ with IC50 of 52 nM/166 nM/116 nM/262 nM in cell-free assays, respectively. Reduced potency against VPS34, mTOR, DNAPK, with little activity to PI4Kβ. Buparlisib induces apoptosis. Phase 2.

In vivo

In both PC-3 and MCF-7 neo/HER2 xenograft models, GDC-0980 at a dose of 1 mg/kg, exhibits significant antitumor activity by causing tumor growth delay. Furthermore, GDC-0980 results in tumor stasis or regressions at the maximum tolerated dose of 7.5 mg/kg. ^[1] In mice, intravenous GDC-0980 administration at 1 mg/kg leads to low clearance (Cl_p: 9.2 mL/min/kg, V_ss: 1.7 L/kg). While, oral administration at 5 mg/kg in 80% PEG400 and at 50 mg/kg as a crystalline suspension in 0.5% methylcellulose/0.2% Tween-80 also results in favorable pharmacokinetic parameters. ^[1]

Protocol (from reference)

Kinase Assay:^[1]	Enzymatic activity: Enzymatic activity of the Class I PI3K isoforms is measured using a fluorescence polarization assay that monitors formation of the product 3,4,5-inositoltriphosphate molecule as it competes with fluorescently labeled PIP3 for binding to the GRP-1 pleckstrin homology domain protein. An increase in phosphatidyl inositide-3-phosphate product results in a decrease in fluorescence polarization signal as the labeled fluorophore is displaced from the GRP-1 protein binding site. Class I PI3K isoforms are expressed and purified as heterodimeric recombinant proteins. PI3K isoforms are assayed under initial rate conditions in the presence of 10 mM Tris (pH 7.5), 25 μM ATP, 9.75 μM PIP2, 5% glycerol, 4 mM MgCl₂, 50 mM NaCl, 0.05% (v/v) Chaps, 1 mM dithiothreitol, 2% (v/v) DMSO at the following concentrations for each isoform: PI3Kα,β at 60 ng/mL; PI3Kγ at 8 ng/mL; PI3Kδ at 45 ng/mL. After assay for 30 minutes at 25°C, reactions are terminated with a final concentration of 9 mM EDTA, 4.5 nM TAMRA-PIP3, and 4.2 μg/mL GRP-1 detector protein before reading fluorescence polarization on an Envision plate reader. IC50s are calculated from the fit of the dose−response curves to a 4-parameter equation.Human recombinant mTOR(1360−2549) is expressed and purified from insect cells and assayed using a Lanthascreen fluorescence resonance energy transfer format in which phosphorylation of recombinant green fluorescent protein (GFP)-4-EBP1 is detected using a terbium-labeled antibody to phospho-threonine 37/46 of 4-EBP1. Reactions are initiated with ATP and conducted in the presence of 50 mM Hepes (pH 7.5), 0.25 nM mTOR, 400 nM GFP-4E-BP1, 8 μM ATP, 0.01% (v/v) Tween 20, 10 mM MnCl₂, 1 mM EGTA, 1 mM dithiothreitol, and 1% (v/v) DMSO. Assays are conducted under initial rate conditions at room temperature for 30 minutes before terminating the reaction and detecting product in the presence of 2 nM Tb-anti-p4E-BP1 antibody and 10 mM EDTA. Dose−response curves are fit to an equation for competitive tight-binding inhibition and apparent Ki' s are calculated using the determined K_m for ATP of 6.1 μM.
Cell Research:^[1]	Cell lines: PC3 and MCF7.1 Concentrations: 0 to 10 μM Incubation Time: 72 hours or 96 hours Method: Antiproliferative cellular assays are conducted using PC3 and MCF7.1 human tumor cell lines. MCF7.1 is an in vivo selected line and originally derived from the parental human MCF7 breast cancer cell line. Cell lines are cultured in RPMI supplemented with 10% fetal bovine serum, 100 units/mL penicillin, and 100 μg/mL streptomycin, 10 mM HEPES, and 2 mM glutamine at 3°C under 5% CO₂. MCF7.1 cells or PC3 cells are seeded in 384-well plates in media at 1000 cells/well or 3000 cells/well, respectively, and incubated overnight prior to the addition of GDC-0980 to a final DMSO concentration of 0.5% v/v. MCF7.1 cells and PC3 cells are incubated for 3 days and 4 days, respectively, prior to the addition of CellTiter-Glo reagen and reading of luminescence using an Analyst plate reader. For antiproliferative assays, a cytostatic agent such as aphidicolin and a cytotoxic agent such as staurosporine are included as controls. Dose−response curves are fit to a 4-parameter equation and relative IC50s are calculated using Assay Explorer software. (Only for Reference)
Animal Research:^[1]	Animal Models: PC3 and MCF7.1 cells are injected s.c. into the right hind flank of athymic nu/nu (nude) mice. Dosages: ≤7.5 mg/kg Administration: Administered via p.o. (Only for Reference)
