S1105 LY294002 LY294002 (SF 1101, NSC 697286) は人工的に合成した分子としては初めての PI3Kα/δ/β 阻害剤であり、IC50 はそれぞれ 0.5 μM/ 0.57 μM/ 0.97 μM です。溶液中でウォルトマンニン (wortmannin) よりも安定しています。クラス I PI3K および PI3K 関連キナーゼだけでなく、一見 PI3K ファミリーには無関係にある新規のターゲットにも結合します。LY294002 は CK2 阻害剤でもあり、IC50 は 98 nM です。また LY294002 はオートファゴソーム (autophagosome) の形成をブロックする一方で、DNA-PKcs を非特異的に阻害することによりオートファジー (autophagy) を活性化し、アポトーシス (apoptosis) を誘導します。

S1273 Amarogentin

Amarogentin (AG), a secoiridoid glycoside mainly extracted from Swertia and Gentiana roots, exhibits anti-oxidative, anti-tumour, and anti-diabetic activities. Amarogentin is an agonist for the bitter taste receptor TAS2R1 and inhibits in LAD-2 cells substance P-induced production of newly synthesized TNF-α. Amarogentin induces apoptosis in human gastric cancer cells (SNU-16) through G2/M cell cycle arrest and PI3K/Akt signalling pathway. Amarogentin (AG) interacts with the α2 subunit of AMP-activated protein kinase (AMPK) and activates the trimeric kinase with EC50 of 277 pM.

E4702New SRX3177 SRX3177 is a potent triple inhibitor targeting CDK4/6, PI3K, and BRD4, with IC50 values of 33 nM for BRD4 BD1, 89 nM for BRD4 BD2, 79 nM for PI3Kα, 83 nM for PI3Kδ, 3.18 μM for PI3Kγ, <2.5 nM for CDK4, and 3.3 nM for CDK6. By simultaneously inhibiting these key pathways, SRX3177 disrupts cancer cell signalling and exhibits significant cytotoxic effects in tumors.
S3241 Loureirin A Loureirin A is a flavonoid extracted from the red resin of the herbs of Dracaena cochinchinensis, which is known as Dragon's Blood. Loureirin A inhibits platelet activation by an impairment of PI3K/Akt signaling. Loureirin A inhibits Akt phosphorylation.
S7865 740 Y-P (PDGFR 740Y-P) 740 Y-P (PDGFR 740Y-P, 740YPDGFR) is a cell-permeable phosphopeptide activator of PI3K.

S3294 Demethyl-Coclaurine Demethyl-Coclaurine (Higenamine, Norcoclaurine), the key component of the Chinese herb aconite root, is a beta-2 adrenergic receptor (β2-AR) agonist. Demethyl-Coclaurine stimulates AKT phosphorylation and requires PI3K activation for the anti-apoptotic effect in cardiomyocytes.

E2947 Recilisib Recilisib (ON01210, EX-RAD) is a radioprotectant that activates the activity of AKT and PI3K in cells. It has been studied as prophylactic (use prior to radiation exposure) and therapeutic (after exposure to radiation) drug.
E1579 UCL-TRO-1938 UCL-TRO-1938 is a potent allosteric activator of PI3Kα. UCL-TRO-1938 can induce cell proliferation and has cardioprotective and neural regeneration effects.
S5383 Erucic acid Erucic acid (cis-13-docosenoic acid) is a monounsaturated omega-9 fatty acid used as mineral oil and a precursor to biodiesel fuel.
E0785 YS-49 YS-49 is a PI3K/Akt (a downstream target of RhoA) activator, to reduce RhoA/PTEN activation in the 3-methylcholanthrene-treated cells, inhibits angiotensin II (Ang II)-stimulated proliferation of VSMCs via induction of heme oxygenase (HO)-1, also is an isoquinoline compound alkaloid, has a strong positive inotropic action through activation of cardiac β-adrenoceptors.

S4572 Homosalate Homosalate (HMS, Homomenthyl salicylate) is an organic ultraviolet filter used in most sunscreens but has been reported to be toxic to marine organisms. Homosalate aggravates the invasion of human trophoblast cells as well as regulates intracellular signaling pathways including PI3K/AKT and MAPK pathways.
E2391 α-Linolenic acid α-Linolenic acid, an essential fatty acid isolated from seed oils, affects the process of thrombotic through the modulation of PI3K/Akt signaling, and possesses the anti-arrhythmic properties.
S6885 Ailanthone Ailanthone (AIL, Δ13-Dehydrochaparrinone), a natural anti-hepatocellular carcinoma (HCC) component in Ailanthus altissima, induces G0/G1-phase cell cycle arrest by decreasing expression of cyclins and CDKs and increases expression of p21 and p27. Ailanthone triggers DNA damage characterized by activation of the ATM/ATR pathway. Ailanthone induces apoptosis which is mitochondrion-mediated and involves the PI3K/AKT signaling pathway in Huh7 cells. Ailanthone is also a potent inhibitor of both full-length Androgen Receptor (AR-FL) and constitutively active truncated AR splice variants (AR-Vs, AR1-651) with IC50 of 69 nM and 309 nM, respectively.
