GDC-0941 is a potent and selective oral inhibitor of the class I PI3K. GDC-0941 demonstrated broad spectrum of activity in breast, ovarian, lung, and prostate cancer models. Studies has also shown GDC
-0941 may enhance anti-tumor activity of Docetaxel (D494420) in human breast cancer models. | [Definition]
ChEBI: A sulfonamide composed of indazole, morpholine, and methylsulfonyl-substituted piperazine rings bound to a thienopyrimidine ring. | [Description]
GDC-0941/Pictilisib (957054-30-7) is a potent and selective inhibitor of class I phosphatidylinositol-3-kinases (PI3K) with significant antitumor activity – IC50’s: PI3Kα = 3nM, PI3Kβ = 33 nM, PI3Kδ = 3 nM, PI3Kγ = 75 nM.1,2?? GDC-0941 is the chemical probe of choice for the pan-inhibition of class I PI3K’s.3?Currently in clinical trials.4 | [Synthesis]
Step 1: 4-(2-chloro-6-((4-(methylsulfonyl)piperazin-1-yl)methyl)thieno[3,2-d]pyrimidin-4-yl)morpholine (Compound 0113, 800 mg, 1.86 mmol), pinacol ester of 1H-indazole-4-boronic acid (0107-3, 500 mg, 2.04 mmol), sodium bicarbonate (470 mg. 5.58 mmol), sodium bicarbonate (470 mg, 5.58 mmol), and bis(triphenylphosphine)palladium(II) chloride (80 mg, 0.093 mmol) were dissolved in a solvent mixture of toluene (20 mL), ethanol (12 mL), and water (5.6 mL). The reaction system was replaced by nitrogen and then heated at 120 °C for 1 h under microwave radiation. After completion of the reaction, the reaction mixture was partitioned between dichloromethane and water. The organic layer was separated, washed with brine, dried over anhydrous magnesium sulfate, filtered and concentrated. The resulting crude product was purified by silica gel column chromatography (eluent: dichloromethane containing 2% methanol, v/v) to afford 2-(1H-indazol-4-yl)-6-(4-methanesulfonylpiperazin-1-ylmethyl)-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (Compound 0114, 350 mg, 37% yield) as a white solid with a melting point of 148-149 °C. LC -MS: m/z 514 [M+H]+; 1H NMR (400 MHz, CDCl3): δ 2.70 (t, J = 4.4 Hz, 4H), 2.81 (s, 3H), 3.13 (t, J = 4.4 Hz, 4H), 3.92 (m, 6H), 4.09 (t, J = 5.6 Hz, 4H), 7.41 (s, 1H), 7.50 (m, 1H), 7.59 (d, J = 8.4 Hz, 1H), 8.28 (d, J = 6.8 Hz, 1H), 9.00 (s, 1H), 10.32 (br s, 1H). | [in vivo]
Pictilisib (GDC-0941) (150 mg/kg, p.o.) leads to tumor stasis in MCF7-neo/HER2-bearing animals model. Pictilisib (GDC-0941) and RP-56976 result in tumor regressions during the treatment period leading to enhanced antitumor responses[1]. Tumours in the Pictilisib (GDC-0941)-treated mice show a marked non-linear shrinkage, and when the Pictilisib (GDC-0941) treatment ceased, the tumours in the test cohort mice grow again[2]. Pictilisib (GDC-0941) (25 or 50 mg/kg) reduces tumor growth and PI3K and HIF-1 pathway activity in eGFP-FTC133 tumor-bearing mice[4]. | [target]
