5、rylation at 1 M and almost completely at 3 M, in A2780 tumor cellline. PHA-793887 (1 M) partially inhibits phosphorylation of the Cdk2 substrates Rb and NPM in A2780 tumorcell line. PHA-793887 (6 M) significantly inhibits Rb and NPM phosphorylation in MCF7 cell line 1. PHA-793887 shows cytotoxic act

6、ivities against leukemic cell lines in vitro, with IC50 ranging from 0.3 to 7 M. Incolony assays, PHA-793887 is highly cytotoxic for leukemia cell lines, with an IC50 50 in the 5 to 140 nM range3.體內(nèi)研究 PHA-793887 induces tumor growth inhibition in the range of 50% at dose of 15 mg/kg to 75% at dose o

7、f 30mg/kg in CD-1 nude mice. PHA-793887 (30 mg/kg, i.v.) also induces significant downregulation of the 58-genepanel in the skin of CD-1 mice 1. PHA-793887 (20 mg/kg, i.v.) induces tumor regression in the HL60 model. Inthe K562 model, PHA-793887 significantly reduces tumor growth. Moreover, PHA-7938

For each cell line, preliminarydoseresponse curves are performed to establish the cell-concentration range, giving a line

9、ar relationshipwith fluorescence. For cell lines, 5,000 to 20,000 cells are plated in 200 L complete medium in 96-wellplates, in the presence or absence of increasing doses of drugs (0.0110 M). For ALL-2 and AML-PSleukemias 10 105 cells/well are plated in StemSpanSFEM medium and treated with the sam

Peripheral blood mononuclear cells and cord blood CD34+ cells are plated 1 105 cells/wellin presence or absence of 1 g/mL phytohemagglutin or growth factor cocktail (50 ng/mL stem cell factor, 20ng/mL each of granulocyte-macrophage colony-stimulating factor, granulocyt

11、e colony-stimulating factor,interleukin-3, interleukin-6, and 3 U/mL erythropoietin), respectively. In all cases, after 48 hours culture, 1/10volume Alamar blue solution is added and incubated overnight. The plates are then read in a fluorimeter withexcitation at 535 nm and emission at 590 nm. Cytot

12、oxicity is calculated as percentage of fluorescence withrespect to untreated control, after subtracting for background fluorescence in absence of cells.MCE has not independently confirmed the accuracy of these methods. They are for reference only.Animal 107 HL60 and K562 cells are inoculated subcuta

13、neously in SCID mice. Animals are randomized in sevenAdministration 3 mice per group. PHA-793887 is administered at 20 mg/kg intravenous (IV) once a day, continuously for 10days (from day 9 to day 18) in HL60 model and with a two 5-day cycles (from day 9 to day 13 and from day17 to day 21) in K562-b

14、earing mice. Glivec is orally administered for 9 consecutive days from day 9 onwardin the K562 xenograft model. Tumor growth and net body weight are evaluated twice a week. The tumor2/3 Master of Small Molecules 您邊的抑制劑師www.MedChemEweight is calculated according to the following formula: tumor weight

15、 = length (mm) width2 (mm) /2. Theeffect of the anticancer treatment is determined as the delay in onset of an exponential growth of tumors.This delay (T C value) is defined as the difference of median time (in days) required for the tumors oftreatment (T) and control groups (C) to reach a predeterm

16、ined size. Toxicity is evaluated on the basis of thebody weight reduction.MCE has not independently confirmed the accuracy of these methods. They are for reference only.戶使本產(chǎn)品發(fā)表的科研獻(xiàn) Sci Transl Med. 2018 Jul 18;10(450). pii: eaaq1093. Harvard Medical School LINCS LIBRARYSee more customer validations o
