Obs: 1. Se till att vätskan är klar innan du tillsätter nästa lösningsmedel.
2. Se till att tillsätta lösningsmedlet/lösningsmedlen i ordning. Du måste se till att lösningen som erhålls i föregående tillsats är en klar lösning innan du fortsätter att tillsätta nästa lösningsmedel. Fysiska metoder som vortex, ultraljud eller varmt vattenbad kan användas för att underlätta upplösningen.

PF-477736 (128 nM) abrogates the camptothecin-induced DNA damage checkpoint in a dose-dependent manner in CA46 and HeLa cells. This compound effectively abrogates the -induced S-phase arrest with a corresponding increase in apoptotic cell populations in HT29 cells. This chemical (540 nM) enhances -induced cytotoxicity in a time- and dose-dependent manner in HT29 cells. It potentiates the growth-inhibitory activity of a panel of chemotherapeutic agents across a broad spectrum of p53-deficient human cancer cell lines in the MTT assay. Addition of this compound (360 nM) to -arrested cells induces a dramatic increase in the intensity of H2AX phosphorylation, reflecting a greater number of γ-H2AX molecules near sites of DNA damage. This chemical (0.5 nM) selectively blocks p73 and P53 phosphorylation in presence of curcumin in HL-60 cells. It (360 nM) suppresses -induced phosphorylation of histone H3 (Ser10) and Cdc25C (Ser216) and potentiates apoptosis in COLO205 cells. This compound (250 nM) combined with MK-1775 has marked synergistic cytotoxic activity in OVCAR-5 cells. It (250 nM) combined with MK-1775 causes accumulation of cells with a DNA content between 2N and 4N in OVCAR-5 cells. This chemical (250 nM) combined with MK-1775 causes premature mitosis before the end of DNA replication, with damaged DNA leading to apoptotic cell death in OVCAR-5 cells. |

Bindningsanalys

|
Analysen utförs i en 96-brunnsplatta under 20 minuter vid 30℃ i 0,1 ml analysbuffert innehållande 50 mM TRIS pH 7,5, 0,4 M NaCl, 4 mM PEP, 0,15 mM NADH, 28 enheter laktatdehydrogenas/ml, 16 enheter pyruvatkinas/ml, 3 mM DTT, 0,125 mM Syntide-2, 0,15 mM ATP och 25 mM magnesiumklorid. Analyserna initieras med 1 nM CHK1-kinasdomän. Hämningen av CHK1-aktivitet bestäms genom att mäta initiala hastigheter i närvaro av varierande koncentrationer av denna förening. Data analyseras med Enzyme Kinetic- och Excel-programvara och anpassas till en kinetisk modell för kompetitiv hämning för att erhålla ett Ki-värde. Kinasselektiviteten för denna kemikalie utvärderas genom att screena den vid 1 μM eller 10 μM mot en panel av cirka 100 proteinkinaser.

PF-477736 (4 mg/kg i.v.) results in terminal half-life (T1/2) of 2.9 hours, AUC of 5.72 μg×hr/mL and CLp of 11.8 mL/min/kg in rats. This compound dose-dependently enhances the antitumor activity of a maximum tolerated dose in the Colo205 xenograft mouse model. This chemical (12 mg/kg) induces an increase in the phosphorylation of histone H3 (Ser10) and of phospho-histone H2AX in the Colo205 xenograft mouse model. This compound (15 mg/kg i.p.) enhances induced tumor growth inhibition and tumor growth delay in COLO205 and MDA-MB-231 xenograft models. This chemical (10 mg/kg once daily i.p.) combined with MK-1775 (30 mg/kg twice a day oral) leads to greater tumor growth inhibition in mice bearing OVCAR-5 xenografts. |

Fråga 1:
Can you advise the vehicle suggested for S2904: 2% DMSO/40% PEG 300 at 5mg/ml, is it a suspension or clear solution? I wanted to know how to dissolve it for an i.p. injection in mice.
Svar:
It can dissolve in 2% DMSO/40% PEG 300 at 5mg/ml as a clear solution. If you are going to use this kind of vehicle, please dissolve this compound in DMSO clearly first, then add PEG300, then water.
