C18H24N2OS

Molecular Weight 316.46 CAS No. 148741-30-4
Solubility (25°C)* In vitro DMSO 36 mg/mL (113.75 mM)
Ethanol 3 mg/mL (9.47 mM)
Water Insoluble
In vivo (Add solvents to the product individually and in order)
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O
1.5mg/ml Taking the 1 mL working solution as an example, add 50 μL of 30 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Tyrphostin AG 879 potently inhibits HER2/ErbB2 with IC50 of 1 μM, 100- and 500-fold higher selective to ErbB2 than PDGFR and EGFR.
Targets
HER2-Neu [6]
(Cell-free assay)
Trk [6]
(Cell-free assay)
1.0 μM 10 μM
In vitro AG879 inhibits growth of FET6αS26X cells in a concentration-dependent manner. [1] AG879(10 nM) blocks the activation of PAK1 and suppresses RAS-induced malignant transformation of NIH 3T3 cells. AG879(<1 μM) inhibits the Tyr-phosphorylation of ERK and its association with PAK1 in v-Ha-RAS-transformed NIH 3T3 fibroblasts. [2] AG 879 dose-dependently reduce MCF-7 cell numbers and show already a significant effect at 0.4 mM through inhibiting DNA synthesis and mitotic. AG 879(<20 μM) inhibits activation of ERK-1/2 in MCF-7 cell. AG 879(5 μM) decreases expression of Hsp90 client proteins RAF-1 and HER-2. [3] AG879(20 μM) dramatically decreases proliferation with a variable increase in apoptosis in Cell lines from human leiomyosarcoma (HTB-114, HTB-115, HTB-88), rhabdomyosarcoma (HTB-82, TE-671), prostatic adenocarcinoma (PC-3), acute promyelocytic leukemia (HL-60) and histiocytic lymphoma (U-937). [4]
In vivo AG879(2 mg) induces a decrease in cancer growth in athymic NOD/SCID mice grafted with HTB-114 or HL-60. [4] AG 879(20 mg/kg) treatment keeps 50% of mice absolutely free of RAS-induced sarcomas, and dramatically reduces the size of the growing sarcomas in the nude mice carrying v-Ha-RAS transformed NIH 3T3 cells.

Protocol (from reference)

Cell Assay:

[3]

  • Cell lines

    MCF-7 cells

  • Concentrations

    20 μM

  • Incubation Time

    46 hours

  • Method

    Cells are grown in 96-well plates containing 100 μL medium per well. Ten microliters of MTT solution (5 mg/ml in PBS) is added to each well and incubation continued for 4 h at 37 °C. Subsequently, 100 μL 10% SDS in 0.01 M HCl is added. After incubation at 37°C overnight, absorption is measured at 550 nm in an ELISA reader using a reference filter of 690 nm.

Animal Study:

[5]

  • Animal Models

    nude mice carrying v-Ha-RAS transformed NIH 3T3 cells

  • Dosages

    20 mg/kg

  • Administration

    Intraperitoneally administrated on days 3, 5, 7, 10, 12, 14, and 17.
