PP1 is a nano-molar inhibitor of Lck and FynT, inhibits anti-CD3-induced protein-tyrosine kinase activity in T cells (IC50, 0.5 μM), demonstrates selectivity for Lck and FynT over ZAP-70, and preferentially inhibits T cell receptor-dependent anti-CD3-induced T cell proliferation (IC50, 0. 5 μM) over non-T cell receptor-dependent phorbol 12-myristate 13-acetate/interleu-kin-2 (IL-2)-induced T cell proliferation. PP1 (1 μM) selectively inhibits the induction of the IL-2 gene, but not the granulocyte-macrophage colony-stimulating factor or IL-2 receptor genes. PP1 also inhibits Src (IC50, 170 nM) and Hck (IC50, 20 nM). PP1 is 50–100-fold less active in the inhibition of A-431 epidermal growth factor receptor autophosphorylation (IC50, 0.25 μM). [1] PP1 also inhibits Kit and Bcr-Abl tyrosine kinases with IC50 of ∼75 nM and 1 μM, respectively. PP1 completely abrogates the proliferation of M07e cells in response to SCF with IC50 of 0.5–1 μM. PP1 (1 μM) inhibits SCF-induced c-Kit autophosphorylation in intact cells and blocks the activation of mitogen-activated protein kinase and Akt. PP1 inhibits the activity of mutant constitutively active forms of c-Kit (D814V and D814Y) found in mast cell disorders, and triggers apoptosis in the rat basophilic leukemia cell line RBL-2H3 that expresses mutant c-Kit. PP1 reduces the constitutive activation of signal transducer and activators of transcription 5 and mitogen-activated protein kinase and triggeres apoptosis in FDCP1 cells expressing Bcr-Abl. [2]

Calculation results:

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
