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.

In vitro

PCI-32765 blocks BCR signaling in human peripheral B cells at concentrations that does not affect T cell receptor signaling. In DOHH2 cells, PCI-32765 inhibits autophosphorylation of Btk (IC50, 11 nM), phosphorylation of Btk’s physiological substrate PLCγ(IC50, 29 nM), and phosphorylation of a further downstream kinase, ERK (IC50, 13 nM). PCI-32765 is more than 1,000-fold selective for inhibition of antigen receptor signaling in B cells over T cells, and that only B-cell inhibition is sustained following short duration treatment.
In vivo

In mice with collagen-induced arthritis, orally administered PCI-32765 reduces the level of circulating autoantibodies and completely suppresses disease. PCI-32765 also inhibits autoantibody production and the development of kidney disease in the MRL-Fas(lpr) lupus model. The mean terminal plasma half-life of PCI-32765 following oral dosing in mice is 1.7 to 3.1 h.
