Description of PD 145305

PD 145305 is an inactive analog of PD 150606, a potent and selective calpains inhibitor [1].

Calpain is a class of cytosolic cysteine protease that is activated by elevated intracellular calcium. Overactivation of calpain has been implicated in the pathophysiology of several degenerative conditions, including stroke, myocardial ischemia, neuromuscular degeneration, and cataract formation [1].

PD 145305 is an inactive analog of PD 150606, a potent and selective calpains inhibitor. PD 150606, an alpha-mercaptoacrylate derivative, inhibited μ-calpain and m-calpain with Ki values of 0.21 and 0.37 μM, respectively. PD 145305 was inactive at concentrations up to 500 μM. In human leukemic Molt-4 cells, PD150606 inhibited a-spectrin proteolysis in a dose-dependent way and virtually eliminated the formation of the 145-kDa fragment at 10 μM, whereas PD145305 did not attenuate a-spectrin breakdown product formation. In fetal rat cerebrocortical cultures subjected to a combination of hypoxia and hypoglycemia, PD150606 significantly inhibited the release of lactate dehydrogenase, whereas PD145305 was ineffective. PD150606, but not PD145305, was found to make cerebral glutamatergic neurons more resistant to hypoxic/hypoglycemic challenge [1].

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 saline, 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.
