IC50 & Target

α-synuclein

 

In Vitro

Cinpanemab is highly selective for aggregated forms of α-syn with at least an 800-fold higher apparent affinity for fibrillar versus monomeric recombinant α-syn and a strong preference for human PD brain tissue[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Cinpanemab (30 mg/kg; i.p.) improves PD-like phenotypes in α-syn PFF inoculation mouse models [2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: C57BL/6JRccHsd WT mice, transgenic M83 mice expressing human α-syn A53T, and transgenic bacterial artificial chromosome mice expressing human α-syn A53T were anesthetized and stereotaxically injected with α-syn preformed fibrils (PFFs) into the right forebrain[2]
Dosage: 30 mg/kg
Administration: Intraperitoneal (i.p.) injections 2-3 times prior to α-syn PFF injection and weekly post-injection until time of sacrifice
Result: Attenuated the spreading of α-syn pathology, rescued motor impairments, and reduced the loss of dopamine transporter density in dopaminergic terminals in striatum.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
