生物活性

JF-NP-26, an inactive photocaged derivative of raseglurant, is the first caged mGlu5 receptor negative allosteric modulator. Uncaging of JF-NP-26 is elicited with light pulses in the visible spectrum (405 nm). JF-NP-26 induces light-dependent analgesia in models of inflammatory and neuropathic pain in freely behaving animals[1].

体外研究
(In Vitro)

The authors assessed the JF-NP-26-mediated negative allosteric modulation of mGlu5 receptor-induced responses to the orthosteric agonist quisqualate, by using an inositol phosphate (IP) accumulation assay. while JF-NP-26 didn’t show activity in dark conditions, its negative allosteric modulator (NAM) activity is rescued upon 405 nm visible light illumination (pIC50=7.1)[1].
Agonist challenge induced a robust mGlu5 receptor-mediated intracellular calcium rise both in dark and under 405 nm illumination, which was blocked by raseglurant. JF-NP-26 is unable to restrain agonist-mediated signalling in dark conditions, it abolished mGlu5 receptor-mediated intracellular calcium accumulation upon 405 nm irradiation, thus demonstrating a light-dependent negative allosteric modulator activity[1].

体内研究
(In Vivo)

JF-NP-26 (10 mg/kg; i.p.; irradiated at 405 nm (or dark) for 5 min) significantly increased pain thresholds in CCI mice only after thalamic irradiation[1].
JF-NP-26 (10 mg/kg; i.p.; at 405 nm light (or dark) for 5 min) shows light-dependent analgesic efficacy in neuropathic pain[1].
Systemic administration and in vivo photoactivation of JF-NP-26 does not impair memory in mouse[1].

Animal Model: Formalin animal model of pain adult male CD-1 mice[1]
Dosage: 10 mg/kg
Administration: I.p.; at 405 nm light (or dark) for 5 min
Result: Unable to promote antinociception in dark conditions, it elicited antinociception following direct hind paw irradiation both at phase I (5 min after formalin injection in the hind paw) and phase II (20–30 min after formalin injection).

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.
