  3. Rhodojaponin VI

Rhodojaponin VI is an orally active diterpenoid compound found in hododendron molle G. Don
(Ericaceae) (RM). Rhodojaponin VI binds rat N-Ethylmaleimide-sensitive fusion (NSF) with a Kd of 1.03 μM. Rhodojaponin VI blocks the MDM2-Notch1 signalling pathway by reducing MDM2 and Notch1 expression. Rhodojaponin VI indirectly reduces Cav2.2 current intensity by inhibiting NSF-mediated Cav2.2 trafficking. Rhodojaponin VI alleviates glomerulonephritis progression and podocyte injury in passive heymann nephritis rats. Rhodojaponin VI also has antinociceptive effects. Rhodojaponin VI can be used for the researches of heymann nephritis and pain.

Description

Rhodojaponin VI is an orally active diterpenoid compound found in hododendron molle G. Don
(Ericaceae) (RM). Rhodojaponin VI binds rat N-Ethylmaleimide-sensitive fusion (NSF) with a Kd of 1.03 μM. Rhodojaponin VI blocks the MDM2-Notch1 signalling pathway by reducing MDM2 and Notch1 expression. Rhodojaponin VI indirectly reduces Cav2.2 current intensity by inhibiting NSF-mediated Cav2.2 trafficking. Rhodojaponin VI alleviates glomerulonephritis progression and podocyte injury in passive heymann nephritis rats. Rhodojaponin VI also has antinociceptive effects. Rhodojaponin VI can be used for the researches of heymann nephritis and pain[1][2][3].

In Vitro

Rhodojaponin VI ( pre-treated) partially blocks the MDM2-Notch1 signalling pathway in C5b-9-induced human podocyte cells by reducing C5b-9-induced MDM2 and Notch1 expression without altering p53 or Numb levels[1].
Rhodojaponin VI (0.01-100 μM; 20 min) enhances the thermal stability of NSF in rat DRG neuron lysates[2].
Rhodojaponin VI binds NSF directly (Kd = 1.03 ± 0.65 μM)[2].
Rhodojaponin VI (30 μM; 2-30 min) does not change Cav2.2 current intensity extracellularly but decreases it intracellularly in Cav2.2-HEK cells[2].
Rhodojaponin VI (30 μM; overnight) reverses the NSF-mediated increase in surface Cav2.2 expression and Cav2.2 current density in Cav2.2-HEK cells[2].

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

Western Blot Analysis[2]

Cell Line: Cav2.2-HEK cells
Concentration: 30 μM
Incubation Time: overnight
Result: Reversed the increase in surface Cav2.2 expression induced by NSF overexpression.
In Vivo

Rhodojaponin VI (0.02 mg/kg; p.o.; daily; 4 weeks) ameliorates podocyte injury and reduces proteinuria in male Sprague-Dawley rats with passive Heymann nephritis[1].
Rhodojaponin VI (0.001-0.05 mg/kg; i.p.; single dose) alleviates neuropathic pain in chronic constriction injury rats models[2].
Rhodojaponin VI (0.04-0.2 mg/kg, i.p.) exhibits potent antinociceptive effects in HOAC-induced writhing test in mice (with a writhe inhibition rate of 88.7%)[3].

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

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.
