Alofropodect
Alofropodect is an orally active, blood-brain barrier permeable phosphodiesterase 10A (PDE10A) inhibitor with IC50 values of 1 nM (Reference 1) and 35 nM (Reference 2). Alofropodect acts as a negative allosteric modulator of the M2 muscarinic receptor with an IC50 of 9.2 μM. Alofropodect alters cyclic nucleotide levels in basal ganglia circuits, inhibits the hydrolysis of cAMP and cGMP, and suppresses hERG potassium channel tail currents. Alofropodect induces catalepsy in rats and reverses injury-induced contralateral forelimb use impairment. Alofropodect can be used in research related to schizophrenia, Parkinson's disease, and levodopa-induced dyskinesia.

Description
|
PDE10A 1 nM (IC50) |
PDE10A 35 nM (IC50) |
In Vitro
Alofropodect (0.1-10 μM; 5 min) inhibits hERG tail current in hERG-HEK-293 transfected cells with an IC25 of 3.2 μM[1].
Alofropodect (0.0457-100 μM; 14 days) does not affect key cardiac spheroid health parameters up to 100 μM, but impairs DNA structure with an IC50 of 37.4 μM in human pluripotent cell-derived 3D cardiac spheroids[1].
Alofropodect (8 nM-60 μM; 72 h) is not cytotoxic at concentrations up to 60 μM in NCI-H1299, HepG2, and SH-SY5Y cell lines[1].

Parmacokinetics
In Vivo
Alofropodect (0.1-0.3 mg/kg; p.o.; single acute administration combined with Levodopa (HY-N0304)/Benserazide (HY-121275) for 16 consecutive days) dose-dependently improves sensorimotor deficits in 6-hydroxydopamine-lesioned rats[2].

Animal Model:Sprague-Dawley (male, ~300 g)[1]
-
Dosage:0.15 mg/kg; 0.3 mg/kg; 0.6 mg/kg; 2 mg/kg
-
Administration:p.o.; single dose
-
Result:Did not induce catalepsy at 0.15 mg/kg.
Induced a low cataleptogenic effect only at 210 min and 240 min post-administration at 0.3 mg/kg.
Induced catalepsy from 120 min to 240 min post-administration at 0.6 mg/kg, with effect less than positive control haloperidol.
Produced a strong cataleptogenic effect comparable to haloperidol at 2 mg/kg.
Confirmed minimum effective dose (MED) for catalepsy as 0.6 mg/kg via AUC data.
-
Animal Model:Wistar Han (male, initial body weight 270-300 g, unilateral medial forebrain bundle lesion with 6-hydroxydopamine)[2]
-
Dosage:0.1 mg/kg (acute single dose; chronic daily combined with L-DOPA/benserazide); 0.3 mg/kg (acute single dose; chronic daily combined with L-DOPA/benserazide)
-
Administration:p.o.; single acute dose; daily for 16 days (combined with L-DOPA/benserazide)
-
Result:Dose-dependently reversed impaired forelimb use in the stepping test after acute administration.
Completely restored forelimb use symmetry in the cylinder test during the second post-dose testing session at 0.3 mg/kg acute dose.
Did not affect vibrissae test deficits or lesion-induced catalepsy at either acute dose.
Significantly improved impaired forelimb performance in the vibrissae test when combined acutely with L-DOPA at 0.1 mg/kg.
Reduced L-DOPA-induced contralateral rotations when combined acutely with L-DOPA at 0.3 mg/kg.
Completely reversed forelimb asymmetry in the vibrissae test after chronic combined treatment at 0.3 mg/kg.
Did not alter L-DOPA's antiparkinsonian effects in the stepping, catalepsy, or rotation tests at either chronic dose.
Significantly improved impaired forelimb use in the stepping test in the OFF phase post-chronic treatment at 0.3 mg/kg combined with L-DOPA compared to lesioned rats.

Solvent & Solubility
In Vitro:
DMSO : 25 mg/mL (73.23 mM; ultrasonic and warming and heat to 60°C; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (7.32 mM); Suspended solution
This protocol yields a suspended solution of ≥ 2.5 mg/mL (saturation unknown). Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
