TAK-071 is a novel, potent and highly selective muscarinic acetylcholine receptor 1 (M1R) positive allosteric modulator (PAM). EC50 of TAK-071 M1R agonist activities is 520 nM. The muscarinic M1 receptor (M1R) is a promising target for treating cognitive impairment associated with cholinergic deficits in disorders such as Alzheimer's disease and schizophrenia.

Biological Activity
| ln Vivo | At a dose of 0.3 mg/kg, TAK-071 ameliorates the cognitive impairments caused by DB00747 in rats via increasing hippocampus myo-inositol monophosphate synthesis via M1R activation [1]. At 10 mg/kg, TAK-071 also induces diarrhea in rats [1]. Rats with DB00747-induced cognitive impairments showed considerable improvement when acetylcholinesterase inhibitors and TAK-071 (3 mg/kg) were combined [1]. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~135 mg/mL (~320.32 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.25 mg/mL (5.34 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 22.5 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.25 mg/mL (5.34 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 22.5 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.25 mg/mL (5.34 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 22.5 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
