About Donepezil (Aricept)

Donepezil is a medication used for the treatment of dementia in people diagnosed with Alzheimer's disease. This medication can improve memory, attention, social interaction, speech, and cognitive clarity by increasing the level of a naturally occurring substance in the brain as it functions as an enzyme blocker, restoring the balance of neurotransmitters in the brain of the patients.

Properties of Donepezil (Aricept)

Donepezil, sold under the name Aricept, is a piperidine-derived acetylcholinesterase inhibitor with a molecular weight of 379.5 g/mol. It possesses a melting point of 223 to 227 °C, a boiling point of 527.9 °C, and a water solubility of 31mg/mL. This compound works by blocking the enzyme acetylcholinesterase, which breaks down acetylcholine in the brain. By inhibiting this enzyme, donepezil increases and extends the effects of acetylcholine at cholinergic synapses, leading to improved cholinergic transmission.

Manufacturing Process of Donepezil (Aricept)

The production process of donepezil involves several straightforward steps. Firstly, 5,6-dimethoxy-1-indanone and 1-benzyl-4-piperidinecarbox-aldehyde are combined through a condensation reaction in the presence of n-BuLi as a base and at a temperature of -78°C in the solvent mixture of tetrahydrofuran/ hexamethylphosphoric triamide. The condensation reaction results in the formation of an intermediate compound which is then subjected to a hydrogenation process using a palladium carbon catalyst. This process then results in the formation of the desired donepezil (Aricept).

Synthesis of Donepezil (Aricept)

The synthesis of Donepezil involves several chemical reactions, primarily focusing on building the central piperidine ring and attaching the appropriate functional groups necessary for its biological activity. Below are the key steps:

1.    Synthesis of the Piperidine Precursor

Starting Materials: 1-Bromo-3-chloropropane and pyridine.

Process: Alkylation of pyridine with 1-bromo-3-chloropropane to form a quaternary ammonium salt, followed by treatment with sodium amide to initiate a ring closure forming the piperidine structure.

Chemical Equation: Pyridine + Br (CH2) 3Cl → [(C5H5N) (CH2)3Cl] Br → Piperidine precursor

2.    Functionalisation of the Piperidine Ring

Starting Materials: Piperidine precursor from step 1, 4-nitrophenol, and an acylating agent (e.g., acetic anhydride).

Process: Acylation of the piperidine nitrogen followed by nucleophilic aromatic substitution with 4-nitrophenol to attach the phenolic group.

Chemical Equation: Piperidine precursor + Ac2O + 4-Nitrophenol → 4-Nitrophenyl-piperidine derivative

3.    Reduction of Nitro Group to Amino Group

Starting Materials: 4-Nitrophenyl-piperidine derivative.

Process: Catalytic hydrogenation to reduce the nitro group to an amino group.

Chemical Equation: 4-Nitrophenyl-piperidine derivative + H2 → 4-Aminophenyl-piperidine derivative

4.    Final Modification to Donepezil

Starting Materials: 4-Aminophenyl-piperidine derivative and an appropriate indanone derivative.

Process: Condensation reaction between the amine group and the indanone derivative to form Donepezil.

Chemical Equation: 4-Aminophenyl-piperidine derivative + Indanone derivative → Donepezil (Aricept)

Applications and Drivers of Donepezil (Aricept)

Donepezil finds primary applications in the early to middle stages of Alzheimer's disease, with a focus on improving cognitive functions such as memory, concentration, communication, and critical thinking. It is also one of the rare treatments for severe cases of Alzheimer's disease and can also help maintain functional abilities and manage behavioural issues like agitation and aggression in the later stages of the disease. With the rise of the global population, the prevalence of Alzheimer's disease is increasing, boosting the demand for effective symptomatic treatments like donepezil.
