About Dapsone

Dapsone is an antibiotic medication which is used to treat skin disorders such as dermatitis herpetiformis, a chronic condition in which bumps and blisters occur on the skin. This medication has the approval of the United States Food and Drug Administration (FDA) and was first used for the treatment of leprosy in 1945. It is available in both oral and topical formulations and can also be used for other dermatological purposes.

Properties of Dapsone

Dapsone is a type of small molecule which possesses an average molecular weight of 248.301. Its colour ranges from white to slightly yellowish white and it has a slightly bitter taste. This compound has a melting point of 175.5 °C, water solubility of 380 mg/L at 37 °C and a terminal half-life of 28 hours. Dapsone exhibits bacteriostatic properties which makes it viable for the treatment of Mycobacterium leprae at 1 to 10 mg/L.

Manufacturing Process of Dapsone

The one-pot method is used for the preparation of dapsone. In this method, firstly nitrobenzene sulfonyl chloride is taken as a raw material and mixed with methanol (solvent) for the desulphurisation reaction, which removes sulphur from the compound. This reaction is performed under copper acetate to obtain the intermediate compound, para-dinitrophenyl sulfone. In the last step, sodium hydrosulphite is added to the intermediate compound in the reaction system to produce dapsone, which is then purified for usage in the industrial sector.

Synthesis of Dapsone

Dapsone (4,4'-diaminodiphenylsulfone) is an antibiotic commonly used in the treatment of leprosy and dermatitis herpetiformis. Its synthesis involves several key steps primarily centred around the formation of the sulfone group in a diphenyl derivative. Below are the primary steps:

1. Synthesis of 4-nitrochlorobenzene:

Reactants: Chlorobenzene (C6H5Cl)

Reaction: C6H5Cl + HNO3 → 4-Nitrochlorobenzene (C6H4ClNO2) + H2O

Conditions: Nitration using nitric acid.

2. Reduction to 4-chloroaniline:

Reactants: 4-Nitrochlorobenzene (C6H4ClNO2)

Reaction: C6H4ClNO2 + 3 H2 → 4-Chloroaniline (C6H6ClN) + 2 H2O

Conditions: Catalytic hydrogenation.

3. Diazotization of 4-chloroaniline:

Reactants: 4-Chloroaniline (C6H6ClN)

Reaction: C6H6ClN + HNO2 → Diazonium Salt (C6H5ClN2⁺) + 2 H2O

Conditions: Reaction with nitrous acid at cold temperatures.

4. Coupling of Diazonium Salt with Sulfanilic Acid:

Reactants: Diazonium Salt (C6H5ClN₂⁺) and Sulfanilic Acid (C6H7NO3S)

Reaction: C6H5ClN2⁺ + C6H7NO3S → Dapsone (C12H12N2O2S) + HCl

Conditions: Aqueous coupling under basic conditions.

5. Final Reaction:

2(C6H5Cl) + 2HNO3 + 6H2 + HNO2 + C6H7NO3S → Dapsone (C12H12N2O2S) + 3H2O + HCl

This process showcases the integration of several organic synthesis techniques to achieve the final medicinal product.

Applications and Drivers of Dapsone

Dapsone is an antibiotic agent which was initially used for leprosy treatment due to its bacteriostatic properties. Nowadays, it is commonly used for the treatment of dermatitis herpetiformis and in combination with other drugs for the treatment of Hansen's disease. This medication can inhibit the growth of bacteria and decrease swelling in the human body which makes it effective for the treatment of skin conditions. As per industry reports, around 25% of the people in the world who are affected by celiac disease, suffer from dermatitis herpetiformis, which has fuelled the demand for dapsone.
