What is Acitretin API?

Acitretin API, is a drug made from vitamin A, also known as all-trans retinoic acid or betarretin A. It controls how many skin cells proliferate and differentiate while also affecting how the stratum corneum develops. It improves disorders like keratosis, lessens acne, and controls skin pigmentation by attaching to the vitamin A acid receptor in the nucleus of cells and changing gene transcription and protein expression. With a molecular weight of 326.43 g/mol and a chemical formula of C21H26O3, It often takes the form of a yellowish crystal or crystalline powder. It has the CAS number 55079-83-9. Hexane can be used to solidify it, and its melting point is 228 – 230 °C. The LD50 by intraperitoneal injection ranges from> 4000 mg/ kg( 1 day) to 700 mg/ kg( 10 days and 20 days), according to exploration on acute toxin in mice. The active metabolite of tretinoin is acitretin, a synthetic sweet counterpart of vitamin A. In addition to other skin conditions, it's used to treat severe psoriasis and keratosis.

Function & Application

Acitretin API is an oral medication belonging to the retinoid class of drugs. It is primarily used to treat various skin conditions, particularly severe psoriasis (severe plaque psoriasis), keratinization disorders, and palmoplantar keratoderma.

The following is a list of it application and functions:

• Psoriasis treatment: it reduces the itching, scaling, red spots, and joint pain associated with psoriasis. It controls cellular division and proliferation, which lessens excessive keratinization and inflammatory reaction and lessens the severity of psoriasis.

• Treatment of keratinization disorders: it can be used to treat loricrin keratoderma and non-epidermolytic palmoplantar keratoderma. The symptoms and look of the skin are improved by reducing excessive skin keratinization.

• Treatment of palmoplantar keratoderma: it can treat palmoplantar keratoderma by reducing the thickness and level of keratinization in the palms and soles, alleviating symptoms such pain, fissures, and increasing keratinization.

It may cause side effects during therapy, such as dry mouth, cheilitis, eye symptoms, and altered liver function, thus it's crucial to be aware of this. As a result, it should be used under the supervision of a physician, with ongoing evaluation of its efficacy and safety. it is also not advised for use by women who are expecting or nursing because it could harm the fetus or newborns.

Adverse reactions

Dry lips, cheilitis, angular stomatitis, dry or irritated oral mucosa, and transitional epithelium are signs of high vitamin A levels. Intolerance to contact lenses, keratitis, corneal ulceration, and conjunctivitis. signs of intestinal inflammation. a thirst and a sweat. hair loss that is reversible. skin that is thinner and scaly. Paronychia, unusual nail growth, granuloma, and occasional skeletal, joint, and muscular pain. decreased high-density lipoprotein, increased triglycerides and cholesterol, elevated transaminases and alkaline phosphatase. Increased intracranial pressure symptoms include headache, blurred vision, excessive calcification, extraosseous calcification, osteoporosis, and early epiphyseal plate closure.

Production method

4-methoxy-2,3,6-trimethylbenzaldehyde (Ⅰ) and ethyl formate react in phosphoric acid-containing ethanol to yield compound (Ⅱ) with a yield of 84%. Then, it reacts with (Ⅲ) in ethyl acetate containing zinc chloride to yield a mixture of 6:4 (E)-(Ⅳ) and (Z)-(Ⅳ), with a total yield of 83%. Acid elimination gives 27% of (E,E)-(V) and 21% of (Z,E)-(V). (E,E)-(V) reacts with acetone in a methanol-water solution to yield 25% of compound (Ⅵ). It reacts with ethoxyethynylmagnesium bromide Grignard reagent in ether to yield compound (Ⅶ) with a yield of 48%. Finally, hydrolysis yields a 91% product.

Stability & storage

It is a derivative of vitamin A acid. Its stability and storage conditions are as follows:

Stability: It can be relatively stable for a long time when stored in dry, light-protected, and sealed conditions. However, it is sensitive to light and can easily degrade and lose effectiveness when exposed to light. Additionally, It is also sensitive to high temperatures and oxygen, which may reduce its stability.

Storage conditions: To ensure the stability of it, the following storage conditions are recommended:

• Temperature: Store it at room temperature (15°C - 30°C).

• Humidity: Maintain a relatively low humidity level and avoid humid environments.

• Light: Place it in light-protected containers to prevent direct exposure to light.

• Packaging: Use sealed containers or packaging materials to ensure proper sealing.
