DIPHENYLCYCLOPROPENONE Chemical Properties,Usage,Production

Description

Diphencyprone (DCP) is a contact sensitizing agent. Pretreatment with DCP reduces symptom severity in a mouse model of experimental autoimmune encephalomyelitis (EAE) induced by myelin basic protein (1-10) (MBP_1-10). It enhances IL-10 production and antigen-specific IgG2a antibody responses and reduces anaphylaxis and asthma induced by ovalbumin in mice when administered during ovalbumin immunization at a concentration of 1% v/v. Topical administration of DCP increases intrafollicular CD4⁺ and CD8⁺ T cells, reduces upper dermal inflammation, and stimulates hair growth in the C3H/HeJ mouse model of alopecia areta. Formulations containing DCP have been used in the treatment of alopecia areta.

Description

Diphencyprone is a potent contact allergen responsible for occupational contact dermatitis in chemists and dermatological staff.

Chemical Properties

slightly pinkish-orange to beige crystalline

Uses

Diphenylcyclopropenone was used in topical immunotherapy.

Definition

ChEBI: A cyclopropenone compound having phenyl substituents at the 2- and 3-positions.

General Description

Diphenylcyclopropenone is a potent hapten. Its vibration frequency has been evaluated.

Contact allergens

Diphencyprone is a potent contact allergen used in topical immunotherapy to treat some severe alopecia areata. It is responsible for occupational contact dermatitis in chemists and dermatology department staff

Purification Methods

Crystallise it from cyclohexane. UV (MeCN): max 226, 282, 297nm. [Beilstein 17 IV 1736.]
