Psoriasis is a chronic inflammatory autoimmune skin disorder, generally due to the interaction between genetic, environmental and immune factors. It is mainly associated with HLA locus (HLA-C), particularly with HLA-Cw* 0602 allele. The stimulation of T-cell induces hyper-proliferation of keratinocytes, which results in psoriatic lesions. Psoriatic patients are usually treated with medications that block TNF-α function. Complexities in the pathogenesis of psoriasis have been a challenge to develop an effective treatment regimen. Thus, studies are still underway for exploring drugs to treat psoriasis. Researchers have reported the antioxidant, antibacterial and anti-inflammatory properties of the structural half analogue of curcumin, dehydrozingerone (DHZ). Pre-clinical studies have reported the wound healing and anti-inflammatory properties of this compound. DHZ is also capable of blocking TNF alpha, which is one of the early cytokines implicated in psoriasis. Therefore, the current study has been proposed to explore the effect of DHZ to reduce psoriatic like lesions in imiquimod-induced psoriasis in mice. Upon the development of psoriatic like lesions, clinical scoring for scaling and erythema was taken on a scale of 0-4. DHZ has shown a significant reduction of scaling in comparison to the disease control, denoting the effectiveness of the test drug.
