Methylthiouracil is a thiourea-class antithyroid agent that inhibits the synthesis of thyroid hormones and is commonly used to treat hyperthyroidism. Studies have shown that Methylthiouracil can also suppress the production of TNF-α and IL-6, as well as inhibit the activation of NF-κB and ERK1/2. It can be used to induce hyperlipidemia and neurological disorder models.

Triamcinolone (Aristocort) is a synthetic glucocorticoid with anti-inflammatory and immunomodulating properties. Upon cell entry, triamcinolone binds to and activates the glucocorticoid receptor, which leads to translocation of the ligand-receptor complex to the nucleus and induces expression of glucocorticoid-responsive genes such as lipocortins. Lipocortins inhibit phospholipase A2, thereby blocking the release of arachidonic acid from membrane phospholipids and preventing the synthesis of prostaglandins and leukotrienes, both mediators of inflammation. In addition, pro-inflammatory cytokine production, including interleukin (IL)-1and IL-6, and the activation of cytotoxic T-lymphocytes is also inhibited. T-cells are prevented from making IL-2 and proliferating. This agent also decreases the number of circulating lymphocytes, induces cell differentiation, and stimulates apoptosis through increasing Ikappa-B expression and curtailing activation of nuclear factor (NF)kappa-B.

Topically applied at 0.1%, PQA-18 reduces the severity of atopic dermatitis, serum IgE levels, and skin thickness in the NC Nga mouse model. A lower concentration of 0.05% also decreases skin nerve fiber density in NC Nga mice. Additionally, PQA-18 administered at 4 mg kg improves graft survival in a rat small intestine transplantation model.
