Belinostat (PXD101), a new histone deacetylase inhibitor, has shown good performance in various cancer treatments and has been approved by the FDA for the treatment of recurrent or refractory peripheral T-cell lymphoma (PTCL) in patients with drugs. PXD101 is considered to have certain anti-allergic and anti-inflammatory properties, but its beneficial effects in UVB-induced skin photoaging have not been reported. In a recent study, HacaT cells and C57BL6 mice were used to study the impact of PXD101 on UVB-induced cellular senescence and skin photoaging and to explore their potential mechanisms of action. Studies have shown that PXD101 inhibits UVB-induced HacaT cell senescence, which appears to be achieved by inhibiting activation of the UVB-induced NF-κB/p65 signaling pathway. At the same time, PXD101 inhibits the expression of MMPs. In addition, PXD101 alleviated skin damage on the dorsal skin of mice, reduced skin aging and inflammation, increased collagen fiber synthesis, and restored UVB-induced epidermal thickening. In short, we believe that PXD101 effectively inhibits cellular senescence and skin photoaging caused by UVB exposure, a potential method for developing clinical prevention and treatment of skin aging.
