Pro-inflammatory cytokines play a critical role in the development of autoimmune and
inflammatory diseases. Targeting the cytokine environment has proven efficient for averting
inflammation. In this study, we reported that 6-(4-(aminomethyl)-2-
chlorophenoxyl)benzo[c][1,2]oxaborol-1(3H)-ol (AN3485), a benzoxaborole analog, inhibited
TLR2-, TLR3-, TLR4- and TLR5-mediated TNF-α, IL-1β and IL-6 release from human PBMCs
and isolated monocytes with IC50s ranging from 18 to 580 nM, and the inhibition was mediated
at the transcriptional level. Topical administration of AN3485 significantly reduced PMAinduced contact dermatitis and oxazolone-induced delayed-type hypersensitivity in mice,
indicating its capability of penetrating skin and potential topical application in skin
inflammation. Oral administration of AN3485 showed dose-dependent suppression of LPSinduced TNF-α and IL-6 production in mice with an ED90 of 30 mg/kg. Oral AN3485, 35
mg/kg, twice a day, suppressed…
