mouse liver microsomes, compounds 29 and 38 were evaluated in vivo and found to have good oral bioavailability (56% and 101%, respectively) in mice. X–ray co–crystal structure of compound 27 in RORγt revealed that the bulky benzyl ether group causes helix 11 of the protein to partially uncoil to create a new, enlarged binding site, which nicely accommodates the benzyl ether moiety, leading to net potency
在努力发现的ROR口服反向激动剂γ吨治疗炎症性疾病中,发现了新的2,6-二氟苄醚系列环戊基砜的比相应的醇衍生物出人意料地更有效。当与更优化的苯基((组合[R)-3-苯基吡咯烷-3-基)砜模板时,2,6-二氟苄醚,得到一组非常有效的ROR γ吨反向激动剂(例如,化合物26,ROR γ吨Gal4 EC 50 11 nM),对PXR,LXRα和LXRβ具有高度选择性。在优化人和小鼠肝微粒体的稳定性后,对体内化合物29和38进行了评估并且在小鼠中具有良好的口服生物利用度(分别为56%和101%)。化合物的X-射线共晶体结构27在ROR γ吨显示,该笨重的苄基醚基使蛋白质的螺旋11,以部分地开卷以创建新的,扩大的结合位点,这很好地容纳苄醚部分,导致净效能提升。
