K145是鞘氨醇激酶2(SphK2)的选择性抑制剂,其IC50值为4.3 μM[1].
K145是一种鞘氨醇类似物,与SphK2底物竞争,体外测定Ki值为6.4 μM.相对于SphK1和CERK,K145选择性地抑制SphK2.在U937细胞中,K145降低细胞总S1P并抑制FTY720磷酸化(S1P与FTY720均为SphK2的底物).同时,K145显著抑制细胞生长并诱导晚期凋亡.在上述细胞系中,K145也能抑制ERK和Akt磷酸化[1].
在U937细胞异种移植小鼠模型中,K145抑制肿瘤生长,其TGI值为44.2%,较Tamibarotene毒性小.在JC异种移植BALB/c小鼠中,K145也能有效抑制肿瘤生长.此外,在U937细胞异种移植BALB/C-nu小鼠中,口服K145比Tamibarotene具有更好的抗肿瘤活性[1].
