磷脂酰肌醇3-激酶α(PI3Kα)是细胞内信号通路的重要调节剂,可控制多种多样的生理过程。由于PI3K途径在人类癌症中经常被上调,因此PI3Kα的抑制可能是一种有前途的癌症治疗方法。在本研究中,我们通过片段增长策略设计并合成了一系列新的咪唑并[1,2- a ]吡啶衍生物作为PI3Kα抑制剂。通过改变咪唑[1,2- a]的3和6位上的基团]吡啶,我们研究了结构活性关系(SAR)谱,并鉴定了一系列有效的PI3Kα抑制剂。代表性衍生物在细胞增殖和凋亡测定中显示出良好的活性。而且,这些抑制剂表现出值得注意的抗血管生成活性。

The invention described herein comprises compounds of formula (IV) and a method of treating cancer comprising administering to a subject having cancer one of the compounds in conjunction with another therapeutic treatment of cancer. The compounds (IV) inhibit signaling by a member of the TGF-β superfamily such as Nodal or Activin.
Disclosed are imidazole and thiazole compounds, as well as pharmaceutical compositions and methods of use thereof. One embodiment is a compound having the structure
and pharmaceutically acceptable salts, prodrugs and N-oxides thereof (and solvates and hydrates thereof), wherein X, A, Z, R
1
and R′ are as described herein. In certain embodiments, a compound disclosed herein inhibits TGF-β, and can be used to treat disease by blocking TGF-β signaling.
Described are GCF-8 inhibitors of the formula (I),
and pharmaceutically acceptable salts thereof, wherein n, R
