of this study was to develop more potent analogs based upon CPZ pharmacophore and structure–activityrelationships (SAR) across analogs. We generated 30 novel compounds and screened for their anti-proliferative effects in cultured HeLa cervical cancer cells. Cell viability assays identified multiple compounds with IC50s < 15 μM and one compound, 29 with an IC50 < 5 μM; six fold more potent than CPZ
我们先前证明,辣椒素(CPZ)是一种合成的瞬时受体潜在香草酸亚型1(TRPV1)拮抗剂,在体内具有显着的抗癌作用。这项研究的目的是基于CPZ药效团和类似物之间的结构-活性关系(SAR),开发出更有效的类似物。我们生成了30种新型化合物,并筛选了它们在培养的HeLa宫颈癌细胞中的抗增殖作用。细胞活力分析鉴定出多种IC 50s <15μM的化合物和一种化合物29 IC 50 <5μM的化合物;比CPZ强六倍。我们验证两个引线化合物的抗增殖功效17和29,在体内在无胸腺裸鼠中使用HeLa衍生的异种移植物。与对照处理的动物相比,两种类似物到第8天都显着减少了肿瘤体积(p <0.001),没有明显的不良反应。钙成像确定化合物17激活TRPV1,而化合物29既不激活也不抑制TRPV1。表示不涉及TRPV1信号的唯一作用机制。使用一组其他肿瘤类型的细胞生存力分析,包括口腔鳞状细胞癌,非小细胞肺癌(N

The present invention includes novel aminothiazole compounds useful in preventing or treating cancer in a subject in need thereof. The present invention also includes methods of preventing or treating cancer in a subject in need thereof by administering to the subject a therapeutically effective amount of a compound of the invention.
The role of 5-arylalkylamino- and 5-piperazino- moieties on the 7-aminopyrazolo[4,3-<i>d</i>]pyrimidine core in affecting adenosine A<sub>1</sub> and A<sub>2A</sub> receptor affinity and selectivity profiles
New 7-amino-2-phenylpyrazolo[4,3-d]pyrimidine derivatives, substituted at the 5-position with aryl(alkyl)amino- and 4-substituted-piperazin-1-yl- moieties, were synthesized with the aim of targeting human (h) adenosine A1 and/or A2A receptor subtypes. On the whole, the novel derivatives 1-24 shared scarce or no affinities for the off-target hA2B and hA3 ARs. The 5-(4-hydroxyphenethylamino)- derivative

A copper-catalyzed tandem arylation–cyclization process to access 1-(arylthio)isoquinolines from isothiocyanates and diaryliodonium salts is described. It is the first general method to construct the potentially useful 1-(arylthio)isoquinoline derivatives. Moreover, 1-(methylthio)isoquinoline derivatives were also achieved successfully with MeOTf instead of diaryliodonium salts under metal-free conditions
