hallmark of human cancer. Ceramide analogues thereby represent a new class of anti-cancer agents. We aimed at developing effective and low toxic ceramide analogues and synthesized a new class of ceramide analogues starting from l-threonine. Several analogues exhibit potent cytotoxicity against human cancer cells in vitro with IC50 as low as 4.8 μM. These ceramide analogues decreased xIAP and Bcl-xL level
神经酰胺代谢失调是人类癌症的标志。因此,神经酰胺类似物代表了一类新的抗癌药。我们旨在开发有效且低毒的神经酰胺类似物,并从l-苏氨酸开始合成了一类新的神经酰胺类似物。几种类似物在体外对人癌细胞表现出强大的细胞毒性,IC50低至4.8μM。这些神经酰胺类似物降低了xIAP和Bcl-xL的水平,并表现出显着的敏化活性,可以克服人类癌细胞对TRAIL的抗性,TRAIL是在人类临床试验中测试的一种癌症选择剂。此外,我们确定这些神经酰胺类似物可有效抑制体内人类癌症异种移植物的生长,并且在有效剂量下无明显毒性。所以,
