solubility was increased by three orders of magnitude, from 1.2 µg/mL (1-thieno[2,3-b]pyridine) to 1.3 mg/mL (3-pyrrolo[2,3-b]pyridine), however, it was only marginally active against cancer cells. The second strategy involved loading a very potent thieno[2,3-b]pyridine derivative (2) into a cholesteryl-poly(allylamine) polymer matrix for water solubilisation.

现在已经确定,噻吩并[2,3-b]吡啶是一种有效的抗增殖剂。其临床应用遇到的主要问题之一是其低水溶性。为了改善这一点,采用了两种策略。首先,通过用硫取代硫原子将吗啉部分束缚在分子支架上,从而得到1H-吡咯并[2,3-b]吡啶核结构。水溶性增加了三个数量级,从1.2 µg / mL(1-噻吩并[2,3-b]吡啶)增加到1.3 mg / mL(3-吡咯并[2,3-b]吡啶)。它仅对癌细胞具有微弱的活性。第二种策略涉及将非常有效的噻吩并[2,3-b]吡啶衍生物(2)装入胆甾醇基聚(烯丙胺)聚合物基质中以进行水溶解。
