  手性组合制剂和独特的神经酰胺抑制鞘磷脂合成酶的生物学评估。

  摘要：

  手性生物活性化合物的对映异构体或非对映异构体通常表现出不同的生物学和毒理学性质。在这里，我们报告了鞘氨醇的四种立体异构体的有效合成，以及通过固相活化树脂酯的组合化学，将独特的手性神经酰胺衍生化。此外，为了测试神经酰胺的立体化学的有效性，我们证明了在手性独特神经酰胺存在下基于神经鞘磷脂合成酶抑制的细胞测定，这表明此类文库将是生物活性合成分子的丰富来源。

  Synthesis of a dihydrotestosterone–ciprofloxacin conjugate: relationship between descriptors logP, π, R m , and V m and its antibacterial activity in S. aureus and E. coli

  摘要：

  In this work a dihydrotestosterone-ciprofloxacin conjugate was synthesized. The route involved preparation of a ciprofloxacin-ethylenediamine derivative by the reaction of ciprofloxacin with ethylenediamine using a carbodiimide or boric acid as catalysts. Additionally, the ciprofloxacin derivative was bound to dihydrotestosterone hemisuccinate to form the dihydrotestosterone-ciprofloxacin conjugate in the presence of a carbodiimide. The antibacterial activity of dihydrotestosterone-ciprofloxacin, as well as ciprofloxacin-ethylenediamine and ciprofloxacin, was evaluated in vitro on S. aureus and E. coli using the dilution method and the minimum inhibitory concentration. To delineate the structural chemical requirements of the compounds ciprofloxacin, ciprofloxacin-ethylenediamine and dihydrotestosterone-ciprofloxacin conjugate as antibacterial agents on S. aureus and E. coli, other parameters such as the descriptors logP, pi, R-m, and V-m were calculated. The results showed that bacterial growth of the microorganisms studied was inhibited by ciprofloxacin, ciprofloxacin-ethylenediamine and dihydrotestosterone-ciprofloxacin in a dose-dependent manner. These data suggest that functional groups involved in the structure of the studied compounds are specific for their antibacterial activity.

  We report the first solid phase synthesis of a xanthone library CX and its application to embryonic stem cell probe development. The CX library was further derivatised with an activated ester resin to provide an acetylated CX (CXAC) library. Screening of these libraries led to the discovery of a novel fluorescent mESC probe, CDb8.
