  穿透细胞的动态共价苯并聚砜网络

  摘要：

  环状寡硫属化合物（COC）有望成为渗透细胞的有前途的系统。明显优于和不同于已报道的二硒代壬二烯和表二硫代二酮哌嗪，我们引入了苯并多硫烷（BPS），它们显示出有效的递送，对内吞作用抑制剂的不敏感性以及与蛋白质一样大的底物的相容性。这种高活性与选择性地对硫醇的高反应性相吻合，超过了二硫化物在张力下的交换速率。其结果是形成了一个动态的共价网络，其中包括从二聚体到七聚体的最高硫物种，包括环状低聚物，环中最多包含19个硫。然后，从这个不断发展的自适应网络中进行选择，即可获得进入新的吸收途径所需的反应性和选择性。与其他COC相反，BPS在硫醇亲和柱上显示出很高的保留率。

  Synthesis, Characterization, Mechanism of Decomposition, and Antiproliferative Activity of a Class of PEGylated Benzopolysulfanes Structurally Similar to the Natural Product Varacin

  摘要：

  Benzopolysulfanes, 4-CH3(OCH2CH2)(3)NHC(O)-C6H4-1,2-S-x (x = 3-7 and 9) were synthesized with a PEG group attached through an amide bond and examined for water solubility, antitumor activity, and propensity to equilibrate and desulfurate. LCMS and HPLC data show the PEG pentasulfane ring structure predominates, and the tri-, tetra-, hexa-, hepta-, and nonasulfanes were present at very low concentrations. The presence of the PEG group improved water solubility by 50-fold compared to the unsubstituted benzopolysulfanes, C6H4Sx (x = 3, 5, and 7), based on intrinsic solubility measurements. Polysulfur linkages in the PEG compounds decomposed in the presence of ethanethiol and hydroxide ion. The PEG pentathiepin desulfurated rapidly, and an S-3 transfer reaction was observed in the presence of norbornene; no S-2 transfer reaction was observed with 2,3-dimethylbutadiene. The antitumor activities of the PEG-substituted benzopolysulfane mixtures were analyzed against four human tumor cell lines PC3 (prostate), DU145 (prostate), MDA-MB-231 (breast), and Jurkat (T-cell leukemia). The PEG-conjugated polysulfanes had IC50 values 1.2-5.8 times lower than the parent "unsubstituted" benzopolysulfanes. Complete cell killing was observed for the PEG polysulfanes at 4 mu M for PC3 and DU145 cells and at 12 mu M for MDA-MB-231 cells. The results suggest that solubilization of the polysulfur linkage is a key parameter to the success of these compounds as drug leads.

Selection from this unfolding adaptive network then yields the reactivities and selectivities needed to access new uptake pathways. Contrary to other COCs, BPS show high retention on thiol affinity columns. The identification of new modes of cell penetration
