  用新型白花丹素衍生物治疗胰腺癌：设计、合成、分子机制、体外和体内评价

  摘要：

  胰腺肿瘤生长在以营养匮乏和缺氧为特征的“严峻”肿瘤微环境中。这导致胰腺癌细胞中适应性途径的激活，促进对营养饥饿和侵袭性恶性肿瘤的耐受性。传统的抗癌药物通常对在这种严峻条件下生长的肿瘤无效。白花丹素是一种植物来源的萘醌，在营养缺乏的条件下对胰腺癌细胞表现出强大的优先细胞毒性。因此，我们合成了一系列白花丹素衍生物，发现2-(环己基甲基)-白花丹素( 3f )是最有前途的化合物，其PC 50值为0.11 μM。从机制上讲， 3f可抑制 PI3K/Akt/mTOR 信号通路，导致营养缺乏条件下癌细胞死亡。使用胰腺癌异种移植小鼠模型的体内研究证实了3f的功效，证明以剂量依赖性方式显着抑制肿瘤生长。化合物3f代表了基于反紧缩策略的抗癌药物开发的一种非常有前景的先导药物。

  A microwave-assisted solid-supported Dötz benzannulation of chromium carbene complexes with various alkynes has been developed. The oxidative cleavage of the resulting resin-bound 1,4-naphthols affords 2,3-disubstituted-1,4-naphthoquinone derivatives in good to moderate yields with high purities.

  in solvent or substituents on the acetylene. The reactions of aryl complexes with acetylenes are quite sensitive to the nature of the solvent and the acetylene. The highest selectivities and efficiencies for the benzannulated product from the reactions of aryl complexes are with solvents of low coordinating ability. Solvents with intermediate coordinating ability and small size give high selectivity

• Substrate regulation of product distribution in the reactions of arylchromium carbene complexes with alkynes

  The reactions of arylcarbene complexes with alkynes were examined for six of the nine possible substitution patterns for mono- and dioxygenated aryl substituents of the carbene carbon. The product distributions were found to be highly dependent on a number of factors, including solvent, temperature, concentration of alkyne, and the nature of the aryl substituent. The product distributions were determined in nearly all cases for phenol and indene products and in some cases for furans, cyclobutenones, and cyclopentenediones, which were minor products in these reactions. The product distribution for the reaction of each arylcarbene complex was determined as a function of both temperature and alkyne concentration, since the combined product distribution profiles provided a much more sensitive measure of the relative influences of the aryl substituents on the reaction outcome. Furthermore, this distribution profile was determined for the reactions with 3-hexyne and I-pentyne for each carbene complex. A series of monosubstituted arylcarbene complexes were examined to identify the effects of oxygen substituents at various positions on the aryl ring. The m-methoxy group has no effect on the product distribution, whereas the o-methoxy group influences the distribution by its ability to chelate to the metal center and the p-methoxy group influences the distribution by its ability to donate electrons by resonance. The product distributions from the reactions of the 2,3-, 2,4-, and 2,5-dimethoxy complexes followed the profile expected from the simple sum of the profiles of the monomethoxyl complexes. In all cases where an effect was observed, higher concentrations of alkyne led to a higher selectivity for phenol over indene products. The dependence of the product distribution on the concentration of the alkyne substrate is suggested to be due to a process in which a second molecule of alkyne coordinates to the metal center and determines the chemical outcome of an intermediate that has covalently incorporated the first alkyne. It is further suggested that the special ability of an alkyne to display this effect is related to the ability of an alkyne to readily switch from a 2 to a 4 e- donor. This phenomenon of substrate regulation of product distribution is termed the allochemical effect, and a mechanistic explanation is developed that features this proposed process and that is refined to accommodate the observed effects of solvent, temperature, chelation, and steric and electronic effects that have been observed for the reaction of carbene complexes and alkynes.

  The chromium carbene Dotz annulation reaction proceeds very rapidly in the presence of ultrasound giving good yields of quinone product on oxidative workup. Moreover, the yield of annulated product has been improved by adsorbing the reagents onto silica and heating at moderate temperatures. Both these modifications have proved to be successful for a variety of complexes and alkynes.
