Two 9,10-distyrylanthracene (DSA) derivatives CNDSA and t-BUDSA were designed and synthesized, and their photophysical properties and crystal structures were investigated. Compared to DSA, the maximum emission peaks of the two compounds showed red-shift not only in THF solution, but also in crystals, because the introduction of electron-withdrawing substituents to DSA leads to more dispersion of the electrons in the molecules. The two crystals of CNDSA and t-BUDSA show strong fluores- cence with the efficiency F of 45% and 33%, respectively, which may be resulted from no obvious-interactions between molecules inside the crystal due to the large distance between the two adjacent molecules and nearly no overlap between the central anthracene planes. The analysis of crystal structures of the two compounds indicated that the molecules are arranged in the same conformation and orientation in their crystals, i.e. uniaxially oriented packing crystal, because of the supramolecular interac- tion of CH/ in the two crystals and additional C-H···N interactions in CNDSA.

乳腺癌是全世界最常见的一种女性恶性肿瘤。三阴性乳腺癌是指雌激素受体、孕激素受体和人表皮生长因子受体2的表达均为阴性的乳腺癌,约占所有乳腺癌病理类型的15%~20%。三阴性乳腺癌的预后差、复发转移率高、死亡率高,已成为近年来乳腺癌研究和关注的焦点。目前针对乳腺癌的治疗手段包括手术治疗、新辅助化疗、辅助化疗、内分泌治疗和靶向治疗等。由于三阴性乳腺癌患者缺少雌激素受体、孕激素受体和人表皮生长因子受体2的表达,因此患者无法从针对乳腺癌的内分泌治疗及抗人表皮生长因子受体2的靶向治疗中获益。化疗是目前较推荐的三阴性乳腺癌治疗方法。许多化疗方案及新型的化疗药物也正在探索之中。本文对三阴性乳腺癌的化疗、内分泌治疗、靶向治疗和免疫治疗的研究进展进行综述。
