A series of thin-film n-channelorganic field-effect transistors based on various birhodanines, 3,3′-dialkyl-5,5′-bithiazolidinylidene-2,2′-dione-4,4′-dithiones (OS-R) and their sulfur analogues, 3,3′-dialkyl-5,5′-bithiazolidinylidene-2,4,2′,4′-tetrathiones (SS-R) are studied. The SS-R compounds have tilted stacking crystal structures, whereas the OS-R compounds show basically herringbone structures

The biological properties of sixteen structurally related monoanionic gold (III) bis(dithiolene/diselenolene) complexes were evaluated. The complexes differ in the nature of the heteroatom connected to the gold atom (AuS for dithiolene, AuSe for diselenolene), the substituent on the nitrogen atom of the thiazoline ring (Me, Et, Pr, iPr and Bu), the nature of the exocyclic atom or group of atoms (O
评估了 16 种结构相关的单阴离子金 (III) 双(二硫烯/二硒烯) 配合物的生物学特性。这些配合物的不同之处在于与金原子相连的杂原子(AuS 代表二硫烯,AuSe 代表二硒烯)、噻唑啉环氮原子上的取代基(Me、Et、Pr、iPr 和 Bu)、环外原子或原子团(O、S、Se、C(CN) 2)和反离子(Ph 4 P +或 Et 4 N +)。研究了所有复合物的抗癌和抗菌活性,而仅评估了选定复合物的抗 HIV 活性。大多数复合物分别对顺铂敏感和顺铂耐药的卵巢癌细胞 A2780 和 OVCAR8 显示出相关的抗癌活性。孵育 48 小时后,IC 50值范围为 0.1–8 µM (A2780) 和 0.8–29 µM (OVCAR8)。与 Ph 4 P + ([ P ]) 抗衡离子的配合物通常比 Et 4 N + ([ N ]) 类似物更活跃,IC 50值在相同数量级甚至低于金诺芬。斑马鱼胚胎模型
