with carbondisulfide in the presence of bases. These compounds were tested for the inhibition of four human (h) isoforms of the zinc enzyme carbonic anhydrase, CA (EC 4.2.1.1), hCA I, II, IX, and XII, involved in pathologies such as glaucoma (CA II and XII) or cancer (CA IX). Several low nanomolar inhibitors targeting these CAs were detected. The X-ray crystalstructure of the hCA II adduct with morpholine
在碱存在下,伯胺/仲胺与二硫化碳反应制备了一系列二硫代氨基甲酸酯。测试了这些化合物对锌酶碳酸酐酶 CA (EC 4.2.1.1)、hCA I、II、IX 和 XII 的四种人类 (h) 亚型的抑制作用,这些亚型涉及青光眼(CA II 和 XII)等病理学) 或癌症 (CA IX)。检测到几种针对这些 CA 的低纳摩尔抑制剂。hCA II 与吗啉二硫代氨基甲酸酯的 X 射线晶体结构证明了这些化合物的抑制机制,它们通过二硫代氨基甲酸酯锌结合功能的硫原子与金属离子配位。一些二硫代氨基甲酸盐在葡糖眼动物模型中显示出有效的降低眼内压的活性。

A carbonic anhydrase inhibitor which comprises a compound of general formula: R1R2N-CS2-M+ for use in the treatment of microbial infection, eye disease or cancer; wherein R1 and R2 are each independently selected from H or an organic substituent, or together form a ring, and optionally contain one or more heteroatoms; wherein R and R2 together comprise at least 5 carbon atoms or at least 2 carbon atoms and a heteroatom, or R2 comprises at least 4 carbon atoms; and wherein M+ comprises a monovalent cation.
elemental analysis, molar conductivity measurements, FT-IR, 1H NMR, 13C NMR and electronic spectra studies. The anticanceractivityagainst HeLa celllines demonstrated lower cytotoxicity than cisplatin. The binding constants and the thermodynamic parameters were determined at different temperatures (300 K, 310 K and 320 K) and shown that the complex can bind to DNA via electrostatic forces.

摘要 新型水溶性钯 (II) 络合物 [Pd(bpy)(bez-dtc)]Cl(其中 bpy 是 2,2'-联吡啶,bez-dtc 是二硫代氨基甲酸苄酯)作为抗肿瘤剂的结合能力和小牛胸腺 DNA 使用各种物理化学方法进行评估,例如 UV-Vis 吸收、竞争性荧光研究、粘度测量、zeta 电位和圆二色性 (CD) 光谱。使用元素分析、摩尔电导率测量、FT-IR、1H NMR、13C NMR 和电子光谱研究合成并表征了 Pd(II) 配合物。对 HeLa 细胞系的抗癌活性显示出比顺铂更低的细胞毒性。结合常数和热力学参数在不同温度(300 K、310 K 和 320 K)下测定,结果表明复合物可以通过静电力与 DNA 结合。此外,该结果通过粘度和 zeta 电位测量得到证实。CD 光谱结果表明 Pd(II) 复合物与 DNA 的结合诱导了 DNA 的构象变化。我们希望这些结果能为抗癌药物的进一步研究和临床实际应用提供依据。
4‐Aryl‐2‐Imino‐1,3‐Dithiolanes from the Room Temperature Coupling of Sodium Dithiocarbamates with Sulfonium Salts
A new and easy synthesis of 4‐aryl‐2‐imino‐1,3‐dithiolanes was performed in water/dichloromethane starting from simple precursors, i. e., dithiocarbamate and sulfonium bromide salts. Various possible mechanism pathways were investigated by DFT calculations.
