and characterised by HPLC comparison with the Re–L analog. The synthesized compounds were evaluated for their anti-inflammatory and cytotoxic properties. The compounds exhibited low anti-inflammatory activity with Pd–L showing the highest activity among them. The cytotoxic activity of the ligand and the complexes against several human cancer cell lines (cervical adenocarcinoma HeLa, colorectal adenocarcinoma
合成了一种新的含噻唑多齿配体 2-((2-苯基噻唑-4-基)甲硫基)乙胺 L,并用于制备新的复合物,分子式为 Pd II LCl 2 (Pd-L) Cu II L 2 Cl 2 (Cu–L) 和fac -[Re/ 99m Tc I (CO) 3 (L)] + (Re/ 99m Tc–L)。配体 L 和金属配合物通过光谱进行表征。此外,通过 X 射线晶体学阐明了 Re-L 和 Cu-L 的结构。配体 L 在 Pd-L 中充当二齿 (N th , S) 螯合剂,在 Cu-L 中充当二齿 (N, S) 螯合剂和三齿 (N th, S, N) Re-L 中的螯合剂。放射性示踪剂99mTc-L 以高产率合成,并通过 HPLC 与 Re-L 类似物的比较来表征。评估了合成的化合物的抗炎和细胞毒性特性。这些化合物表现出低抗炎活性,其中 Pd-L 表现出最高的活性。检测了配体和复合物对几种人类癌细胞系(宫颈腺癌
