this study, Ru(II)-arene complexes with acylthiourea ligands of the type [Ru(η6‑p‑cymene)(PPh3)(T)Cl]PF6(1-5) and [Ru(η6‑p‑cymene)(PPh3)(T)]PF6(1a, 4a), where PPh3 = triphenylphosphine and T = N‑acyl‑N'(monosubstituted)thiourea, were synthesized and characterized, and their cytotoxic properties were also evaluated. 1a and 4a were obtained from the hydrolysis reaction of 1 and 4. All complexes showed
在这项研究中,Ru(II)-芳烃与[Ru(η6-对-cymene)(PPh3)(T)Cl] PF6(1-5)和[Ru(η6-对-cymene)类型的酰基硫脲配体合成并表征了(PPh3)(T)] PF6(1a,4a),其中PPh3 =三苯基膦,T = N-酰基-N'(单取代)硫脲,并评估了它们的细胞毒性。1a和4a是通过1和4的水解反应获得的。所有配合物均显示出不同寻常的酰基硫脲配体配位模式,它们在1-5中以单齿方式(S)进行配位,而发现它们是二齿的(S,N)。 ,在1a和4a中。据我们所知,第一个晶体学上报道的钌化合物是带有S和N(酰胺)原子配位的酰基硫脲的钌化合物。评估了化合物在人肺细胞A549和MRC-5中的细胞毒性。IC50值范围从0.25到0。在肺癌细胞中孵育48小时后,其浓度为61μM,表明该化合物显示出高细胞毒性,其值明显低于参考药物顺铂(11.84μM)。使用人血清白蛋白(H
