Cannabidiol (CBD) is a biologically active compound present in the plants of the Cannabis family, used as anticonvulsant, anti-inflammatory, anti-anxiety, and more recently, anticancer drug. In this work, its use as a new self-assembly inducer in the formation of nanoparticles is validated. The target conjugates are characterized by the presence of different anticancer drugs (namely N-desacetyl thiocolchicine, podophyllotoxin, and paclitaxel) connected to CBD through a linker able to improve drug release. These nanoparticles are formed via solvent displacement method, resulting in monodisperse and stable structures having hydrodynamic diameters ranging from 160 to 400 nm. Their biological activity is evaluated on three human tumor cell lines (MSTO-211H, HT-29, and HepG2), obtaining GI50 values in the low micromolar range. Further biological assays were carried out on MSTO-211H cells for the most effective NP 8B, confirming the involvement of paclitaxel in cytotoxicity and cell death mechanism
大麻二酚(CBD)是一种存在于大麻科植物中的生物活性化合物,可用作抗惊厥、抗炎、抗焦虑药物,最近还被用作抗癌药物。在这项研究中,我们验证了它在纳米颗粒形成过程中作为一种新的自组装诱导剂的用途。目标共轭物的特点是不同的抗癌药物(即 N-去乙酰硫代小檗碱、荚膜多酚和紫杉醇)通过一种能够改善药物释放的连接剂与 CBD 连接。这些纳米粒子是通过溶剂置换法形成的,具有单分散和稳定的结构,其水动力直径在 160 纳米到 400 纳米之间。在三种人类肿瘤细胞系(MSTO-211H、HT-29 和 HepG2)上对它们的生物活性进行了评估,得到的 GI50 值在较低的微摩尔范围内。针对最有效的 NP 8B 对 MSTO-211H 细胞进行了进一步的生物检测,证实紫杉醇参与了细胞毒性和细胞死亡机制。
