Abstract

L. (AngTE) and L. (AnsTE) fruits have been widely used in cancer treatment. Accordingly, their extracts were used to synthesize silver nanoparticles via a biogenic route (Ang-AgNPs) and (Ans-AgNPs), respectively. Chemical profiling was established using UPLC-QTOF-MS/MS. All species were tested for anticancer activity against human cervical cancer cells (HeLa), prostate adenocarcinoma metastatic (PC3), and ovary adenocarcinoma (SKOV3) using sulphorhodamine B assay. Apoptosis was determined using Annexin flow cytometry along with cell cycle analysis and supported by a molecular docking. The antibacterial and synergistic effect when combined with gentamicin were evaluated. A total of 114 compounds were tentatively identified, mainly acetogenins and -kaurane diterpenes. AnsTE and Ans-AgNPs had the most potent cytotoxicity on HeLa and SKOV3 cells, inducing a significant apoptotic effect against all tumor cells. The AnsTE and Ans-AgNPs significantly arrested PC3, SKOV3, and HeLa cells in the S phase. The nanoparticles demonstrated greater antibacterial and antifungal activities, as well as a synergistic effect with gentamicin against and . Finally, a molecular docking was attempted to investigate the binding mode of the identified compounds in Bcl-2 proteins' receptor, implying that the fruits and their nanoparticles are excellent candidates for treating skin infections in patients with ovarian or prostatic cancer.

摘要

L. (AngTE) 和 L. (AnsTE) 的果实已被广泛用于癌症治疗。因此,它们的提取物分别通过生物途径用于合成银纳米颗粒(Ang-AgNPs)和(Ans-AgNPs)。使用超高效液相色谱-四极杆飞行时间串联质谱(UPLC-QTOF-MS/MS)建立化学图谱。使用磺酰罗丹明 B 测定法对所有物种针对人宫颈癌细胞(HeLa)、前列腺腺癌转移细胞(PC3)和卵巢腺癌(SKOV3)进行抗癌活性测试。使用膜联蛋白流式细胞术结合细胞周期分析确定细胞凋亡,并通过分子对接得到支持。评估了与庆大霉素联合使用时的抗菌和协同作用。初步鉴定出总共 114 种化合物,主要是产乙酸素和 -贝壳杉烷二萜。AnsTE 和 Ans-AgNPs 对 HeLa 和 SKOV3 细胞具有最强的细胞毒性,对所有肿瘤细胞均诱导出显著的凋亡作用。AnsTE 和 Ans-AgNPs 使 PC3、SKOV3 和 HeLa 细胞在 S 期显著停滞。纳米颗粒表现出更强的抗菌和抗真菌活性,以及与庆大霉素对……的协同作用。最后,尝试进行分子对接以研究鉴定出的化合物在 Bcl-2 蛋白受体中的结合模式,这表明这些果实及其纳米颗粒是治疗卵巢癌或前列腺癌患者皮肤感染的极佳候选物。
