Amaryllidaceae plants are rich in alkaloids with biological properties. is an Amaryllidaceae species widely used in African folk medicine to treat several diseases such as central nervous system disorders, tumors, and microbial infections, and it is used to heal wounds. The current investigation explored the biological properties of alkaloid extracts from bulbs of collected in the Senegalese flora. Alkaloid extracts were analyzed and identified by chromatography and mass spectrometry. Alkaloid extracts from displayed pleiotropic biological properties. Cytotoxic activity of the extracts was determined on hepatocarcinoma Huh7 cells and on acute monocytic leukemia THP-1 cells, while agar diffusion and microdilution assays were used to evaluate antibacterial activity. Antiviral activity was measured by infection of extract-treated cells with dengue virus (DENV) and human immunodeficiency virus-1 (HIV-1) reporter vectors. Cytotoxicity and viral inhibition were the most striking of 's extract activities. Importantly, non-cytotoxic concentrations were highly effective in completely preventing DENV replication and in reducing pseudotyped HIV-1 infection levels. Our results show that is a rich source of molecules for the potential discovery of new treatments against various diseases. Herein, we provide scientific evidence to rationalize the traditional uses of for wound treatment as an anti-dermatosis and antiseptic agent.
石蒜科植物富含具有生物活性的生物碱。 是石蒜科的一个物种,广泛用于非洲民间医学,用于治疗中枢神经系统疾病、肿瘤和微生物感染等多种疾病,并用于治疗伤口。本研究探讨了从塞内加尔植物区系中收集的 鳞茎中的生物碱提取物的生物学特性。通过色谱和质谱分析鉴定生物碱提取物。 从 中提取的生物碱表现出多种生物学特性。提取物的细胞毒性活性在肝癌 Huh7 细胞和急性单核细胞白血病 THP-1 细胞上进行测定,同时使用琼脂扩散和微量稀释测定法评估抗菌活性。通过用登革热病毒 (DENV) 和人类免疫缺陷病毒-1 (HIV-1) 报告载体感染经提取物处理的细胞来测量抗病毒活性。细胞毒性和病毒抑制是 的提取物活性中最显著的。重要的是,非细胞毒性浓度可有效完全抑制 DENV 复制并降低假型 HIV-1 感染水平。我们的研究结果表明, 是具有多种生物活性分子的丰富来源,可用于发现针对各种疾病的新疗法。在此,我们提供科学证据来合理说明 作为皮肤病治疗和防腐剂的传统用途。
