Cancer and infectious diseases are among the leading causes of death in world. Despite diverse array treatments available, challenges posed by resistance, side effects, high costs, inaccessibility persist. In Solanaceae plant family, few studies with Vassobia breviflora species relating to biological activity known, but promising results have emerged. The phytochemicals present ethyl acetate fraction were obtained using ESI-MS-QTOF, antioxidants assays 1,1-diphenyl-2-picrylhydrazyl (DPPH),...
Cancer and bacterial infections are among the leading causes of death worldwide. Plant-derived bioactive compounds constitute promising alternatives for development new therapeutics. This study aimed at evaluating biological activity Withaferin A using 6 tumor cell lines: A549 (lung cancer), U87MG (glioblastoma), SH-SY5Y (neuroblastoma), B16-F10 (mouse melanoma), HeLa (uterine colon cancer) K562 (chronic myeloid leukemia). In addition, 17 other standard strains several multidrug resistant...
Vassobia breviflora belongs to the Solanaceae family, possessing biological activity against tumor cells and is a promising alternative for therapy. The aim of this investigation was determine phytochemical properties V. using ESI-ToF-MS. cytotoxic effects extract were examined in B16-F10 melanoma relationship if any purinergic signaling involved. antioxidant total phenols, (2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid (ABTS) analyzed, as well...
Abstract This study investigates the antioxidant, antimicrobial, and anticancer properties of Pancratium maritimum L. in Sp. Pl.: 291 (1753) seeds flowers. Antioxidant activity was assessed using DPPH free radical scavenging iron chelation assays. Antimicrobial evaluations efficacy extracts against diverse microorganisms. Cell viability assays were conducted on dukes c colon cancer (SW480), while gas chromatography‐mass spectrometry (GC‐MS) analysis facilitated identification bioactive...
This study aimed to identify chemical compounds derived from Vassobia breviflora methanolic extract using ESI-ToF-MS and their antioxidant potential activity utilizing the following methods: total phenols, DPPH, ABTS•+. The MTT assay measured cytotoxic activity, while DCFH-DA nitric oxide assays were employed determine reactive oxygen species (ROS) nitrogen (RNS) levels African green monkey kidney (VERO) human keratinocyte (HaCat) cell lines. minimal inhibitory concentration (MIC)...
Cutaneous melanoma (CM) is an aggressive and metastatic tumor, resulting in high mortality rates. Despite significant advances therapeutics, the available treatments still require improvements. Thus, purinergic signaling emerged as a potential pathway to cancer therapy due its involvement cell communication, proliferation, differentiation, apoptosis. In addition, safety acceptable clinical tolerability, carotenoids from microalgae have been investigated adjuvants anti-melanoma therapy. Then,...
Vassobia breviflora (Sendtn.) Hunz is a plant of the Solanaceae family from South America and there are no apparent studies reported on biological activity hexane extract. The aim this investigation was to conduct phytochemical analyses using ESI-TOF-MS, while antioxidant activities were evaluated by following methods 1,1-diphenyl-2-picrylhydrazyl (DPPH) 2,2“-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) radical capture (ABTS), ferric reducing power (FRAP), total capacity (TAC), oxidant...
