Enhancing the efficacy of zinc oxide nanoparticles by beta-carotene conjugation for improved anti-microbial and anti-tumor therapy for dental application. Pharm Dev Technol 2025; 30:101-113. [PMID: 39737541 DOI: 10.1080/10837450.2024.2448620] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2024] [Revised: 12/27/2024] [Accepted: 12/27/2024] [Indexed: 01/01/2025]
Abstract
Zinc oxide NPs (ZnO NPs) are notable in nanomedicine for their exceptional physicochemical and biological properties. This study synthesizes and characterizes beta-carotene-coated ZnO NPs (BT-ZnO NPs) for potential anti-cancer and antimicrobial applications, demonstrating significant efficacy against dental pathogens and oral cancer cells. Scanning Electron Microscopy, EDAX, UV, FTIR, XRD, and Zeta potential analysis of prepared BT-ZnO NPs revealed uniform flower-like crystalline structures with intricate morphology and an average particle size of 38.06 nm. FTIR spectra identified various functional groups, suggesting a complex organic compound coated with ZnO NPs. Zeta potential measurements showed pH-dependent surface charge variations, which are crucial for understanding colloidal stability. The antimicrobial activity was potent against dental pathogens, with minimum inhibitory concentration (MIC) values of 50 µg/mL highlighting significant inhibition. Molecular docking studies demonstrated strong binding affinities of BT to key receptor proteins of dental pathogens. BT-ZnO NPs exhibited notable antioxidant activity of 68%, comparable to ascorbic acid, and significant anti-inflammatory effects of 75.1% at 100 µg/mL. Cytotoxicity assays indicated a concentration-dependent suppression of KB cell proliferation, decreasing cell viability to 37.19%, and gene expression studies showed elevated P53 expression, suggesting a strong apoptotic response. These multifaceted properties underscore the potential of BT-ZnO NPs as an integrated therapeutic approach for dental healthcare and oncology.

Baeza-Morales A, Medina-García M, Martínez-Peinado P, Pascual-García S, Pujalte-Satorre C, López-Jaén AB, Martínez-Espinosa RM, Sempere-Ortells JM. The Antitumour Mechanisms of Carotenoids: A Comprehensive Review. Antioxidants (Basel) 2024; 13:1060. [PMID: 39334719 PMCID: PMC11428676 DOI: 10.3390/antiox13091060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2024] [Revised: 08/20/2024] [Accepted: 08/22/2024] [Indexed: 09/30/2024] Open
Abstract
Carotenoids, known for their antioxidant properties, have garnered significant attention for their potential antitumour activities. This comprehensive review aims to elucidate the diverse mechanisms by which carotenoids exert antitumour effects, focusing on both well-established and novel findings. We explore their role in inducing apoptosis, inhibiting cell cycle progression and preventing metastasis by affecting oncogenic and tumour suppressor proteins. The review also explores the pro-oxidant function of carotenoids within cancer cells. In fact, although their overall contribution to cellular antioxidant defences is well known and significant, some carotenoids can exhibit pro-oxidant effects under certain conditions and are able to elevate reactive oxygen species (ROS) levels in tumoural cells, triggering mitochondrial pathways that would lead to cell death. The final balance between their antioxidant and pro-oxidant activities depends on several factors, including the specific carotenoid, its concentration and the redox environment of the cell. Clinical trials are discussed, highlighting the conflicting results of carotenoids in cancer treatment and the importance of personalized approaches. Emerging research on rare carotenoids like bacterioruberin showcases their superior antioxidant capacity and selective cytotoxicity against aggressive cancer subtypes, such as triple-negative breast cancer. Future directions include innovative delivery systems, novel combinations and personalized treatments, aiming to enhance the therapeutic potential of carotenoids. This review highlights the promising yet complex landscape of carotenoid-based cancer therapies, calling for continued research and clinical exploration.

Disease Prevention and Treatment Using β-Carotene: the Ultimate Provitamin A. REVISTA BRASILEIRA DE FARMACOGNOSIA : ORGAO OFICIAL DA SOCIEDADE BRASILEIRA DE FARMACOGNOSIA 2022; 32:491-501. [PMID: 35669276 PMCID: PMC9150880 DOI: 10.1007/s43450-022-00262-w] [Citation(s) in RCA: 19] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Accepted: 05/06/2022] [Indexed: 12/14/2022]
Abstract
Humans being unable to synthesize beta-carotene, the provitamin A, depend on external sources as its supplement. Health benefits and dietary requirements of beta-carotene are interrelated. This orange-red coloured pigment has been enormously examined for its capacity to alleviate several chronic diseases including various types of cancer, cystic fibrosis, as well as COVID-19. However, this class of phytoconstituents has witnessed a broad research gap due to several twin conclusions that have been reported. Natural sources for these compounds along with their extraction methods have been mentioned. The current communication aims at contributing to the global scientific literature on beta-carotene’s application in prevention and treatment of lifestyle diseases.
