Naringenin-Capped Silver Nanoparticles Amalgamated Gel for the Treatment of Cutaneous Candidiasis. AAPS PharmSciTech 2023; 24:126. [PMID: 37226032 DOI: 10.1208/s12249-023-02581-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Accepted: 05/01/2023] [Indexed: 05/26/2023] Open
Abstract
The current research was aimed to synthesize a phytomolecule, naringenin (NRG)-mediated silver nanoparticles (NRG-SNPs) to study their antifungal potential against Candida albicans (C. albicans) and Candida glabrata (C. glabrata). The NRG-SNPs were synthesized by using NRG as a reducing agent. The synthesis of NRG-SNPs was confirmed by a color change and surface plasmon resonance (SPR) peak at 425 nm. Furthermore, the NRG-SNPs were analyzed for size, PDI, and zeta potential, which were found to be 35 ± 0.21 nm, 0.19 ± 0.03, and 17.73 ± 0.92 mV, respectively. In silico results demonstrated that NRG had a strong affinity towards the sterol 14α-demethylase. The docking with ceramide revealed the skin permeation efficiency of the NRG-SNPs. Next, the NRG-SNPs were loaded into the topical dermal dosage form (NRG-SNPs-TDDF) by formulating a gel using Carbopol Ultrez 10 NF. The MIC50 of NRG solution and TSC-SNPs against C. albicans was found to be 50 µg/mL and 4.8 µg/mL, respectively, significantly (P < 0.05) higher than 0.3625 µg/mL of NRG-SNPs-TDDF. Correspondingly, MIC50 results were calculated against C. glabrata and the results of NRG, TSC-SNPs, NRG-SNPs-TDDF, and miconazole nitrate were found to be 50 µg/mL, 9.6 µg/mL, 0.3625 µg/mL, and 3-µg/mL, respectively. Interestingly, MIC50 of NRG-SNPs-TDDF was significantly (P < 0.05) lower than MIC50 of miconazole nitrate against C. glabrata. The FICI (fractional inhibitory concentration index) value against both the C. albicans and C. glabrata was found to be 0.016 and 0.011, respectively, which indicated the synergistic antifungal activity of NRG-SNPs-TDDF. Thus, NRG-SNPs-TDDF warrants further in depth in vivo study under a set of stringent parameters for translating in to a clinically viable antifungal product.

[PMID: 35386290 PMCID: PMC8979680 DOI: 10.1155/2022/6224107] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 01/20/2022] [Accepted: 03/07/2022] [Indexed: 11/21/2022] Open
Abstract
Objective Acute and subacute toxicity analysis of AND-2-HyP-β-CYD complex was conducted in Sprague-Dawley (SD) rats following oral and inhalation routes of administration. Methods and Results Single dose acute toxicity was carried out at 2000 mg/kg of AND-2-HyP-β-CYD complex, while the doses of 200, 400, and 666 mg/kg were administered, over a period of 28 days under repeated dose oral toxicity study. Hence, LD50 (lethal dose) was found to be >2000 mg/kg in addition to NOAEL (no observed adverse effect level) of 666 mg/kg. Correspondingly, single dose acute inhalation toxicity of AND-2-HyP-β-CYD complex was carried out at 5 mg/L/4 h/day and subacute inhalation toxicity at 0.5, 1, and 1.66 mg/L/4 h/day over a period of 28 days. The NOAEL and LOAEL (lowest observed adverse effect level) were estimated to be 0.5 mg/L/4 h/day and 1 mg/L/4 h/day, respectively. Conclusion The findings of the present study would further be useful in assessing and utilizing the medicinal and therapeutic benefits of AND-2-HyP-β-CYD complex.

Abstract
Silver nanoparticles (Ag NPs) as antibacterial agents are of considerable interest owing to their simplicity, high surface area to volume ratio, and efficient oligodynamic properties. Hence, we investigated the synthesis of silica-supported Ag NPs (SiO2@Ag) as an effective antibacterial agent by using a wet-impregnation method. The formation of SiO2@Ag with Ag NP (5–15 nm diameter) on the silica particle (100–130 nm diameter) was confirmed with transmission electron microscopy (TEM). The study on antibacterial activity was performed in a liquid culture to determine the minimum inhibitory concentration (MIC) against Escherichia coli (E. coli) and Bacillus subtilis (B. subtilis) bacteria. Both bacteria are chosen to understand difference in the effect of Ag NPs against Gram-negative (E. coli) and Gram-positive (B. subtilis) bacteria. SiO2@Ag mesoporous nanoparticles had excellent antibacterial activity against E. coli bacteria and fully restricted the bacterial growth when the material concentration was increased up to 1.00 mg/mL. In addition, the obtained material had good adhesion to both steel and polyethylene substrates and exhibited a high inhibition effect against E. coli bacteria.

Abstract
In present investigation, an attempt was undertaken to modify the C-9 position of noscapine (Nos), an opium alkaloid to yield 9 -hydroxy methyl and 9 -carbaldehyde oxime analogues for augmenting anticancer potential. The synthesis of 9-hydroxy methyl analogue of Nos was carried out by Blanc reaction and 9-carbaldehyde oxime was engineered by oxime formation method and characterized using FT-IR, 1H NMR, 13C NMR, mass spectroscopy, and so on techniques. In silico docking techniques informed that 9-hydroxy methyl and 9-carbaldehyde oxime analogues of Nos had higher binding energy score as compared to Nos. The IC50 of Nos was estimated to be 46.8 µM signficantly (P < 0.05) higher than 8.2 µM of 9-carbaldehyde oxime and 4.6 µM of 9-hydroxy methyl analogue of Nos in U87, human glioblastoma cells. Moreover, there was significant (P < 0.05) difference between the IC50 of 9-carbaldehyde oxime and 9-hydroxy methyl analogue of Nos. Consistent to in vitro cytotoxicity data, 9-hydroxy methyl analogue of Nos induced significantly (P < 0.05) higher degree of apoptosis of 84.6% in U87 cells as compared to 78.5% and 64.3% demonstrated by 9-carbaldehyde oxime and Nos, respectively. Thus the higher therapeutic efficacy of 9-hydroxy methyl analogue of Nos may be credited to higher solubility and inhibitory constant (K).

Abstract
Nanotechnology has the potential to circumvent several drawbacks of conventional therapeutic formulations. In fact, significant strides have been made towards the application of engineered nanomaterials for the treatment of cancer with high specificity, sensitivity and efficacy. Tailor-made nanomaterials functionalized with specific ligands can target cancer cells in a predictable manner and deliver encapsulated payloads effectively. Moreover, nanomaterials can also be designed for increased drug loading, improved half-life in the body, controlled release, and selective distribution by modifying their composition, size, morphology, and surface chemistry. To date, polymeric nanomaterials, metallic nanoparticles, carbon-based materials, liposomes, and dendrimers have been developed as smart drug delivery systems for cancer treatment, demonstrating enhanced pharmacokinetic and pharmacodynamic profiles over conventional formulations due to their nanoscale size and unique physicochemical characteristics. The data present in the literature suggest that nanotechnology will provide next-generation platforms for cancer management and anticancer therapy. Therefore, in this critical review, we summarize a range of nanomaterials which are currently being employed for anticancer therapies and discuss the fundamental role of their physicochemical properties in cancer management. We further elaborate on the topical progress made to date toward nanomaterial engineering for cancer therapy, including current strategies for drug targeting and release for efficient cancer administration. We also discuss issues of nanotoxicity, which is an often-neglected feature of nanotechnology. Finally, we attempt to summarize the current challenges in nanotherapeutics and provide an outlook on the future of this important field.

Abstract
The current study was purported to assess the: (i) in vitro toxicity of betulin silver nanoparticles (AgNPs-B), bare and capped with polyethylene glycol (PEG), on two murine melanoma cell lines (B164A5 and B16Ova) and on healthy cell lines (keratinocytes and melanocytes), and (ii) in vivo antitumor efficacy of PEGylated AgNPs-B in an experimental melanoma model. Bare and PEG-capped AgNPs-B were synthesized by a chemical reduction method resulting in stable and non-aggregated spherical AgNPs-B and PEG-AgNPs-B, of narrow size distributions and mean hydrodynamic diameters of 25 nm and 75 nm, respectively. In vitro assessments were achieved by MTT and Annexin V-FITC assays and in vivo evaluation involved non-invasive techniques for the surveillance of the physiological skin parameters changes and histopathological examination of the harvested organs. The in vitro results revealed selective cytotoxicity against melanoma cells, at low doses that are nontoxic to normal cells; higher doses were associated with the loss of selectivity and toxicity for healthy cells. PEGylated formulation of betulin exerted a dose-dependent pro-apoptotic effect, more obvious in the case of B164A5 cells. Histopathological analysis suggested that PEGylated AgNPs-B developed relevant in vivo effects as antimelanoma agents by decreasing the tumor volume and inhibiting the development of secondary tumors.

Abstract
BACKGROUND AND OBJECTIVE In a phase II clinical trial, carboplatin (CBDCA) displayed the response rate of 19% equivalent to dacarbazine in the treatment of malignant melanoma. However, besides desirable therapeutic profile, intravenous (i.v) administration of CBDCA delivers a subtherapeutic concentration at the target site. This entails administration of CBDCA through an alternate route by using nanovectors to achieve therapeutic efficacy in the treatment of melanoma. METHODS AND RESULTS Carboplatin loaded poly(ε-caprolactone) nanoparticles (CBDCA-PCL-NPs) were formulated and amalgamated with chitosan-β-glycerophosphate gel (CBDCA-PCL-NPs-Gel) for intratumoral (i.t) administration. The mean particle size and zeta-potential of CBDCA-PCL-NPs were determined to be 54.5 ± 6.3-nm and -8.1 ± 0.9-mV, in addition to spherical shape of the nanoformulation. FT-IR spectroscopy denied any issue of chemical incompatibility between drug and polymer. XRD pattern indicated the amorphous lattice of CBDCA-PCL-NPs. The drug loading capacity of CBDCA-PCL-NPs-Gel was estimated to be 152 mg/1 ml. CBDCA-PCL-NPs-Gel demonstrated prolonged drug release up to 48 h. Furthermore, CBDCA-PCL-NPs-Gel displayed the IC50 of 80.3-μM significantly (P < 0.05) lower than 162.8-μM of CBDCA-PCL-NPs and 248.5-μM of CBDCA solution in B16F1, melanoma cancer cells. CBDCA-PCL-NPs-Gel verified 80.2% of apoptosis significantly (P < 0.01) higher than 57.6% of CBDCA-PCL-NPs and 43.4% of CBDCA solution. Continuation to this, CBDCA-PCL-NPs-Gel significantly (P < 0.01) suppressed the tumor volume to 95.5 ± 8.4-mm3 as compared to 178.9 ± 10.2-mm3 of CBDCA solution injected i.t. and 210.6 ± 17.1-mm3 displayed by CBDCA solution injected i.v. vis-à-vis 815.4 ± 17.1-mm3 tumor volume of B16F1 tumor bearing C57BL6J mice. CONCLUSION The promising preclinical results of CBDCA-PCL-NPs-Gel warrant further investigations under a set of stringent parameters for the treatment of melanoma.
