Katiyar S, Srivastava N, Choudhury AR. Microbial fermentation-based synthesis of nano-curcumin suggesting the role of pullulan in nano-formulation. Int J Biol Macromol 2024; 265:131088. [PMID: 38521315 DOI: 10.1016/j.ijbiomac.2024.131088] [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: 11/22/2023] [Revised: 03/16/2024] [Accepted: 03/20/2024] [Indexed: 03/25/2024]
Abstract
Curcumin is a multitargeting nutraceutical with numerous health benefits, however, its efficacy is limited due to poor aqueous solubility and reduced bioavailability. While nano-formulation has emerged as an alternative to encounter such issues, it often involves use of toxic solvents. Microbial synthesis may be an innovative solution to address this lacuna. Present study, for the first time, reports exploitation of Aureobasidium pullulans RBF4A3 for production of nano-curcumin. For this purpose, Aureobasidium pullulans RBF4A3 was inoculated in YPD media along with curcumin (0.1 mg/mL) and incubated for 24 h, 48 h, and 72 h. Subsequently, residual sugar, biomass, EPS concentration, curcumin concentration, and curcumin nanoparticle size were measured. As a result, nano-curcumin with an average particle size of 31.63 nm and enhanced aqueous solubility was obtained after 72 h. Further, investigations suggested that pullulan, a reducing polysaccharide, played a significant role in curcumin nano-formulation. Pullulan-mediated nano-curcumin formulation, with an average particle size of 24 nm was achieved with conversion rate of around 59.19 %, suggesting improved aqueous solubility. Additionally, the anti-oxidant assay of the resulting nano-curcumin was around 53.7 % per μg. Moreover, kinetics and thermodynamic studies of pullulan-based nano-curcumin revealed that it followed first-order kinetics and was favored by elevated temperature for efficient bio-conversion. Also, various physico-chemical investigations like FT-IR, NMR, and XRD reveal that pullulan backbone remains intact while forming curcumin nanoparticle. This study may open up new avenues for synthesizing nano-polyphenols through a completely green and solvent free process with plausible diverse applications.

Production and Anti-Inflammatory Performance of PVA Hydrogels Loaded with Curcumin Encapsulated in Octenyl Succinic Anhydride Modified Schizophyllan as Wound Dressings. Molecules 2023; 28:molecules28031321. [PMID: 36770985 PMCID: PMC9921521 DOI: 10.3390/molecules28031321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2022] [Revised: 01/25/2023] [Accepted: 01/27/2023] [Indexed: 01/31/2023] Open
Abstract
Amphiphilic polysaccharides can be used as wall materials and applied to encapsulate hydrophobic active chemicals; moreover, there is significant demand for novel medical high-molecular-weight materials with various functions. In order to prepare amphiphilic schizophyllan (SPG), octenyl succinic anhydride (OSA) was chosen to synthesize OSA-modified schizophyllan (OSSPG) using an esterified reaction. The modification of OSSPG was demonstrated through FT-IR and thermal analysis. Moreover, it was found that OSSPG has a better capacity for loading curcumin, and the loading amount was 20 μg/mg, which was 2.6 times higher than that of SPG. In addition, a hydrogel made up of PVA, borax, and C-OSSPG (OSSPG loaded with curcumin) was prepared by means of the one-pot method, based on the biological effects of curcumin and the immune-activating properties of SPG. The mechanical properties and biological activity of the hydrogel were investigated. The experimental results show that the dynamic cross-linking of PVA and borax provided the C-OSSPG/BP hydrogel dressing with exceptional self-healing properties, and it was discovered that the C-OSSPG content increased the hydrogel's swelling and moisturizing properties. In fibroblast cell tests, the cells treated with hydrogel had survival rates of 80% or above. Furthermore, a hydrogel containing C-OSSPG could effectively promote cell migration. Due to the excellent anti-inflammatory properties of curcumin, the hydrogel also significantly reduces the generation of inflammatory factors, such as TNF-α and IL-6, and thus has a potential application as a wound dressing medicinal material.

Abstract
Overdosage of antibiotics used to prevent bacterial infections in the human and animal gastrointestinal tract would result in disturbing of intestinal barrier, significant misbalancing effects of intestinal microflora and persuading bacterial resistance. The main objective of the present investigation is to design and develop novel combinations of organic curcumin (Cur) and antimicrobial peptide (Amp) loaded chitosan nanoformulations (Cur/Amp@CS NPs) to improve significant effects on antibacterial action, immune response, intestine morphology, and intentional microflora. The antibacterial efficiency of the prepared nanoformulations was evaluated using Escherichia coli (E. coli) induced bacterial infections in GUT of Rat models. Further, we studied the cytocompatibility, inflammatory responses, α-diversity, intestinal morphology, and immune responses of treated nanoformulations in rat GUT models. The results indicated that Cur/Amp@CS NPs are greatly beneficial for intestinal microflora and could be a prodigious alternative of antibiotics.

Abstract
Abstract
In order to accomplish efficient mixing of liquids with large differences in flow rates, an efficient multi-orifice impinging transverse (MOIT) jet mixer is used in this paper. Its structure combines a conventional MOIT jet mixer with a venturi jet mixer to improve the mixing efficiency of the MOIT jet mixer. The flow characteristics and mixing effects inside the conventional and efficient jet mixer are numerically simulated by means of a Multiphase Models. Based on building the experimental platform, the maximum error between the simulation results and the experimental results obtained with the high-speed camera is 8.42%, which verifies that the model and simulation method applies to the simulation of the mixer. In addition, the paper uses MATLAB software to obtain the interphase contact area at the transverse orifice section and verifies that the contact area at the transverse orifice section affects the mixing effect of the mixer. The droplet size distribution was also analyzed by the CFD-PBM model. The results show that the efficient MOIT jet mixer has better mixing efficiency and mixing effect, and the optimal values of the number of orifices and main fluid flow rate of the jet mixer exist. In addition, the mixing effect of the mixer showed a decreasing trend with the increase of the orifice size. The results of this paper complete the optimization of the parameters of the MOIT jet mixer, facilitating its industrial application. And combining two different mixers to create a novel jet mixer, which provides a direction for the development of new jet mixers and helps to promote the development of the fine chemical industry.

Abstract
Oral delivery of curcumin (CUR) has limited effectiveness due to CUR’s poor systemic bioavailability caused by its first-pass metabolism and low solubility. Buccal delivery of CUR nanoparticles can address the poor bioavailability issue by virtue of avoidance of first-pass metabolism and solubility enhancement afforded by CUR nanoparticles. Buccal film delivery of drug nanoparticles, nevertheless, has been limited to low drug payload. Herein, we evaluated the feasibilities of three mucoadhesive polysaccharides, i.e., hydroxypropyl methylcellulose (HPMC), starch, and hydroxypropyl starch as buccal films of amorphous CUR–chitosan nanoplex at high CUR payload. Both HPMC and starch films could accommodate high CUR payload without adverse effects on the films’ characteristics. Starch films exhibited far superior CUR release profiles at high CUR payload as the faster disintegration time of starch films lowered the precipitation propensity of the highly supersaturated CUR concentration generated by the nanoplex. Compared to unmodified starch, hydroxypropyl starch films exhibited superior CUR release, with sustained release of nearly 100% of the CUR payload in 4 h. Hydroxypropyl starch films also exhibited good payload uniformity, minimal weight/thickness variations, high folding endurance, and good long-term storage stability. The present results established hydroxypropyl starch as the suitable mucoadhesive polysaccharide for high-payload buccal film applications.

Abstract
The aim of the present study was to prepare curcumin nanoparticles (nanocurcumin) by a sol-oil method to improve curcumin absorption and bioavailability, and to investigate the therapeutic effects of the prepared nanoparticles on the inhibition mechanisms towards human Hep-2 cancer cells. The nanoparticles were characterized by Fourier transform infrared spectroscopy, transmission electron microscopy, X-ray diffraction, and zeta potential analysis. The prepared curcumin nanoparticles possessed a narrow particle size distribution with an average diameter of 28 nm. The inhibition effects on the growth of human Hep-2 cells were investigated using neutral red uptake and lactate dehydrogenase assays. The results indicated that the nanocurcumin has a selective effect in inhibiting Hep-2 cell growth in a dose- and time-dependent mode with the most effective IC50 value (17 ± 0.31 μg ml−1) obtained after 48 h of incubation without any cytotoxic effects on normal cells. This IC50 value of nanocurcumin revealed a significant increase of early and late apoptotic cells with an intense comet nucleus of Hep-2 cells as a marker of DNA damage. Flow cytometry analysis of the progression of apoptosis in nanocurcumin Hep-2 treated cells showed that arresting in the cell cycle in the G2/M phase with increasing apoptotic cells in the sub-G1 phase. At the same time, real-time PCR analysis indicated that the treatment of Hep-2 cells with nanocurcumin resulted in upregulation of P53, Bax, and Caspase-3, whereas there was downregulation of Bcl-XL. These findings gave insights into understanding that the inhibition mechanisms of nanocurcumin on the proliferation of Hep-2 cancer cells was through the G2/M cell cycle arrest and the induction of apoptosis was dependent on Caspase-3 and p53 activation. However, in vivo studies with an animal model are essential to validate these results. The aim of this study was to prepare curcumin nanoparticles using a sol–oil method to improve curcumin absorption and bioavailability, and to investigate the therapeutic effect of the prepared nanoparticles on the inhibition mechanisms toward human Hep-2 cancer cells.![]()
