Abstract
Crystalline solid dispersions (CSDs) represent a thermodynamically stable system capable of effectively reducing the crystallite size of drugs, thereby enhancing their solubility and bioavailability. This study uses flavonoid drugs with the same core structures but varying numbers of hydroxyl groups as model drugs and poloxamer 188 as a carrier to explore the intrinsic relationships between drug-polymer interactions, crystallite size, and in vitro dissolution behavior in CSDs. Initially, we investigate the interactions between flavonoid drugs and P188 by calculating Hansen solubility parameters, determination of Flory-Huggins interaction parameters, and other methods. Subsequently, we explore the crystallization kinetics of flavonoid drugs and P188 in CSD systems using polarized optical microscopy and powder X-ray diffraction. We monitor the domain size and crystallite size of flavonoids in CSDs through powder X-ray diffraction and a laser-particle-size analyzer. Finally, we validate the relationship between crystallite size and in vitro dissolution behavior through powder dissolution. The results demonstrate that, as the number of hydroxyl groups increases, the interactions between drugs and polymers become stronger, making drug crystallization in the CSD system less likely. Consequently, reductions in crystalline domain size and crystallite size become more pronounced, leading to a more significant enhancement in drug dissolution.

Abstract
A significant proportion of pharmaceuticals are now considered multiparticulate systems. Modified-release drug delivery formulations can be designed with engineering precision, and patient-centric dosing can be accomplished relatively easily using multi-unit systems. In many cases, Multiple-Unit Pellet Systems (MUPS) are formulated on the basis of a neutral excipient core which may carry the layered drug surrounded also by functional coating. In the present summary, commonly used starter pellets are presented. The manuscript describes the main properties of the various nuclei related to their micro- and macrostructure. In the case of layered pellets formed based on different inert pellet cores, the drug release mechanism can be expected in detail. Finally, the authors would like to prove the industrial significance of inert cores by presenting some of the commercially available formulations.

Abstract
Boswellic acids (BAs) are the main bioactive compounds of frankincense, a natural resin obtained from the genus Boswellia. This study aimed to develop a self-nanoemulsifying delivery system (SNEDS) to improve the antimicrobial and antiproliferative activities of standardized frankincense extract (Fr-extract). Fr-extract was standardized, and BA content was quantified using the developed HPLC-UV method. Screening studies of excipients followed by formula optimization using a mixture simplex lattice design was employed. The optimized Fr-SENDS formulation was characterized. Furthermore, microbiological and antiproliferative assessments of the standardized Fr-extract and Fr-SNEDS were evaluated. Quantification demonstrated that the major constituent is 11-keto-boswellic acid (KBA) (16.25%) among BA content (44.96%). The optimized Fr-SENDS (composed of 5% CapryolTM 90, 48.7% Gelucire® 44/14 and 46.3% ethanol) showed spherical nanosized dispersions with DS, PDI, and zeta potential of 17.9 nm, 0.2, and −14.5 mV, respectively. Fr-SNEDS exhibited lower MIC and MBC values compared with Fr-extract against pathogens conjugated with lung cancer and was comparable to reference antimicrobials. Fr-SNEDS showed superior antiproliferative activity over Fr-extract, with IC50 values of 20.49 and 109.5 μg mL−1, respectively. In conclusion, the optimized Fr-SNEDS could be easily developed and manufactured at a low cost and the in vitro results support its use as a potential adjuvant oral therapy for lung cancer. Further in vivo studies could be continued to assess the therapeutic efficiency of the prepared system.

Abstract
BACKGROUND This study was designed as a continuation of a complex investigation about the phytochemical composition and biological activity of chamomile, parsley, and celery extracts against A375 human melanoma and dendritic cells. OBJECTIVE The main aim was the evaluation of the antimicrobial potential of selected extracts as well as the in vitro anticancer activity against MCF7 human breast cancer cells. METHODS In order to complete the picture regarding the phytochemical composition, molecular fingerprint was sketched out by the help of FTIR spectroscopy. The activity of two enzymes (acetylcholinesterase and butyrylcholinesterase) after incubation with the three extracts was spectrophotometrically assessed. The antimicrobial potential was evaluated by disk diffusion method. The in vitro anticancer potential against MCF7 human breast cancer cells was appraised by MTT, LDH, wound healing, cell cycle, DAPI, Annexin-V-PI assays. RESULTS The results showed variations between the investigated extracts in terms of inhibitory activity against enzymes, such as acetyl- and butyrilcholinesterase. Chamomile and parsley extracts were active only against tested Gram-positive cocci, while all tested extracts displayed antifungal effects. Among the screened samples at the highest tested concentration, namely 60μg/mL, parsley was the most active extract in terms of reducing the viability of MCF7 - human breast adenocarcinoma cell line and inducing the release of lactate dehydrogenase. On the other hand, chamomile and celery extracts manifested potent anti-migratory effects. Furthermore, celery extract was the most active in terms of total apoptotic events, while chamomile extract induced the highest necrosis rate. CONCLUSION The screened samples containing phytochemicals belonging in majority to the class of flavonoids and polyphenols can represent candidates for antimicrobial and anticancer agents.

Abstract
Amentoflavone, robustaflavone, 2″,3″-dihydro-3′,3‴-biapigenin, 3′,3‴-binaringenin, and delicaflavone are five major hydrophobic components in the total biflavonoids extract from Selaginella doederleinii (TBESD) that display favorable anticancer properties. The purpose of this study was to develop a new oral delivery formulation to improve the solubilities, dissolution rates, and oral bioavailabilities of the main ingredients in TBESD by the solid dispersion technique. Solid dispersions of TBESD with various hydrophilic polymers were prepared, and different technologies were applied to select the suitable carrier and method. TBESD amorphous solid dispersion (TBESD-ASD) with polyvinylpyrrolidone K-30 was successfully prepared by the solvent evaporation method. The physicochemical properties of TBESD-ASD were investigated by scanning electron microscopy, differential scanning calorimetry, and Fourier-transform infrared spectroscopy. As a result, TBESD was found to be molecularly dispersed in the amorphous carrier. The solubilities and dissolution rates of all five ingredients in the TBESD-ASD were significantly increased (nearly 100% release), compared with raw TBESD. Meanwhile, TBESD-ASD showed good preservation stability for 3 months under accelerated conditions of 40 °C and 75% relative humidity. A subsequent pharmacokinetic study in rats revealed that Cmax and AUC0–t of all five components were significantly increased by the solid dispersion preparation. An in vivo study clearly revealed that compared to raw TBESD, a significant reduction in tumor size and microvascular density occurred after oral administration of TBESD-ASD to xenograft-bearing tumor mice. Collectively, the developed TBESD-ASD with the improved solubility, dissolution rates and oral bio-availabilities of the main ingredients could be a promising chemotherapeutic agent for cancer treatment.

Abstract
The present study was designed to develop multifunctional zinc oxide-encapsulated Eudragit FS30D (ZnO/EFS) nanohybrid structures as a biodegradable drug delivery system and as a promising successful carrier for targeting sites. The solvent evaporation method was used to fabricate the ZnO/EFS nanohybrids and the size, shape, stability, and antioxidant activity were characterized using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), thermogravimetric analysis (TGA), and an antioxidant (1,1-diphenyl-2-picrylhydrazyl (DPPH)). Zinc oxide-encapsulated Eudragit FS30D (ZnO/EFS) nanohybrid structures consisted of irregularly shaped, 297.65 nm-sized ZnO/EFS microcapsule, enduring thermal stability from 251.17 to 385.67 °C. Nano-ZnO was encapsulated in EFS through the formation of hydrogen bonds, and the average encapsulation efficiency for nano-ZnO was determined to be 96.12%. In vitro intestinal-targeted drug release assay provided 91.86% with free nano-ZnO, only 9.5% in acidified ZnO/EFS nanohybrid structure but the rate ZnO/EFS nanohybrids reached 93.11% in succus entericus resultantly modified nano-ZnO was proven proficient intestinal-specific delivery system. The stability of the ZnO/EFS nanohybrid structures was confirmed using ζ-potential and antioxidant activity analysis. Hence, the EFS nanoencapsulation strategy of ZnO provided a stable, nontoxic, and pharmacokinetically active intestine-specific system that can become the best choice for an effective oral feed additive in future.

Abstract
Background Fool's watercress (Apium nodiflorum) is an edible vegetable with potential as a new crop. However, little information is available regarding the antioxidant properties of the plant and the individual phenolics accounting for this capacity are unknown. Methods The antioxidant properties of twenty-five wild populations were analysed and individual phenolics present in the species reported and compared with celery and parsley. The antioxidant activity was measured as the 2,2-diphenyl-1-picrylhydrazyl hydrate (DPPH) free radical scavenging capacity, and the total phenolics content (TPC) via the Folin-Ciocalteu procedure. The individual phenolics constituents were determined via high performance liquid chromatography (HPLC) as aglycones. Results The average DPPH and TPC of fool's watercress were 28.1 mg Trolox g-1 DW and 22.3 mg of chlorogenic acid equivalents g-1 DW, respectively, much higher than those of celery and parsley. Significant differences for both DPPH and TPC, which may be explained by either genotype or environmental factors, were detected among groups established according to geographical origin. Quercetin was identified as the major phenolic present in the leaves of the species, unlike parsley and celery, in which high amounts of apigenin and luteolin were determined. Quercetin represented 61.6% of the phenolics targeted in fool's watercress, followed by caffeic acid derivatives as main hydroxycinnamic acids. Discussion The study reports the high antioxidant properties of fool's watercress based on a large number of populations. Results suggest that quercetin accounts for an important share of the antioxidant capacity of this potential new crop. The study also provides a basis for future breeding programs, suggesting that selection by geographical locations may result in differences in the antioxidant properties.
