N-Acylethanolamines are signaling lipid mols. implicated in pathophysiol. conditions associated with inflammation and pain. N-Acylethanolamine acid amidase (NAAA) favorably hydrolyzes lipid palmitoylethanolamide, which plays a key role in the regulation of inflammatory and pain processes. The synthesis and structure-activity relationship studies encompassing the isothiocyanate pharmacophore have produced potent low nanomolar inhibitors for hNAAA, while exhibiting high selectivity (>100-fold) against other serine hydrolases and cysteine peptidases. We have followed a target-based structure-activity relationship approach, supported by computational methods and known cocrystals of hNAAA. We have identified systemically active inhibitors with good plasma stability (t_1/2 > 2 h) and microsomal stability (t_1/2 ∼ 15-30 min) as pharmacol. tools to investigate the role of NAAA in inflammation, pain, and drug addiction.

Malacarne, Miryam Chiara;Banfi, Stefano;Rugiero, Matteo;Caruso, Enrico research published 《 Drug delivery systems for the photodynamic application of two photosensitizers belonging to the porphyrin family》, the research content is summarized as follows. Photodynamic therapy involves the concomitant action of three components, light with an appropriate wavelength, mol. oxygen, and a mol., able to absorb an electromagnetic radiation, called photosensitizer (PS). A fundamental aspect is the bioavailability of the PS that is directly related to some physicochem. properties of the PS itself as it should feature a certain degree of lipophilicity to easily cross the cell membrane, however, at the same time, should be sufficiently water-soluble to navigate in the bloodstream. Consequently, the use of a system for drug delivery becomes essential when photosensitizers with a high degree of lipophilicity are considered. In this work, we present three different drug delivery systems, microemulsions, emulsions and liposomes all capable of carrying a PS belonging to the porphyrin family: the tetra-Ph porphyrin (TPP) and the 4-hydroxyphenyl porphyrin (THPP), which show a relevant different degree of lipophilicity. A series of microemulsions (ME) and emulsions (E) were prepared, among which two formulations, one for THPP and one for TPP, have been chosen. The stability of these two carriers was monitored over time and under various temperature conditions. With the same criteria, two liposomal formulations have been also identified and analyzed. The four formulations mentioned above (one ME, one E and two liposomes) have been tested on SKOV3 tumor cell line comparing the photodynamic activity of the porphyrin formulations vs. the aqueous/organic (DMSO) solution of the same two PSs. The results show that all the formulations have proved to be excellent carriers and that the liposomal formulation enhance the photodynamic efficacy of both porphyrins.

Evidence that hepatitis C virus (HCV) utilizes cellular cyclophilin proteins in the virus replication cycle has increased attention on cyclophilin inhibitors as attractive therapeutic targets in the treatment of HCV. Previous reports have described a number of non-immunosuppressive cyclophilin inhibitors, most of which require many synthetic steps for their preparation Sasamura et al. have previously reported the isolation of bioconversion derivative 4. This analog is a convenient starting point for optimization due to the presence of the readily modifiable primary hydroxyl group and because it shows moderate anti-HCV activity and decreased immunosuppressive activity. We have also established an efficient C-alkylation reaction at the 3-position. Through a detailed structure-activity relationship study, we discovered a new type of clin. candidate 14(I) which requires a short synthetic process and has potent anti-HCV activity and reduced immunosuppressive activity, as well as improved aqueous solubility and pharmacokinetics.

Maharjan, Ravi;Jeong, Junoh;Bhujel, Ripesh;Kim, Min-Soo;Han, Hyo-Kyung;Kim, Nam Ah;Jeong, Seong Hoon research published 《 Correlation of Solubility Thermodynamics of Glibenclamide with Recrystallization and In Vitro Release Profile》, the research content is summarized as follows. The solubility of glibenclamide was evaluated in DMSO, NMP, 1,4-dioxane, PEG 400, Transcutol HP, water, and aqueous mixtures (T = 293.15∼323.15 K). It was then recrystallized to solvate and compressed into tablets, of which 30-day stability and dissolution was studied. It had a higher solubility in 1,4-dioxane, DMSO, NMP (X_exp = 2.30 × 10³, 3.08 × 10⁴, 2.90 × 10⁴) at 323.15 K, its mixture (X_exp = 1.93 × 10³, 1.89 × 10⁴, 1.58 × 10⁴) at 298.15 K, and 1,4-dioxane (ω) + water (1-ω) mixture ratio of w = 0.8 (X_exp = 3.74 × 10³) at 323.15 K. Modified Apelblat (RMSD ≤ 0.519) and CNIBS/R-K model (RMSD ≤ 0.358) suggested good comparability with the exptl. solubility The min. value of ΔG° vs ΔH° at 0.70 < x₂ < 0.80 suggested higher solubility at that molar concentration Based on the solubility, it was recrystallized into the solvate, which was granulated and compressed into tablets. Among the studied solvates, the tablets of glibenclamide dioxane solvate had a higher initial (95.51%) and 30-day (93.74%) dissolution compared to glibenclamide reference (28.93%). There was no stability issue even after granulation, drying, or at pH 7.4. Thus, glibenclamide dioxane solvate could be an alternative form to improve the mol.’s properties.

Mahadev, Manohar;Nandini, Hittanahalli S.;Ramu, Ramith;Gowda, Devegowda V.;Almarhoon, Zainab M.;Al-Ghorbani, Mohammed;Mabkhot, Yahia N. research published 《 Fabrication and Evaluation of Quercetin Nanoemulsion: A Delivery System with Improved Bioavailability and Therapeutic Efficacy in Diabetes Mellitus》, the research content is summarized as follows. The current study was intended to fabricate and evaluate ultrasonically assisted quercetin nanoemulsion (Que-NE) for improved bioavailability and therapeutic effectiveness against diabetes mellitus in rats. Et oleate, Tween 20, and Labrasol were chosen as oil, surfactant, and cosurfactant, resp. Box-Behnken design (BBD) was employed to study the influence of process variables such as % surfactant and cosurfactant mixture (Smix) (5 to 7%), % amplitude (20-30%) and sonication time (2.5-7.5 min) on droplet size, polydispersibility index (PDI), and % entrapment efficiency (%EE) were studied. The optimization predicted that 9% Smix at 25% amplitude for 2.5 min would produce Que-NE with a droplet size of 125.51 nm, 0.215 PDI, and 87.04% EE. Moreover, the optimized Que-NE exhibited appreciable droplet size and PDI when stored at 5, 30, and 40°C for 45 days. Also, the morphol. characterization by transmission electron microscope (TEM) indicated the spherical shape of the optimized nanoemulsion. Furthermore, the Que-NE compared to pure quercetin exhibited superior release and enhanced oral bioavailability. The streptozocin-induced antidiabetic study in rats revealed that the Que-NE had remarkable protective and therapeutic properties in managing body weight, blood glucose level, lipid profile, and tissue injury markers, alongside the structure of pancreatic β-cells and hepatocytes being protected. Thus, the developed Que-NE could be of potential use as a substitute strategy for diabetes.

Maddala, Sudhakar;Panua, Anirban;Venkatakrishnan, Parthasarathy research published 《 Steering Scholl Oxidative Heterocoupling by Tuning Topology and Electronics for Building Thiananographenes and Their Functional N-/C-Congeners》, the research content is summarized as follows. This report systematically demonstrates how topol. variation of electronics and reactivity in thiophene substrates can lead to efficient oxidative heterocoupling. Bis(biaryl)thiophenes having reactive α- and β-positions open are the choice of substrates. The cyclizing arene partners are so electronically tuned for thiophene’s reactivity (at α- and β-) as to establish C-C bond oxidatively generating sym. as well as unsym. diphenanthrothiophenes which are basic thiananographenes. Depending on the cyclizing-couple’s electronics, either arene- or thiophene-centered oxidation initiates C-C heterocoupling. The potential utility of these simple thiananographenes is further unfurled by converting them to functional N-/C-graphene segments that are aza-corannulene precursor and tetrabenzospirobifluorene. Their bright emission and extended electrochem. stability are remarkable that may be potentially important and applicable.

Ma, Yan;Wang, Pei;Gu, Zhenxin;Sun, Maomao;Yang, Runqiang research published 《 Effects of germination on physio-biochemical metabolism and phenolic acids of soybean seeds》, the research content is summarized as follows. In this study, changes of phenolic acids and antioxidant capacity during germination of soybean seeds were investigated. Results revealed that germination enhanced sprout growth, changed endogenous phytohormones level and caused oxidative damage, but enhanced phenolic acids accumulation. Eight individual phenolic acids in soybean sprouts were identified by HPLC. Gallic acid and protocatechuic acid mainly present in free form, while vanillic acid mainly present in bound form, and p-hydroxybenzoic acid, syringic acid, p-coumaric acid, ferulic acid and sinapic acid were both identified in free and bound phenolic extracts Both free and bound phenolic acids contents significantly increased during germination. The enzymes activities of phenylalanine ammonia lyase (PAL), cinnamic acid 4-hydroxylase (C4H) and 4-coumarate CoA ligase (4CL) that participated in the biosynthesis of phenolic acids were up-regulated. These results contribute to the further insights into the health-promoting compounds of soybean sprouts.

Ma, Qiuyan;Zhang, Jing;Lu, Bohong;Lin, Huaqing;Sarkar, Rajib;Wu, Tao;Li, Xuee research published 《 Nanoemulgel for Improved Topical Delivery of Desonide: Formulation Design and Characterization》, the research content is summarized as follows. This research aimed to develop a novel drug delivery system to improve treatment of skin disorders. The system is comprised of a Carbopol 980-based nanoemulgel (NE-gel) containing a desonide (DES; 0.05%, weight/weight) nanoemulsion (NE), which has a small particle size, high encapsulation efficiency, good thermodn. stability, good permeation ability, and high skin retention. DES-loaded NE (DES-NE) was prepared by high-pressure homogenization. The developed formulation was characterized by differential scanning calorimetry (DSC), X-ray diffraction, drug release, skin permeation, and drug retention. DES in vitro release and skin permeation studies with different formulations of artificial membrane and rat abdominal skin were performed with the Franz diffusion cell system. Confocal laser scanning microscopy (CLSM) was used to detect the localization and permeation pathways of drugs in the skin. Compared with com. available gel (CA-gel) and NE, the NE-gel release process conformed to the Higuchi release model (R2 = 0.9813). NE-gel prolonged the drug release time and allowed for reduced administration dose and frequency. The unit cumulative permeation of NE and NE-gel through the skin for 12 h was 63.13 ± 2.78 and 42.53 ± 2.06μg/cm², resp., values significantly higher (p < 0.01) than that of the CA-gel (30.65 ± 1.25μg/cm²) and CA-cream (15.21 ± 0.97μg/cm²). The DES-NE and DES NE-gel skin drug retention was significantly higher than com. available formulations (p < 0.01). Hence, the prepared NE-gel is a potential vehicle for improved topical DES delivery for better treatment of skin disorders.

Luo, Zheng;Liu, Chao;Quan, Peng;Zhang, Yimeng;Fang, Liang research published 《 Effect of Chemical Penetration Enhancer-Adhesive Interaction on Drug Release from Transdermal Patch: Mechanism Study Based on FT-IR Spectroscopy, ¹³C NMR Spectroscopy, and Molecular Simulation》, the research content is summarized as follows. Chem. penetration enhancers (CPEs) are commonly added into transdermal patches to impart improved skin permeation of drug. However, significant unexplained variability in drug release kinetics in transdermal patches is possible as a result of the addition of CPEs; investigations into the underlying mechanisms are still limited. In the present study, a diverse set of CPEs was employed to draw broad conclusions. Solubility parameters of CPEs and acrylate pressure-sensitive adhesive were calculated by mol. dynamics simulation and Fedors group contribution method to evaluate drug-adhesive miscibility. CPE-adhesive interaction was characterized by FT-IR study, ¹³C NMR spectroscopy, and mol. docking simulation. Results showed that release enhancement ratio (ERR) of CPEs for zolmitriptan was rank ordered as iso-Pr myristate > azone > Plurol Oleique CC497 > Span 80 > N-methylpyrrolidone > Transcutol P. It was found that solubility parameter difference (Δδ) between CPE and adhesive was neg. related with ERR. It was proved that hydrogen bonding between CPE and adhesive would increase drug release rate, but only if the CPE showed good miscibility with adhesive. CPE like iso-Pr myristate, which had good miscibility with adhesive, could decrease drug-adhesive interaction leading to the release of drug from adhesive.
