Echeverry, Sandra M.;Rey, Diana;Valderrama, Ivonne H.;Araujo, Bibiana Verlindo de;Aragon, Diana Marcela research published 《 Development of a self-emulsifying drug delivery system (SEDDS) to improve the hypoglycemic activity of Passiflora ligularis leaves extract》, the research content is summarized as follows. This work aimed to develop, optimize, and evaluate the hypoglycemic activity of P. ligularis leaves extract (PLE) loaded self-emulsifying drug delivery system (SEDDS). The formulation components (oil, surfactant, and co-solvent) were selected based on the solubility studies. A Box-Behnken design (BBD) with 27 treatments was employed to find the optimal composition of PLE-SEDDS, analyzing the droplet size as the response variable. The polydispersity index (PDI) and zeta potential parameters were also measured. The pharmacol. activity was evaluated through a glucose tolerance test. According to ANOVA for the droplet size variable, the linear model was highly significant (p < 0.001), and oil, surfactant, co-solvent, and silicone polymer (PDMSHEPMS) content and their interactions were statistically significant. The final composition of PLE-SEDDS was castor oil, Cremophor EL, propylene glycol, PDMSHEPMS in proportions of 31: 120: 80: 30, resp. The amount of P. ligularis extract incorporated in the formulation was 20%. The final formulation showed a 45.93 ± 1.02 nm droplet size with a PDI 0.27 ± 0.03 and zeta potential -10.92 ± 0.42 mV. Finally, in the in vivo glucose tolerance test, PLE-SEDDS improved hypoglycemic activity compared to the unformulated extract

Egelund, Peter H. G.;Jadhav, Sandip;Martin, Vincent;Johansson Castro, Henrik;Richner, Franziska;Le Quement, Sebastian Thordal;Dettner, Frank;Lechner, Carolin;Schoenleber, Ralph;Sejer Pedersen, Daniel research published 《 Fmoc-removal with pyrrolidine expands the available solvent space in green solid-phase peptide synthesis》, the research content is summarized as follows. Green binary solvent mixtures with a polarity and viscosity close to that of DMF perform similarly in solid-phase peptide synthesis (SPPS). However, while coupling reactions readily proceed in solvents of significantly lower polarity than that of DMF, a high solvent polarity is essential for Fmoc-removal (Fmoc = 9-fluorenylmethoxycarbonyl) using piperidine, which limits the options for green SPPS solvents. Herein, we report our efforts to expand the available solvent polarity space for green SPPS. We identified pyrrolidine as an efficient base to enable Fmoc-removal in less polar solvent mixtures that also favor coupling reactions, such as DMSO/ethyl acetate (1:9) and N-butylpyrrolidone/1,3-dioxolane (2:8 and 4:6). Employing less polar binary solvent mixtures in combination with pyrrolidine gave crude peptide purities comparable to or better than for DMF with piperidine in the SPPS of challenging peptide targets. An evaluation of base-dependent side reactions such as diketopiperazine (DKP) and aspartimide formation showed increased side-product formation when using pyrrolidine on DKP- and aspartimide-prone sequences. However, the scaled-up syntheses (5 and 7.5 mmol, resp.) of the peptide therapeutics dasiglucagon (29-mer) and bivalirudin (20-mer) gave good crude peptide purities and purity profiles amenable to SPPS optimization. Pyrrolidine therefore represents a useful alternative to piperidine for Fmoc-removal in an expanded solvent space for green SPPS.

Novel 1,1-diaryl vinyl-sulfones I [R = Ph, 4-MeOC₆H₄, 2,4-di-FC₆H₃, etc.] analogs of combretastatin CA-4 were synthesized via Suzuki-Miyaura coupling method and screened for in-vitro antiproliferative activity against four human cancer cell lines: MDA-MB 231(breast cancer), HeLa (cervical cancer), A549 (lung cancer), and IMR-32 (neuroblast cancer), along with a normal cell line HEK-293 (human embryonic kidney cell) by employing 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. The compounds synthesized had better cytotoxicity against the A549 and IMR-32 cell lines compared to HeLa and MDA-MB-231 cell lines. The synthesized compounds also showed significant activity on MDA-MB-231 cancer cell line with IC₅₀ of 9.85-23.94μM, and on HeLa cancer cell line with IC₅₀ of 8.39-11.70μM relative to doxorubicin having IC₅₀ values 0.89 and 1.68μM resp. for MDA-MB-231 and HeLa cell lines. All the synthesized compounds were not toxic to the growth of normal cells, HEK-293. They appeared to have a higher binding affinity for the target protein, tubulin, PDB ID = 5LYJ (beta chain), relative to the reference compounds, CA4 (- 7.1 kcal/mol) and doxorubicin (- 7.2 kcal/mol) except for I [R = 3,5-di-MeOC₆H₃, 4-ClC₆H₄, 3,4-di-ClC₆H₃, 4-NCC₆H₄]. The high binding affinity for beta-tubulin was not translated into enhanced cytotoxicity but the compounds I [R = 4-FC₆H₄, 2,4-di-FC₆H₃, 3,4-di-FC₆H₃, 4-ClC₆H₄, 3,4-di-ClC₆H₃, 2-F-5-Me-C₆H₃] that had a higher cell permeability (as predicted in-silico) demonstrated an optimum cytotoxicity against the tested cell lines in an almost uniform manner for all tested cell lines. The in-silico study provided insight into the role that cell permeability plays in enhancing the cytotoxicity of this class of compounds and as potential antiproliferative agents.

El Nashar, Nourhan F.;Sultan, Amal A.;El Maghraby, Gamal M. research published 《 Self-dispersing self-assembling systems for controlled oral delivery of gliclazide》, the research content is summarized as follows. Self-microemulsifying systems undergo self-dispersion to form microemulsion with subsequent self-assembly to form liquid crystalline (LC) and/or gel phases. These transitions modulate the release and absorption pattern of loaded drug. Accordingly, the primary objective was to evaluate these phases with respect to gliclazide release and absorption after oral administration. Pseudoternary phase diagrams were constructed using Peceol as oil, Gelucire 50/13 as surfactant and Transcutol as co-surfactant with Gelucire and Transcutol being used at 1:1 or 2:1, weight ratios. Microemulsion, LC and gel formulations were selected from these phase diagrams and were loaded with gliclazide. The selected systems were evaluated for gliclazide release which was conducted using continuous pH variation to mimic the gastrointestinal conditions. Optimum systems were subjected to in vivo evaluation. The in vivo study involved monitoring blood glucose level of diabetic rats after oral administration of gliclazide in aqueous suspension, microemulsion, LC and gel systems. Microemulsion liberated gliclazide rapidly and the rate of drug release was reduced in case of LC with further slowing in case of gel system. Interestingly, LC and gel systems liberated gliclazide steadily via zero order release kinetics. Microemulsion provided rapid reduction of blood glucose level but was not able to sustain this effect. LC and gel systems provided sustained effect and enhanced the bioavailability as shown from significant increase in the area under glucose reduction curve compared to both microemulsion and suspension form. The study thus introduced LC and gel phase as controlled release systems for oral delivery of gliclazide.

Anthocyanin, an essential ingredient of functional foods, is present in a wide range of plants, including black carrots. The current investigation was carried out to analyze the effect of cold stress on the expression of major anthocyanins and anthocyanin biosynthetic pathway genes, MYB6 and LDOX-1. Methods and results: Five cultivated carrot genotypes belonging to the eastern group, having anthocyanin pigment, were used in the current study. The qRT-PCR anal. revealed that relative gene expression of transcription factor MYB-6 and LDOX1gene was highly expressed upon cold stress compared to non-stress samples. High-performance liquid chromatog.-based quantification of Cyanidin 3–glucoside (Kuromanin chloride), Ferulic acid, 3,5-Dimethoxy-4-hydroxycinnamic acid (Sinapic acid), and Rutin revealed a significant increase in these major anthocyanins in response to cold stress when compared to control plants. Conclusion: We conclude that MYB6 and LDOX1 gene expression increases upon cold stress, which induces accumulation of major anthocyanins in purple black carrot and suggests a possible cross-link between cold stress and anthocyanin biosynthesis in purple black carrot.

Phosphodiesterase-4 (PDE4) is responsible for the selective degradation of the 3′-cyclic phosphate bonds of cAMP. A collection of twenty-three diverse 1,2,3,4-tertahydro-β-carboline- and indole-based analogs were synthesized and assessed for their inhibitory activity against human PDE4. The compounds were prepared using straightforward procedures and characterized using ¹H- and ¹³C NMR, IR, and mass spectroscopy as well as elemental anal. Fifteen of the prepared compounds exhibited significant inhibitory activity with IC₅₀ values in the lower micromolar to upper nanomolar ranges. The most active compounds also showed good selectivity for PDE4 over the related enzyme family member, PDE5, with either insignificant or null% inhibition of the latter enzyme. The indole-based compounds, 21b (I) and 21c (II), showed the most pronounced PDE4 inhibition with IC₅₀ values of 754 and 664 nM, resp. The PDE4B active site comprises both hydrophobic and solvent-filled pockets. The hydrophobic pocket (Q) includes the invariant purine-selective Gln443 which is critical for cAMP. Below this Gln443 lies Phe446 which acts as a hydrophobic P-clamp stabilizing the ligand aromatic ring system. Mol. docking investigation showed preferential anchoring of the active compounds within the PDE4 active site through interactions between the indole nitrogens and the dimethoxy Ph groups with key residues. Overall, the prepared compounds are novel and simple mols. with good potential for future optimization. Showing satisfactory predicted ADME/safety and drug-likeness properties, compound 21c is considered a promising lead for further optimization towards clin. investigation against inflammatory, auto-immune diseases, or certain types of cancer.

Microemulsion-based gels (MBGs) were prepared for transdermal delivery of lidocaine and evaluated for their potential for local anesthesia. Lidocaine solubility was measured in various oils, and phase diagrams were constructed to map the concentration range of oil, surfactant, cosurfactant, and water for oil-in-water (o/w) microemulsion (ME) domains, employing the water titration method at different surfactant/cosurfactant weight ratios. Refractive index, elec. conductivity, droplet size, zeta potential, pH, viscosity, and stability of fluid o/w MEs were evaluated. Carbomer 940 was incorporated into the fluid drug-loaded MEs as a gelling agent. Microemulsion-based gels were characterized for spreadability, pH, viscosity, and in-vitro drug release measurements, and based on the results obtained, the best MBGs were selected and subsequently subjected to ex-vivo rat skin permeation anesthetic effect and irritation studies. Data indicated the formation of nano-sized droplets of MEs ranging from 20-52 nm with a polydispersity of less than 0.5. In-vitro release and ex-vivo permeation studies on MBGs showed significantly higher drug release and permeation in comparison to the marketed topical gel. Developed MBG formulations demonstrated greater potential for transdermal delivery of lidocaine and advantage over the com. available gel product, and therefore, they may be considered as potential vehicles for the topical delivery of lidocaine.
