Soerensen, Kasper K.;Mishra, Narendra K.;Paprocki, Maciej P.;Mehrotra, Amit;Jensen, Knud J. research published 《 High-Performance Reversed-Phase Flash Chromatography Purification of Peptides and Chemically Modified Insulins》, the research content is summarized as follows. Preparative reversed-phase HPLC is the established method for the purification of peptides, but has significant limitations. We systematically investigated the use of high-performance reversed-phase flash chromatog. (HPFC) to rapidly purify laboratory-scale quantities of crude, synthetic peptides and chem. modified insulins. We demonstrated these methods for a diverse set of peptides, including short, medium, and long peptides. Depending on the purity profile of the peptide, HPFC can be used either as the sole purification method, or as a pre-purification method prior to final HPLC purification Furthermore, HPFC is suitable for the purification of peptides that are not fully in solution We provide guidelines for the HPFC of synthetic peptides and small proteins, including the choice of columns, eluents, and gradients. We believe that HPFC is a valuable alternative to HPLC purification of peptides and small proteins.

Smolen, Sylwester;Kowalska, Iwona;Skoczylas, Lukasz;Tabaszewska, Malgorzata;Pitala, Joanna;Mrozek, Joanna;Kovacik, Peter research published 《 Effectiveness of enriching lettuce with iodine using 5-iodosalicylic and 3,5-diiodosalicylic acids and the chemical composition of plants depending on the type of soil in a pot experiment》, the research content is summarized as follows. Iodine is a beneficial element for humans, animals and plants. This study was a comparison of the effectiveness of iodosalicylate uptake by lettuce. The experiment included two sub-blocks: organic soil and mineral soil with the addition of the same fertigation of plants (8 times every 7 days) with 10 μM solutions (100 mL/per one plant/one application) of potassium iodate (KIO3), salicylic acid (SA) alone or together with KIO3, 5-iodosalicylic acid (5-ISA) or 3,5-diiodosalicylic acid (3,5-diISA). None of the tested iodine compounds neg. affected the yield of lettuce. When growing plants on mineral soil, plants accumulated more iodine in the leaves than plants grown on peat substrate. The use of 5-ISA allowed for achieving better efficiency of plant biofortification in iodine than the application of KIO3 and 3,5-diISA. The type of soil significantly modified the chem. composition of lettuce.

Skiba, Margarita;Vorobyova, Victoria research published 《 Green synthesis and characterization of silver nanoparticles using Prunus persica L. (peach pomace) with natural deep eutectic solvent and plasma-liquid process》, the research content is summarized as follows. This study reports two different innovation “green” protocols for the extraction of fruit waste peach pomace (PP) and subsequent synthesis of silver nanoparticles that were used. In one case, extraction of PP was performed using natural ionic solvent (lactic acid, glucose, and water (5:1:3 molar ratio)) with the following chem. synthesis of the AgNPs in the second step. In the second case, a one-step extraction/synthesis of silver nanoparticles under a short-term (5-10 min) plasma-liquid atm. discharge process was used. Various techniques used to characterize synthesized nanoparticles are SAED, SEM, TEM, and UV-visible spectrophotometer. It was found that for both methods, the hydromodule (ratio of raw materials to solvent) is one of the main factors that determines the absorption spectra and particle size of the synthesized AgNPs. The simultaneously plasma chem.-assisted extraction and synthesis NPs protocol with hydromodule ∼ [1]:[10] ÷ [1]:[60] provides the formation surface plasmon resonance (SPR) of absorption spectra at 420-430 nm with average size of NPs 15-27 nm for 1 min of processing; λmax = 550-570 nm, λmax = 670 nm with average size of NPs 100-150 nm. NADES-assisted extraction and synthesis NPs with hydromodule ∼ [1]:[20] ÷ [1]:[45] provides SPR at 405-430 nm with average size of NPs 10-20 nm. It was established that plasma-assisted extraction provides a greater degree of extraction total phenolic content (TPC) compared to NADES extraction As a consequence, it provides correspondingly higher indicators of antioxidant activity of plasma-synthesized silver nanoparticles (IC50 of 0.81-1.33 mg/mL, DPPH at 2.5 mg/mL was: 73-88% for AgNPs). In return NADES extraction provides higher antimicrobial and catalytic activity of the AgNPs because they are depended by the average size of nanoparticles, which are much smaller in the synthesis of this method. The AgNPs showed antimicrobial activity against pathogenic Escherichia coli, Staphylococcus aureus, and Candida albicans antimicrobial activity in low concentrations (23-36 nM).

Sinico, Chiara;Fadda, Anna Maria;Valenti, Donatella;Pireddu, Rosa;Corrias, Francesco;Schlich, Michele;Pitzanti, Giulia;Lai, Francesco research published 《 Nanoliposomes@Transcutol for in vitro skin delivery of 8-methoxypsoralen》, the research content is summarized as follows. The 8-methoxypsoralen is the most common drug in psoralen plus UV light irradiation therapy for the treatment of severe psoriasis. Despite of the efficacy, its classic oral administration leads to several serious adverse effects. However, the topical psoralen application produces a drug skin accumulation lower than that obtained by oral administration, due to the drug low skin permeability. In this paper, 8-methoxypsoralen loaded Penetration Enhancer-contg Vesicles were prepared using soy phosphatidylcholine and the penetration enhancer Transcutol (5% or 10%) and characterized in terms of size, polydispersity index, zeta potential and encapsulation efficiency. No statistically significant differences in both size (∼135 nm) and encapsulation efficiency (∼65%) were found for different Transcutol concentration Transdermal delivery study assessed by Franz diffusion cells, showed that the 8-methoxypsoralen mainly accumulated into the stratum corneum. Moreover, after Penetration Enhancer-contg Vesicles application, the drug recovered in this layer is almost double of that delivered by conventional liposomes, while no significant difference was found from the different Transcutol concentrations Finally, biocompatibility checked by an MTT assay, demonstrated that the incubation of human keratinocytes for 24 h with 8-methoxypsoralen loaded Penetration Enhancer-contg Vesicles did not significantly reduce cell viability.

Singha, L. Ronibala;Das, Malay K. research published 《 Effect of Mesua ferrea Linn. seed kernel oil on percutaneous absorption of Diltiazem hydrochloride through pig ear epidermis: A mechanistic study》, the research content is summarized as follows. The present study reports the mechanistic investigation on Mesua ferrea L. seed kernel oil as a natural skin permeation enhancer. The natural oil was extracted by Soxhlation method. The permeation parameters resulting from the ex vivo skin permeation study of the model drug Diltiazem HCl across oil pre-treated pig ear epidermis revealed better transdermal flux of the test groups compared to the control one. Also, the investigated oil exhibited significantly higher penetration enhancement effect compared to the standard penetration enhancer Transcutol and the maximum permeation enhancement effect was observed at 15% volume/volume in PG. The permeation enhancement mechanistic studies by FT-IR, DSC and SEM suggested that the enhancement effect of the oil was due to the fluidization of lipids and interaction with keratinocytes of the stratum corneum maintaining morphol. integrity of the skin membrane. Furthermore, the test oil was found to be non-irritant in nature and safe for topical application. These findings suggests the Mesua ferrea L. seed oil is an efficient and safe natural skin permeation enhancer providing the scope for future research on its usage in the development of transdermal drug delivery devices.

Singh, Tej Pratap;Ahmad, Farhan Jalees;Jain, Gaurav Kumar;Verma, Navneet research published 《 Formulation development and characterization of nanoemulsion-based gel for topical application of raloxifene hydrochloride》, the research content is summarized as follows. Nanoemulsion-gels are nanosized droplets, and thermodynamically stable oil-in-water dispersion. Raloxifene hydrochloride a selective estrogen receptor modulator currently its more research is being laid on in treatment of diseases in estrogen deficient postmenopausal women. The objective of this research was to formulate nanoemulsion-gel of raloxifene for topical delivery. The oil, surfactant and cosurfactant were selected on the basis of maximal solubility of raloxifene. The screening of surfactant and cosurfactant were on the basis of their emulsification efficacy with oil to form homogenization mixture on gentle shaking. The nanoemulsions were prepared by ternary phase diagram method using different ratio of oil and surfactant-cosurfactant mixture (Smix) and nanoemulsion region obtained by excel sheet design triangular software. The composition of the optimized nanoemulsion contains 0.072 %w/v raloxifene, 14.29 %volume/volume oil phase (Labrafil-M2125CS), 33.33%volume/volume Smix (Cremophor-RH40:Transcutol-P, 1:1), and 52.38%volume/volume distilled water. The optimized nanoemulsion was converted into gel form by addition of 1%w/v Carbopol-934. The formulation NEG2 possessed droplets size 56.73±0.58 nm, zeta-potential -22.20±0.02 mV, spreadability 18.35±0.45 gcm-1sec-1 and viscosity 98.54 ± 0.39 mPas. The ex vivo permeation of NEG2 (22.38%) was comparatively lower to the permeation of NE3 (26.68%). Also, flux of NEG2 (11.96 ± 0.4 μgcm-2h-1) significantly lower permeability than NE3(16.28 ± 0.7μgcm-2h-1). But nanoemulsion-gel form is maintained more effective concentration within skin due to adhesive nature of gel form remain contact on the applied area for a long duration. Nanoemulsion-gel found stable during six months. The outcome of this study points out the nanoemulsion-gel better than nanoemulsion because of adhesive nature and less permeability. Consequently, It maintain more raloxifene concentration at applied skin.

Supersaturable SMEDDS, a versatile dosage form, was investigated for improving the biopharmaceutical attributes and eradicating the food effect of poorly water soluble drug efavirenz. The present research pursues the development of efavirenz loaded Supersaturable Self- Microemulsifying Drug Delivery System (SS SMEDDS) for improving biopharmaceutical performance. Preformulation studies were carried out to determine the optimized range of lipid excipients to develop stable supersaturated SMEDDS (ST SMEDDS). The SS SMEDD formulation was prepared by adding hydroxypropyl methylcellulose as a polymeric precipitation inhibitor. The developed SS SMEDDS were evaluated for supersaturation behavior by performing in vitro supersaturation studies and mol. simulations by in silico docking. Dissolution was performed in biorelevant media to simulate fed/fasted conditions in gastrointestinal regions. Absorption behavior was determined through in vivo pharmacokinetics approach. The optimized ST SMEDDS formulation containing Maisine CC, Tween 80 and Transcutol-P exhibited thermodn. stability with quick rate of emulsification. The optimized SS SMEDDS containing suitable polymeric precipitation inhibitor exhibited enhanced efavirenz concentration in in vitro supersaturation test. The theor. simulations by mol. docking revealed strong intermol. interactions with a docking score of -3.004 KJ/mol. The dissolution performance of marketed product in biorelevant dissolution media inferred the existence of food effect in the dissolution of efavirenz. However, in SS SMEDDS, no significant differences in drug release behavior under different fasted/fed conditions signify that the food effect was neutralized. In vivo pharmacokinetics revealed a significant increase in the absorption profile of efavirenz from SS SMEDDS than that of ST SMEDDS and marketed product. The designed delivery system indicated promising results in developing an effectual EFV formulation for HIV treatment.

Herein we describe the design of a novel and high-confidence homol. model to guide a medicinal chem. effort that resulted in the discovery of a series of peptides that demonstrate high affinity, selective binding to the Antioxidant Response Element (ARE) DNA and thereby displace NRF2-MAFG from its promoter, which is an inhibitory mechanism that to our knowledge has not been previously described. In addition to their activity in electrophoretic mobility shift (EMSA) and TR-FRET-based assays, we show significant dose-dependent ternary complex disruption of NRF2-MAFG binding to DNA by SPR, as well as cellular target engagement by thermal destabilization of HiBiT-tagged NRF2 in the NCI-H1944 NSCLC cell line upon digitonin permeabilization, and SAR studies leading to improved cellular stability. We report the characterization and unique profile of lead peptide (1), [(Ac-DELRAKALHIPFPVEKIINLPVVDFNEMMSKEQFN-EAQLALIRDIRRRGKNKVAAQNSRKRKLENIVELEQDLDHLKDEKEKGGhPraA-GSSG-K(DBCO-Cy5)-CONH₂)-(Ac-NGTSLTDEELVTMSVRELNQHLRGLSKEEIVQLKQRRRTLKNRGYAASSRVKRVTQKEELEKQKAELQQEVEKGGDabA-CONH₂)] which we believe to be a useful in vitro tool to probe NRF2 biol. in cancer cell lines and models, while also serving as an excellent starting point for addnl. in vivo optimization toward inhibition of NRF2-driven transcription to address a significant unmet medical need in non-small cell lung cancer (NSCLC).

73724-45-5, Fmoc-Ser-OH, also known as Fmoc-Ser-OH, is a useful research compound. Its molecular formula is C18H17NO5 and its molecular weight is 327.3 g/mol. The purity is usually 95%.
Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., HPLC of Formula: 73724-45-5
