Hypoactive sexual desire disorder (HSDD) is one of the most common sexual complaints in women. Currently, there is an unmet need for a drug treatment for this disorder. The purpose of this study was to develop a testosterone (TS) film forming gel used for women to treat HSDD by measuring the tackiness, peel adhesion force, tensile strength, and elasticity of the formulation. Diethylene glycol monoethyl ether (Transcutol P), an efficient penetration enhancer, was added to the optimized formulation and the transdermal permeation characteristics in vitro were studied using Franz-diffusion cells. The quant. determination of TS was performed by high-performance liquid chromatog. (HPLC). After 24 h, Transcutol P at 3% had the largest cumulative amount of drug and enhancement ratio of TS of 75.14μg/cm2 and 2.82, resp. After the screening of film forming polymers and penetration enhancers, the optimal formulation was as follows: glycerol (1%, weight/weight); 12.5% sodium CM-cellulose (CMC-Na) aqueous solution (0.5%, weight/weight); 2.5% Carbomer ethanol solution (0.5%, weight/weight); Transcutol P ethanol solution (3%, weight/weight) containing 0.5% TS; and 8% Poly vinyl alc. (PVA) aqueous solution (30%, weight/weight). The optimized film forming gel had good uniformity and the release of TS in vitro was close to 100% within 24 h. In vivo studies showed the formulations had optimal area under blood drug concentration curve values in the order of 3% Transcutol P > 1% Transcutol P > 5% Transcutol P > control preparation The formulation with 3% Transcutol P provided the highest permeation effect both in vitro and in vivo. The safety of this formulation was further evaluated with a skin irritation test. It could effectively improve the rabbit skin irritation observed with a marketed transdermal patch Androderm. The present study provides a promising approach for the development of a novel TS film forming gel for the treatment of HSDD in women.

Solubility and thermodn. properties of lamotrigine as a practically insoluble drug in binary mixtures of choline chloride / propylene glycol deep eutectic solvent and water are determined by shake-flask method followed by a spectrophotometric method at the temperature range of 293.2-313.2 K. The acquired molar data are correlated to the linear and non-linear solubility models including van’t Hoff, the mixture response surface, the Jouyban-Acree, the Jouyban-Acree-van’t Hoff, the modified Wilson and the λh equations. The accuracy of each model is tested by the mean relative deviation of the back-calculated solubility data. Moreover, the apparent thermodn. properties of lamotrigine dissolution are also calculated based on the van’t Hoff and Gibbs equations.

Zannou, Oscar;Pashazadeh, Hojjat;Ibrahim, Salam A.;Koca, Ilkay;Galanakis, Charis M. research published 《 Green and highly extraction of phenolic compounds and antioxidant capacity from kinkeliba (Combretum micranthum G. Don) by natural deep eutectic solvents (NADESs) using maceration, ultrasound-assisted extraction and homogenate-assisted extraction》, the research content is summarized as follows. Kinkeliba (C. micranthum) is a tropical plant widely used for its tremendous phytochems. and biol. activities. In the present study, three green carboxylic acid-based natural deep eutectic solvents (NADESs) were used to assess the extraction of phenolic compounds in terms of total phenolic content (TPC), total flavonoid content (TFC), individual phenolic compounds and antioxidant capacity (DPPH and FRAP assays) from dried C. micranthum leaves. For the synthesis of NADESs choline chloride was used as hydrogen bond acceptors (HBA) in combination with lactic acid (ChLa), acetic acid (ChAa) and tartaric acid (ChTa) as hydrogen bond donors (HBDs). The conventional solvents including distilled water, pure methanol and pure ethanol were used for comparison. Three extraction methods including maceration extraction (ME), homogenate-assisted extraction (HAE) and ultrasound-assisted extraction (UAE) were tested to determine the best extraction conditions. The solvents combined with the extraction methods were successfully applied for the recovery of phenolic compounds from C. micranthum leaves. ChLa exhibited the highest performance giving the TPC (21.12 ± 0.13-23.62 ± 0.58 mg GAE/g), followed by ChAc (15.49 ± 0.13-18.85 ± 0.39 mg GAE/g), water (17.08 ± 0.32-18.13 ± 0.13 mg GAE/g), ChTa (14.49 ± 0.26-17.44 ± 0.19 mg GAE/g), methanol (7.46 ± 0.45-11.64 ± 0.32 mg GAE/g) and ethanol (2.88 ± 0.39-4.60 ± 0.39 mg GAE/g), resp. For TFC, ChLa (4.38 ± 0.09-5.01 ± 0.09 mg ECE/g) was the most prominent solvent, followed by ChAc (2.84 ± 0.04-5.01 ± 0.36 mg ECE/g), methanol (1.93 ± 053-4.85 ± 0.04 mg ECE/g), ethanol (1.49 ± 0.36-4.16 ± 0.04 mg ECE/g), ChTa (1.09 ± 0.04-3.22 ± 0.13 mg ECE/g) and water (1.15 ± 0.04-1.37 ± 0.44 mg ECE/g), resp. The acidic NADESs especially ChLa and ChAa exhibited the best efficiencies compared to the conventional solvents. Furthermore, UAE and HAE provided good extraction efficiency in a short extraction time (30 min) in terms of the TPC, TFC, individual phenolic compounds and the antioxidant capacity compared to ME which gave a similar yield with 12 h of extraction time. Principal component anal. (PCA) showed that C. micranthum extracts could clearly be discriminated in terms of phytochem. compounds and antioxidant capacity and UAE, HAE or ME combined with ChLa ChAc or ChTa were the best choices to higher extraction efficiency.

Yu, Cheng-wei;Luo, Ting;Xie, Tian;Li, Jing;Deng, Ze-yuan research published 《 Classified processing of different rice bran fractions according to their component distributions》, the research content is summarized as follows. Rice grains were obtained from two Chinese provinces (Hubei and Guangxi) and then their rice bran was abraded into four equal fractions by weight from outside to inside. The component distributions in these four fractions were then investigated. The contents of total lipid-soluble antioxidant showed no significant difference between rice bran from the Hubei province and the Guangxi province. But the content of total water-soluble antioxidant was 1690.20 ± 86.40 mg kg-1 for rice bran from the Hubei province, significantly higher than those from the Guangxi province (1014.67 ± 71.09 mg kg-1). Obvious differences between four rice bran fractions or two provinces were proved by principal component anal. (PCA). Lipase activities decreased significantly from outer fractions to inner fractions, and lipids mainly distributed in three outer fractions. The essential element contents decreased significantly, but a main heavy metal element (Pb) in cereal increased significantly to 0.36 mg kg-1 from outer fractions to inner fractions, which was just slightly below the upper limit of Chinese Standard (0.40 mg kg-1). Although protein contents had no significant difference in four fractions, the amino acid compositions were quite different. In summary, different fractions of rice bran had different compositions, which could provide guidance for the classified processing of rice bran.

The circadian rhythm of aquatic animals has been a subject of research in a diverse range of studies. However, research on the circadian rhythm of the economically important crustacean Eriocheir sinensis is scarce although this species exhibits an obvious circadian rhythm. In this study, we applied liquid chromatog.-mass spectrometry-based metabolomics to identify key metabolites in the hepatopancreas of E. sinensis under the 24-h circadian rhythm. Through comparative anal. of the metabolites obtained at different time points (06:00 vs. 12:00 h, 06:00 vs. 18:00 h, and 06:00 vs. 24:00 h), 431 differentially expressed metabolites were identified and classified. The Kyoto Encyclopedia of Genes and Genomes pathway anal. showed that the differentially expressed metabolites were enriched in some circadian rhythm-related pathways, especially metabolic pathways related to nutrient digestion and absorption. Moreover, several pathways with high impact factors such as “Intestinal immune network for IgA production” were identified, and their functions were mostly related to immunity. This is the first study to identify the metabolites in the hepatopancreas of a crustacean through metabolomic anal. It provides novel insights into the circadian rhythm of E. sinensis, which could benefit its culture and further increase its economic value.

Peptides have potential to be developed into immune checkpoint inhibitors, but the target interfaces are difficult to inhibit. Here, we explored an approach to mimic the binding surface of PD-1 to design inhibitors. Mimicking native PD-1 resulted in a mimetic with no activity. However, mimicking an affinity-optimized PD-1 resulted in the peptide mimetic MOPD-1 that displayed nanomolar affinity to PD-L1 and could inhibit PD-1:PD-L1 interactions in both protein- and cell-based assays. Mutagenesis and structural characterization using NMR spectroscopy and X-ray crystallog. revealed that binding residues from the high affinity PD-1 are crucial for the bioactivity of MOPD-1. Furthermore, MOPD-1 was extremely stable in human serum and inhibited tumor growth in vivo, suggesting it has potential for use in cancer immunotherapy. The successful design of an inhibitor of PD-1:PD-L1 using the mimicry approach described herein illustrates the value of placing greater emphasis on optimizing the target interface before inhibitor design and is an approach that could have broader utility for the design of peptide inhibitors for other complex protein-protein interactions.

Ethers can again be classified into two varieties: if the alkyl or aryl groups are the same on both sides of the oxygen atom, 73724-45-5, formula is C18H17NO5, Name is Fmoc-Ser-OH. Then it is a simple or symmetrical ether, whereas if they are different, the ethers are called mixed or unsymmetrical ethers. Related Products of 73724-45-5.

Yao, Guiyang;Knittel, Caroline H.;Kosol, Simone;Wenz, Marius T.;Keller, Bettina G.;Gruss, Hendrik;Braun, Alexandra C.;Lutz, Christian;Hechler, Torsten;Pahl, Andreas;Suessmuth, Roderich D. research published 《 Iodine-mediated tryptathionine formation facilitates the synthesis of amanitins》, the research content is summarized as follows. Synthetic methods on the macrocyclization of peptides are of high interest since they facilitate the synthesis of various types of potentially bioactive compounds, e.g. addressing targets like protein-protein-interactions. Herein, we report on an efficient method to construct tryptathionine-cross-links in peptides between the amino acids Trp and Cys. This reaction not only is the basis for the total synthesis of the death cap toxin α-amanitin but also provides rapid access to various new amanitin analogs. This study for the first time presents a systematic compilation of structure-activity relations (SAR) of amatoxins with regard to RNA polymerase II inhibition and cytotoxicity with one amanitin derivative of superior RNAP II inhibition. The present approach paves the way for the synthesis of structurally diverse amatoxins as future payloads for antibody-toxin conjugates in cancer therapy.

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., Related Products of 73724-45-5
