Small-scale culture of animal cells in suspension is of importance for many applications. At a small-scale, fed-batch is achieved either by manual bolus feeding or the use of liquid handling robots. In this study, we report an alternate application of a hydrogel for in situ continuous delivery of a nutrient feed comprising 18 amino acids, vitamins, antioxidants, and trace elements. We show that amino acid release is sustained for at least seven days. Importantly, release rates of individual amino acids can be independently modulated by changing their loading. We demonstrate the application of this hydrogel for complete in situ feeding of nutrients to a suspension adapted CHO cell line expressing IgG leading to 2.7-fold and 4-fold improvement in integral viable cell density (IVCD) and volumetric productivity respectively. This is similar to improvements obtained by bolus liquid feeding. Further, supplying glucose from the same hydrogel to eliminate manual feeding led to a 1.8-fold increase in IVCD accompanied by a 3-fold increase in volumetric productivity as compared to batch culture. In summary, this study provides a proof-of-concept that hydrogels can enable completely closed in situ feeding for mammalian cell culture requiring no external intervention. Such continuous in situ delivery can potentially enable closed culture systems maintaining nutrients at low levels mimicking physiological concentrations.

High-throughput screening has shown that Retro-1 inhibits ricin and Shiga toxins by diminishing their intracellular trafficking via the retrograde route, from early endosomes to the Golgi apparatus. To improve the activity of Retro-1, a structure-activity relationship (SAR) study was undertaken and yielded an analogue with a roughly 70-fold better half-maximal effective concentration (EC50) against Shiga toxin cytotoxicity measured in a cell protein synthesis assay.

An efficient, reusable and stable binaphthyl stabilized Pd-nanoparticles (Pd-BNP) catalyzed the direct ortho-C-H hydroxylation of acetophenone oxime ethers under neutral and phosphine ligand-free condition has been developed. A readily available, economic, safe and greener oxidant oxone has been used in this direct ortho-hydroxylation. The scope of the reaction has been studied with various acetophenone oxime ethers including electron rich to electron deficient system and the reaction afforded only mono hydroxylated products in a highly regioselective manner. Several control experiment results confirmed that the oxone is the hydroxyl source. The Pd-BNP catalyst has been reused up to five times. The heterogeneous test confirmed that the reaction is catalyzed by the heterogeneous Pd-BNP catalyst.

Purpose: We investigated Nw-hydroxy L-Arginine (NOHA) predictive response in serous ovarian carcinoma based on estrogen-hormone receptor expression status; and assessed the distinctive NOHA response between estrogen-receptor-negative (ER-) tumor subtypes of ovarian and breast cancer. Materials/methods: Three-dimensional (3D) spheroids models of ER- and estrogen-receptor-positive (ER+) from breast and ovarian tumor, cultured for 9 weeks, were assayed for cellular levels of inducible nitric oxide synthase (NOS2), nitric oxide (as total nitrite) and L-Arginine, and compared to NOHA in culture medium. Statistical difference was set at p < 0.01. Results: Nine-week in vitro studies showed a progressive NOHA reduction in culture medium by at least 0.4-0.8 fold, and 0.65-0.92 fold only in the ER-breast tumor and ER-ovarian tumor 3D spheroids, respectively; with increases in cellular NOS2 and nitric-oxide levels, by at least 1.0-2.45 fold in both ER-tumor subtype 3D spheroids (p < 0.01; n = 6). Within ER-subtypes, medium NOHA decreased by >= 38.9% in ovarian cancer over breast cancer 3D-spheroids, with cellular increases in NOS2 (by >= 17.4%), and nitric oxide (by >= 18.8%). Cellular L-Arginine to medium NOHA ratio was higher, and by at least 6.5-22.5 fold in ER-breast tumor 3D-spheroids, and at least 10-70 fold in ER-ovarian tumor 3D spheroids, than in ER+ and control conditions; and was >= 48% higher in ER-ovarian cancer than in ER-breast cancer 3D-spheroids. Conclusions: The present study shows NOHA as a sensitive and selective indicator differentiating and distinguishing ER-subtypes based on the tumor grade.

A new Schiff base receptor (2-amino-3-(((3-hydroxy-5-(hydroxymethyl)-2-methylpyridin-4-yl)methylene) amino)maleonitrile (GAL)) has been synthesized and such diaminomaleonitrile-based molecular framework is observed to be water soluble. GAL possesses both colorimetric and off-on fluorescent response in the presence of ClO-. The response time has been controlled within 6 min. The limit of detection (LOD) has been calculated to be 47.5 nM. The addition of Cu2+ can only induce clear color evolution from pale to deep yellow (LOD: 0.22 mu M) and no fluorescence changes are found. Moreover, its reliability and practicality are verified via the determination of ClO- in spiked samples of tap water and pond water. The exploration of bioactive vitamin B6 cofactor as a sensing platform will open a new way for multiple target recognition in competitive mediums. (C) 2020 Elsevier B.V. All rights reserved.

Functionalization with C1-building blocks are key synthetic methods in organic synthesis. The low reactivity of the most abundant C-1-molecule, carbon dioxide, makes alternative carboxylation reactions with CO2-surrogates especially important. We report a photoredox-catalyzed protocol for alkene carbamoylations. Readily accessible 4-carboxamido-Hantzsch esters serve as convenient starting materials that generate carbamoyl radicals upon visible light-mediated single-electron transfer. Addition to various alkenes proceeded with high levels of regio- and chemoselectivity.

Human 15-lipoxygenase-1 (15-LOX-1) belongs to the class of lipoxygenases, which catalyze oxygenation of polyunsaturated fatty acids, such as arachidonic and linoleic acid. Recent studies have shown that 15-LOX-1 plays an important role in physiological processes linked to several diseases such as airway inflammation disease, coronary artery disease, and several types of cancer such as rectal, colon, breast and prostate cancer. In this study, we aimed to extend the structural diversity of 15-LOX-1 inhibitors, starting from the recently identified indolyl core. In order to find new scaffolds, we employed a combinatorial approach using various aromatic aldehydes and an aliphatic hydrazide tail. This scaffold-hopping study resulted in the identification of the 3-pyridylring as a suitable replacement of the indolyl core with an inhibitory activity in the micromolar range (IC50=16 +/- 6m) and a rapid and efficient structure-activity relationship investigation.

The anti-selective direct asymmetric Mannich reaction of (hetero) aromatic aldehydes, 4-anisidine and O-protected hydroxyacetones for the synthesis of stereodefined anti-beta-amino-alpha-hydroxycarbonyl compounds was developed. Protease type XIV from Streptomyces griseus (SGP) was used as a biocatalyst in 1,4-dioxane/phosphate buffer under mild reaction conditions. The excellent diastereoselectivities of up to >99:1 (anti/syn) and good enantioselectivities of up to 90% ee were achieved. This method provides a more sustainable complement to chemically catalyzed anti-selective direct asymmetric Mannich reactions. (C) 2019 Elsevier Ltd. All rights reserved.
