Divya, Indira S.; Amrutha, Surendran; SeethaLekshmi, Sunil; Varughese, Sunil published the artcile< Molecular salts of quinine: a crystal engineering route to enhance the aqueous solubility>, Category: alcohols-buliding-blocks, the main research area is quinine mol salt crystal engineering aqueous solubility.

The antimalarial drug quinine (QUN) has poor aqueous solubility and belongs to Biopharmaceutical Classification System (BCS) Class-II. We report 12 novel mol. salts of QUN with α,ω-aliphatic dicarboxylic acids and aromatic coformers. The high basicity of QUN and ΔpKa of ~5 make the complexes ionic, and most of them are hydrates. The solid forms showed enhanced aqueous solubility compared to the pristine QUN. The single-crystal and powder X-ray diffraction, thermal, and microscopy data provide structural, compositional, and stability profiles of the salts. The calculated Full Interaction Maps (FIMs) provide statistical insights into the salt formation and high probability of hydration in QUN. Though with prospective torsional freedom, QUN in most complexes adopts a unique conformation; this indicates that the structure class has a higher statistical probability and belongs to a relatively deep potential energy trough in the vast crystal landscape.

Abdelgawad, Ibrahim Y.; Grant, Marianne K. O.; Zordoky, Beshay N. published the artcile< Leveraging the cardio-protective and anticancer properties of resveratrol in cardio-oncology>, SDS of cas: 501-36-0 , the main research area is review cardioncol cardiprotection resveratrol anticancer; anthracycline; cancer; cardio-oncology; cardiotoxicity; cardiovascular; resveratrol.

A review. Cardio-oncol. is a clin./scientific discipline which aims to prevent and/or treat cardiovascular diseases in cancer patients. Although a large number of cancer treatments are known to cause cardiovascular toxicity, they are still widely used because they are highly effective. Unfortunately, therapeutic interventions to prevent and/or treat cancer treatment-induced cardiovascular toxicity have not been established yet. A major challenge for such interventions is to protect the cardiovascular system without compromising the therapeutic benefit of anticancer medications. Intriguingly, the polyphenolic natural compound resveratrol and its analogs have been shown in preclin. studies to protect against cancer treatment-induced cardiovascular toxicity. They have also been shown to possess significant anticancer properties on their own, and to enhance the anticancer effect of other cancer treatments. Thus, they hold significant promise to protect the cardiovascular system and fight the cancer at the same time. In this review, we will discuss the current knowledge regarding the cardio-protective and the anticancer properties of resveratrol and its analogs. Thereafter, we will discuss the challenges that face the clin. application of these agents. To conclude, we will highlight important gaps of knowledge and future research directions to accelerate the translation of these exciting preclin. findings to cancer patient care.

The functionalized 3,4-dihydroquinolin-2-ones I (R1 = Me, 4-MeOC6H4CH2, 4-BrC6H4CH2, 4-MeSC6H4CH2, 2-furylmethyl; R2 = H, Cl; R3 = H, Me, MeO; R4 = H, CF3) have been assembled in good to high yields through the sequential reaction of readily available N-Ts-o-aminobenzyl alcs. II with 5-R1-substituted Meldrum’s acids under mild basic conditions. Highly diastereoselective synthesis of trans-3-R1-4-phenyl-1-tosyl-3,4-dihydroquinolin-2(1H)-ones was accomplished from 2-(tosylamino)-α-phenylbenzenemethanol under the same reaction conditions. Regarding the reaction mechanism, the formation of dihydroquinolones proceeds through the in situ generation of aza-o-QMs followed by conjugate addition of enolate/cyclization/elimination of acetone and CO2.

Lim, Bumhee; Lee, Jinah; Kim, Byungjin; Lee, Rang; Park, Jaehyun; Oh, Dong-Chan; Gam, Jongsik; Lee, Jeeyeon published the artcile< Target Identification of a 1,3,4-Oxadiazin-5(6H)-One Anticancer Agent via Photoaffinity Labelling>, Application In Synthesis of 25055-82-7, the main research area is oxadiazinone protein anticancer agent photoaffinity labeling probe.

Rational design and synthetic feasibility are critical factors for the photoaffinity labeling (PAL) approach, which can identify protein targets of bioactive small mols. under native cellular conditions. In this study, we developed photoaffinity labeling probes derived from 1,3,4-oxadiazin-5(6H)-ones (OPALs) for LL-2003, a previously reported potential anticancer agent against IGF-1R and Src. Our photoaffinity labeling strategy enabled successful photo-crosslinking of the probes (OPAL-6 and OPAL-8) with the target proteins in both mammalian cell lysates and live MCF7, A549, HepG2 and HeLa cells in situ. In vitro and in situ labeling demonstrated different patterns and expression levels of the proteome, and the strongest band for Src appeared in the A549 cell line. An in-gel fluorescence scan combined with MS/MS anal. of the IGF-1R overexpressed insect proteome labeled by OPAL-6 and OPAL-8 identified the binding location of the synthesized probes.

Carr, Georgina; Haslam, Iain S.; Simmons, Nicholas L. published the artcile< Voltage Dependence of Transepithelial Guanidine Permeation Across Caco-2 Epithelia Allows Determination of the Paracellular Flux Component>, COA of Formula: C7H18ClNO5, the main research area is guanidine organic cation paracellular permeation intestine Caco2 cell.

The aim of this study was to investigate transepithelial ionic permeation via the paracellular pathway of human Caco-2 epithelial monolayers and its contribution to absorption of the base guanidine. Confluent monolayers of Caco-2 epithelial cells were mounted in Ussing chambers and the transepithelial conductance and elec. p.d. determined after NaCl dilution or medium Na substitution (bi-ionic conditions). Guanidine absorption (Ja-b) was measured ± transepithelial potential gradients using bi-ionic p.d.’s. Basal NaCl replacement with mannitol gives a transepithelial dilution p.d. of 28.0 ± 3.1 mV basal solution electropos. (PCl/PNa = 0.34). Bi-ionic p.d.’s (basal replacements) indicate a cation selectivity of NH4+ > K+∼Cs+ > Na+ > Li+ > tetraethylammonium+ > N-methyl-d-glucamine+∼choline+. Transepithelial conductances show good correspondence with bi-ionic potential data. Guanidine Ja-b was markedly sensitive to imposed transepithelial p.d. The ratio of guanidine to mannitol permeability (measured simultaneously) increased from 3.6 in the absence of an imposed p.d. to 13.8 (basolateral neg. p.d.). Hydrated monovalent ions preferentially permeate the paracellular pathway (Eisenman sequence 2 or 3). Guanidine may access the paracellular pathway because absorptive flux is sensitive to the transepithelial p.d. An alternative method to assess paracellular-mediated flux of charged organic mols. is suggested.

Zhang, Yunqin; He, Haiqing; Chen, Zixi; Huang, Yingying; Xiang, Guisheng; Li, Penghua; Yang, Xingkuan; Lu, Gang; Xiao, Guozhi published the artcile< Merging Reagent Modulation and Remote Anchimeric Assistance for Glycosylation: Highly Stereoselective Synthesis of α-Glycans up to a 30-mer>, SDS of cas: 4064-06-6, the main research area is branched oligosaccharide preparation glycosylation reagent modulation anchimeric assistance; 1,2-cis glycosylation; reagent modulation; remote anchimeric assistance; structure elucidation; synthetic methods.

The efficient synthesis of long, branched, and complex carbohydrates containing multiple 1,2-cis glycosidic linkages is a long-standing challenge. Here, we report a merging reagent modulation and 6-O-levulinoyl remote anchimeric assistance glycosylation strategy, which is successfully applied to the first highly stereoselective synthesis of the branched Dendrobium Huoshanense glycans and the linear Longan glycans containing up to 30 contiguous 1,2-cis glucosidic bonds. DFT calculations shed light on the origin of the much higher stereoselectivities of 1,2-cis glucosylation with 6-O-levulinoyl group than 6-O-acetyl or 6-O-benzoyl groups. Orthogonal one-pot glycosylation strategy based on glycosyl ortho-alkynylbenzoates and ortho-(1-phenylvinyl)benzoates has been demonstrated in the efficient synthesis of complex glycans, precluding such issues as aglycon transfer inherent to orthogonal one-pot synthesis based on thioglycosides.

Authors describe a catalytic strategy for direct single C(sp3)-F bond alkylation of trifluoromethylbenzimidazoles under a photoinduced thiol-catalysis process. The CO2 radical anion (CO2·-) was proven the efficient single electron reductant to realize such transformation. The spin-center shift of the generated radical anion intermediate is the key step to realize the C-F bond activation in mild conditions with high efficiency.

Hydrazones have been employed as the starting materials in a KOH-mediated one-pot three-component cycloaddition with readily accessible nitroso compounds and olefins to construct various isoxazolidines. Compared with diazo compounds as starting materials, this methodol. could afford a wider range of products in good to excellent yields and diastereoselectivities for most substrates, and hydrazones are cheaper, more accessible, and safer substrates. The exptl. study shows that the choice of suitable hydrazones is crucial.
