Siddiqui, Farid A. published the artcilePDE6D Inhibitors with a New Design Principle Selectively Block K-Ras Activity, Formula: C9H5ClO4S, the publication is ACS Omega (2020), 5(1), 832-842, database is CAplus and MEDLINE.

The trafficking chaperone PDE6D (also referred to as PDEδ) has been nominated as a surrogate target for K-Ras4B (hereafter K-Ras). Arl2-assisted unloading of K-Ras from PDE6D in the perinuclear area is significant for correct K-Ras localization and therefore activity. However, the unloading mechanism also leads to the undesired ejection of PDE6D inhibitors. To counteract ejection, others have recently optimized inhibitors for picomolar affinities; however, cell penetration generally seems to remain an issue. To increase resilience against ejection, we engineered a “chem. spring” into prenyl-binding pocket inhibitors of PDE6D. Furthermore, cell penetration was improved by attaching a cell-penetration group, allowing us to arrive at micromolar in cellulo potencies in the first generation. Our model compounds, Deltaflexin-1 and -2, selectively disrupt K-Ras, but not H-Ras membrane organization. This selectivity profile is reflected in the antiproliferative activity on colorectal and breast cancer cells, as well as the ability to block stemness traits of lung and breast cancer cells. While our current model compounds still have a low in vitro potency, we expect that our modular and simple inhibitor redesign could significantly advance the development of pharmacol. more potent compounds against PDE6D and related targets, such as UNC119 in the future.

Tonzola, Christopher J. published the artcileNew silicon-containing polyquinolines: Synthesis, characterization, and electroluminescence, Synthetic Route of 14799-93-0, the publication is Macromolecular Chemistry and Physics (2005), 206(13), 1271-1279, database is CAplus.

This study reports the synthesis, characterization, and electroluminescent device application of three new silicon-containing polyquinolines: poly(2,2′-(bis(p-phenyl)-diphenylsilane)-6,6′-bis(4-Ph quinoline)), poly(2,2′-(bis(p-phenyl)octylmethylsilane)-6,6′-bis(4-Ph quinoline)), and poly(2,2′-(bis(p-phenyl)diphenylsilane)-6,6′-bis(4-hexylquinoline)). The polymers with alkyl side chains were soluble in organic solvents. The new polymers showed robust thermal properties with glass transitions of 161°-339°. Cyclic voltammetry of the polymers revealed quasireversible reductions with onsets of -1.55 to -1.71 V (vs SCE) and corresponding electron affinities of 2.69-2.85 eV. Organic light-emitting devices using new polyquinolines as emissive materials showed blue (CIE coordinates = 0.21, 0.20) or blue-green (0.23, 0.36) electroluminescence with a moderate brightness (≈140 cd·m^-2) and efficiency (0.04%). The results demonstrate that silicon-containing polyquinolines are promising n-type wide band-gap semiconductors for organic electronics.

Kharbanda, Chetna published the artcileNovel Piperine Derivatives with Antidiabetic Effect as PPAR-γ Agonists, HPLC of Formula: 3696-23-9, the publication is Chemical Biology & Drug Design (2016), 88(3), 354-362, database is CAplus and MEDLINE.

Piperine is an alkaloid responsible for the pungency of black pepper. In this study, piperine isolated from Piper nigrum L. was hydrolyzed under basic condition to obtain piperic acid and was used as precursor to carry out the synthesis of twenty piperine derivatives containing benzothiazole moiety. All the benzothiazole derivatives were evaluated for their antidiabetic potential by OGT test followed by assessment of active derivatives on STZ-induced diabetic model. It was observed that nine of twenty novel piperine analogs (5b, 6a-h), showed significantly higher antidiabetic activity in comparison with rosiglitazone (standard). Furthermore, these active derivatives were evaluated for their action as PPAR-γ agonists demonstrating their mechanism of action. The effects on body weight, lipid peroxidation, and hepatotoxicity after administration with active derivatives were also studied to further establish these derivatives as lead mols. for treatment of diabetes with lesser side-effects.

Elwaie, Tamer A. published the artcileHER2 Kinase-Targeted Breast Cancer Therapy: Design, Synthesis, and In Vitro and In Vivo Evaluation of Novel Lapatinib Congeners as Selective and Potent HER2 Inhibitors with Favorable Metabolic Stability, Recommanded Product: 3-Chloro-4-fluoronitrobenzene, the publication is Journal of Medicinal Chemistry (2020), 63(24), 15906-15945, database is CAplus and MEDLINE.

HER2 kinase as a well-established target for breast cancer (BC) therapy is associated with aggressive clin. outcomes; thus, herein we present structural optimization for HER2-selective targeting. HER2 profiling of the developed derivatives demonstrated potent and selective inhibitions (IC₅₀: 5.4-12 nM) compared to lapatinib (IC₅₀: 95.5 nM). Favorably, 17d exhibited min. off-target kinase activation. NCI-5-dose screening revealed broad-spectrum activities (GI₅₀: 1.43-2.09μM) and 17d had a remarkable selectivity toward BC. Our compounds revealed significant selective and potent antiproliferative activities (~20-fold) against HER2+ (AU565, BT474) compared to HER2(-) cells. At 0.1 IC₅₀, 15i, 17d, and 25b inhibited pERK1/2 and pAkt by immunoblotting. Furthermore, 17d demonstrated potent in vivo tumor regression against the BT474 xenograft model. Notably, a metastasis case was observed in the vehicle but not in the test mice groups. CD-1 mice metabolic stability assay revealed high stability and low intrinsic clearance of 17d (T_1/2 > 145 min and CL_int(mic) < 9.6 mL/min/kg).

A generalized equation for linear solvation energy relations or complexation energy relations is developed which involves 6 terms: π^* (a solvent dipolarity-polarizability term), α (solvent hydrogen-bond acceptor term), β (solvent hydrogen-bond donor term), δ (solvent polarizability correction term), δ_H (Hildebrand solubility parameter), and ξ. This equation is reduced to a more manageable form by a judicious choice of solvents and reactants or indicators. One-, two- or three-parameter LFER involving different combinations of the above parameters and various types of physicochem. properties are observed A comprehensive collection of π^*, α, and β for 217 solvents is presented.
