Huang, Xiaohua published the artcileDiscovery and Hit-to-Lead Optimization of Non-ATP Competitive MK2 (MAPKAPK2) Inhibitors, Formula: C7H8BClO2, the publication is ACS Medicinal Chemistry Letters (2011), 2(8), 632-637, database is CAplus and MEDLINE.

A novel series of non-ATP-competitive MK2 inhibitors based on a furan-2-carboxyamide scaffold was discovered through high-throughput screening using the affinity selection-mass spectrometry-based Automated Ligand Identification System platform. Medicinal chem. efforts optimized the initial screening hit to lead-like compounds with significant improvements in biochem. and cellular potencies, while maintaining excellent kinase selectivity and in vitro pharmacokinetic properties. Biophys. and biochem. studies confirmed the unique non-ATP-competitive binding mode of this series and suggested that highly selective inhibitors of MK2 should be feasible by targeting the outside ATP pocket.

Hayakawa, Ichiro published the artcileStructure-activity relationship study of gatastatin based on the topliss tree approach, Application In Synthesis of 620-20-2, the publication is Heterocycles (2019), 99(1), 238-247, database is CAplus.

Various analogs of gatastatin I [Ar = 3-ClC₆H₄, 4-MeC₆H₄, 4-^tButC₆H₄, etc.], a γ-tubulin-specific inhibitor, were designed and synthesized by systematically optimizing the aromatic ring at the O⁷-benzyl group in accordance with an operational Topliss tree, and their biol. activities were evaluated. Some derivatives showed stronger cytotoxicity against HeLa cells than gatastatin. Especially, the cytotoxicity of the I [Ar = 3-ClC₆H₄] derivative was about 18-fold stronger than that of gatastatin. However, these derivatives did not exhibit binding ability to the yeast γ-tubulin small complex or inhibitory activity against α,β-tubulin polymerization These results suggested that γ-tubulin strongly recognized the unsubstituted Ph ring of the O⁷-benzyl group in gatastatin.

Title compound I, labeled with ¹⁴C in the 2-position, was prepared in 30.7% yield by cyclocondensation of NH₂CH₂CH₂SH with ¹⁴C-labeled CH₂O in H₂O at pH = 8, followed by nitrosylation of the thiazolidine with NaNO₂ at pH = 4.5 adjusted with H₂SO₄. Adjustment of the pH in the latter step with HCl forms many disulfide byproducts.

Fronk, Stephanie L. published the artcileChiroptical Properties of a Benzotriazole-Thiophene Copolymer Bearing Chiral Ethylhexyl Side Chains, Synthetic Route of 21286-54-4, the publication is Macromolecules (Washington, DC, United States) (2016), 49(24), 9301-9308, database is CAplus.

Conjugated polymers containing alternating thiophene units and benzotriazole structural units bearing either chiral (S)-2-ethylhexyl (PBTz-Th*) or racemic 2-ethylhexyl side chains (PBTz-Th) were synthesized. Characterization by optical absorption spectroscopy of both PBTz-Th* and its racemic counterpart reveal aggregated chains, even at dilute concentrations in good solvents. The presence of a chiral substituent permits characterization via CD (CD) spectroscopy. CD spectra provide evidence of chiral aggregates of PBTz-Th* chains even at 0.01 mg/mL in dichlorobenzene. When PBTz-Th* solutions are diluted with PBTz-Th, the resulting CD spectrum suggests that PBTz-Th* chains are chiral in the aggregate. Chiral ordering is also found to translate from aggregates in solution to the solid state.
