Discovery of a Locally and Orally Active CXCL12 Neutraligand (LIT-927) with Anti-inflammatory Effect in a Murine Model of Allergic Airway Hypereosinophilia
摘要:
We previously reported Chalcone-4 (1) that binds the chemokine CXCL12, not its cognate receptors CXCR4 or CXCR7, and neutralizes its biological activity. However, this neutraligand suffers from limitations such as poor chemical stability, solubility, and oral activity. Herein, we report on the discovery of pyrimidinone 57 (LIT-927), a novel neutraligand of CXCL12 which displays a higher solubility than 1 and is no longer a Michael acceptor. While both 1 and 57 reduce eosinophil recruitment in a murine model of allergic airway hypereosinophilia, 57 is the only one to display inhibitory activity following oral administration. Thereby, we here describe 57 as the first orally active CXCL12 neutraligand with anti-inflammatory properties. Combined with a high binding selectivity for CXCL12 over other chemokines, 57 represents a powerful pharmacological tool to investigate CXCL12 physiology in vivo and to explore the activity of chemokine neutralization in inflammatory and related diseases.

A library of sixty-five chalcones was prepared for screening against the protein phosphatase, cdc25B. From this library, thirteen compounds were found having good inhibitory activity. Two compounds have excellent activity and can be used for the design of more potent antiproliferative agents.
group which is liable for the antimicrobial activity of the chalcone is additionally of vast use in further chemical modification into a variety of heterocyclic compounds. A new series of chalcone derivatives was synthesized and characterized by spectral analysis (IR, 1H-NMR, 13C-NMR, MS and elemental analysis) and evaluated for its in vitro antimicrobial activity against bacterial (Gram negative and Gram
An array of chalcones from vanillin/isovanillin and differently substituted acetophenones were synthesized and assessed for their anticancer activity against A549, MCF7 and MIA PaCa-2 cell lines using MTT assay. Some of the chalcones exhibited good anticancer activity with IC50 values below 10 mu M. Compound 5f with IC50 values 5.4 +/- A 0.7, 10.45 +/- A 2.15 and 13.0 +/- A 1.68 A mu M on MIA PaCa-2, A549 and MCF7, respectively, was more potent than curcumin and hence was analyzed for changes in cell morphology, inhibition of cell migration, mechanism of cell death and arrest of cell cycle progression on MIA PaCa-2 cells.
