Discovery of 1,4-Benzodiazepine-2,5-dione (BZD) Derivatives as Dual Nucleotide Binding Oligomerization Domain Containing 1/2 (NOD1/NOD2) Antagonists Sensitizing Paclitaxel (PTX) To Suppress Lewis Lung Carcinoma (LLC) Growth in Vivo
摘要:
Nucleotide-binding oligomerization domain-like receptors (NLRs) are intracellular sensors of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs). Previously, we reported nucleotide-binding oligomerization domain-containing protein 1 (NOD1) antagonists (II, 12) and a NOD2 antagonist (9) that sensitized docetaxel (DTX) or paclitaxel (PTX) treatment for breast or lung cancer. In this article, we describe for the first time a 1,4-benzodiazepine-2,5-dione (BZD) derivative (26bh) that acts as a dual NOD1/NOD2 antagonist and inhibits both nuclear factor kappa B (NF-kappa B) and mitogen-activated protein kinase (MAPK) inflammatory signaling, thereby sensitizing PTX to suppress Lewis lung carcinoma (LLC) growth. After investigation of the compound's cytotoxicity, a systematic structure-activity relationship (SAR) was completed and revealed several key factors that were necessary to maintain antagonistic ability. This study establishes the possibility for using adjuvant treatment to combat cancer by antagonizing both NOD1 and NOD2 signaling.

A practical and efficient method for the direct, regioselective conversion of vinylogousesters to haloresorcinols is reported. Control of the reaction conditions enables synthesis of either the 4- or 6-haloresorcinol isomers from a common precursor with excellent regiocontrol and high yield. The generality and functional group tolerance of this novel protocol is demonstrated. The utility of this methodology

Certain phenols and anilines can be used as electron transfer agents to increase the rate of oxidation of leuco dyes by peroxidase. These phenols and anilines can react the hydrogen peroxide in the presence of peroxidase to provide intermediates which have higher oxidation potentials than the slowly oxidized substrates, for example, the leuco dyes. These phenols and anilines can be used to advantage in both solution and dry assays of various analytes. They are particularly useful for the determination of an immunologically reactive ligand in an immunoassay.

(EN) An aqueous immunological composition comprises a detectably labeled antibody to a Streptococcal antigen, and a water-soluble or water-dispersible nonionic surfactant. This composition provides improved background and spot quality in assays for Streptococcal antigens. Such advantages are particularly evident with assays carried out using filter membranes to capture the immunological product. The composition can be included in a diagnostic test kit for use in the assay.(FR) Une composition immunologique aqueuse comprend un anticorps marqué de manière détectable contre un antigène streptococcique, et un agent tensio-actif non ionique soluble dans l'eau et dispersible dans l'eau. Cete composition améliore la qualité de fond et ponctuelle dans des analyses de détection d'antigènes streptococciques. De tels avantages sont particulièrement appréciés lors d'analyses effectuées avec des membranes de filtre pour capturer le produit immunologique. La composition peut être incorporée dans un kit de test diagnostique utilisé dans l'analyse.
