Three diversity points of 4(3H)-quinazolinone are introduced at the 3-, 6-, and 7-positions with an efficient parallel solution-phase synthetic method. A one-pot synthesis was developed that gave the key intermediate in high yield. Five hit compounds exhibit preferable activities against a panel of human tumor cell lines, which pointed out preliminary structure-activity relationships.
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
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.
