Synthesis of Triazole-Substituted Quinazoline Hybrids for Anticancer Activity and a Lead Compound as the EGFR Blocker and ROS Inducer Agent.

A series of triazole-substituted quinazoline hybrid compounds were designed and synthesized for anticancer activity targeting epidermal growth factor receptor (EGFR) tyrosine kinase. Most of the compounds showed moderate to good antiproliferative activity against four cancer cell lines (HepG2, HCT116, MCF-7, and PC-3). Compound showed good antiproliferative activity (IC = 20.

Detection of Lysosome by a Fluorescent Heterocycle: Development of Fused Pyrido-Imidazo-Indole Framework via Cu-Catalyzed Tandem N-Arylation.

Fluorescent active small molecules for organelle-specific bioimaging are in great demand. We synthesized 20 different pyrido-imidazo-indole fused heterocycles (6-5-5-6 ring) via copper catalyzed tandem N-arylation reaction in moderate to good yields. Due to decent fluorescent property, lysosome-directing moieties were attached on two of these heterocycles.
