1. INTRODUCTION The length of straightened-out DNA in a single cell is nearly 2 m. In
mammalian cells, the nucleus has a diameter of approximately 6 μm and occupies about …

Pyrazine is a six-membered heterocyclic ring containing nitrogen, and many of its
derivatives are biologically active compounds. References have been downloaded through …

An efficient and practical route to novel fluorescent benzo [a] pyrano [2, 3-c] phenazine
framework has been developed by one-pot, four-component reaction of 2 …

Abstract Two series of amino‐1, 4‐benzoquinones (AQ1–18) based on the structural
analogs of plastoquinones were synthesized and the structure–activity relationship against …

A one-pot route for the synthesis of spiro-isobenzofuran compounds was developed via the
condensation reaction of ninhydrin with 4-amino-1, 2-naphthoquinones or 2-amino-1, 4 …

Thirty 2-phenylquinazolin-4 (3H)-one derivatives were prepared and their cytotoxic activities
were tested in five human tumor cell lines. Some compounds (5e, 5k, 5t, 6c and 6f) showed …

Caffeine was applied as a green and natural catalyst for the one-pot, four-component
sequential condensation between 2-hydroxy-1, 4-naphthoquinone, aromatic 1, 2-diamines …

An efficient, convenient and environmentally benign procedure for the synthesis of novel 3-
oxo-3H-benzo [a] pyrano [2, 3-c] phenazine-1-carboxylate and 3-(5-hydroxybenzo [a] …

A new one pot three-component reaction for the synthesis of benzo [a] pyrano-[2, 3-c]
phenazine derivatives has been developed. The synthesis was achieved by reacting benzo …

A highly efficient one-pot, two-step microwave-assisted procedure was applied for the rapid
and green synthesis of benzo [a] phenazine annulated heterocyclic ring systems from the …
