The acetogenin Squamocin (<strong>1</strong>) isolated from <em>A. pittieri </em>showed cytotoxic activity against human acute lymphocytic leukaemia with a good selectivity against healthy blood cells. Additionally, from <em>A. pittieri</em> nine molecules were isolated, including a new 2-azaanthraquinone alkaloid, 4-methoxybenzo[g]isoquinoline-5,10-dione (<strong>2</strong>). From <em>C</em>. <em>costaricense</em> three molecules were isolated including a new 1-azaanthraquinone alkaloid, 6-hydroxy-9-methoxy-cleistopholine (<strong>3</strong>).</p&gt;}, number={1}, journal={Journal of the Chilean Chemical Society}, author={Parra, Jonathan}, year={2021}, month={Feb.}, pages={5047-5050} }
