Screening of a designed collection of mono-substituted amino-IH-phenalen-1-ones against promastigote forms of L. donovani and L. amazonensis, identified seven compounds with anti-leishmanial activities comparable or better than the commonly prescribed anti-leishmanial drug, miltefosine. Structure activity analysis revealed that appendages containing a basic tertiary nitrogen were favored, and that the position of the appendage also affected their potency. Like miltefosine, several of these active compounds significantly reduced the mitochondrial membrane potential in promastigotes. Further studies in amastigotes of L. amazonensis revealed that compounds 14, 15 and 33 were more active and more selective than miltefosine, with sub-micromolar potencies and selectivity indices > 100.

produced both singlet oxygen and red fluorescence efficiently. OE19 induced photocytotoxicity with nanomolar potency in 2D cultured PANC-1 cancercells as well as light-induced destruction of PANC-1 spheroids with minimal dark toxicity. Overall, OE19 opens up the possibility of employing phenalenone-based photosensitizers as theranosticagents for photodynamic cancer therapy.
