Synthesis of perspicamide A and related diverse analogues: their bioevaluation as potent antileishmanial agents.

The first protocol for the synthesis of perspicamide A and related diverse analogues has been developed from economical and readily available starting materials. Furthermore, a few synthesized analogues, 24a, 24b, 24c, 24d, and 24l, exhibited potent activity against Leishmania donovani with IC(50) values ranging from 3.75 to 10.37 μM and a selectivity index (SI) ranging from 9.58 to 53.12, which is improved compared to the standard drug Miltefosine (IC(50) 12.4 μM and SI 4.1).
