AbstractMany marine derived fatty acids, mainly from sponges, possess vinylic halogenated moieties (bromine or iodine) but their assessment as antileishmanial candidates remains elusive. In this work, we undertook the first total synthesis of a novel series of 2-allyl-3-halo-2-nonadecenoic acids, which preferentially inhibit theLeishmaniaDNA topoisomerase IB enzyme (LTopIB) over the human topoisomerase IB enzyme (hTopIB). The synthesis of 2-allyl-3-bromo-2E-nonadecenoic acid (1a) and 2-allyl-3-chloro-2E-nonadecenoic acid (2a) was achieved through a palladium catalyzed haloallylation of 2-nonadecynoic acid (2-NDA) using either allyl bromide or allyl chloride in the presence of PdCl2(PhCN)2in 57–83 % overall yields. Among the new halogenated synthetic compounds,1awas the most inhibitory ofLTopIB with an EC50 = 7 μM, while the shorter chain analogs 2-allyl-3-bromo-2E-dodecenoic acid (1b) and 2-allyl-3-chloro-2E-dodecenoic acid (2b), synthesized from 2-dodecynoic acid, were not inhibitory ofLTopIB (EC50 > 100 μM) resulting in the overall order of inhibition1a > 2-NDA > 2a > > 1b ≅ 2b. The acids1aand2ainhibitLTopIB by a Gimatecan-independent mechanism. The enhancedLTopIB inhibition of1awas computationally rationalized in terms of a halogen bond between the bromine in1aand a DNA phosphate (binding energy = − 4.85 kcal/mol). Acid1aalso displayed preferential cytotoxicity towardsLeishmania infantumamastigotes (EC50 = 2.5 μM) overL. infantumpromastigotes (EC50 > 25 μM).
