, p. 455 - 457 (1990)
Dodec-10E-en-1-yl acetate - the sex pheromone of the apple leaf miner moth - has been obtained by a four-stage synthesis from monomethyl azelate and crotyl acetate.Its IR, PMR, and mass spectra are given.
Lipoic acid metabolism in Trypanosoma cruzi as putative target for chemotherapy

, p. 17 - 23 (2018)
Lipoic acid (LA) is a cofactor of relevant enzymatic complexes including the glycine cleave system and 2-ketoacid dehydrogenases. Intervention on LA de novo synthesis or salvage could have pleiotropic deleterious effect in cells, making both pathways attractive for chemotherapy. We show that Trypanosoma cruzi was susceptible to treatment with LA analogues. 8-Bromo-octanic acid (BrO) inhibited the growth of epimastigote forms of both Dm28c and CL Brener strains, although only at high (chemotherapeutically irrelevant) concentrations. The methyl ester derivative MBrO, was much more effective, with EC50 values one order of magnitude lower (62–66 μM). LA did not bypass the toxic effect of its analogues. Small monocarboxylic acids appear to be poorly internalized by T. cruzi: [14C]-octanoic acid was taken up 12 fold less efficiently than [14C]-palmitic acid. Western blot analysis of lipoylated proteins allowed the detection of the E2 subunits of pyruvate dehydrogenase (PDH), branched chain 2-ketoacid dehydrogenase and 2-ketoglutarate dehydrogenase complexes. Growth of parasites in medium with 10 fold lower glucose content, notably increased PDH activity and the level of its lipoylated E2 subunit. Treatment with BrO (1 mM) and MBrO (0.1 mM) completely inhibited E2 lipoylation and all three dehydrogenases activities. These observations indicate the lack of specific transporters for octanoic acid and most probably also for BrO and LA, which is in agreement with the lack of a LA salvage pathway, as previously suggested for T. brucei. They also indicate that the LA synthesis/protein lipoylation pathway could be a valid target for drug intervention. Moreover, the free LA available in the host would not interfere with such chemotherapeutic treatments.
4-Acyl Pyrrole Capped HDAC Inhibitors: A New Scaffold for Hybrid Inhibitors of BET Proteins and Histone Deacetylases as Antileukemia Drug Leads

Multitarget drugs are an emerging alternative to combination therapies. In three iterative cycles of design, synthesis, and biological evaluation, we developed a novel type of potent hybrid inhibitors of bromodomain, and extra-terminal (BET) proteins and histone deacetylases (HDACs) based on the BET inhibitor XD14 and well-established HDAC inhibitors. The most promising new hybrids, 49 and 61, displayed submicromolar inhibitory activity against HDAC1-3 and 6, and BRD4(1), and possess potent antileukemia activity. 49 induced apoptosis more effectively than the combination of ricolinostat and birabresib (1:1). The most balanced dual inhibitor, 61, induced significantly more apoptosis than the related control compounds 62 (no BRD4(1) affinity) and 63 (no HDAC inhibition) as well as the 1:1 combination of both. Additionally, 61 was well tolerated in an in vivo zebrafish toxicity model. Overall, our data suggest an advantage of dual HDAC/BET inhibitors over the combination of two single targeted compounds.
Asymmetric syntheses of potential anti-malarial drugs designed from Fieser's 2-hydroxy-3-(2-methyloctyl)naphthalene-1,4-dione

We describe asymmetric syntheses of the potential anti-malarial drugs (S)-2-(8-fluoro-2-methyloctyl)-3-hydroxynaphthalene-1,4-dione, (S)-2-hydroxy-3-(8-trifluoromethyl-2-methyloctyl)-3-hydroxynaphthalene-1,4-dione, and (S)-2-hydroxy-3-(2-methyloctyl)naphthalene-1,4-dione, which are patterned after Fieser's “10576,” known to be active against the mosquito borne parasite Plasmodium falciparum.
