O-11 is an analog of the fully saturated, 14-carbon fatty acid myristic acid, in which the methylene group at position 11 is replaced with oxygen. It is highly effective and selective at killingTrypanosoma brucei, the protozoan parasite responsible for African sleeping sickness, exhibiting an LD50of less than 1 μM in a cell culture assay.1,2The toxic effects of O-11 appear to be caused by its ability to inhibit the incorporation of a single myristate into the GPI anchor of the variant surface glycoprotein (VSG), a protein critical for evading the host immune response.1O-11 exhibits essentially no anti-fungal activity when assayed usingC. neoformans, but does have a minor inhibitory effect on HIV-1 replication in T-lymphocytes.3 1.Doering, T.L., Raper, J., Buxbaum, L.U., et al.An analog of myristic acid with selective toxicity for African trypanosomesScience2521851-1854(1991) 2.Doering, T.L., Lu, T., Werbovetz, K.A., et al.Toxicity of myristic acid analogs toward African trypanosomesProceedings of the National Academy of Sciences of the United States of America919735-9739(1994) 3.Langner, C.A., Lodge, J.K., Travis, S.J., et al.4-Oxatetradecanoic acid is fungicidal for Cryptococcus neoformans and inhibits replication of human immunodeficiency virus IThe Journal of Biological Chemisty267(24)17159-17169(1992)

The leguminous shrub,Leucaena leucocephala(Leucaena) is wide‐spread in tropical and subtropical agricultural systems and provides a ready source of protein for livestock. However, the presence of mimosine, a non‐protein, amino acid comprising about 12% of the dry matter in growing tips ofLeucaena, is toxic to animals. Mimosine is degraded rapidly in the rumen to produce 3,4‐dihydroxypyridine (3,4‐DHP) and 2,3‐dihydroxypyridine (2,3‐DHP), both of which remain toxic to animals[1]. 3,4-DHP, as a derivative of the plant amino acid mimosine, is goitrogenic in cattle, sheep, and mice. In contrast to established antithyroid compounds, such as methimazole (MMI) and propylthiouracil (PTU), 3,4-DHP has no SH-group. 3,4-DHP with various concentrations inhibited incorporation of125I into protein in human thyroid slices. It also suppressed the activation of lymphocytes by PHA (phytohaemagglutinin) and PWM (pokeweed mitogen). Suppression with 3,4-DHP was seen at 100 and 1000 μmol L (P< 0.001 vs both PHA and PWM). Those, together with a very low murine bone marrow toxicity, probably related to the absence of an SH-group, make 3,4-DHP a potential antithyroid drug[2].

Dibrospidium Free Base is a dispirotripiperazine derivative and alkylating agent with potential antineoplastic and anti-inflammatory activities. The duration of DNA synthesis inhibition in tumor cells was found to correlate with spirobromine antitumor activity. Spirobromin is superior to prospidin by the power of the anti-inflammatory effect. Spyrobromin can diminish the latent period of the development of tumours in the experimental rats at intraperitoneal administration. At intragastric administration of the drug no decrease was noted in the latent period and no increase of tumours was observed in the experimental groups of the animals as compared with control. Dibrospidium has been examined for the treatment of bone cancer. The oral route of administration is the most safe with respect to the oncogenic risk. It was noted that spirobromin exerted the most pronounced toxic action on erythrocytes. Dibrospidium is used for the treatment of acute leukemias (mainly in combinatio......
