The continuously increasing use of trimethoprim as a common antibiotic for medical use and for prophylactic application in terrestrial and aquatic animal farming has increased its prevalence in the environment. This has been accompanied by increased drug

A series of bisbenzaldehydes and structurally related analogs, conveniently synthesized via microwave-assisted reactions, were evaluated in vitro against drug susceptible and multi-drug resistant Mycobacterium tuberculosis, against virulent Mycobacterium bovis, against Mycobacterium ulcerans and against two Mycobacterium avium subspecies. Among the 33 substances that were tested, compound 12, i.e. 4,4′-[1,12-dodecanediyl(oxy)]bisbenzaldehyde, emerged as the most promising hit. Its activity was further confirmed in an intracellular growth inhibition assay of M. tb in murine J774 A.1 macrophages. None of the compounds showed significant cytotoxicity on human C3A hepatocytes in a neutral red dye uptake assay and no genotoxicity or mutagenicity was observed as demonstrated by a VITOTOX test and confirmed with a comet assay.

Symmetrical bishydroxamic acids along with their sodium salts containing an alkyl spacer between two aromatic rings were synthesized, and their antiparasitic activities were evaluated. Bishydroxamic acids were conveniently prepared from the alkylation of methyl 4-hydroxybenzoate with various dihalo-alkane, -alkene, and -ether followed by reaction with hydroxylamine. Surprisingly, the bishydroxamic acids and their sodium salts possess strong inhibitory activities against Plasmodium falciparum parasites with IC 50 values in the range of 0.26-3.2 μM. Bishydroxamic acid 3 and its sodium salt 12 also inhibit the growth of Leishmania donovani, albeit at higher concentrations. The corresponding biscarboxylic acids and bismethyl esters are inactive. Presumably, the ability of bishydroxamic acids to complex with metallic iron in hemoglobin may be responsible for antimalarial activity of these compounds.
