Here we have described a systematic structure activity relationship (SAR) of a set of compounds inspired from cladosporin, a tool compound that targets parasite (Plasmodium falciparum) lysyl tRNA synthetase (KRS). Four sets of analogues, synthesized based on point changes in the chemical scaffold of cladosporin and other logical modifications and hybridizations, were assessed using high throughput enzymatic and parasitic assays along with in vitro pharmacokinetics. Co-crystallization of the most potent compound in our series (CL-2) with PfKRS revealed its structural basis of enzymatic binding and potency. Further, we report that CL-2 has performed better than cladosporin in terms of metabolic stability. It thus represents a new lead for further optimization toward the development of antimalarial drugs. Collectively, along with a lead compound, the series offers insights on how even the slightest chemical modification might play an important role in enhancing or decreasing the potency of a chemical scaffold.

Novel 2-(aryloxymethyl)aziridines and 2-((3-aryl-1-phenylallyloxy)methyl)aziridine derivatives were prepared via ring-opening reaction of epoxides. The synthesized derivatives were characterized by using elemental analysis (EA), FT-IR, 13C NMR, and 1H NMR. The in vitro antitubercular activities of the synthesized compounds were evaluated against Mycobacterium tuberculosis H37Rv (MTB H37Rv) strain using MTT-MABA assay. All the aziridine derivatives exhibited improved persuasive antitubercular activity against MTB H37Rv in comparison with standard drugs. Among the tested compounds, 2-(naphthalene-1-yloxy) methyl aziridine (5b), 2-(naphthalene-2-yloxy)methylaziridine (5c), 2-(m-tolyloxymethyl)aziridine (5e), 2-(3-(4-methoxyphenyl)-1-phenylalloxy)methylaziridine (12b) and 2-(3-(2-chlorophenyl)-1-phenylallyloxy)methylaziridine (12c) revealed promising activity against MTB H37Rv. Specifically, compound 5b and 12 b showed three-times more active (MIC = 0.5 μg/mL) than the standard drugs ethambutol (MIC = 1.56 μg/mL) and ciprofloxacin (MIC = 1.56 μg/mL).
