To tackle leishmaniasis, search for efficient therapeutic drug targets should be pursued. Dihydrofolate reductase (DHFR) is considered as a key target for the treatment of leishmaniasis. In current study, we are interested in the design and synthesis of selective antifolates targeting DHFR from L. major. We focused on the development of new antifolates based on 3,4-dihydropyrimidine-2-one and 5-(3,5-dimethoxybenzyl)pyrimidine-2,4-diamine motif. Structure activity relationship (SAR) studies were performed on 4-phenyl ring of dihydropyrimidine (26–30) template. While for 5-(3,5-dimethoxybenzyl)pyrimidine-2,4-diamine, the impact of different amino acids (valine, tryptophan, phenylalanine, and glutamic acid) and two carbon linkers were explored (52–59). The synthesized compounds were assayed against LmDHFR. Compound 59 with the IC50 value of 0.10 μM appeared as potent inhibitors of L. major. Selectivity for parasite DHFR over human DHFR was also determined. Derivatives 55–59 demonstrated excellent selectivity for LmDHFR. Highest selectivity for LmDHFR was shown by compounds 56 (SI = 84.5) and 58 (SI = 87.5). Compounds Antileishmanial activity against L. major and L. donovani promastigotes was also performed. To explore the interaction pattern of the synthesized compounds with biological macromolecules, the docking studies were carried out against homology modelled LmDHFR and hDHFR targets.

Seven novel lipoamino acid conjugates were synthesized from methyl oleate and amino acids. Methyl oleate was grafted to different amino acids using thioglycolic acid as a spacer group. Seven derivatives (3a-g) were prepared and characterized by spectral data (NMR, IR and MS spectral studies). All the derivatives were studied for their antimicrobial, anti-biofilm and anticancer activities. Among all the derivatives, it was found that compound 3b was the most potent antibacterial compound which showed good activity against four Gram positive bacterial strains and also exhibited excellent antifungal activity against a fungal strain. In the anti-biofilm assay, compound 3b showed promising activity with IC50 value of 2.8 μM against Bacillus subtilis MTCC 121. All the compounds showed anticancer activities with 3c showing promising anticancer activity (IC50 = 15.3-22.4 μM) against the four cell lines tested.
