With roughly 2 billion people infected, the neurotropic protozoan Toxoplasma gondii remains one of the most pervasive and infectious parasites. Toxoplasma infection is the second leading cause of death due to foodborne illness in the United States, causes severe disease in immunocompromised patients, and is correlated with several cognitive and neurological disorders. Currently, no therapies exist that are capable of eliminating the persistent infection in the central nervous system (CNS). In this study we report the identification of triazine nitrile inhibitors of Toxoplasma cathepsin L (TgCPL) from a high throughput screen and their subsequent optimization. Through rational design, we improved inhibitor potency to as low as 5 nM, identified pharmacophore features that can be exploited for isoform selectivity (up to 7-fold for TgCPL versus human isoform), and improved metabolic stability (t1/2 > 60 min in mouse liver microsomes) guided by a metabolite ID study. We demonstrated that this class of compounds is capable of crossing the blood-brain barrier in mice (1:1 brain/plasma at 2 h). Importantly, we also show for the first time that treatment of T. gondii bradyzoite cysts in vitro with triazine nitrile inhibitors reduces parasite viability with efficacy equivalent to a TgCPL genetic knockout.

Conditions for selective substitution for one chlorine atom in 2-(R,R-amino)-4,6-dichloro-1,3,5-triazines with a hydroxide ion were elaborated. Spectral and calculation methods showed that the products formed are in the lactam form, i.e., have the structure of 4-chloro-6-(R,R- amino)-1,3,5-triazin-2(1H)-ones.

Selectively functionalized glycerol/diacid dendrimers via click chemistry of azido fatty acids
Zerkowski, Jonathan A.,Nunez, Alberto,Solaiman, Daniel K. Y.
experimental part, p. 403 - 413 (2011/10/18)
Dendrimers consisting of glycerol and dicarboxylic acid units were synthesized using a convergent or "outside-in" strategy. The multimeric arms, or dendrons, are joined to a central core in the final step using the azide/alkyne click reaction. The combination of these approaches allows the preparation of dendrimers with variable and controlled degrees of substitution at their periphery. For example, a single protected amino acid has been situated at the periphery, with all other substituents being hydrophobic. In another example, all the peripheral substituents are protected amino acids. The identity of the dendrimers is unambiguous due to the purification and characterization of all the synthetic intermediates. Functional groups have also been selectively incorporated along the arms (dicarboxylic acids) and at the cores.
