Crystal and molecular structures of benzyl-(2-chloro-6-methylpyrimidin-4- yl)amine and benzyl-(4-chloro-6-methylpyrimidin-2-yl)amine: Confirmation of computationally predicted restricted rotation

Crystal structures for the isomeric compounds benzyl-(2-chloro-6- methylpyrimidin-4-yl)amine (1), as its hemi-hydrate, and benzyl-(4-chloro-6- methylpyrimidin-2-yl)amine (2) have been determined. Conformational differences lead to multiple molecules, i.e.

2,4-Diamino-6-methylpyrimidines for the potential treatment of Chagas’ disease

Chagas’ disease, caused by the protozoan parasite Trypanosoma cruzi, affects 8–10 million people across the Latin American population and is responsible for around 12,500 deaths per annum. The current frontline treatments, benznidazole and nifurtimox, are associated with side effects and lack efficacy in the chronic stage of the disease, leading to an urgent need for new treatments. A high throughput screening campaign against the physiologically relevant intracellular form of the parasite identified a series of 2,4-diamino-6-methylpyrimidines. Demonstrating the series did not work through the anti-target TcCYP51, and was generally cytocidal, confirmed its suitability for further development. This study reports the optimisation of selectivity and metabolic stability of the series and identification of a suitable lead for further optimisation.

Pyrimidine-Based Inhibitors of Dynamin I GTPase Activity: Competitive Inhibition at the Pleckstrin Homology Domain

The large GTPase dynamin mediates membrane fission during clathrin-mediated endocytosis (CME). The aminopyrimidine compounds were reported to disrupt dynamin localization to the plasma membrane via the PH domain and implicate this mechanism in the inhibition of CME. We have used a computational approach of binding site identification, docking, and interaction energy calculations to design and synthesize a new library of aminopyrimidine analogues targeting site-2 of the pleckstrin homology (PH) domain. The optimized analogues showed low micromolar inhibition against both dynamin I (IC50 = 10.6 ± 1.3 to 1.6 ± 0.3 μM) and CME (IC50(CME) = 65.9 ± 7.7 to 3.7 ± 1.1 mM), which makes this series among the more potent inhibitors of dynamin and CME yet reported. In CME and growth inhibition cell-based assays, the data obtained was consistent with dynamin inhibition. CEREP ExpresS profiling identified off-target effects at the cholecystokinin, dopamine D2, histamine H1 and H2, melanocortin, melatonin, muscarinic M1 and M3, neurokinin, opioid KOP and serotonin receptors.

MONOCYCLIC PYRIMIDINE/PYRIDINE COMPOUNDS AS INHIBITORS OF P97 COMPLEX

Monocyclic pyrimidine and pyridine compounds having a benzyl amine substituent at the 4 position and a 5:6 bicyclic heteroaryl substituent at the 2 position of the pyrimidine or pyridine ring as well as optional aliphatic, functional and/or aromatic components substituted at other positions of the ring are disclosed. These compounds are inhibitors of the AAA proteasome complex containing p97 and are effective medicinal agents for treatment of diseases associated with p97 bioactivity such as cancer.

A natural product inspired hybrid approach towards the synthesis of novel pentamidine based scaffolds as potential anti-parasitic agents

A natural product inspired molecular hybridization approach led us to a series of novel pentamidine based pyrimidine and chalcone scaffolds. All the hybrids were evaluated for their anti-leishmanial potential. Most of the screened compounds have showed significant in vitro anti-leishmanial activity with less cytotoxicity in comparison to the standard drugs (pentamidine, sodium stibogluconate, and miltefosine). Additionally, anti-malarial screening of these compounds was also done and four compounds have shown superior activity against chloroquine resistance strain (K1) of Plasmodium falciparum.

Synthesis and antiplasmodial activity of novel 2,4-diaminopyrimidines

Two sets of diaminopyrimidines, totalling 45 compounds, were synthesized and assayed against Plasmodium falciparum. The SAR was relatively shallow, with only the presence of a 2-(pyrrolidin-1-yl)ethyl group at R2 significantly affecting activity. A subsequent series addressed high Log D values by introducing more polar side groups, with the most active compounds possessing diazepine and N-benzyl-4-aminopiperidyl groups at R1/R2. A final series attempted to address high in vitro microsomal clearance by replacing the C6-Me group with CF3, however antiplasmodial activity decreased without any improvement in clearance. The C6-CF3 group decreased hERG inhibition, probably as a result of decreased amine basicity at C2/C4.
