Used in Pharmaceutical Industry:
(4-Chloro-6-methyl-pyrimidin-2-yl)-ethyl-amine is used as a synthetic intermediate for the development of pyrimidine-based inhibitors of Dynamin I GTPase. These inhibitors play a crucial role in regulating cellular processes such as endocytosis, vesicle formation, and intracellular signaling pathways. By targeting Dynamin I GTPase, these pyrimidine-based inhibitors have the potential to be used in the treatment of various diseases, including neurological disorders and cancer.

The invention provides the compounds for use in the prevention and treatment of infectious diseases, in particular viral diseases. In some aspects the invention is based on the antiviral activity of the provided compounds against the Chikungunya virus, and hence, their application in the treatment or prevention of any physiological manifestation of such viral infection.

Discovery of a Novel Mycobacterial F-ATP Synthase Inhibitor and its Potency in Combination with Diarylquinolines

The F1FO-ATP synthase is required for growth and viability of Mycobacterium tuberculosis and is a validated clinical target. A mycobacterium-specific loop of the enzyme's rotary γ subunit plays a role in the coupling of ATP synthesis within the enzyme complex. We report the discovery of a novel antimycobacterial, termed GaMF1, that targets this γ subunit loop. Biochemical and NMR studies show that GaMF1 inhibits ATP synthase activity by binding to the loop. GaMF1 is bactericidal and is active against multidrug- as well as bedaquiline-resistant strains. Chemistry efforts on the scaffold revealed a dynamic structure activity relationship and delivered analogues with nanomolar potencies. Combining GaMF1 with bedaquiline or novel diarylquinoline analogues showed potentiation without inducing genotoxicity or phenotypic changes in a human embryonic stem cell reporter assay. These results suggest that GaMF1 presents an attractive lead for the discovery of a novel class of anti-tuberculosis F-ATP synthase inhibitors.

Identification of 2-(4-(Phenylsulfonyl)piperazine-1-yl)pyrimidine Analogues as Novel Inhibitors of Chikungunya Virus

The chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus, and it is the causative agent of chikungunya fever (CHIKF). Although it has re-emerged as an epidemic threat, so far there are neither vaccines nor pharmacotherapy available to prevent or treat an infection. Herein, we describe the synthesis and structure-activity relationship studies of a class of novel small molecule inhibitors against CHIKV and the discovery of a new potent inhibitor (compound 6a). The starting point of the optimization process was N-ethyl-6-methyl-2-(4-(4-fluorophenylsulfonyl)piperazine-1-yl)pyrimidine-4-amine (1) with an EC50 of 8.68 μM, a CC50 of 122 μM, and therefore a resulting selectivity index (SI) of 14.2. The optimized compound 6a, however, displays a much lower micromolar antiviral activity (EC50 value of 3.95 μM), considerably better cytotoxic liability (CC50 value of 260 μM) and consequently an improved SI of greater than 61. Therefore, we report the identification of a promising novel compound class that has the potential for further development of antiviral drugs against the CHIKV.

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.
