Covalent inhibition of the histamine H3 receptor
Covalent binding of G protein-coupled receptors by small molecules is a useful approach for better understanding of the structure and function of these proteins. We designed, synthesized and characterized a series of 6 potential covalent ligands for the histamine H3 receptor (H3R). Starting from a 2-amino-pyrimidine scaffold, optimization of anchor moiety and warhead followed by fine-tuning of the required reactivity via scaffold hopping resulted in the isothiocyanate H3R ligand 44. It shows high reactivity toward glutathione combined with appropriate stability in water and reacts selectively with the cysteine sidechain in a model nonapeptide equipped with nucleophilic residues. The covalent interaction of 44 with H3R was validated with washout experiments and leads to inverse agonism on H3R. Irreversible binder 44 (VUF15662) may serve as a useful tool compound to stabilize the inactive H3R conformation and to study the consequences of prolonged inhibition of the H3R.

4-(3-Aminoazetidin-1-yl)pyrimidin-2-amines as High-Affinity Non-imidazole Histamine H3 Receptor Agonists with in Vivo Central Nervous System Activity
Despite the high diversity of histamine H3 receptor (H3R) antagonist/inverse agonist structures, partial or full H3R agonists have typically been imidazole derivatives. An in-house screening campaign intriguingly afforded

Discovery and SAR of 6-alkyl-2,4-diaminopyrimidines as histamine H 4 receptor antagonists
This report discloses the discovery and SAR of a series of 6-alkyl-2-aminopyrimidine derived histamine H4 antagonists that led to the development of JNJ 39758979, which has been studied in phase II clinical trials in asthma and atopic dermatitis. Building on our SAR studies of saturated derivatives from the indole carboxamide series, typified by JNJ 7777120, and incorporating knowledge from the tricyclic pyrimidines led us to the 6-alkyl-2,4-diaminopyrimidine series. A focused medicinal chemistry effort delivered several 6-alkyl-2,4-diaminopyrimidines that behaved as antagonists at both the human and rodent H4 receptor. Further optimization led to a panel of antagonists that were profiled in animal models of inflammatory disease. On the basis of the preclinical profile and efficacy in several animal models, JNJ 39758979 was selected as a clinical candidate; however, further development was halted during phase II because of the observation of drug-induced agranulocytosis (DIAG) in two subjects.

2,4-Diamino-5-benzylpyrimidines as Antibacterial Agents. 4. 6-Substituted Trimethoprim Derivatives from Phenolic Mannich Inetrmediates. Application to the Synthesis of Trimethoprim and 3,5-Dialkylbenzyl Analogues
The preparation of a wide variety of 6-substituted trimethoprim analogues was readily accomplished by the reaction of 2,4-diamino-6-substituted-pyrimidines with 2,6-dimethoxy-4-phenol at 120-160 deg C.The less reactive 2,6-dialkyl-4-phenols reacted successfully with 2,4-diamino-6-(alkylthio)pyrimidines to give 5-(substituted benzyl)pyrimidines.The phenolic groups of the products were alkylated in high yield when a nonreactive 6-substituent was present in the pyrimidine ring. 6-(Alkylthio) groups were easily removed with Raney nickel.Trimethoprim was thus obtained in high yield from its 6-(methylthio) counterpart.The 6-substituted trimethoprim analogues all had low activity as inhibitors of Escherichia coli dihydrofolate reductase and as antibacterial agents.
