  Discovery and SAR of 6-Alkyl-2,4-diaminopyrimidines as Histamine H₄ Receptor Antagonists

  摘要：

  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.

  A series of 2-amino-7, 8-dihydro-4-piperazinyl- and 4-amino-7, 8-dihydro-2-piperazinyl-6H-thiopyrano[3, 2-d]pyrimidines and related compounds were synthesized and evaluated for hypoglycemic activity. Several compounds exhibited excellent activity, and 7, 8-dihydro-2-(4-methyl-piperazinyl)-4-(1-pyrrolidinyl)- (8c, dimaleate : MTP-1307) and 2-amino-7, 8-dihydro-4-piperazinyl-6H-thiopyrano[3, 2-d]pyrimidine (18a, dimaleate : MTP-1403) were selected for further investigation.Oral administration of 8c and 18a at 50 mg/kg markedly improved oral glucose tolerance in ob/ob mice. In this test, buformin also showed activity, whereas tolbutamide produced no significant improvement.
