Inhibitors of leucine-rich repeat kinase 2 (LRRK2) and mutants, such as G2019S, have potential utility in Parkinson's disease treatment. Fragment hit-derived pyrrolo[2,3-d]pyrimidines underwent optimization using X-ray structures of LRRK2 kinase domain surrogates, based on checkpoint kinase 1 (CHK1) and a

Three series of novel 4,5-fused pyridazinones were synthesized as histamine H(3) receptor antagonists. The 2,5,6,7-tetrahydrocyclopenta[d]pyridazin-1-one 5q and 5,6,7,8-tetrahydro-2H-phthalazin-1-one 5u displayed high affinity at both rat and human H(3) receptors, and showed potent antagonist and full inverse agonist activity in functional
