2-Acylindazole compounds of formula I or formula II are disclosed. These compounds inhibit Coagulation Factor XIIa. They are useful to treat autoimmune diseases.
Microwave-assisted trans-halogenation reactions of various chloro-, bromo-, trifluoromethanesulfonyloxy- and nonafluorobutanesulfonyloxy-substituted quinolines, isoquinolines, and pyridines leading to the corresponding iodinated heterocycles

(Chemical Equation Presented) Microwave irradiation of certain chloro-, bromo-, trifluoromethanesulfonyloxy- and nonafluorobutanesulfonyloxy-substituted quinolines in the presence of acetic anhydride and sodium iodide leads, via a trans-halogenation process, to the corresponding iodides in high yield. Related conversions involving pyridines and isoquinolines can also be achieved under similar conditions.
Carbon isosteres of the 4-aminopyridine substructure of chloroquine: Effects on pKa, hematin binding, inhibition of hemozoin formation, and parasite growth

Unlike diprotic chloroquine (CQ), its two 4-aminoquinoline carbon isosteres (1, 2) are monoprotic at physiological pH. Compared to CQ, hematin binding affinity of 1 decreased 6.4-fold, and there was no measurable binding for 2. Although 1 was a weak inhibitor of hemozoin formation, neither isostere inhibited P. falciparum in vitro. Evidently, the CQ-hematin interaction is largely a function of its pyridine substructure, but inhibition of hemozoin formation and parasite growth depends on its 4-aminopyridine substructure.
