based upon reported antagonists for the subtypes PAR1 and PAR2. Modified versions of the PAR1 antagonist RWJ-58259 containing alkyne adapters were connected via cycloaddition reactions to azide-capped polyethylene glycol (PEG) spacers attached to imidazopyridazine-based PAR2 antagonists. Initial studies of the PAR1-PAR2 antagonists indicated that they inhibited G alpha q-mediated calcium mobilization in

A facile and efficient synthesis of 6-amino and 6-aminoalkyl thiazolo[4,5-c]pyridazines is reported. The key step for the construction of this novel bicyclic scaffold was the reaction between 3-amino-4-bromopyridazine derivatives and alkylisothiocyanates. The application of this methodology for the synthesis of a small library of thiazolo[4,5-c]pyridazines is also described. (C) 2012 Elsevier Ltd. All rights reserved.
