New antiprotozoals active against Philasterides dicentrarchi, the causative agent of scuticociliatosis in farmed turbot and Black Sea bass-bream, have been synthesised and tested. The most active compounds posses a piperazine ring, generally N-bonded to the heterocycle, and are the 1,8-naphthyridines, 2f and 5o, the pyridothienopyrimidine (7), and the pyridothienotriazines, 8, 9, 12d, 12f, 12h, 12m

A series of 8-cyanopyrido[3',2':4,5]thieno[3,2-d]-1,2,3-triazines, substituted at C-4 and C-7, were synthesized and evaluated as nitric oxide and prostaglandin E(2) inhibitors in murine peritoneal macrophages stimulated with bacterial endotoxin. Several compounds exhibited considerable activity, compounds 10 and 13 being the most interesting ones with IC(50) values of 11.2 and 3.4 microM on nitrites
