Respiratory syncytial virus (RSV) is the cause of one-fifth of all lower respiratory tract infections worldwide and is increasingly being recognized as a serious threat to patient groups with poorly functioning immune systems. Our approach to finding a novel inhibitor of this virus was to screen a 20 000-member diverse library in a whole cell XTT assay. Parallel assays were carried out in the absence of virus in order to quantify any associated cell toxicity. This identified 100 compounds with IC50's less than 50 μM. A-33903 (18), a 1,4-benzodiazepine analogue, was chosen as the starting point for lead optimization. This molecule was moderately active and demonstrated good pharmacokinetic properties. The most potent compounds identified from this work were A-58568 (47), A-58569 (44), and A-62066 (46), where modifications to the aromatic substitution enhanced potency, and A-58175 (42), where the amide linker was modified.
New synthesis of 1,3-dihydro-1,4-benzodiazepin-2(2H)-ones and 3-amino-1,3-dihydro-1,4-benzodiazepin-2(2H)-ones: Pd-catalyzed cross-coupling of imidoyl chlorides with organoboronic acids

A new approach to the synthesis of 1,4-benzodiazepines and 3-amino-1,4-benzodiazepines, which employs the Pd-catalyzed cross-coupling reaction of an imidoyl chloride with an organometallic reagent as the key step, is described. A five-step synthesis of a
