Claim:
1. A compound of a formula wherein Ar is selected from optionally-substituted aryl and heteroaryl moieties, where said substituents are selected from halo, alkyl, haloalkyl, cyano and amino substituents; L 1 is selected from optionally-substituted divalent C 1 -C 4 alkylene moieties, where said substituents are selected from halo, alkyl and divalent methylene substituents; R 1 is selected from H, alkyl and divalent alkylene substituents and amino protecting groups; L 2 is selected from optionally-substituted divalent C 1 -C 3 alkylene moieties, where said substituents are selected from halo, aza (—NH—) and substituted aza (—NR 2 ) moieties, where R 2 is selected from alkyl and divalent alkylene substituents; E 1 and E 3 are N, and E 2 is CH; and E 4 -E 7 are independently selected from CH, CR 3 and N, providing at least one of E 4 -E 7 is N, and where R 3 is selected from methyl and halo substituents, or a salt of a said compound.
