摘要： The invention relates to novel compounds, processes for their preparation and their use in protecting biological materials from radiation damage (radioprotection). Preferred compounds of the invention are those of Formula II, as follows: wherein W represents —N(R1R2) where R1 and R2 are not both hydrogen and where they may together form a 5, 6 or 7 membered ring structure, —NHN(R1R2), —NHR3N(R1R2), —NHR3OR2, —N(R3)R3OR2, —N(R1)R3OR3OR3, —OR3NR1R2, —OR3 or W represents piperidyl, piperazinyl, morpholinyl, thiomorpholinyl or diazepanyl each of which may be optionally substituted by C1 to C4 alkyl, C2 to C4 alkenyl, —N(CO)N(R1R2), —N(CO)OR1, —N(CO)OR3OH, —(CO)NR1R2, —R3(CO)NR1R2, —R3OR1, —OR1, —N(R1R2) or —NH—; R1 and R2 are the same or different and are selected from hydrogen, C1 to C4 alkyl or C2 to C4 alkenyl; R3 is a C1 to C4 alkyl or C2 to C4 alkenyl group or chain; Z is the same or different and represents N or CH; Z′ is the same or different and represents N or C; X represents CH, N or NH, where is a double bond when X is CH or N and a single bond when X is NH; X′ represents N or NH, wherein when X is CH or NX′ is NH and wherein X and X′ are different and further where is a double bond when X′ is N and a single bond when X′ is NH; Q represents H, alkoxyl, —NR1R2, F or Cl; Q1 is absent when Z′ is N and when Z′ is C it represents H, alkoxyl, —NR1R2, F or Cl; A represents a five to ten membered single or multiple ring structure with heterocyclic N or O located at the ortho position, said ring including optional double bonds, substitutions and/or other heteroatoms and pharmaceutically acceptable derivatives thereof.
