Abstract: The present invention is in the area of novel compounds and salts thereof, their syntheses, and their use as anti-cancer agents. The compounds include compounds of Formula I: and solvates, hydrates and pharmaceutically-acceptable salts thereof, wherein A1 is N or CR1; A3 is N or CR3; A5 is N or CR5; R1, R3-R6 and L are defined in the specification; n is 0 or 1; and X is an optionally-substituted aryl group having 6-10 carbons in the ring portion, an optionally-substituted 6-membered heteroaryl group having 1-3 nitrogen atoms in the ring portion, an optionally-substituted 5-membered heteroaryl group having 0-4 nitrogen atoms in the ring portion and optionally having 1 sulfur atom or 1 oxygen atom in the ring portion, or an optionally-substituted heteroaryl group in which a 6-membered ring is fused either to a 5-membered ring or to a 6-membered ring, wherein in each case 1, 2, 3 or 4 ring atoms are heteroatoms independently selected from nitrogen, oxygen and sulfur.
