Patent ID: 8410266

Claim:
A compound according to Formula (I): or a salt thereof, wherein: one of R 2 and R 4 is a phenyl monosubstituted with (C1-C10) alkyl, —OR a optionally substituted with one or more of the same or different R b groups, —O—C(O)OR a , —O—(CH 2 ) m —C(O)OR a , —C(O)OR a , —O—(CH 2 ) m —NR c R c , —O—C(O)NR c R c , —O—(CH 2 ) m —C(O)NR c R c , —O—C(NH)NR c R c , —O—(CH 2 ) m —C(NH)NR c R c or —NH—(CH 2 ) m —NR c R c ; the other of R 2 and R 4 is a phenyl monosubstituted or disubstituted with R 8 ; R 2 and R 4 are different; R 5 is —NR c R c , CN, or (C1-C6) alkyl optionally substituted with one or more of the same or different R 8 groups; each R 8 independently is R a or R b ; each R a is (C1-C6) alkyl; each R b is —OR a , —OCF 3 , —NR c R c , halogen, —CF 3 , —CN, —NO 2 , —N 3 , —SO 2 NR c R c , —C(O)R a , —C(O)OR c , —C(O)NR c R c , —C(NH)NR c R c , —C(NR a )NR c R c , —C(NOH)R a , —C(NOH)NR c R c ; each R c independently is R a , hydrogen, or, alternatively, two R c are taken together with the nitrogen atom to which they are bonded to form a 5- to 8-membered cycloheteroalkyl or heteroaryl; and each m independently is 1 or 2.
