Patent ID: 7410975

Claim:
A quinazoline compound having a structural formula wherein X is an aryl or heterocyclic group, provided that if X is a phenyl group, NR 1 R 2 is part of a heterocycle or is a diamine NR 13 (CH 2 ) n NR 14 R 15 , wherein n is an integer from 2 to 6, inclusive, and R 13 , R 14 , and R 15 are each independently a hydrogen atom or an alkyl group; R 1 and R 2 are each independently a hydrogen atom or an alkyl, alkenyl, alkylamino, or aryl group, wherein R 1 and R 2 optionally are combined to form a heterocycle; Y is a sulfur atom, CR 9 R 10 , or NR 11 , where R 9 , R 10 , and R 11 are each independently a hydrogen atom or an alkyl, alkenyl, or aryl group, wherein any one of R 9 , R 10 , and R 11 optionally is combined with R 3 or R 4 to form a heterocycle; L is an alkyl or alkenyl group containing from 1 to 10 carbons or is an aryl group; R 3 and R 4 are each independently a hydrogen atom or an alkyl, alkenyl, or aryl group, wherein R 3 and R 4 optionally are combined to form a heterocycle; and R 5 , R 6 , R 7 , and R 8 are each independently a hydrogen atom, a halogen atom, or an alkyl, alkenyl, aryl, heterocyclic, nitro, cyano, carboxy, ester, ketone, amino, amido, hydroxy, alkoxy, mercapto, thio, sulfoxide, sulfone, or sulfonamido group, wherein any pair of R 5 , R 6 , R 7 , and R 8 which are adjacent one another optionally are combined to form a heterocycle or a carbocycle, and pharmaceutically acceptable hydrates and salts thereof.
