Abstract:
1. A compound of formula I wherein Y is O or S; R1 represents from 1 to 3 substituents independently selected from OH, SH, halo, NO R2 represents from 1 to 3 substituents selected from halo, optionally substituted (lower alkyl, lower alkenyl, cycloalkyl or lower alkoxy); R3 is when R1 is 2 substituents one of which is OH, and the other of which is optionally substituted (lower alkyl, cycloalkyl-lower-alkyl or lower alkenyl), R3 is H or optionally substituted (lower alkyl, aryl, aryl-lower alkyl, arylcycloalkyl, cycloalkyl-lower alkyl, cycloalkenyl-lower alkyl, hetereoaryl-lower alkyl, hetereoaryl, or carbonyl lower alkyl); or when R1 is 2-propynyloxy and R2 is isopropyl, R3 is also benzyl which is substituted by 1 to 3 substituents selected from lower alkyl, lower alkoxy, halo, halo-lower alkyl, e.g. CF when R1 is 2-propynyloxy and R2 is isopropyl, R3 is also benzyl which is substituted by OH and a second and optionally third substituent selected from lower alkyl, lower alkoxy, halo, —O—CH(H or lower alkyl)-COO(H or lower alkyl); or when R1 is 2-propynyloxy and R2 is cyclopropyl, R3 is also optionally substituted lower alkyl or benzyl; or when Y is S and R1 is as defined above but not methoxy, R3 is also optionally substituted benzyl; or a compound selected from 4-(4-isopropyl-phenyl)-1-(3,4-diamino-benzyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one, 1-(2,6-dichloro-benzyl)-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one, 1-benzyl-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazoline-2-thione; 1-(3,5di-tert-butyl-4-hydroxy-benzyl)-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one, or 1-[3-(2-hydroxy-ethoxy)-benzyl]-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazoline-2-thione; or a pharmaceutically-acceptable and -cleavable ester, or acid addition salt thereof; and provided that when Y is O and R3 is lower alkyl or cycloalkyl, R3 is not isopropyl or cyclopentyl; or provided the compound of formula I is not 4-(4-isopropyl-phenyl)-6-methoxy-1-pyridin-3-ylmethyl-1.H.-quinazolin-2-one, 4-(4-isopropyl-phenyl)-6-methoxy-1-pyridin-2-ylmethyl-1.H.-quinazolin-2-one, 1-(6-chloro-pyridin-3-ylmethyl)-4-(4-isopropyl-phenyl)-6-methoxy-1.H.-quinazolin-2-one, 4-(4-isopropyl-phenyl)-6-methoxy-1-(5-nitro-furan-2-ylmethyl)-1.H.-quinazolin-2-one or 1-[2-(1.H.-indol-2-yl)-ethyl]-4-(4-isopropyl-phenyl)-6-methoxy-1.H.-quinazolin-2-one, 4-(4-isopropyl-phenyl)-6-methoxy-1-phenethyl-1H-quinazolin-2-one, 1-(2-hydroxy-2-phenyl-ethyl)-4-(4-isopropyl-phenyl)-6-prop-2-ynyloxy-1H-quinazolin-2-one, methanesulfonic acid 2-[4-(4-isopropyl-phenyl)-2-oxo-6-prop-2-ynyloxy-2H-quinazolin-1-ylmethyl]-phenyl ester, or acetic acid 2-[4-(4-isopropyl-phenyl)-2-oxo-6-prop-2-ynyloxy-2H-quinazolin-1-yl]-1-phenyl-ethyl ester, 5-allyl-6-hydroxy-1-isopropyl-4-(4-isopropyl-phenyl)-1. H.-quinazolin-2-one, 1-cyclopropylmethyl-4-(o-tolyl)-6-nitro-2(1H)-quinazolinone, 1-ethyl-4-(o-tolyl)-6-chloro-2(1H)-quinazolinone, 1-cyclopropylmethyl-4-(o-tolyl)-6-chloro-2(1H)-quinazolinone, 1-cyclopropylmethyl-4-(o-fluorophenyl)-6-chloro-2(1H)-quinazolinone, 1-cyclopropylmethyl-4-(m-chlorophenyl)-6-chloro-2(1H)-quinazolinone, 1-cyclopropylmethyl-4-(o-chlorophenyl)-6-nitro-2(1H)-quinazolinone.
