Claim:
A compound of formula I: and isomers, salts, solvates, chemically protected forms, and prodrugs thereof; wherein: one of P and Q is O, and the other of P and Q is CH, where there is a double bond between whichever of Q and P is CH and the carbon atom bearing the R 3 group; Y is either O or S; R 1 and R 2 together form, along with the nitrogen atom to which they are attached, a morpholino group; R 3 is a first phenyl group, attached by a first bridge group selected from —S—, —S(═O)—, —S(═O) 2 —, —O— and CR C1 R C2 —, to an optionally substituted second phenyl group; the first phenyl group and the second phenyl group being optionally further linked by a second bridge group selected from —S—, —S(═O)—, —S(═O) 2 —, —O—, CR C1 R C2 —, —CR C1 R C2 CR C1 R C2 —, —C═O, —CR C1 R C2 S—, —CR C1 R C2 O—, —SCR C1 R C2 —, —OCR C1 R C2 —, —RC═CR—, or a single bond, which is bound adjacent the first bridge group on both groups so as to form an optionally substituted C 5-7 ring fused to both the first phenyl group and the second phenyl group, the first phenyl group being further optionally substituted; R C1 and R C2 are independently selected from hydrogen, an optionally substituted C 1-7 alkyl group and an optionally substituted C 5-20 aryl group; wherein the first phenyl group in R 3 optionally bears a substituent selected from the group consisting of an amino group, a hydroxy group, a halo group, an acylamido group, a sulfonamino group, an alkoxy group, an acylkoxy group, an alkyl group, a nitro group, a cyano group, a thiol group, an alkylthio group, and an acyl group; and wherein the second phenyl group in R 3 optionally bears a substitutent selected from the group consisting of an acylamido group, an ester group, an amido group, an amino group, an acyl group, a sulfonamino group, an ether group, and a carboxy group.
