Flavone derivatives of formula (I), their optical and geometric isomers, mixtures and salts are new. R1 = alkyl; R2 = 3-9C cyclic hydrocarbon (optionally containing at least one intracyclic double bond and optionally substituted), 6-15C polycyclic hydrocarbon (optionally containing at least one double bond and optionally substituted) or 1-13C hydrocarbon (optionally containing one or more double and/or triple bond and optionally substituted); R3 = H or OH; Alk = e.g. 1-6C alkylene; X = O, -CR'= or -CHR'-; R' = H or alkyl; Y = e.g. -C IDENTICAL N, -C(=Z2)(R4), C(=Z1)(-O-R4), -C(=Z1)(N(R4)(R4')), N(R4)(R4'), -<+>N(R5)(R5')(R5'') Hal<->, -C(=Z1)(N(R4)(-OR4') or C(=N-R4'')(NR4R4'); Z1 = O or S; Z2 = O, S, =N-OR4 or =N(O)R5; R4, R4', R4" = H, optionally substituted alkyl, aryl, heteroaryl or cycloalkyl; R5, R5' , R5" = optionally substituted alkyl, aryl, heteroaryl or cycloalkyl; provided that: (i) the alkyl and alkoxy groups contain 1-6C and are optionally substituted by halog en and OH, the alkyl groups being optionally further be substituted by alkoxy; (ii) aryl is phenyl or naphthyl (optionally substituted by halogen, alkyl, OH and/or alkoxy; (iii) heteroaryl denotes furyl, thienyl, thiazolyl, isothiazolyl, oxazolyl, pyrrolyl, imidazolyl, pyrazolyl, pyridyl, pyrazinyl, pyrimidyl, pyridazinyl, indolyl, quinolyl, isoquinolyl or quinazolinyl (optionally substituted by one or more halogens, alkyl, OH and/or alkoxy). |
