Abstract: The subject of the present invention is specific lactone compounds which can be used as antioxidant agents in pharmaceutical or cosmetic compositions or in food products, the said compounds containing a naphthalene ring onto which two lactone units are grafte.

Abstract: Compounds of formula I: wherein A, B and D are respectively selected from the group consisting of: (i) CH, NH, C; (ii) CH, N, N; and (iii) CH, O, C; the dotted lines represent two double bonds in the appropriate locations; and where Z is selected from S, O, C(?O), CH2 and NH are disclosed for use in inhibiting DNA-PK.

Abstract: A method of synthesising a compound of formula (I): wherein RN1 and RN2 are independently selected from hydrogen, an optionally substituted C1-7 alkyl group, C3-20 heterocyclyl group, or C5-20 aryl group, or may together form, along with the nitrogen atom to which they are attached, an optionally substituted heterocyclic ring having from 4 to 8 ring atoms; from a compound of formula (III): comprising the steps of: (a) removing the allyl group from the compound of formula (III) with appropriate reaction conditions to yield a compound of formula (II): and (b) reacting the compound of formula (II) with a triflating agent to yield a compound of formula (I).

Abstract: Compounds of formula I: wherein A, B and D are respectively selected from the group consisting of: (i) CH, NH, C; (ii) CH, N, N;and (iii) CH, O, C; the dotted lines represent two double bonds in the appropriate locations; and where Z is selected from S, O, C(?O), CH2 and NH are disclosed for use in inhibiting DNA-PK.

Abstract: Compounds of formula l: wherein A, B and D are respectively selected from the group consisting of: (i) CH, NH, C; (ii) CH, N, N;and (iii) CH, O, C; are disclosed for use in inhibiting DNA-PK.
