摘要:
Compounds of formula (I) or their pharmaceutically acceptable salts, or their stereoisomers or mixtures of stereoisomers, where: R1 is selected from the group consisting of: phenyl, and phenyl mono-, di-, or tri-substituted by a radical independently selected from the group consisting of F, Cl, Br, I, (C1-C6)-alkyl, COO—(C1-C6)-alkyl, and (C1-C6)-alkoxy; and R2 is a radical selected from the same group as R1, further including a phenyl substituted in 4-position by a radical independently selected from the group consisting of —O(CH2)CONH(CH2)3CH3 and OCH2COOC(CH3)3, a biphenyl-4-yl, thiazol-2-yl, and a thiazol-2-yl mono- or di-substituted by a radical selected from F and phenyl; inhibit cell proliferation of tumor cells independently of p53 protein and may also induce apoptosis in several tumor cells independently of p53 protein, being useful for the treatment of several types of cancer.

摘要:
The present invention relates to a polymer composed by two to ten monomers of formula (I) as well as to a process for its preparation and its use as fluorophore wherein: X is a radical of formula (II) wherein —R5 is an electron pair or a (C1-C3)-alkyl radical; —Ra and —Rb are radicals independently selected from the group consisting of H, (C1-C4)-alKyI, (C1-C4)-alkoxy, (C1-C4)-alkylamino, phenyl, F, Cl, Br, amino, hydroxy, and nitro or —Ra and —Rb are fused forming with the carbon atoms to which they are attached a ring of formula (III) with the condition that (I) when —R5 is an electron pair, a is a N═C double bond, and Ra and Rb are fused forming the ring (III), said ring being a biradical selected from (IIIa) and (IIIb), thus, radical (II) is (IIa) or (IIb) respectively (II) when —R5 is a (C1-C3)-alkyl radical, a is a N—C single bond and Ra and Rb are fused forming the ring (III), said ring being a biradical (a), thus, the radical (II) is (IIc) R1-R4 and R7-R18 represent radicals, same or different, selected for the group consisting of H1 (C1-C4)-alkyl, (C1-C4)-alky-lamiπo, phenyl, F, Cl, Br, amino, hydroxy, and nitro; p is an integer from 0 to 1; R6 is a biradical selected from the group consisting of —CO—; —CONH(CH2)mCO—; and —CO[NHCHR″CO]m—, wherein —R″ are side chains radicals, same or different, corresponding to natural aminoacids; and m is an integer from 1 to 3; Z is a triradical of formula (IV) wherein r is an integer from 0 to 1; v is an integer from O to 1; Z′ is a triradical selected from —CH2— and nitrogen; Z″ is H, with the proviso that: (a) when Z′ is nitrogen, forming an amide bound with R6, then is hydrogen and v is an integer from O to 1, and (b) when Z″ is —NH—, forming an amide group with R6, then Z1 is —CH2 and v=O or of formula (V) wherein Z″ is selected from —CH3 and —CH2NH—, Z1v is selected from H and NH, Zv is selected from S and O atom, W is an integer from 0 to 1, with the proviso that (c) when R6 is bound to Z′″ then Z′″ is —CH2NH—, Z1v is hydrogen and w is 0; and (d) when Z1v is —NH— forming an amide bound with R6, Z′″ is —CH3 and w is 1; and and wherein the monomers of formula (I) are linked through the triradical Z, forming an amide or phosphate bound.
