  Probing the ATP Ribose-Binding Domain of Cyclin-Dependent Kinases 1 and 2 with O⁶-Substituted Guanine Derivatives

  摘要：

  O-6-Substituted guanines are adenosine 5'-triphosphate (ATP) competitive inhibitors of CDK1/cyclin B I and CDK2/cyclin A, the O-6 substituent occupying the kinase ribose binding site. Fifty-eight O-6-substituted guanines were prepared to probe the ribose pocket, and the structures of four representative compounds bound to monomeric CDK2 were determined by X-ray crystallography. Optimum binding occurs with a moderately sized aliphatic 06 substituent that packs tightly against the hydrophobic patch presented by the glycine loop, centered on Val18, an interaction promoted by the conformational restraints imposed in a cyclohexylmethyl or cyclohexenylmethyl ring. Structure-based design generated (R)-(2-amino-9H-purin-6-yloxymethyl)pyrrolidin-2-one (56), which reproduces the reported hydrogen bonds formed between ATP and Asp86 and Gln131 but failed to improve inhibitory potency. Thus, the parent compound O-6-cyclohexylmethylguanine (NU2058, 25) is the preferred starting point for exploring other areas of the kinase active site.

  Resistance-Modifying Agents. 8. Inhibition of O⁶-Alkylguanine-DNA Alkyltransferase by O⁶-Alkenyl-, O⁶-Cycloalkenyl-, and O⁶-(2-Oxoalkyl)guanines and Potentiation of Temozolomide Cytotoxicity in Vitro by O⁶-(1-Cyclopentenylmethyl)guanine

  摘要：

  A series of O-6-allyl- and O-6-(2-oxoalkyl)guanines were synthesized and evaluated, in comp ari son with the corresponding O-6-alkylguanines, as potential inhibitors of the DNA-repair protein O-6-alkylguanine-DNA alkyltransferase (AGT). Simple O-6-alkyl- and O-6-cycloalkylguanines were weak AGT inactivators compared with O-6-allylguanine (IC50 = 8.5 +/- 0.6 muM) With IC50 values ranging from 100 to 1000 muM. The introduction of substituents at C-2 of the allyl group of O-6-allylguanine reduced activity compared with the parent compound, while analogous compounds in the O-6-(2-oxoalkyl)guanine series exhibited very poor activity (150-1000 muM) O-6-Cycloalkenylguanines proved to be excellent AGT inactivators, with 1-cyclobutenylmethylguanine (IC50 = 0.55 +/- 0.02 muM) and 1-cyclopentenylmethylguanine (IC50 = 0.39 +/- 0.04 muM) exhibiting potency approaching that of the benchmark AGT inhibitor O-6-benzylguanine (IC50 = 0.18 +/- 0.02 muM). 1-Cyclopentenylmethylguanine also inactivated AGT in intact HT29 human colorectal carcinoma cells (IC50 = 0.20 +/- 0.07 muM) and potentiated the cytotoxicity of the monomethylating antitumor agent Temozolomide by approximately 3- and 10-fold, respectively, in the HT29 and Colo205 tumor cell lines. The observation that four mutant AGT enzymes resistant to O-6-benzylguanine also proved strongly cross-resistant to 1-cyclopentenylmethylguanine indicates that the O-6-substituent of each compound makes similar binding interactions within the active site of AGT.

  [EN] A range is disclosed of purine derivatives (I) which can act as inhibitors of cyclin dependent kinases (CDKs) and which thereby c an provide useful therapeutic compounds for use in treatment of tumours or other cell proliferation disorders. The compounds of this invention bind to CDK molecules in a manner that appears to be different to that of known CDK inhibitors such as olomoucine and roscovitine. In formula (I), in preferred embodiments: X is O, S or CHRx where Rx is H or C1-4 alkyl; D is H, halo or NZ1Z2 where Z1 and Z2 are each independently H or C1-4 alkyl or C1-4 hydroxyalkyl; A is selected from H, C1-4 alkyl, C1-4 alkoxy, hydroxy, CH2(CH2)nOH (n=1-4), and NRa1Ra2 where Ra1 and Ra2 are each independently H or C1-4 alkyl; B is selected from H, C1-4 alkyl, C1-4 alkoxy, CF3, an optionally substituted aryl (e.g. phenyl) or an optionally substituted aralkyl (e.g. benzyl), and an hydroxy group that provides a C=O tautomer; and Y is or includes an optionally substituted 4- to 8-membered carbocyclic or heterocyclic ring; or comprises an optionally substituted linear or branched hydrocarbon chain.
  [FR] L'invention porte sur une gamme de dérivés de purine (I) pouvant agir comme inhibiteurs des kinases dépendant de la cycline (CDK) et pouvant, par conséquent, produire des composés thérapeutiques destinés à être utilisés dans le traitement de tumeurs ou autres troubles de la prolifération cellulaire. Ces composés se lient à des molécules de CDK de façon à être différents de ceux produits par des inhibiteurs connus de CDK tels que olomoucine et roscovitine. Dans la formule (I), selon des réalisations préférées, X représente O, S ou CHRx, Rx représentant H ou alkyle C1-4; D représente H, halo ou NZ1Z2, Z1 et Z2 représentant chacun, indépendamment H, ou alkyle C1-4 ou hydroxyalkyle C1-4; A est sélectionné parmi H, alkyle C1-4, alcoxy C1-4, hydroxy, Ch2(CH2)nOH (n=1-4), et NRa1Ra2, Ra1 et Ra2 représentant chacun, indépendamment, H ou alkyle C1-4; B est sélectionné parmi H, alkyle C1-4, alcoxy C1-4, CF3, un aryle éventuellement substitué (tel que phényle) ou un aralkyle éventuellement substitué (tel que benzyle), et un groupe hydroxy qui produit un tautomère C=O; et Y représente ou comprend un noyau carbocyclique ou hétérocyclique à 4 ou 8 éléments; ou une chaîne d'hydrocarbure linéaire ou ramifiée, éventuellement substituée.
