5-Deazaflavin derivatives as inhibitors of p53 ubiquitination by HDM2
摘要:
Based on previous reports of certain 5-deazaflavin derivatives being capable of activating the tumour suppressor p53 in cancer cells through inhibition of the p53-specific ubiquitin E3 ligase HDM2, we have conducted an structure-activity relationship (SAR) analysis through systematic modification of the 5-deazaflavin template. This analysis shows that HDM2-inhibitory activity depends on a combination of factors. The most active compounds (e. g., 15) contain a trifluoromethyl or chloro substituent at the deazaflavin C9 position and this activity depends to a large extent on the presence of at least one additional halogen or methyl substituent of the phenyl group at N10. Our SAR results, in combination with the HDM2 RING domain receptor recognition model we present, form the basis for the design of drug-like and potent activators of p53 for potential cancer therapy.

DNA synthesis by human cytomegalovirus (HCMV)-infected human embryonic lung (HEL) cells in culture. In general, active compounds had moderate to low selectivity for viral vs host cell DNA synthesis. Nucleoside and acyclonucleoside analogs of 2-(3,5-dichloroanilino)purines inhibited both HCMV and cellular DNA synthesis at similar concentrations. 2-Amino-4-chloro-6-(3,5-dichloroanilino)pyrimidine and

irreversibly binding to the enzyme. Several 6-(alkylamino)uracils were weak inhibitors of DNA polymerases III; the optimum alkyl groups for enzyme binding were n-pentyl and n-hexyl, which apparently can occupy the planar enzyme binding site. The varied activities of 6-anilinouracils on a mutant DNA polymerase, resistant to 6-(phenylhydrazino)- and 6-(benzylamino)uracils bearing a p-OH or NH2 group, have altered
