Design and Structure-Guided Development of Novel Inhibitors of the Xeroderma Pigmentosum Group A (XPA) Protein–DNA Interaction
摘要:
XPA is a unique and essential protein required for the nucleotide excision DNA repair pathway and represents a therapeutic target in oncology. Herein, we are the first to develop novel inhibitors of the XPA-DNA interaction through structure-guided drug design efforts. Ester derivatives of the compounds 1 (X80), 22, and 24 displayed excellent inhibitory activity (IC50 of 0.82 +/- 0.18 mu M and 1.3 +/- 0.22 mu M, respectively) but poor solubility. We have synthesized novel amide derivatives that retain potency and have much improved solubility. Furthermore, compound 1 analogs exhibited good specificity for XPA over RPA (replication protein A), another DNA-binding protein that participates in the nucleotide excision repair (NER) pathway. Importantly, there were no significant interactions observed by the X80 class of compounds directly with DNA. Molecular docking studies revealed a mechanistic model for the interaction, and these studies could serve as the basis for continued analysis of structure-activity relationships and drug development efforts of this novel target.

The present invention relates to a method for identifying compounds that modulate the activity of p300/CBP. Compounds of the invention are identified by designing or screening for a compound which binds to at least one amino acid residue of the newly identified lysine-CoA inhibitor binding site, L1 loop, electronegative pocket, or electronegative groove of the HAT domain of p300/CBP and testing the compound for its ability to modulate the activity of p300/CBP. Compositions and methods for preventing or treating diseases or disorders associated with p300/CBP are also provided as is a method for producing a semi-synthetic HAT domain.

An Rh(III)-catalyzed C–Hactivation of pyrazolones with 1,6-enynes was investigated. The regioselectivity of the C–Hactivation/alkyne insertion is readily solved by using symmetric enyne coupling partners, and a C–H activation-triggered cascade reaction is realized, which involves alkyne insertion, tautomerization, and double cyclization to offer a class of structurally complex polycyclic architectures

A palladium-catalyzed oxidative dehydrogenation reaction in the presence of AMS and base to synthesize pyrazolones and pyrazoles was identified. This method can be utilized to a wide range of substrates, operates under mild react conditions and can give high yields. We believe it could be used as an alternative protocol for the classical dehydrogenation reactions.
