Fluorescent Substrates for Potential Use in Enzyme-Linked Immunosorbent Assay of Membrane-Bound Nucleic Acids
摘要:
A number of phosphorylated fluorochromes were synthesized and tested for the alkaline phosphatase-linked fluorescence assay of membrane-bound nucleic acids. 3-Hydroxy-N-2'-biphenyl-2-naphthalenecarboxamide phosphate ester (HBNP) was found to be the most suitable for the assay. Nonfluorescent HBNP is hydrolyzed by phospholipase bound to the probe DNA to the highly fluorescent 3-hydroxy-N,2'-biphenyl-2-naphthalenecarboxamide (HBN). HBN is insoluble enough in aqueous medium to precipitate on the nylon membrane. Spots containing as little as 5 fg of lambda DNA can be successfully detected on the membrane with HBNP.
SAR optimization studies on modified salicylamides as a potential treatment for acute myeloid leukemia through inhibition of the CREB pathway
摘要:
Disruption of cyclic adenosine monophosphate response element binding protein (CREB) provides a potential new strategy to address acute leukemia, a disease associated with poor prognosis, and for which conventional treatment options often carry a significant risk of morbidity and mortality. We describe the structure-activity relationships (SAR) for a series of XX-650-23 derived from naphthol AS-E phosphate that disrupts binding and activation of CREB by the CREB-binding protein (CBP). Through the development of this series, we identified several salicylamides that are potent inhibitors of acute leukemia cell viability through inhibition of CREB-CBP interaction. Among them, a biphenyl salicylamide, compound 71, was identified as a potent inhibitor of CREB-CBP interaction with improved physicochemical properties relative to previously described derivatives of naphthol AS-E phosphate.

Compounds and methods are provided for inhibiting a CREB-CBP protein-protein interaction in a sample. In some cases, the method includes modulating transcription of CREB in a cell that overexpresses CREB. Also provided are methods of inhibiting the proliferation of a cancer cell. The subject CREB transcription inhibitor compounds include a substituted salicylamide or a prodrug thereof. Methods of alleviating symptoms associated with cancer (e.g., Acute Myeloid Leukemia (AML) or Acute Lymphomblastic Leukemia (ALL)) in a subject in need thereof are also provided. Pharmaceutical compositions including the subject compounds find use in treating cancer. The subject compounds may be formulated or provided to a subject in combination with a second agent, e.g. an anticancer agent.

ortho-Hydroxynaphthalene carboxamides have been identified as inhibitors of HCMV DNA polymerase. SAR investigations have demonstrated that both the amide and hydroxy functionalities are required for activity. Substitution on the naphthalene ring has led to inhibitors with submicromolar IC(50)s against HCMV polymerase. These compounds have been found to be >100-fold selective for inhibition of HCMV polymerase versus human alpha polymerase and display antiviral activity in a cell-based plaque reduction assay.
