Identification of HSP60 as a Primary Target of o-Carboranylphenoxyacetanilide, an HIF-1α Inhibitor
摘要:
We succeeded in the design and synthesis of multifunctional chemical probes of the HIF-1 alpha inhibitor carboranylphenoxyacetanilide (1) that combine photoaffinity labeling and click reaction to identify the target protein. HSP60 was identified as a primary target protein of 1 using the chemical probes 2 and 3. Furthermore, HSP60 inhibitor 4 suppressed hypoxia-induced HIF activation, indicating that HSP60 affects HIF-1 alpha accumulation directly or indirectly.
The carborane framework gives analogues able to induce20Sproteasomeactivities. A series of ortho‐carboranylphenoxy derivatives were synthesized as 20Sproteasome agonists, and carborane derivatives 11 a and 11 b were found to be potent inducers of the β1 and β2 activities of the 20Sproteasome. Since small‐molecule proteasome activators have not been developed, the carboranes described here have

The invention relates to a novel labeling reactant, suitable for labeling of a biospecific binding reactant using solid-phase synthesis. The invention further concerns new labeling methods. The novel labeling reactant has the formula (I)
wherein
A is a bivalent aromatic structure capable of absorbing light or energy and transferring the excitation energy to a lanthanide ion after the product made by the said solid-phase synthesis has been released from the used solid support, deprotected and converted to a lanthanide chelate;
R is - Z(G' - NH - X) G" - E, where
X is a transient protecting group;
E is a carboxylic acid, its salt, active ester or halide;
Z is the bridge point;
G is a bridge between A and Z, G' is a bridge between NH and Z and G" is a bridge between E and Z.
R' is -COOR''' where R''' is an alkyl of 1 to 4 carbon atoms, phenyl or benzyl.
