一般說明

Deblock solution, containing dichloroacetic acid (DCA) in dichloromethane or Toluene, removes the dimethoxytrityl (DMT) protecting the group from the 5′ hydroxyl moiety of nucleotides already incorporated into the growing nucleic acid, prior to the addition of the next phosphoramidite. Removal of the DMT allows the unprotected 5′ hydroxyl moiety to react with a new phosphoramidite in a subsequent extension reaction.

應用

DCA Deblock (0.36M dichloroacetic acid in toluene) is suitable for the removal of 4,4Adimethoxytrityl (DMTr) protecting groups for the synthesis of antisense oligonucleotides in high yield and purity.

The metabolic phenotype that derives disproportionate energy via glycolysis in solid tumors, including glioma, leads to elevated lactate labeling in metabolic imaging using hyperpolarized [1-(13)C]pyruvate. Although the pyruvate dehydrogenase (PDH)-mediated flux from pyruvate to acetyl coenzyme A can be indirectly

The activation of oncogenic signaling pathways induces the reprogramming of glucose metabolism in tumor cells and increases lactic acid secretion into the tumor microenvironment. This is a well-known characteristic of tumor cells, termed the Warburg effect, and is a candidate

To investigate sensitization of metformin-cytotoxicity, cancer cells were treated with dichloroacetate (DCA), an inhibitor of pyruvate dehydrogenase kinase (PDK). Metformin-cytotoxicity was mainly dependent on glucose availability and reducing power generated by pentose phosphate pathway, whereas DCA cotreatment enhanced metformin-cytotoxicity via

Mitochondrial dysfunction is one of the pathogenic mechanisms that lead to neurodegeneration in Amyotrophic Lateral Sclerosis (ALS). Astrocytes expressing the ALS-linked SOD1(G93A) mutation display a decreased mitochondrial respiratory capacity associated to phenotypic changes that cause them to induce motor neuron
