Building Blocks

Cyanodibenzylamine is a synthetic, pharmaceutical preparation. It is an amine that undergoes nucleophilic attack by an amide to form a cyanoguanidine. Cyanodibenzylamine can be used as a stabilizer and additive in pharmaceutical preparations. It also has the ability to bind metal hydroxides, which may be due to the presence of basic fibroblast growth factor and isoquinoline compound. Cyanodibenzylamine is also used as a polymerization initiator in organic chemistry, with hydrocarbon solvents such as benzene or toluene as its solvent.

2-Chloro-3-methylbenzylamine HCl is a fine chemical that is a versatile building block for synthesis of pharmaceuticals and research chemicals. It is also a useful intermediate in the production of other compounds, such as speciality chemicals, complex compounds, and reaction components. 2-Chloro-3-methylbenzylamine HCl has many potential applications in both academia and industry because it is a high quality reagent with many uses.

4-Chloro-2-fluorophenyl)acetic acid ethyl ester is a fine chemical that can be used as a scaffold for building more complex molecules, or it can be used as a versatile building block in the synthesis of research chemicals. It is also an intermediate in many reactions and can be used as a speciality chemical. 4-Chloro-2-fluorophenyl)acetic acid ethyl ester has been shown to have high quality and it is useful for research on complex compounds. It can also be used as a reagent in organic synthesis.

4,4'-Dihydroxy-2,2'-bipyridine is a metallo-organic compound that can be used as a homogeneous catalyst for the oxidation of hydroxyl groups. It is also used in cancer research because it has been shown to inhibit tumor cell proliferation and induce apoptosis. 4,4'-Dihydroxy-2,2'-bipyridine is an activated form of 2,2'-bipyridyl with a hydroxyl group on its ortho position. It can be prepared by reacting bromine with the metal salt of 2-hydroxybenzaldehyde in the presence of sodium hydroxide. This reaction produces two products: 4,4'-dihydroxy-2,2'-bipyridine and 2-bromoethanol. The deuterium isotope is used for nuclear magnetic resonance spectroscopy studies because it has a spin quantum number of one and does not cause chemical shift

(R)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine and its enantiomer (S)-2,5-Dihydro-3,6-dimethoxy-2-isopropylpyrazine are also known as Schöllkopf chiral auxiliaries or Schöllkopf reagents, and are used to produce optically pure α-amino acids via asymmetric synthesis. The Schöllkopf reagent can be deprotonated at the prochiral α-carbon, and the resulting enolate is trapped with electrophiles to yield adducts with high (typically > 95% d.e.) diastereoselectivity. The enolate is essentially planar, and the steric bulk of the isopropyl group directs the incoming electrophile to attack from the opposite face, yielding trans adducts. A wide range of electrophiles including alkyl halides, alkyl sulfonates, acyl chlorides, aldehydes, ketones, epoxides, thioketones and enones can be used. Hydrolysis, typically under mild acidic conditions, yields the non-substituted amino acid with high (typically > 95 e.e.) enantiopurity.

2,6-Diaminopurine is a nucleotide analogue that is synthesized from guanosine. It inhibits the enzyme ribonucleotide reductase and blocks the synthesis of DNA precursors, which are necessary for viral replication. 2,6-Diaminopurine has been shown to inhibit hiv infection in tissue culture and animal models by decreasing the levels of nucleotides in cells. This drug can be used as an anti-viral agent against HIV and other retroviruses. 2,6-Diaminopurine has also been shown to be effective against murine sarcoma virus. The compound binds to the enzyme ribonucleotide reductase, which is important for DNA synthesis, and prevents its activity by mimicking adenosine triphosphate (ATP). The binding of 2,6-diaminopurine to ATP results in a coordination geometry that causes a long hydrogen bond with one oxygen

4,4'-Dicyano-2,2'-bipyridine is a ligand that binds to molybdenum and has been used in the diagnosis of mitochondrial DNA. It has been shown to be an effective treatment for tropical diseases such as malaria. This drug binds to the molybdenum cofactor in the enzyme ribonucleotide reductase, thereby inhibiting the production of ATP. 4,4'-Dicyano-2,2'-bipyridine also reacts with formic acid and ruthenium to produce a redshifted product that can be detected by electron paramagnetic resonance spectroscopy.

Thieno[3,2-c]pyridine-7-carboxylic acid is an anticancer drug that belongs to the class of acid derivatives. It has been shown to be active against solid tumors and has been found to be effective in inhibiting tumor growth and proliferation. Thieno[3,2-c]pyridine-7-carboxylic acid is a prodrug that is activated by hydrolysis of the ester group. The activation process occurs through an enzymatic mechanism that requires two enzymes: carboxylesterase and cytochrome P450.
