Compostos Policiclícos

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

5-Methoxypsoralen is a light-activated compound, which is a naturally derived organic substance found in certain plants, particularly from the Apiaceae family. This compound functions as a furocoumarin that interacts with DNA through photoactivation, forming cross-links upon exposure to ultraviolet A (UVA) light. These cross-links disrupt DNA replication, ultimately inhibiting cell proliferation.

Isatin dianilide is an organic compound with the chemical formula C8H6N2O. It is a white solid that is soluble in water, ethanol and acetone. Isatin dianilide can be synthesized by reacting phenylacetic acid with ammonia and formaldehyde. Isatin dianilide has been shown to have efficient oxidation reaction with Baeyer-Villiger oxidation, which makes it suitable for industrial use. Isatin dianilide also has biological activities such as inhibition of aminopeptidase N and aminopeptidase M, which are enzymes involved in protein synthesis. Yields of isatin dianilide are high because it can be produced from the commercially available compounds isatin and amidine.

5-Methoxy-2,3-dihydroindoline is a methoxy compound that is substituted with a methyl group. It has been shown to be an effective hydrogen transfer agent in cyclopentenone reactions, and can also be used as a sensor for nitroaromatic compounds. 5-Methoxy-2,3-dihydroindoline can be synthesized by the reaction of methoxylated aniline with sodium ethoxide in acetonitrile. This reaction produces the desired product in high yield (70%), and it can also be used for the methylation of secondary amines in good yield (80%). 5-Methoxy-2,3-dihydroindoline is potently active when titrated against benzo[a]pyrene.

7-Azaindole is a reactive chemical that has been shown to be effective in the treatment of skin cancer, as well as hepatic steatosis. The compound can promote the transfer of hydrogen atoms and form a dimer with protonated nitrogen. 7-Azaindole reacts rapidly with nucleophiles such as amines, alcohols, and thiols to form covalent bonds. The reaction mechanism is characterized by an initial protonation step followed by nucleophilic attack or hydrogen transfer from the nucleophile to 7-azaindole. Kinetic studies have demonstrated that the rate of this reaction depends on the concentration of both reactants.
