<p>Iodomethyl methyl carbonate is a carbapenem antibiotic that has been shown to have anti-influenza activity. It inhibits the cap-dependent endonuclease of the influenza virus, which prevents viral replication and release of new viruses. Iodomethyl methyl carbonate also inhibits the HIV integrase enzyme and may be used as an inhibitor for the treatment of HIV infection. This compound has antibacterial activity against bacteria that contain metallo-β-lactamase, such as Enterobacteriaceae. Iodomethyl methyl carbonate is stable in organic solvents, making it useful for chemical reactions.</p>

<p>4-Chloroquinoline-3-carbonitrile is an intermediate in the synthesis of the tyrosine kinase inhibitor pelitinib and the process for its synthesis has been described. The synthetic process starts from acetonitrile, which reacts with nitrous acid to produce 4-chloroquinoline-3-carbonitrile. The next stage involves the reaction of 4-chloroquinoline-3-carbonitrile with ethyl acetate in the presence of a catalyst to produce 2-(4'-chlorophenyl)ethyl acetate. This compound can then be reacted with phenylethylamine to form (2E)-N-[2-(4'-chlorophenyl)ethyl]-N-(2,6-dimethoxyphenyl)acrylamide, which is a key intermediate in the synthesis of pelitinib.</p>

<p>2,4-Dichloroquinoline-3-carbonitrile is a nitrosourea compound that inhibits cancer cells. It is activated by the addition of a reducing agent such as triethyl orthoformate and then reacts with an amine to form the corresponding N,N'-dichloroquinoline. The product of this reaction inhibits cancer cells by binding to DNA and inhibiting RNA synthesis. 2,4-Dichloroquinoline-3-carbonitrile has been shown to be effective against leukemia cells in vitro.</p>

<p>6-Hydrazinylpyridine-3-carboxamide is a coligand with high affinity for technetium, which is used in analytical chemistry. The compound has been shown to bind to the transcription-polymerase chain reaction (PCR) and monoclonal antibody binding sites of the human immunodeficiency virus type 1 (HIV-1). 6-Hydrazinylpyridine-3-carboxamide has also been shown to be an effective inhibitor of protein synthesis in animal cells and to inhibit tumor cell growth. Clinical trials have demonstrated that this compound can be used as an aneurysm sealant and as a cancer treatment.</p>

<p>3-Oxo-3-(3-thienyl)propanenitrile is a metabolite of 3-oxothiopropanal. It is an analog of prostaglandin, which has been shown to have antiinflammatory properties. 3-Oxo-3-(3-thienyl)propanenitrile has been used in the treatment of adjuvant arthritis and was found to inhibit the production of prostaglandins.</p>

<p>2-(Ethylamino)benzaldehyde (2-EABA) is a reactive, radiation-sensitive compound that can be used as a diagnostic agent. 2-EABA is the precursor of styryl dyes and coumarin derivatives. 2-EABA reacts with chloride to form an amide in the presence of hydroxyl groups. The amide reacts with aromatic hydrocarbons to produce cationic polymers. The reactive functional group of 2-EABA is an aldehyde group, which reacts with basic dyes to form diamines and diamides. In addition, it has been shown that 2-EABA can be used to detect chloride ions in water samples, owing to its high solubility in water.</p>
