Dimethyl acetylenedicarboxylate

Description:

Dimethyl acetylenedicarboxylate (DMAD) is an organic compound characterized by its structure, which features two carboxylate groups attached to a central acetylenic carbon framework. It is a colorless to pale yellow liquid with a distinctive fruity odor. DMAD is known for its reactivity, particularly in Diels-Alder reactions and as a Michael acceptor, making it valuable in organic synthesis for constructing complex molecules. The compound is soluble in organic solvents such as ethanol and ether but has limited solubility in water. It is also recognized for its potential toxicity and should be handled with care, as it can cause irritation to the skin, eyes, and respiratory system. In terms of stability, DMAD is relatively stable under normal conditions but can undergo polymerization or decomposition when exposed to heat or light. Its applications extend to the synthesis of various pharmaceuticals, agrochemicals, and other fine chemicals, highlighting its significance in the field of organic chemistry.

Dimethyl acetylene dicarboxylate

CAS: 762-42-5

Dimethyl acetylene dicarboxylate (DMAD) is an anti-infective agent that targets the pyrrole system in enzymes. It inhibits the synthesis of bacterial proteins and has been shown to have antiviral activity against HIV. DMAD binds to a specific site on the enzyme and prevents it from functioning normally. This causes a decrease in the production of proteins needed for cell division and can lead to cell death. DMAD also has been shown to inhibit the growth of bacteria by binding to receptor sites, preventing protein synthesis, and altering enzyme activity. X-ray diffraction data and x-ray crystal structures reveal that DMAD is a stable compound which forms stable complexes with metal ions. These complexes are formed through hydrogen bonding interactions with amino acid residues in the active site of enzymes.
