<p>7-Benzyl-2,6-dichloro-7H-purine is a reagent that is used in the synthesis of adenine and other purines. It can be synthesized by coupling 3-methylxanthine with aminoacids and organometallic reagents. This chemical can also be used to selectively synthesize 6-benzyladenine, which is an important precursor to pharmaceuticals. The 7-benzyl group on this chemical has been shown to act as a positional group in the catalytic hydrogenation of amines. This selective hydrogenation process has been found to be regioselective for cycloalkyl amines.</p>

<p>4-Phenyl-5-(pyridin-2-yl)-4H-1,2,4-triazole-3-thiol is a ligand that can be used to form supramolecular architectures. The compound has a coordination geometry of square pyramidal and exhibits anion recognition properties.</p>

<p>1-Ethynyl-4-(methylsulfanyl)benzene (EMSB) is a novel organometallic compound that has been shown to be an inhibitor of cyclooxygenases. EMSB inhibits cox-1 and cox-2, which are enzymes involved in the inflammatory response. Inhibiting these enzymes may lead to the reduction of inflammation, which is implicated in many diseases such as cancer, arthritis, and cardiovascular disease. EMSB has also been shown to have antiinflammatory activity in a gravimetric analysis of human neutrophils. This molecule has been shown to inhibit the production of prostaglandins by inhibiting the enzyme cyclooxygenase and x-ray diffraction data show that this molecule binds with high affinity to cox-1 and cox-2.</p>
