Amidas

2-Phenyl-2-(2-piperidyl)acetamide is an enantiomeric amide that can be used as a chiral building block for the synthesis of other organic compounds. It is synthesized by reacting phenylacetic acid with piperidine. 2-Phenyl-2-(2-piperidyl)acetamide is a primary amide and has been shown to have analgesic properties.

3-(4-Methoxyphenyl)propionamide is a compound that belongs to the group of benzene amides. It is synthesized by reacting an excess of 3-bromopropionaldehyde with an amine in the presence of sodium hydroxide. This reaction produces a mixture of products, which are separated by chromatography. The yields for this reaction are approximately 90%. 3-(4-Methoxyphenyl)propionamide has been used as a biomolecular building block, and its traceless nature makes it useful in organic synthesis.
3-(4-Methoxyphenyl)propionamide can be used to synthesize alkanesulfonamides and spirolactams, which are important intermediates in chemical synthesis. 3-(4-Methoxyphenyl)propionamide also reacts with phenanthridone to produce chloride derivatives and with arenes to produce linkers.

Nonsteroidal androgen receptor antagonist

2-Chloro-5-nitrobenzene sulfonamide (2CNS) is a glycol ether that has been shown to inhibit the activity of carbonic anhydrase. It has been shown to be a competitive inhibitor of the enzyme, and can be used as a lead compound for developing new drugs. 2CNS has been shown to inhibit an anhydrase that is found in bacteria, such as Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. This inhibition causes increased levels of hydrogen ions in the bacterial environment, which leads to the acidification of their surroundings. 2CNS also inhibits chloride ion uptake in these bacteria.
2CNS's pharmacophore includes two aromatic hydrocarbon rings with at least one hydrogen bond acceptor group on each ring. This pharmacophore is responsible for its inhibition of carbonic anhydrase and chloride ion binding site.
