Flecainide is an anti-arrhythmic drug that belongs to the class of drugs called Class IA or Class IC antiarrhythmics. It is used to treat arrhythmias in adults and children who are at least 6 months old. Flecainide is a long-acting medication, which means it remains active for a long time. This drug has been shown to have a low risk of causing neutropenia in women who take it during pregnancy. Flecainide has also been shown to cause an increase in serum levels of amide and trichloroethanol (TCE). The amide metabolite is responsible for most of the pharmacological effects of flecainide. The conformation and antipyrine metabolites are active against some bacteria and fungi, but not against other microorganisms such as Mycobacterium tuberculosis.

4-Benzyloxy-3-bromobenzaldehyde (4BBA) is a natural product that has been found to have high affinity for the histone deacetylase (HDAC) enzyme. 4BBA shows low cytotoxicity in fibroblast cells, which are cells that synthesize collagen, and it may be used as a fluorescent probe for HDACs in marine sponges. 4BBA binds to the cytoplasmic side of the cell's nucleus and exhibits fluorescence when excited with light at 350 nm. This fluorogenic activity is due to the phenyl ring and should allow for visualization of HDACs on the surface of cells using microscopy techniques.

2-Hydroxy-4-methylbenzohydrazide (2HMBA) is a supramolecular ligand that can bind to the active site of PI3K and AKT, which are two signaling molecules. 2HMBA has been shown to suppress immunosuppressive activities in an assay that measures the suppression of T cell proliferation by human peripheral blood mononuclear cells. The ligand binds to the active site of the enzyme and prevents its interaction with ATP, thereby inhibiting PI3K/AKT signaling. It also has magnetic properties. 2HMBA is a macrocyclic compound with a chiral center at C-2, which is responsible for its activity.

2-(2-Ethylphenyl)acetic acid is a compound that is used to synthesize antihistamines. It has been shown to have potent antihistaminic activity in both the ileum and the stomach, which is stereoselective for the S(+) enantiomer. The 2-ethylphenyl group of this compound can be susceptible to alkylation by organometallic reagents such as piperidine, which can lead to side reactions with other groups on the molecule or other molecules in the reaction mixture. The 2-ethylphenyl group is also chiral, meaning that it has two different forms, or configurations.

N-Benzyl-2-hydroxyacetamide is a synthetic molecule that is used in the synthesis of other molecules. It is synthesized by reacting benzaldehyde with 2-aminoethanol in the presence of hydrochloric acid and sodium hydroxide.

Benzo[b]thiophen-5-ol is a chiral molecule that has been synthesized to be homochiral. It has an active site and selective epoxide hydration activity, which is the rate-limiting step of epoxide ring opening reactions. The mechanism of this reaction is the cleavage of a C–C bond in an epoxide substrate by an O–H or S–H bond in benzo[b]thiophen-5-ol. The nature of this mechanistic bond cleavage reaction is unknown, but it may be due to catalysis by a benzyl group.
