1-(2-Hydroxy-4-nitrophenyl)ethan-1-one (KPNE) is a potassium salt of a diketone that has antitubercular activity. KPNE inhibits the growth of Mycobacterium tuberculosis and has been shown to be effective as an antitubercular agent in animals. KPNE also has antiviral properties, inhibiting the RNA polymerase in HIV, which may be due to its ability to inhibit the synthesis of DNA. The mechanism of action for KPNE is thought to be due to its hydrolysis into 4-aminosalicylic acid, which inhibits bacterial protein synthesis by inhibition of the enzyme dihydrofolate reductase.

2-Ethyl-N-methylaniline is a colorless liquid that has a pyrrole ring and an indole group. It is used in the production of potassium and indoles, as well as in the synthesis of other organic compounds. 2-Ethyl-N-methylaniline also has pyrrole properties, which are similar to those of pyrrole. This chemical was first created by the German chemist Emil Fischer in 1887.

2-(Cyclohexyloxy)ethanol is a synthetic, xylene-based glycol ether. It has been shown to have synergistic effects with boron trifluoride etherate, germanium trioxide, and alkyl substituents. 2-(Cyclohexyloxy)ethanol has an antibacterial activity against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). This compound also has a constant rate of degradation and can be used in peptide binding studies.

3-(2,4-Dimethylphenyl)propionic acid is an organic compound that belongs to the class of propionic acid derivatives. It is a chiral compound with two stereoisomers. The crystal structure of the racemic mixture has been determined by x-ray crystallography and the absolute configuration was assigned as (S) based on its enantiomeric excess. 3-(2,4-Dimethylphenyl)propionic acid can be synthesized from benzyloxymethyl chloride and propionic acid. This reaction is mediated by a base, such as sodium methoxide or potassium t-butoxide.
3-(2,4-Dimethylphenyl)propionic acid is used in the synthesis of other compounds, such as phenylethyl propionate and 2-methylbenzaldehyde.

3-(Pyridin-3-yl)propanal is a potential anticancer agent that has been shown to cause apoptosis in DU145 cells. 3-(Pyridin-3-yl)propanal inhibits the kinase activity of 3-kinase, leading to the phosphatidylinositol pathway and the activation of caspases. This compound also has potent anti-proliferative activities in cancer cells, and may be used as an anticancer agent. 3-(Pyridin-3-yl)propanal was found to inhibit the proliferation of U937 cells in vitro by inducing apoptosis and inhibiting cell cycle progression at G1 phase.

Spiro[5.5]undecan-2-one is a reactive intermediate that can be generated by the aldol reaction between acetaldehyde and acetone. It is also produced in the olefination of methyl acrylate with 2-bromoethanol, and intramolecular aldol condensation of cyclopentenone with itself. Spiro[5.5]undecan-2-one has been shown to be an effective inhibitor of DNA gyrase, which is an enzyme that maintains the integrity of bacterial DNA. This active form binds to the 16S ribosomal RNA and inhibits protein synthesis, leading to cell death by inhibiting the production of proteins vital for cell division.

3-Bromo-2,3-dihydro-4H-chromen-4-one is a borohydride reduction and molecular modeling study of an analog of the natural product. The 14α-demethylase enzyme catalyzes the conversion of 3β,14α-dihydroxyandrostane to 3β,14β-dihydroxyandrostane. This enzyme has stereoselective activity in the synthesis of androgens from progesterone. The hydrogen bond interactions between the active site residues and solvent molecules are important for the enzymatic activity.

2-Methylcoumaran is a functionalized coumarin. It is synthesized by the reaction of 2-methylcoumarin with an alkylating agent such as acetyl chloride or benzoyl chloride. This reaction involves the substitution of one of the hydroxyl groups in 2-methylcoumarin with an alkyl group, forming a new bond between the two carbon atoms. The resulting product has two new functional groups, which can be used in organic reactions.
