5-bromo-1H-inden-2(3H)-one is an organic compound with a carboxyl group. It is a colorless solid that has high activity in the coupling of carboxyl groups with metal ions and can be functionalized. 5-Bromo-1H-inden-2(3H)-one is often used as a catalyst in the Suzuki reaction to synthesize 1,4,5,6 tetrahydropyrimidinones.

3-(3-Bromophenyl)-cyclobutanone is a chemical compound with the molecular formula of C8H6BrO. It is a peroxide that is synthesized by the lactonization of cyclobutanone with 3-bromophenol in the presence of an oxidizing agent such as potassium permanganate or hydrogen peroxide. The family of compounds that are synthesized using this reaction includes ketones, cyclobutanones, and oximes. The synthesis can be optimized by varying the substrate concentration and reaction time. This product has been used to synthesize lipase substrates with high yields and chemoenzymatic oxidation products.

6-Methoxy-2,3,4,9-tetrahydro-1H-beta-carbolin-1-one is a β-carboline alkaloid that is structurally related to harmaline and tetrahydroharmine. It has been shown to have antidepressant activity in animals. 6-Methoxy-2,3,4,9-tetrahydro-1H-beta-carbolin-1-one was analyzed by GC/MS and found to be present in the leaves of plants from the genus Tetraclinis. 6MHBC was also identified as a metabolite of diazepam in rat urine after administration of a single oral dose of 10 mg/kg diazepam. The observed β carboline metabolite was determined to be 6MHBC.

13-Ethyl-3-methoxy-8,14-secogona-1,3,5(10),9(11)-tetraene-14,17-dione is a homologue of the natural product pyrazinoic acid. It is a synthetic molecule that has been shown to be an effective modulator of gene expression in wild type and mutant strains of Escherichia coli. 13-Ethyl-3-methoxy-8,14-secogona-1,3,5(10),9(11)-tetraene-14,17dione has also shown activity against methicillin resistant Staphylococcus aureus (MRSA) and Mycobacterium tuberculosis. The structure of this compound is similar to the structure of protein synthesis enzymes such as ribosomal protein S12. The enzyme protease activity may be inhibited by this compound due to its structural similarity with proteins that are
