6-Chloroisatin is a potent inhibitor of bacterial growth that binds to the 50S ribosomal subunit. It has been shown to have strong inhibitory activity against tuberculosis and sulphamethoxazole-resistant strains of Mycobacterium tuberculosis. 6-Chloroisatin inhibits bacterial growth by binding to the 50S ribosomal subunit, thereby preventing protein synthesis and cell division. The electron deficient form of 6-chloroisatin reacts with the electron rich sulphamethoxazole by displacement of chloride ion from the sulphonamide ring, forming a regiospecific product that inhibits bacterial respiration. This reaction system is inhibited by activated carbon, which may be a potential therapeutic strategy for patients with drug resistant tuberculosis.

5-Ethylindole-2-carboxylic acid is an organic compound that is a decarboxylation product of indole. It can be obtained by catalytic dehydrogenation of ethyl ester or 5-ethylindole-2-carboxylic acid. It has been shown to inhibit the growth of bacteria and fungi, as well as to have anti-inflammatory properties.

Columbianadin is a coumarin derivative, which is a natural compound primarily extracted from plants in the Apiaceae family, such as Angelica species. This natural product possesses a unique molecular structure characterized by the presence of a coumarin skeleton, which is responsible for its diverse biological activities.

6-Bromoindole is a synthetic compound that has been shown to have significant anticancer activity in animals. 6-Bromoindole shows cytotoxicity against cervical cancer cells and has been shown to be active against leukemia cells, with the potential for use as a therapeutic agent for both solid tumor cancers and hematological malignancies. The synthesis of 6-bromoindole is based on an asymmetric Friedel-Crafts reaction, which uses hydrochloric acid as a catalyst. This product also shows significant antibacterial activity and has been found to be effective against LPS-stimulated RAW264.7 cells.
