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.

8-Geranyloxypsoralen is a natural furanocoumarin, which is a secondary metabolite typically derived from plants, particularly those in the Rutaceae family. Its source lies predominantly in certain fruits and herbs, where it functions as a natural defense compound.

Thiamine tetrahydrofurfuryl disulfide is a thiamine derivative that has been shown to serve as a cofactor for enzymes such as peptidyl-prolyl cis-trans isomerase, which catalyzes the formation of peptide hormones. It also plays a role in the synthesis of polymers such as cellulose. Thiamine tetrahydrofurfuryl disulfide can be found in crystalline cellulose and is an important component of two-way crossover studies on peptide hormones. This drug has been shown to stimulate oxidative metabolism in cells and may have therapeutic potential for treating conditions associated with oxidative injury, such as stroke, head trauma, and heart attack.
Thiamine tetrahydrofurfuryl disulfide may also have a role in the development of inflammatory responses through its interaction with toll-like receptor 4 (TLR4).

2-Azaspiro[3.3]heptane HCI is a fine chemical that has many uses in research, manufacturing, and other industries.
