Boc-Gly-OH is a cyclic peptide with a fatty acid acyl chain. It is synthesized by reacting the amino acid glycine with sodium carbonate in the presence of trifluoroacetic acid to form the intermediate Boc-Gly-OSu. The product is then reacted with allyl bromide in a second step to produce Boc-Gly-OCH2CH2Br and then reacted with calcium chloride to yield the final product. Boc-Gly-OH has been used as an HIV inhibitor, which may be due to its ability to bind to both CD4 and gp120 proteins on the surface of HIV. This binding inhibits viral entry into host cells by blocking protease activity and fusion of viral envelope with host cell membrane, leading to inhibition of HIV infection.

Leptin is a hormone that regulates energy metabolism by modulating appetite and body weight. Leptin is produced by fat cells and signals to the hypothalamus of the brain about how much fat tissue there is. It also helps regulate other metabolic processes, such as insulin resistance and glucose tolerance. Leptin has been shown to have an anorectic effect in rodents, which may be due to its ability to reduce food intake or increase energy expenditure. In humans, leptin levels are higher in obese individuals than in those with normal weight, which indicates that this hormone may play a role in obesity.
