LFF-571 is a novel semisynthetic thiopeptide antibiotic with potent activity against a variety of Gram-positive pathogens, including Clostridium difficile. LFF-571 was generally safe and well tolerated in single and multiple oral doses in healthy subjects. There were no deaths, no serious adverse events, and no subject withdrawals due to an adverse event. The most common adverse event was diarrhea, gastrointestinal pain or distension was also noted. Similar to healthy volunteers, patients with C. difficile infections exhibited high fecal concentrations and low serum levels of LFF571. Novartis is developing oral LFF 571 for the treatment of Clostridium difficile infections. LFF 571 binds to bacterial elongation factor Tu (EF-Tu) in domain 2. Phase-II development is ongoing in USA and Canada.

Isopropyl β-D-1-thiogalactopyranoside (IPTG) is a molecular biology reagent that induces β-galactosidase activity in many bacteria. This compound is a molecular mimic of allolactose, a lactose metabolite that triggers transcription of the lac operon, and it is therefore used to induce protein expression where the gene is under the control of the lac operator. Like allolactose, IPTG binds to the lac repressor and releases the tetrameric repressor from the lac operator in an allosteric manner, thereby allowing the transcription of genes in the lac operon, such as the gene coding for beta-galactosidase, a hydrolase enzyme that catalyzes the hydrolysis of β-galactosides into monosaccharides. But unlike allolactose, the sulfur atom creates a chemical bond which is non-hydrolyzable by the cell, preventing the cell from metabolizing or degrading the inducer.
