BG45 is a mutant strain of the bacterium Lactobacillus plantarum that has been modified to express a protein that inhibits the growth of tumor cells. The BG45 bacterium is capable of inducing an inhibitory effect on cancer cell growth in vitro and in vivo. This inhibitory effect is due to the immunomodulatory effects of the bacterium, which are mediated by suppressing genes that are involved in immune response and lipid metabolism. Furthermore, BG45 has significant cytotoxicity when cultured with human cancer cells and suppressed tumor growth in murine xenografts. This bacterium also has lysine residues that can be used as an indicator for identifying nutrient-poor environments such as microenvironments, suggesting that it may have potential use as a probiotic for patients with gastrointestinal disorders. In vitro assays have shown that BG45 produces fatty acids, which may be responsible for its activity against tumors.

Pent-1-yn-3-ol is a low molecular weight compound that is classified as an amide. It is an intermediate in the biosynthesis of fatty acids and primary alcohols from acetyl-CoA. Pent-1-yn-3-ol also alkylates amides in proteins, and can be used for the synthesis of magnetic nanoparticles. In order to determine the effects of mononuclear alkali metal ions on organisms, methyl ethyl was added to a mixture of 10 mM potassium hydroxide (KOH) and water. The pH was then adjusted to 4 with hydrochloric acid (HCl). A magnetic stir bar was placed in the flask, and the solution was mixed magnetically at room temperature. The growth rate of Drosophila melanogaster was monitored over time by measuring its wet weight.

2,6-Dibromo-4-(2-hydroxyethyl)phenol is a conformationally flexible and crystallizable compound that is soluble in organic solvents. The compound has two equivalent 2,6-dibromophenols joined by an ether bond to form a dimer. In the crystal structure, dimers are connected by hydrogen bonds to form chains. Chains are then linked by torsion with hydrogen bonding to form the two-dimensional lattice. This polymer is asymmetric due to the different orientation of the phenolic groups in each monomer.

5-Chloro-2,2-dimethylpentanenitrile is a nonpolar solvent that can be used as a phase transfer catalyst and reagent for the synthesis of cyclopentanone derivatives. It is also used as a hydrolyzing agent for the synthesis of 1-bromo-3-chloropropane. 5-Chloro-2,2-dimethylpentanenitrile can be used to synthesize cyclic ketones from alkyl halides and 1,1'-oxydiacetonitrile with an acetone or isobutyronitrile as a catalyst.
