Dantrolene sodium is a muscle relaxant that belongs to the group of pharmacological agents. It is used to treat muscle spasms and hyperactivity in patients with neuromuscular disorders. Dantrolene sodium inhibits calcium release by blocking the activity of the enzyme ryanodine receptor in skeletal muscle cells. This inhibition prevents uncontrolled contraction of muscles and reduces their energy consumption. The drug also has an effect on malignant hyperthermia, which is caused by an increase in the production of adenosine triphosphate (ATP) due to increased cellular metabolism. Dantrolene sodium can inhibit ATP synthesis, thus reducing energy production and stabilizing cell membranes, thereby preventing cell death in neurons and other tissues.

2-Bromocinnamic acid is a synthetic compound that inhibits the reactions of arylating agents with tissues. It has cytotoxic activity and can be used in the treatment of alzheimer's disease. The synthesis of 2-bromocinnamic acid begins with anhydrous acetonitrile, which is heated to form an anhydrous salt. This salt is then dissolved in water and treated with potassium iodide and sodium nitrite. The resultant mixture undergoes a series of reactions to produce 2-bromocinnamic acid, including the addition of molybdenum as a catalyst. The reaction also produces byproducts that are removed by extraction or distillation. Finally, it undergoes a chromophore change from yellow to red in the presence of air due to oxidation by atmospheric oxygen.

This activated compound reacts with D-serine in the presence of an organic base to form the benzyl ester of D-serine. The reaction can be carried out in one pot without isolation steps. The final step is an oxidative cleavage of the benzyl group by irradiation with ultraviolet light or exposure to hydrogen peroxide, yielding L-threonine benzyl ester hydrochloride as a white solid.

L-Alanosine is a nucleotide that is synthesized from adenosine and alanine. It is the first substrate in the synthetic pathway of l-alanosine. L-Alanosine has been shown to have antibiotic properties against gram negative bacteria, such as Escherichia coli and Klebsiella pneumoniae. L-Alanosine inhibits synthesis of bacterial cell walls by interfering with the enzymatic activity of bacterial ribonucleotide reductase, which converts ribonucleotides to deoxyribonucleotides. The molecule also inhibits protein synthesis by binding to the 30S subunit of bacterial ribosomes, preventing elongation of polypeptide chains. In vivo treatment with L-alanosine significantly reduced tumor size and increased levels of ATP in colorectal adenocarcinoma cells.
