Rac-crizotinib is a racemate comprising equimolar amounts of (R)- and (S)-crizotinib. The active (R)-enantiomer acts as a kinase inhibitor and is used for the treatment of patients with locally advanced or metastatic non-small cell lung cancer. It has a role as an antineoplastic agent, a biomarker and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It contains an ent-crizotinib and a crizotinib.

Salbutamol, also known as albuterol, is a medication used to treat asthma, chronic obstructive pulmonary disease (COPD), and other respiratory conditions. It is a bronchodilator that works by relaxing the muscles in the airways, making it easier to breathe. In this paper, we will discuss the method of synthesis or extraction, chemical structure and biological activity, biological effects, applications, and future perspectives and challenges of salbutamol. Method of Synthesis or Extraction Salbutamol can be synthesized by several methods, including the reaction of 4-aminobenzenesulfonamide with 2-chloroacetyl chloride, followed by reduction with sodium borohydride. Another method involves the reaction of 4-aminobenzenesulfonamide with 2,2-dimethoxypropane, followed by reduction with lithium aluminum hydride. The efficiency and yield of each method vary, with the first method having a higher yield but also being more complex and requiring more steps. Environmental and safety considerations must also be taken into account, as some of the reagents used in the synthesis process can be hazardous. Chemical Structure and Biological Activity Salbutamol is a beta-2 adrenergic receptor agonist, which means it binds to and activates these receptors in the lungs, leading to bronchodilation. Its chemical structure consists of a phenethylamine backbone with a hydroxyl group and a tert-butyl group attached to the carbon atom. The hydroxyl group is responsible for the drug's activity, as it interacts with the receptor. Biological Effects Salbutamol has several biological effects on cell function and signal transduction. It activates the beta-2 adrenergic receptor, leading to the activation of adenylate cyclase and the production of cyclic AMP (cAMP). This, in turn, leads to the relaxation of smooth muscle cells in the airways, resulting in bronchodilation. Salbutamol also has potential therapeutic and toxic effects, depending on the dose and duration of treatment. At therapeutic doses, it is generally well-tolerated and has few side effects. However, at high doses, it can cause tremors, tachycardia, and other adverse effects. Applications Salbutamol has several applications in medical research, including its role in drug development and clinical trials. It is commonly used as a standard treatment for asthma and COPD, and has been shown to be effective in improving lung function and reducing symptoms. However, it also has potential side effects, such as tachycardia and tremors, which must be carefully monitored. In environmental research, salbutamol has been shown to have effects on ecosystems, particularly in aquatic environments, where it can accumulate and potentially disrupt the balance of the ecosystem. It also has a role in pollution management, as it is commonly found in wastewater and can be difficult to remove. In industrial research, salbutamol is used in manufacturing processes to improve product quality and efficiency. Health and safety considerations must be taken into account, as exposure to the drug can cause adverse effects. Future Perspectives and Challenges Despite its widespread use, there are still limitations in the use and study of salbutamol. For example, its long-term effects on lung function and overall health are not well-understood, and there is a need for more research in this area. Additionally, there is a need for more sustainable and environmentally-friendly methods of synthesis and extraction. Possible solutions and improvements include the use of renewable resources and the development of more efficient and less hazardous methods. Future trends and prospects in the application of salbutamol in scientific research include the development of new formulations and delivery methods, as well as the exploration of its potential in other areas, such as cancer treatment. In conclusion, salbutamol is a widely-used medication with several applications in medical, environmental, and industrial research. Its method of synthesis or extraction, chemical structure and biological activity, biological effects, applications, and future perspectives and challenges must be carefully considered in order to ensure its safe and effective use.
